This site meets the Ministry for the Environment Hazardous Activity and Industry List classification for Category A - Chemical manufacture, application and bulk storage, Activity 17 - Storage tanks or drums for fuels, chemicals or liquid waste. A 2000 Soil Test Investigation by Montgomery Watson was undertaken after an underground fuel storage tank had been removed (December 1999). The report indicated that hydrocarbon concentrations were within the 'Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand', so no further action was recommended with respect to residual contamination resulting from the use of the underground storage tank.
The tank was replaced by an aboveground storage tank (1700L) located within the building.

The municipal gasworks were established at this site in 1887 and continued to be used until 1910 when the works moved to another location (see file number SN/06/034/02). A gasholder continued to be used until the 1940s and the site was used as a council yard until the 1960s. A site investigation undertaken by Pattle Delamore Partners Ltd (March 2000) revealed 'concentrations of polycyclic aromatic hydrocarbons to be in excess of residential guideline values, for much of the site, at depths of less than 0.2 m'. An elevated lead concentration was also detected. A follow up report, undertaken by Pattle Delamore Partners (August 2000) recommended that 'some form of control be exercised over significant exposure pathways, in particular children playing in exposed ground, gardening activities and consumption of home grown produce'. A further site assessment was undertaken on neighbouring properties due to a proposed subdivision. Shallow soil samples found that contaminants originating from the gasworks exceeded the guidelines for residential land use by significant amounts. It is unclear what remediation or measures, if any, have been undertaken to reduce the risk to residents.

The mill was established on the site in the 1960's. Timber treatment was undertaken at the site from the early 1980's using a dip tank containing boric preservatives. This practice ceased in 1994. In the early 1980's a spray tunnel was used to apply antisapstain to the wood. However, in the mid 1980's this changed and the wood was treated with antisapstain and boric preservative in the same dip tank. During the period in which the plant was operated a number of different antisapstains were used, and some of these contained pentachlorophenol. The site around the dip area and the spray tunnel was not sealed or bunded at the time of the site visit (1998). When treated timber was removed from the dip tank, it was stored undercover. Analysis of a composite sample made up of three soil samples taken from the site indicated elevated levels of boron (this sampling was undertaken in 1998). It is possible that there are other contaminants such as PCP present in the soil and groundwater.

The site has been used as a service station, transport depot and motor vehicle workshop. As part of these operations the site had a number of underground storage tanks (USTs).
Information received (URS reports, 2008) shows that all the USTs have been removed from the site. During the removal of the USTs some petroleum hydrocarbon contamination was found in the surrounding soil and groundwater. Before a new building was constructed on the site, the contaminated soil was excavated and removed from the site. However, some contaminated material may remain underneath the footpath at the southern end of the site as this was not able to be excavated. A number of groundwater monitoring wells have been constructed to monitor the contaminated groundwater. While the contamination in the groundwater is decreasing, it is still present. As at July 2008 it is proposed to install further monitoring wells to establish the true extent of the contaminated groundwater plume, and continue to monitor the groundwater for a further 12-18 months. Full results can be found in the file.
An AECOM Groundwater Monitoring Event report (2015) was received which details the monitoring of the hydrocarbon plume undertaken in September 2015. The results of this monitoring event indicates that the area of the plume containing hydrocarbon compounds has reduced significantly since monitoring began in 2007.

The site has been used as a service station and for the servicing/maintenance of motor vehicles. In February and April 2005 all fuel storage tanks were removed from the site and an investigation undertaken in accordance with the "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand" Ministry for the Environment 1999. The results of the investigation showed that the residual concentration of hydrocarbons on the site met the criteria for commercial /industrial use. However, in one sample, the naphthalene concentration exceeded the guideline for the protection of groundwater. Given that a sample down hydraulic gradient of this sample did not exceed guideline values and that groundwater in the area is not used for potable use, it is consider that this contamination does not pose a significant risk to the environment. No investigation has been undertaken to determine what, if any, contamination from the workshop activities is present on the site.

This site has been used as a landfill. Current land uses are residential, recreational and agricultural. The site was operated through the early 1950s up until 1965 and received general domestic refuse. Given the age and size of the site landfill gas generation is expected to be low. The location of the pensioner flats on the fill means there is some potential for build-up of gas depending on their construction. 'Accordingly the site is considered medium priority for further action with respect to landfill gas impacts'. No groundwater sampling has been undertaken (Landfills in the Wellington Region 'Wellington Regional Council Technical Report' 1998).

2006: The site was used by the Carterton Council from the 1920's to the 1960's for the disposal of wastes. The wastes included car bodies, tree stumps and clean fill. Domestic wastes were not disposed of at the site. The lack of putrescible wastes would indicate that it is unlikely that any significant volumes of landfill gases have been generated. However, there is potential for the discharge of contaminants to the groundwater.

Ex Carterton Gasworks
The site was used as a gasworks from 1907 until the late 1950s. As part of these operations two gasholders were installed on the site along with tar tanks, condenser, purifiers and a retort house. In a desktop report produced for Greater Wellington Regional Council, it was identified that some of the wastes generated by the plant had been disposed of on site, however, not all the wastes could be accounted for. Greater Wellington Regional Council does not hold any record of site investigations having been undertaken on site.
Information received (URS, 2007) shows that an environmental site assessment was undertaken on the site. The assessment involved the visual inspection of test pits which confirmed the presence of gasworks waste such as clinker and coal, but no testing of the soil was done. A site management plan was developed to manage the current commercial/industrial land use of the site.

This site has been used for concrete manufacture and has stored hydrocarbons in bulk quantities. A small portable concrete batching plant was based at the site in the mid 1980's. However most of the mixing was done on sites remote from this property. It is possible that a storage tank containing hydrocarbons was used on this site however no Dangerous Goods Licence is held by Greater Wellington Regional Council.
Information received (URS report, July 2008) shows that an underground storage tank (UST) containing waste oil was removed from the site. Over 10,000 kg of bedding material was also removed from the site at the time of excavation. Soil samples taken of soil remaining on site were found to comply with Ministry for the Environment guidelines. The report states that the site is an active bitumen and asphalts blending, storage and aggregates crushing plant. The site is also an operational petroleum handling facility, and contains a motor vehicle workshop. There are pictures showing both USTs in use and mobile petroleum facilities.

Pattle Delamore Partners Limited (PDP) were engaged by the property owners to review the SLUR listing and the extent of the identifying polygon. PDP undertook an assessment of the site including reviewing the Masterton District Council (MDC) property records, discussions with staff, installation of groundwater monitoring bores and analysis of soil and groundwater samples.
An underground diesel tank was originally located on the eastern side of the dining room at the rear of the property and supplied a boiler located underneath the dining room. To facilitate the construction of a new wing in December 1991, the tank was moved to the western side of the dining room, where it is currently located. New pipework was installed to connect the tank to the boiler. There is no information in the property file relating to whether the pipework from the original tank location was removed or not. The Dangerous Goods Licence, which dates to March 1976, indicates that only one diesel tank has been present at a time. A transformer is located at the rear of the building, adjacent to the underground tank (CNMG-13-350)
Eight soil samples and four water samples were reportedly analysed for total petroleum hydrocarbons (TPH) and one of the water samples was also analysed for polycyclic aromatic hydrocarbons (PAH). All of the samples analysed recorded concentrations below the laboratory’s limit of reporting. Following approval from WorkSafe the tank has subsequently been slurry-filled (owing to its close proximity to an electrical transformer).
Information supplied by PDP (CNMG-13-312 and CNMG-13-350) was reviewed by a suitably qualified and experienced practitioner.
The extent of the identifying polygon was reduced to the area where the HAIL activities were undertaken, no changes have been made to the classification of this site (CNMG-13-324).

Tinui (BP)
ALFREDTON TINUI RD
This site has previously been used as a council works depot since at least 1960 and possibly since 1930. The site was used to service the area. Trucks and machinery were refuelled on the site when required. A large garage which houses the town fire engine also exists on the property. Two underground storage tanks were removed in 1993. Soil sampling for total petroleum hydrocarbons (TPH) undertaken at the time found that the soil was contaminated to a depth of 2 meters (BP Site Investigation 1993). It was thought likely that the source of this contamination was from a small steady leak occurring from the fittings leading to the tank over a long period of time.
Further sampling of the site was undertaken in August 2000 by URS. This site investigation concluded there is a possibility of encountering odorous oil and or groundwater during future excavations in some areas of the site. However, in terms of the Tier 1 acceptance criteria given in the Oil Industry Guidelines, 'the levels of residual hydrocarbons do not pose a significant risk to human health in respect to residential and commercial/industrial land uses of the site'.

2024-Masterton Park Bowling Club’s first record of being open is from 1916 and has two greens - one grass and one artificial. The artificial turf was tennis courts in the 50’s. Sports turfs are often very intensively managed to control weeds, insect pests and fungal diseases. Historically DDT, dieldrin and arsenic-based pesticides were used to control insects in turf until the last remaining arsenic based herbicide (methylarsenic acid MSMA) was deregistered in 2010. While the use of DDT to control grass grub in pasture was banned in 1970, DDT could still be used under permit to control grass grub in playing fields and bowling greens. Pentachlorophenol was used on turf to control moss and Endosulfan was used to kill earthworms in sports turf, which was permitted for use in New Zealand until 2008. A range of mercury-based fungicides were also available in New Zealand and are likely to have been used to control fungal diseases in turf. Evidence of the HAIL activity was verified by reviewing historical images, NZ archives and the club’s website. Greater Wellington holds no further information.

July 2019:
This site is currently used as a service station and has in the past been used as an uncontrolled landfill, reportedly receiving demolition material relating to the 1942 Wairarapa earthquake.
Geotechnical investigation in May 2018 encountered hydrocarbon odour in bore hole 2 (BH02/ BP34/0194) located near the current LPG tank.
An Assessment of Environmental Effects (AEE) report was received from Jacobs NZ Ltd as a proposed redevelopment and upgrade of the service station and infrastructure required a resource consent application for the dewatering the site during construction. The AEE included a site history description and a PSI (Appendix E).
The AEE summarised the findings of the PSI and noted ‘localised hydrocarbon impact to groundwater’ and that the site could potentially contain asbestos containing material (ACM) arising from asbestos from housing insulation in the uncontrolled fill and buried sewer and stormwater mains pipes.
The current site is described in the AEE as: ‘ underground petroleum storage system (UPSS) located on the site includes three tanks located south of the shop building, with two 40,000 litre petrol tanks and one 30,000 litre diesel tank. The LPG tank is located to the east of the shop building. There are nine dispenser units; four petrol, two diesel and two LPG located under the forecourt canopy, and one diesel dispenser located southeast of the shop for the truck stop.’
This site has been reclassified as Contamination Confirmed and will be subject to further review if sufficient information is available in the future.

This site has been used as a landfill up until approximately 1960. It is assumed that general refuse was disposed of this site. According to 'Landfills in the Wellington Region' Wellington Regional Council Technical Report, (1998) the site was considered medium priority with respect to the discharge of leachate given the potential effects on Motuwaireka Stream and its users. No sampling has been undertaken for this site.

This site was an old gravel reserve which has been used as a landfill accepting general refuse. The site was assessed as part of 'Landfills in the Wellington Region' - A Wellington Regional Council Technical Report (1998). The results indicated a discharge of leachate into the Kopuaranga River (which is valued for fish). While in general the level of contaminants were below ANZECC criteria for both aquatic ecosystems protection and stock watering, some further sampling was considered warranted to adequately characterise the effects of the discharge on the environment. Greater Wellington does not hold results to suggest any further sampling has been done. The site is now used for hardfill.

COLOMBO RD
This site was previously a gravel quarry which was later filled with waste material. Fill materials included general refuse, gas works waste and army refuse (from WW II camps). Soil sampling undertaken in 2000 found that the concentrations of PAH (polycyclic aromatic hydrocarbons) exceeded guideline criteria for residential use considerably.
This site is now a Masterton District Council owned recreational reserve.

Former Mobil Masterton Truckstop
2007: This site has stored hydrocarbons in bulk quantities and has been used as a truckstop. An environmental assessment was undertaken by PDP in 1996. A plume was discovered on the surface of the one groundwater monitoring well and elevated levels of petroleum hydrocarbons and polycyclic aromatic hydrocarbon concentrations at another.
Further sampling undertaken in 2000 found that the hydrocarbon impacts on the groundwater had 'significantly reduced'. This report concluded that while hydrocarbon impacts still exist 'the site is not considered to present a significant risk to human health, with the proviso that no on-site groundwater be used for domestic purposes'. Eight large underground storage tanks (containing approximately 100,000 litres) were removed from the site in 2003. Greater Wellington does not hold a copy of a tank pull report and therefore that no contamination has occurred cannot be verified.
2014: Information was received (dated 18 November 2013) from Mobil including several reports from PDP Ltd on environmental site assessment and groundwater monitoring. Mobil requested the letter and report remain confidential.

Landfill, Ngaumutawa Rd
PT LOT 141 DEEDS PLAN 163 BLK IV TIFFIN S D
Although little information is available it is suspected a closed landfill is present onsite. It is understood that the site was developed at the end of the Second World War. Initially gravel was extracted at the site to a depth of approximately 3- 3.5 metres. The void created was then backfilled with general refuse and cleanfill. Eyewitnesses have stated that some small arms ammunition was present within the fill materials. Given the age of the site it is considered unlikely that any significant leachate or landfill gas is being generated. However, the extent and nature of any potential contaminants on the site is unknown.
It is recommended that prior to any development of the site that intrusive investigations are undertaken across the site to determine the extent and depth of any fill materials. Analysis of these materials is also recommended to determine what, if any, contaminants are present.

Wood treatment or preservation including the commercial use of anti-sapstain chemicals during milling, or bulk storage of treated timber outside, Storage tanks or drums for fuel, chemicals or liquid waste
HEREWINI ST
This site has been used as a works depot and for timber treatment. As a works depot bitumen was stored in an aboveground and underground storage tank. In 2003 there was a dangerous goods licence for class 3 hazardous substances (4,500 litres). Two large underground storage tanks are thought to have been removed in 1999 however Greater Wellington does not hold a removal report and therefore that contamination has not occurred cannot be verified. A note on file states that a 200 litre fuel tank has leaked onto the ground - it is unknown if this was contained or the contaminated soil removed. The date of the spill is unknown. Although the site has been well bunded (for the timber treatment operation) no detailed site investigation is held by Greater Wellington and therefore the extent of contamination as a result of the works depot, if any, is unknown.

Conwood Investments Ltd
This site has been used for the treatment and storage of CCA (copper, chromium, arsenic) timber by Treeline Timber Ltd. Soil sampling by Greater Wellington in 1998 identified concentrations of arsenic, chromium and copper, above background levels, although only one sample was analysed, and levels were below acceptance criteria for industrial unpaved in accordance to the Timber Treatment Guidelines (MfE, 1997).
In 2003, CCA sludge mixed with sawdust was placed on a site immediately to the west (co-ordinates 2729560, 6023916), which at the time was leased by Treeline Timber. Greater Wellington issued an abatement notice, which resulted in this specific area being remediated (Glasson Potts, 2003).
A PDP report (1999) investigated CCA and PCP in off-site surface water, sediments and groundwater. Analysis of sediment samples showed copper, chromium, and arsenic concentrations above background concentrations. Groundwater samples from a bore (reference bore 81/5.3/D) contained high levels of arsenic. It is noted that a substantial spill of CCA concentrate occurred on an adjacent site occupied by Carter Holt Harvey Ltd.
In March 2021 a Detailed Site Investigation (DSI) was undertaken by Geo & Hydro K8 Ltd. Sampling included 26 soil samples from a grid, which were analysed for heavy metals, and 10 groundwater samples in total from 5 monitoring wells. Arsenic above commercial levels was identified in the soil of the south-east corner, where the former treatment plant resided. It was concluded that groundwater was not contaminated. Subsequently, a Remediation Action Plan & Contaminated Site Management Plan was prepared by Geo & Hydro K8 Ltd in September 2021. A total of 250 tonnes of arsenic impacted material was excavated from the SE portion of the site and disposed of at Silverstream Landfill. 4Sight have completed validation of the soils remaining in-situ, with concentrations of all CoPC below the respective adopted human health assessment criteria for the proposed commercia/industrial redevelopment of the site (The driveway was not tested).
The SVR has been written and reviewed by a Suitably Qualified and Experienced Practitioner (SQEP) in accordance with the requirements of the NESCS.

This site has, until recently, been occupied by a waste oil collection business and was formerly part of the former Shell oil refining plant. See file SN/03/046/02. The part of the site associated with the oil plant ceased operations in 1988 and was decommissioned in 1995. A Shell Oil report in 2000 noted that this site was primarily vacant ground used for ad-hoc storage as required and not significantly impacted by soil contamination. One area of the site has been used to store agricultural chemicals. A Greater Wellington Regional Council Take Charge Assessment in 2002 found waste oil had been spilt at a number of locations on the site and that the integrity of the bund tank was poor.

This Seaview site has operated as a bulk storage facility and manufacturing/blending plant of oil based and chemical based products, since the 1950's. A number of chemicals have exceeded relevant guideline values for an industrial site, for further information of these exceedances see OurSpace file SN-03-174-02. A 1997 Risk Assessment Report identified a number of soil and groundwater contaminants which were present of the use of the property for petroleum and chemical manufacturing and storage over the past forty years.
Further contaminated material including significant quantities of hydrocarbon contaminated soil was removed in 2002. A risk of potential groundwater contamination, by hydrocarbons, was identified. A hydraulic containment system was operational in 2003, shallow groundwater is abstracted to maintain a hydraulic gradient towards the centre of the Shell site which is then treated and then discharged to the storm-water system. Storm-water quality monitoring indicates that the site is complying with the conditions of discharge.

PTS DP 6253 - MEMORIAL PARK -
The Wellington Region Munitions Site Histories Munitions Report (Opus, 2000), verifies the site was used as a rest camp for United States servicemen between February and October, 1943. It was thought unlikely that large amounts of ammunition would be present at the camps considering their purpose and the distance the camps were from the port. Any rubbish which may be buried around the camp, would include general camp waste, heavy metals, petroleum hydrocarbons and possibly some small arms ammunition. It is unlikely the site contains significant quantities of waste given the other recognised dump sites in the area. There is however potential for the ground to have small pockets of heavy metal contaminants.
2023-Masterton Centennial Women’s Bowling Club was open at least from 1938 but has now closed. Exact historical records of the lawns opening are not available. The club rooms are now used for a Rugby Football Union headquarters, and the natural green still exist. Sports turfs are often very intensively managed to control weeds, insect pests and fungal diseases. Historically DDT, dieldrin and arsenic- based pesticides were used to control insects in turf until the last remaining arsenic based herbicide (methylarsenic acid MSMA) was deregistered in 2010. While the use of DDT to control grass grub in pasture was banned in 1970, DDT could still be used under permit to control grass grub in playing fields and bowling greens. Pentachlorophenol was used on turf to control moss and Endosulfan was used to kill earthworms in sports turf, which was permitted for use in New Zealand until 2008. A range of mercury-based fungicides were also available in New Zealand and are likely to have been used to control fungal diseases in turf. Evidence of the HAIL activity was verified by reviewing historical images, NZ archives and the club’s website. Greater Wellington holds no further information

These tanks were to be removed in 1996 however Greater Wellington does not hold a tank pull report to verify this. A Royds site investigation was undertaken in 1995. This report identified low levels of hydrocarbons in the surface soils thought to be as a result of surface spilling and leaks. The area was to be sealed as a carpark.

Ex Transport Wairarapa Ltd
2007: This site has been used by Transport Wairarapa, Wairarapa Bulk Fertilizers and as a Mobil Depot. There have been on site eight above ground storage tanks containing large quantities of petrol and diesel hydrocarbons (100,000 litres each). It is not known if these tanks remain as no tank pull report is held by Greater Wellington. Anecdotal information from an old employee states that excess wastes (oils and sludge) was disposed of down a hole at the back of the property. Groundwater monitoring has been undertaken by PDP in 2001. This monitoring identified petroleum hydrocarbons in the groundwater beneath the site. It was thought likely that petroleum in the groundwater may move off site into neighbouring properties (2001). The Regional Council called for further investigation to determine the extent and degree of contamination but it is unknown if this has been undertaken.
2014: Information was received (dated 18 November 2013) from Mobil including several reports from PDP Ltd on environmental site assessment and groundwater monitoring. Mobil requested the letter and report remain confidential.

Bulk hydrocarbons have been stored in an underground tank on the site. It is understood that the tank was removed from site in 2001, however, Greater Wellington has not been provided with a tank pull report and therefore no record of the tanks removal or any residual contamination.
2023-Three underground storage tanks were removed from Proposed Lot 1 of the subdivision by Masterton Trust Lands Trust (MTLT). Greater Wellington was not provided with a PSI or DSI for the removal of these tanks-there is still potential for contamination. MDC suggested that they may have been from the plastics factory. Greater Wellington has also identified that proposed Lot 2 (currently vacant) had a gas station on site in the 1940’s called Tatton Bro’s Ltd, where four petrol pumps existed. The SLUR polygon was amended to include the location of Tatton Bro’s. No further information is available.

This site was used for gasworks reticulation. Photographs on file show that the Gasworks existed on this site in 1922, however the start year is unknown. A gas holder was located near the rear of the site. As it was not used for manufacture wastes were limited to the tar accumulation normal at the site governor, contaminated water and tar accumulation in the gasholder base and other metals (possibly lead) associated with the use of the site as a works yard. Monoethylene glycol was known to be stored on site. Waste disposal practices are unknown. Once the gasholder was removed (1971) the site was filled with rubble, including thousands of gas meters. From 1982 the site buildings were slowly demolished and new buildings were built. With the exception of some soft material near the front of the site, no material was removed from the site.
A Wellington Regional Council 'Gasworks History Investigation' found that as the site is covered in buildings or pavement the risk to the site occupants are negligible. It is recommended that further investigation be undertaken for any future site development. The risk to the marine environment was considered low. It is unclear as to whether this assessment included the fill material used.
There is currently an underground storage tank on site (2003).

QUEENS DR
2007: From the turn of the century this site was used as a quarry which included facilities for paving and maintaining roads. Later the site was used as a landfill and operated as a tin tip from 1931-1936. A paving plant was established at this site in 1957. In the late 1980's Maranui was abandoned as a Council Works Depot and the paving plant was demolished. By 1995, all bitumen storage tanks and kettles were removed. In February 1996 four underground storage tanks were removed. Test results indicated elevated levels of petroleum hydrocarbons, with both diesel and kerosene present. Asbestos was also observed in refuse exposed in the soil excavations. In late 1996, the entire site was covered in greywacke fill. The fill material used, while not thought to be contaminated, was poorly compacted.
A site investigation in 1999 by Montgomery Watson identified elevated levels of metals. Shallow soil samples generally complied with contaminated sites guidelines, but there were elevated levels of heavy metals detected deeper in the landfill. Copper, lead and zinc in particular exceeded guideline levels. There was no obvious petroleum hydrocarbon contamination however potential hydrocarbon contamination from underground storage tanks was not fully resolved due to the depth of cover.
Depending on the use of the site it was thought likely that some form of remediation or management will be necessary to reduce the risks to future site users.
A Wellington City Council septic tank is known to have been on this site. No further information is held by Greater Wellington and it is unclear if it remains.

Clean Fill Site
HUTT RD
PT SEC 1 SO 36654 - SUBJ TO ESMT ON DP 88158
The site has operated as a clean fill and approximately 16,000 m3 was deposited on the site this predominantly between 1991 and 1993. Materials deposited at the site include vegetation, demolition material (including steel), pipes, concrete blocks and pavers and road paving (asphalt).
A limited site investigation undertaken in 1998 found that the poly aromatic hydrocarbons were consistently elevated above guideline values for residential use across the site. Metal concentrations were elevated but complied with relevant guideline criteria. Results indicated that long term exposure to soil at the site posed a potential health risk from ingestion of contaminated soils or produce grown in those soils. It was recommended that this be managed by putting a 0.5m cap in the area of the house and potential vegetable garden. The remainder of the site would be covered by a layer of clean soil. Greater Wellington has no record of any capping materials being placed on the site. A management plan to identify risks and procedures to avoid contamination was prepared - Greater Wellington only hold a draft copy of this plan - and a residential property was built on the site (1999).
Further filling was undertaken in 1999/2000. Material to be dumped for this was 85% hard-fill, 10% concrete and 5% asphalt. It is not known if this material has been capped or where the filling occurred.

This site has been used for the storage of oil and aviation fuel. Two underground and one above ground tank are on site. A spill occurred in 1994. If contamination occurred or if it was remediated is unknown. A small spill also occurred in 1998 and was discharged to the harbour. Two underground storage tanks were removed in 1998. A high level of contamination was found in the pits and contaminated soil removed. Sampling indicated that the residual petroleum hydrocarbon concentrations in soils at the site were shown to be well below the Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand (Draft 1997). (See also Site No SN/05/111/02).
GHD 2021 - Wellington International Airport Detailed Site Investigation identified the JUHI (Joint User Hydrant Interface) which contains six bunded above ground tanks and is operated by Exxon Mobil. Historically, the JUHI was the location of the Hertz rental car site. Groundwater samples from four monitoring wells were analysed for total hydrocarbons and heavy metals. The results are not presented within the report. However, separate phase hydrocarbons were not observed in any of the wells and contaminant concentrations were below applicable criteria. The site is capped but it is likely that contaminant concentrations are above human health criteria in areas of ongoing use (JUHI) and along the airport fuel line running west of the airport terminal. As such, there is a risk of workers coming into contact with hydrocarbon impacted soils when undertaking soil disturbance work in these areas.

Ex Melrose Rd / Albert St landfill
FOYLE ST
The land between Melrose Road, Albert Street and Foyle Street was used as a landfill in the early 1930's. Filling at the site was undertaken as part of road improvements. In 1948 refuse and spoil encroached into the watercourse, which was not piped under the landfill. Run-off flowed under the refuse at the toe of the tip face. The landfill was possibly a tin tip - i.e. provided a place for trade rubbish and debris that could not be burnt. Greater Wellington Regional Council does not hold any records detailing the nature of the fill materials.
Any leachate from the site is likely to discharge into the stormwater system or into groundwater. The site is considered relatively low priority with respect to the discharge of leachate. Based on the size, age and type of refuse disposed, the potential landfill gas generation has been estimated as low. The surrounding residential properties have the potential to act as gas collection points. This site is considered relatively low priority with respect to the discharge of landfill gas. No sampling has been undertaken by Greater Wellington Regional Council (Filed 2003).

There were several underground and aboveground storage tanks on the site which were used for storing raw materials such as toluene, xylene and other solvents. On residential development the site was to be covered with fill. The nature of the fill material is unknown. There is no information regarding the removal of the tanks from the site or any validation testing held by Greater Wellington.

Former BP Express Miramar
Service stations including retail or commercial refuelling facilities, Storage tanks or drums for fuel, chemicals or liquid waste
MIRAMAR AVE
This site is currently a service station and previously part of a tank farm that was originally used for storage of diesel and bunker oil petroleum product to service shipping at the Miramar Wharf. Between the 1920s and the 1960s five above ground storage tanks were on site. When the site was vacated all but one tank was removed. This last tank was removed in the 1970's. There were five underground storage tanks on site and an LPG tank as part of the service station operation.
Information received (URS report, 2009) shows that the underground petroleum storage system (UPSS) consisting of five underground storage tanks (USTs) were removed. Nearly 115 tonnes of hydrocarbon impacted backfill, mainly from the tank pits, was also removed from the site. A number of soil samples were collected from natural ground remaining at the site. Hydrocarbon impact was recorded in soil samples at the level of the water table in all tank pits, beneath dispensers and remote fills (maximum TPH of 39,000 mg/kg). Analytical results associated with soils collected at the groundwater table (1.5 m bgl) were found to exceed the Tier 1 acceptance to maintenance/excavation workers and volatilisation to indoor air.
Information received (URS report 2009/10) shows that a phase II investigation has been undertaken and a contamination management plan (CMP) has been prepared. As part of the phase II six monitoring wells were installed, followed by three separate groundwater monitoring events. Results indicate that lateral migration of contaminants in shallow groundwater from the former UPSS is occurring, however it appears that the concentrations of hydrocarbons decrease rapidly with distance from residual source area. The investigation results indicate a potential risk to maintenance/excavation workers undertaking below-ground works in the areas of the former UPSS. The CMP provides a framework for the control of below-ground works during the re-development. It is understood the site is to be re-developed into a petrol handling facility with two USTs to be installed. Due to the CMP the site is considered managed for its commercial/industrial land use.
September 2012: AECOM was engaged by BP Oil New Zealand Limited to undertake additional environmental investigations at the former BP Miramar Service Station, 29 Miramar Avenue, Miramar. AECOM supplied GW with a copy of the report GW ref. # 1125073. Results of TPH and BTEX (in soil and groundwater) and volatile compounds and TPH (soil vapour) are reported.. The report concludes that residual petroleum hydrocarbon contamination is present in soil and groundwater in the vicinity and down-gradient of the former underground petroleum storage system (UPSS). The report states there is a well defined plume of dissolved phase hydrocarbons in the groundwater beneath the site. The report infers that this dissolved phase hydrocarbon plume has developed in response to the presence of petroleum hydrocarbon impacted soils located on-site, potentially derived during the former use of the service station UPSS.
Assessment of the data in relation to Tier 1 acceptance criteria from the Oil Industry Guidelines (MfE, 2011) indicates that concentrations of dissolved phase hydrocarbons in groundwater down-gradient of the former UPSS could potentially pose a risk to human health via volatilisation to indoor air for occupiers of the off-site commercial properties located along the east boundary of the site, but results of soil vapour testing suggest that this is highly unlikely. The report concludes that a minor off-site discharge of dissolved phase hydrocarbons is occurring along the south and likely along the south-eastern boundary of the site; however the analytical results from the two off-site monitoring wells indicates it is unlikely that a risk will be posed to human health off-site.

A diesel spill to the Kaiwharawhara Stream occurred in 1993. No detailed site investigations are held on file, however excavated soil was sampled on removal for site modifications in 2005. The samples were analysed and found to be below Ministry for the Environment Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand (1999). It is unclear if contamination has occurred on other parts of the site.

This site has been used as a tannery and also for oil storage. The tanning pits used lime and tanning bark solution. A site investigation undertaken in 1990 found contaminated soil was 1-3m below the surface and increased towards the south end of the site. Bore monitoring found high levels of total petroleum hydrocarbons. It was thought likely that the product in the ground had leaked from the tank farm to the north, although it is unclear which one (See Site No 05/068/02 and 05/070/02). Greater Wellington's records show a remediation scheme was proposed for the site and all significantly contaminated soil was to be removed. Greater Wellington does not hold any evidence that the scheme was undertaken and no records of any validation testing.

This site was previously a flour mill and is now used as an oil depot. The site was subdivided in 1998. It is thought that lot 1 was not used for the storage of petrol. In 1998 lot 1 was used for the storage and maintenance of mobile cranes. Monitoring of a neighbouring site (see SN 05/069/02) found elevated levels of hydrocarbon contamination which may have originated from this site. No detailed site investigation is held by Greater Wellington for this site and therefore the extent of contamination is unknown.

This site is a service station. A hydrocarbon spill occurred in 1992 (approximately 5000 litres), some contaminated soil was excavated and the tanks removed and replaced. The site was redeveloped in July 1997. Soil sampling undertaken found low levels of contamination. The tanks were replaced with double skinned fibreglass tanks and double skinned pipe-work. There are currently three underground storage tanks (containing petroleum hydrocarbons) on site (2004).
Information received (URS 2009) shows that the underground petroleum storage system containing three underground storage tanks (USTs) has been removed from the site. Analysis of soil samples taken at the time of the UST removals show that all samples representing soil remaining on site comply with relevant guidelines for an industrial/commercial land use.

This site is a service station with the bulk storage of hydrocarbons. Solvents (kerosene based) are known to have moved from the site and onto the neighbouring residential property. It was thought that the solvent was related to an earlier use of the site (spray painting).
Monitoring concluded that the product found at the boundary of the residential property was petrol based. It is therefore thought that petrol-based free and residual product occurs below ground from the location of the underground storage tanks to at least the southern boundary. Petroleum related hydrocarbons were also detected in the groundwater at elevated levels. The source of the product has been removed. A waste oil tank was removed in 1994 and six underground storage tanks were replaced in 1996. It is unclear the extent of the contaminated soil that remains.

In the late 1960's the site was reclaimed from the sea, no information is held which details the nature of the fill materials. A waste incinerator was constructed on the site in the early 1970's. Initially the incinerator was fuelled with diesel from an underground fuel tank located on the site. However, in 1989 the incinerator was converted to be fired by reticulated gas. The incinerator was used to dispose of medical and quarantine waste including pathological, veterinary, pharmaceutical and domestic type wastes. These wastes comprised plastics, metals, paper, dressings, food and packaging.
An investigation into the shallow soils on the site was undertaken in 2001, which identified areas of elevated metal contamination. A soil sample was also taken for dioxin testing, whilst the analysis showed dioxins to be present they were below the residential health guideline values. Where contamination on the site exceeded human health guidelines for residential use, remediation of the site was undertaken. The remediation involved the removal of the contaminated materials to landfill and the decommissioning of an underground fuel storage tank. Following the remediation a validation exercise was undertaken, which showed the concentration of contaminants remaining on the site did not exceed human health criteria for any land use.
However, concentrations of some contaminants in the shallow soils exceeded environmental guidelines and no investigation has been undertaken to determine the nature of fill materials used to reclaim the site.

Southgate Reserve (ex Melrose landfill)
HUDSON ST
This site was previously a landfill for both commercial and domestic waste. The release of high levels of methane in 1995 forced the evacuation of three homes. Six test bores were drilled to assess the gas levels. The methane levels at four locations exceeded the guideline levels in place for both the UK and USA. A report in 1994 noted that it is likely that landfill gas will continue to pose a risk to nearby houses for many years. It was suggested that properties be monitored regularly for landfill gas both onsite and off to assess potential migration. There is no information regarding ongoing monitoring on the SLUR file.
Information received (URS, 2006) shows that a soil contamination and leachate characterisation project was undertaken at the site. The surface of the park appeared to be in good condition. Analytical results from the soil samples taken from the landfill cap were found to contain TPH concentrations below detection limit, and heavy metal concentrations similar to background levels. Landfill waste was found in all three boreholes at the park. Waste appeared to be mostly household waste. Analytical results from waste samples were found to contain high TPH concentrations, and high concentrations of lead and zinc. The presence of leachate was also confirmed in a monitoring well. Analysis showed that the leachate contained high levels of ammoniacal nitrogen, boron, chromium, lead and zinc, which all exceeded guideline values.

This site has been used as an Air-Force base. General military camp facilities including workshops, paint stores, munitions stores, sewage pumping station, a rifle range and a shipway and repair yard were onsite. An underground storage tank was also on site but has since been removed. No tank pull report is held by Greater Wellington. There are unconfirmed notes on file suggesting a landfill on this site, but there is no indication of a location or likely contents if it exists. The site was decommissioned in 1995. Potential contaminants include explosives, lead, copper, antimony, solvents and metals and hydrocarbons. No detailed information is held for this site regarding the level of contamination, if any, that has occurred.

This site was used in the production of rubber products from the 1920s and a battery recycler (removal of lead) operated from the 1940s and 1950s. In the early 1970s the manufacture of detergents, alcohols and oils was undertaken. There is also evidence that a dye packing room was located on the land for a period of time. Soil sampling undertaken for a preliminary site investigation for total petroleum hydrocarbons and metals showed that the levels of these contaminants were below the relevant criteria for commercial and industrial activities and for the protection of maintenance worker's health. Measures will, however, need to be taken to control any potential discharge of contaminants in the future should any excavation be required.

This site has been used as the Wellington City Council depot with engine works undertaken and a large number of underground storage tanks of hydrocarbons on site. The lot also housed the council stables and a concrete storage and timber yard. Between 1888 and the 1930s an incinerator was also on the site.
An assessment in 1997 noted that elevated levels of lead were detected in the soil. Hydrocarbons were also detected but were low enough to pose no significant health risks. The majority of contaminated material was removed and a capping layer of clean-fill was placed over the remaining material (2003). Groundwater monitoring undertaken in 2003 found that while the concentrations of a number of contaminants exceeded the highest water quality standards available, in groundwater monitoring wells, at the site of discharge levels of contaminants would be attenuated and diluted to a level where the contaminants could be considered insignificant against appropriate standards. Construction of the park and recreation area was undertaken in 2005/2006.

This site manufactured zinc oxide by smelting approximately 100 tonnes per annum of copper based non ferrous oxide. An underground storage tank is on site. Approximately 20 tonnes per annum of electrical cables were also burnt to recover copper. When the cables were burnt the lead coating contaminated the ground.
A site visit by Greater Wellington in 1997 found obvious lead contamination in the area where the cables were burnt. Various metals and other scrap were stored throughout the yard, including a small quantity of batteries. The site appears to have been sold but it is unknown if the business remains. No site investigation is held by Greater Wellington and therefore it is unknown the extent of contamination that has occurred.

This site has been used for electroplating. A nickel, copper and chrome electroplating plant was installed in approximately 1993. This business was of a small scale. The operation would have used various chemicals, degreasing solvents and acids as well as producing metal particles and dust. An above ground storage tank (10,000 litres) for caustic soda is within the building. The tank is bunded and maintained at no more than half full. A site investigation undertaken in 2003 for a property development on this site found no evidence of contamination in the location of the proposed extension. Several businesses which occupy the site hold test certificates to store hazardous substances.

Wgtn Airport (Ex Gravure Plating Ltd)
TIRANGI RD
The building on this site was built as an aircraft maintenance facility which included an electro-plating facility and foundry. The electro-plating shop was used continuously until February 1995. The building was demolished in 1996 and was then sealed to be used for parking and/or the airport as an apron. At the time of demolition Health Environments Ltd inspected that site and revealed that significant amounts of heavy metal and cyanide residues were present. Some contaminated material was removed from the site.
A follow up site risk assessment (Dec 1996) found significantly high concentrations of Cadmium, Chromium Copper, Lead, Nickel and Tin particularly within the top 10cm of soil but also at lower levels at 40cm (Australian Guidelines for the Assessment and Management of Contaminated Sites 1991). These samples were highest around the area of the floor tank. It was considered unknown if these traces entered the soil by seepage or by being washed off the rubble after the floor slab was broken up by the contractor. Samples were not taken across the entire site. This site was compacted and sealed. This risk assessment was not independent and was undertaken by Wellington International Airport.
The site is classified as confirmed contaminated. See also SN/05/111/02 and SN 05/492/02.

This site was previously a large landfill in which general refuse including rubber and old fuel tanks was dumped. The Greater Wellington Regional Councils Investigation into 'Landfills in the Wellington Region' (1998) classified the site as medium priority with regard to the discharge of leachate. There was a visible discharge of leachate to the storm-water which flowed to Island Bay. Samples taken indicated that elevated levels of pH, iron, manganese, sodium, chromium, copper, lead and zinc exceeded the ANZECC Aquatic Ecosystems Guidelines.
Based on the age, size and nature of the refuse the potential gas generation for this site was also estimated as medium. There are nearby recreational and residential buildings which are potential gas collection points. A Gas Monitoring Report undertaken in 2002 noted that while gas concentrations in the wells were low they indicate ongoing gas production from organic residues in the fill and installation of a further gas vent 'would be a prudent measure'. Three gas wells were installed at the park in August 2002. Gas vents were also installed at two of the wells.
Information received (MWH, 2005) shows that a soil contamination and leachate characterisation assessment was undertaken at the site. No significant soil contamination was identified in the cover material, with heavy metal and total petroleum hydrocarbon levels all below guideline values. Landfill waste was found in a clay/silt matrix at a depth of between 3-4m. The fill varies in thickness across the site from about 9m to 14m. No leachate was found in the monitoring well, so no leachate characteristics could be determined. However, the probability of leachate being present is thought to be high given the high conductivity and presence of contaminated fill.

TAUHINU RD
This site has been used for vehicle maintenance with underground fuel tanks to supply the owners fleet vehicles and prior to that the bulk storage of fuels. An investigation in 2004 confirmed that the site has elevated concentrations of petroleum hydrocarbons in the soil at a number of locations on the site. The two main areas of contamination are near the former location of the underground storage tank and the tank filling stand. Contamination was apparent both near-surface soil and at the water-table. The investigation found only relatively low levels of contamination over much of the site, but given the relatively wide spacing of the investigation test pits and bore holes, greater contamination may exist at undetected locations. The site would be considered suitable for industrial/commercial use provided the site is paved or covered in buildings.
Follow-up groundwater monitoring results from 2006 show that sampled wells contained detectable concentrations of hydrocarbon residues. However, all results complied with the (MfE) criteria for outdoor and indoor inhalation for commercial/industrial and residential land uses. A site management plan has been developed to protect future occupants and maintenance workers from exposure to soil (2005).

PARK RD
This site has been used in the bulk storage of fuels (1923-1965) and in the manufacture of chemicals (1968 -1998). In October 1998 an environmental site assessment for Peterson Chemicals Ltd found that low to non-detectable levels of soil and groundwater contamination are present beneath the former chemical manufacturing areas and around the former dangerous goods area. Low levels of residual contamination occurs in soil over some parts of the site as a result of past use for bulk storage, however no remedial works were thought required to make the site suitable of commercial use. Underground and above ground storage tanks were removed from the site in 1998. Although the site is suitable for commercial and industrial use, further investigation will be required if the site was to change to a more sensitive landuse (e.g. residential).
An application for resource consent was received in 2002 to develop the site for a film post-production facility. A range of chemicals are used in film processing. However these are generally of lower quantity and toxicity than the previous sites use. Larger levels (1000 kg or less) of dry chemicals stored include sodium sulphate, sodium carbonate and ammonium thiosulphite as well as 800 litres of dissolvene.

This site has been used for chemical manufacture of synthetic resins. Raw materials used were alkyds, diesel, toluene, turpentine, white spirits, xylol, monomers, kymene, styrene, propylene glycol and emulsion. Potential contaminants include inorganic contaminants, volatile organic compounds, semi volatile organic compounds and hydrocarbons. Hatricks had many spills which have flowed through to the Porirua stream since it began operating in the 1950s.
Woodward Clyde has carried out an assessment and remediation program including a risk assessment that suggested that no significant risk was posed for either industrial or residential use in the absence of groundwater abstraction. It was considered possible that there other residual issues that have not been identified in the investigations to date, however these were dealt with by the preparation and implementation of an environmental site management plan. The site is now classified as a 'remediated site' suitable for residential use on the database and is now a retirement village (1998).

This site was previously a saw mill. There are very few details on this site. It is known that the mill had a limited timber production and used creosote treatment (containing hydrocarbons). It was noted that the operation was very low tech and possibly involved either the brushing of fence posts with creosote or a dip tank. Timber is likely to have been sourced from the adjacent Karori Reservoir area. There was no evidence of any remnant of the operation during a site visit in 1998. However there was a small dump containing metal scrap and old car parts on site, it is unknown if this has been removed (Wellington Regional Council Timber Treatment Sites Review). Part of the site now forms the Karori Wildlife Sanctuary.

Former Cottles Tip
HOROKIWI RD
This site was used as a landfill from the early 1960's to the 1980's. Initially the tip took solid waste but in the early 1970's it accepted most material including timber, bricks and masonry, car bodies and tyres, glass, large appliances, drums of hazardous waste, iron sheeting and plastics, meat wastes . There were a number of fires at the site to remove coated or sheathed cable over copper. Notes on file indicate that the landfill was not well managed and the landfill accepted industrial waste not suitable for disposal elsewhere in Wellington.
Sampling undertaken of the site by Greater Wellington found that average levels of zinc exceeded aquatic ecosystem levels. Lead levels and suspended solid levels below the tip face were also exceeded for both aquatic ecosystems and stock watering guidelines (1996-1997). In 2001 concern was raised about the possibility organochlorines and other herbicides/pesticides being dumped at the site. Results indicated that Semi Volatile Organic Compounds (SVOCs were not detected). In 2002 further testing was undertaken for polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzo-p-dioxins (PCDDs).

Soil sampling found results were within the applicable Tier 1 Soil Acceptance Criteria for both residential and commercial site use. It is noted that two remaining tanks on the site were unable to be removed safely, and were filled with concrete. One of these tanks contained waste oil. If buildings are removed from this site and a change in land use to residential is proposed, it will be necessary to re-assess contamination from the remaining waste oil tank. The site has been classified as a remediated site.

The site is an operational service station and motor vehicle workshop. An environmental site investigation undertaken by URS in 2004 found that although there was some residual contamination in the soils and groundwater beneath the site, it was at concentrations below the Ministry for the Environments 'Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand' (1999) for commercial and industrial land use.

Permacrib Retaining Walls Ltd
JEAN BATTEN ST
This site is used as a CCA (copper chrome treated arsenic) timber treatment plant. A site visit in 1998 found the site was well operated and there was no evidence of any contamination at the time. However there is potential for contamination (leakage from sumps or pipe work) which could only be detected by subsurface investigations. The CCA pressure vessel was under cover in the current building. The tracks were set in concrete and were also under cover. Drips from the treated timber were collected on the concrete bund and recycled back into the make-up solutions. The timber was then stored outside on a sealed yard. Greater Wellington holds no further details as to and detailed investigation for this site.

The site was established in the early 1940's as a timber treatment plant and engineering works. Timber treatment and engineering continued on the site until 1987 when the plant was demolished. In 1988 the construction of the Tawa Junction Shopping centre commenced. Greater Wellington was informed that prior to the complex being built, the whole site was excavated and unsuitable fill removed (including soft bog and sawdust deposits). The site was then filled to design levels with imported hardfill.
Greater Wellington holds no records detailing the excavation that took place or of any environmental investigations undertaken on the site. Potential contaminants associated with the timber treatment include chromated copper arsenate (CCA) and possibly pentachlorophenol (PCP). Activities associated with the engineering workshop include anecdotal evidence of an underground storage tank, use of solvents and fuel spillages.
A copy of a land use consent was received for the establishment and operation of a retirement complex on the site. The AEE found elevated arsenic and PAHs at one location. Greater Wellington has no record of any detailed phase two investigation or consequent Remediation Action Plan (RAP).

Prestons Gully Landfill
MURCHISON ST
This site was a landfill which accepted primarily domestic waste from 1973-1977. Small quantities of potentially hazardous domestic and industrial wastes may have been disposed of at the site. The landfill received approximately 1.0 million cubic metres of refuse during its lifetime with a max depth of 42 metres. The Tawatawa Ridge conservation area is to the north of the site. There does not appear to be any direct discharge to the Owhiro stream, however there is discharge to the sewer.
Information received (URS report, April 2007) shows that a Phase 2 site investigation was undertaken at the site. The investigation found the landfill cap to be in good condition with an approximate thickness of 0.3-0.5m. Analytical results from soil samples showed that Total Petroleum Hydrocarbon (TPH) concentrations were at or just above detection limits, and trace element concentrations were considered to be typical of background levels. A monitoring borehole is situated at the southern (down hydraulic gradient) end of the landfill. Elevated levels of metals in a sample from the well indicate the presence of leachate.

The site has been used by Taubmans (New Zealand) Ltd and Cortaulds Coatings (New Zealand) Ltd for the production of paint and varnishes. Lead/chromium paint, mercury anti-fouling paints and acrylic and polyester varnishes were produced at the site. Large volumes of solvent were stored on the site in aboveground and underground storage tanks. A number of spills had occurred at the site before the site remediation undertaken in 1997/98.
The groundwater beneath the site remains contaminated with hydrocarbons from the site and the old gasworks located to the west of the site. The risks posed to site occupants have been mitigated by the removal of the BTEX contaminated soils combined with the sealing of the surface.

Sinclair Park
HOUGHTON BAY RD
This landfill has operated in two phases. The first filling operation was from 1950-1963, in the lower reaches of the valley, and now forms the playing fields up to Houghton Valley School. Most of this fill is gas works material with moderate concentrations of wood, metal, plastic and newspaper also present. The second land filling phase formed the playing fields and reserve from the Light House Grounds up to Sinclair Park and operated between 1963 and 1971. Investigations suggest that the fill was similar to the earlier fill, but had a greater domestic content.
There is an effluent pipeline that was designed to intercept the main Houghton Bay storm-water drain. It takes the dry weather flow westward to a discharge point into the existing sewer line. Heavy rain results in leachate overflowing into the storm-water system and onto the beach. Based on visual and olfactory observations at the Houghton Bay Beach, it appears that there is an additional leachate discharge to storm-water.
The site is considered high priority with respect to the discharge of leachate. Sampling has indicated elevated levels of iron, manganese, chromium, lead, nickel and zinc which exceeded the ANZECC Aquatic Ecosystems guidelines levels ('Landfills in the Wellington Region' Wellington Regional Council Technical Report 1998).
This site is also considered high priority with respect to the discharge of gas. The Wellington City Council was according to our file records 'addressing these issues' in 1998.
Information received (URS report, March 2007) shows that a phase 2 investigation involving a soil, waste and leachate characterisation was undertaken on the site. Generally, the surface of the park appeared to be in good condition, although it was found to be as thin as 0.25m at the southern end. Analysis of soil samples taken from the landfill cap showed low concentrations of total petroleum hydrocarbons (TPHs), and heavy metals. Leachate samples taken from four monitoring wells were also analysed. The analytical results confirm the presence of leachate. Comparisons with guideline values indicate that all the leachate samples exceed trigger values.

BURMA RD
SECS 211 368 369 PT SECS 6 217 218 324 PORIRUA DISTRICT - RAROA PARK -
This site has been used as a landfill with the total volume of waste around 344,000 cubic metres. The waste stream was mainly domestic but also included abattoir effluent. Monitoring of the Ngauranga Stream, below the Raroa landfill, was undertaken in 1993-1994 and showed that ammonia had reached chronic and acute toxicity levels and was toxic to aquatic life.
Wellington City Council reports recommended the installation of a passive venting system. Leachate control works were to be designed to divert storm-water flows and collecting seepage from the face of the fill (WCC 1997). A leachate collection system was put in place to divert leachate to the sewer, however it is believed that a proportion of leachate will continue to flow into the receiving environment. The current use of land is a sports field.
Information received (MWH, 2005) shows that a soil contamination and leachate characterisation assessment was undertaken at the site. The cap thickness was found to range from 2.2m to 4.0m across the site, and to be in good condition. Analysis of samples taken from the capping layer showed no evidence of soil contamination, with heavy metal and total petroleum hydrocarbon (TPH) concentrations reflecting background levels. A range of waste material was found to a depth of 22.5m, and a void under the cap during drilling of a borehole indicates that some waste may remain unconsolidated in places. Confirmation of leachate was obtained from a monitoring well on site. The leachate was found to contain high chromium, lead, zinc and ammonia.

2011: This site is part of a much larger lot that is or has been used for rail yards. It was reclaimed from the harbour between 1882 and 1932 using a variety of fill materials. Originally it was occupied by wharf facilities. Fuel (hydrocarbons) is thought to be stored in the rail yards, but the precise location is not known. Wellington Regional Council records show that 'a large quantity of heavy oil' was spilt from the yards in 1989, entering the harbour. Further contamination was identified in the transfer area of fuel near the aboveground storage tanks. A Wellington Regional Council Hazard Assessment in 1998 identified the site as one of high priority for further investigation. However in 2006 Greater Wellington held no detailed assessment or investigation for this site (See also file SN/05/402/02.
Information received (April, 2008) from Wellington City Council shows that a number of other incidents have occurred on the site involving chemical spills. Also there is a list of chemicals stored on site, and evidence to show there is an above ground storage tank containing diesel.
2013: A report was received (#1502440) regarding two soil samples taken from a soil stockpile and tested for heavy metals and TPH. Further details are in the report. No locations of sampling points were presented.
2019: Several reports were received (12070.01; 12051.02; 13662.01; 13662.11; 13662.08) in response to a resource consent (WGN200019) for a proposed TOLL depot along Aotea Quay.

The site was previously the Waingawa Freezing Works. As part of the freezing works operations, the bulk storage of hydrocarbons and mineral acids, and the treatment of hides, took place on site. Greater Wellington Regional Council is not aware on any environmental investigation having been undertaken. Therefore, it is recommended that prior to any redevelopment, a site investigation is undertaken to determine the nature and extent of any residual contamination. The site investigation should be undertaken in accordance with Contaminated Land Management Guidelines (Ministry for the Environment 2003/4).

Former Miramar Gasworks
SOUTHAMPTON RD
This site was previously part of the Miramar gasworks. The Wellington Gas Company purchased 14 acres of land in Miramar in 1907. In 1912, a gas holder with 1.5 million cubic feet capacity was erected along with a carbonising plant. In 1922 and 1926 a Glover-West Vertical System was erected along with a 2 million cubic feet capacity gas holder. In 1961 a third gas holder was erected to meet the needs of the Hutt Valley after the Petone gas works closed down. Coal gas was replaced by natural gas in 1972.
An investigation of the gasworks site in 1996 showed significant concentrations of contaminants to be present both in the soil and groundwater beneath the site. It was identified there was potential for offsite migration of contaminants via groundwater.
A further investigation undertaken in February/March 2005 showed that the contamination present does not pose a significant risk to the occupants of the site in it is current state. The site is covered by an impermeable barrier which prevents direct contact with the contaminants present on the site and minimises the risk of vapour migration into the building. The barrier also prevents ingress of water reducing the potential for offsite migration of the contaminants.
Should any site redevelopment/modification be proposed it will be necessary to ensure that these changes will not reduce or in any way diminish the protection provided to site users and the environment.

This site is currently used for Timber Products and Furniture. The site has operated as a timber and hardware yard since at least 1939. It is understood that this site was only operated as a timber/joinery yard throughout its history and that timber treatment chemicals have never been used. A site investigation in 1993 found that arsenic levels were well above recommended guidelines and that copper and chromium were also elevated. PCP was not detected. Site remediation undertaken in 1994 meant that the site substantially met the requirements of the Australian and New Zealand Guidelines for the Assessment and Management of Contaminated Sites. However, a small proportion of the remediation work was not able to be carried to conclusion because of site conditions (presence of a storm-water pipeline and need to avoid subsidence near a stream) and the condition of the site under the existing seal is largely unknown although samples taken indicate the contamination of the area is unlikely. The site is next door to a children's playground.

This site was previously used as a tannery and above ground oil tanks for this operation were on site in the late 1920's. It was used as a general storage yard in the early 1950's and in the early 1980's as a waste depot. Twenty one underground storage tanks were installed during this time mainly for waste oil, but also for detergents solvents and Jet A1 on occasions.
A site clean-up was undertaken in 1996 and soil samples taken following the removal of the tanks were below 1,000 mg/kg total petroleum hydrocarbons, except for three locations. It was thought likely that a limited amount of residual hydrocarbons and contaminated groundwater remained on site which had the potential to move offsite.
The site was capped with concrete and provided this cap is maintained, the residual contamination at this site was considered unlikely to have no on-going environmental effects.

Ex Miramar Tank Farm
MIRAMAR AVE
This site was originally used for storage of diesel and bunker oil petroleum product to service shipping at the Miramar Wharf. Between the 1920's and the 1960's five underground storage tanks were on site. When the site was vacated all but one tank was removed. This last tank was removed in the 1970's.
Remediation of the site was carried out in 1994 prior to the site being redeveloped for residential use and as a garden centre. Validation results for the residential subdivision provided to the Wellington Regional Council show that the levels of petroleum hydrocarbon product remaining on site are within the relevant guideline levels (Dutch Soil Clean-up Guidelines 1983). According to file notes not all the contaminated soil has been remediated outside of these areas. See Site Number SN/05/147/02.

This site is operating as a substation. A cable oil leak of 600 litres of mineral oil occurred in 1996. A large area of contaminated soil was removed. Subsequent soil sampling of material remaining in the tank pit found that TPH (total petroleum hydrocarbon) levels were within applicable Tier 1 Soil Acceptance Criteria for commercial/industrial land use (Ministry for the Environment "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand (Draft 1997). The site investigation undertaken by Royds Consulting (January 1997) indicated that a routine site assessment be undertaken prior to any future sale of the site to document the presence and nature of contaminants across the site as a whole.

This site was previously part of the Miramar gasworks which operated from 1907 - 1972. An investigation into the gasworks site undertaken in February/March 2005 showed that the contamination present does not pose a significant risk to the occupants of the site in it is current state. The site has also been used for electroforming and the chemicals used for this operation included trichloroethylene, ammonia and sulphuric acid.
Hydrocarbons have also been stored in bulk on this property. The 2004 Dangerous Goods Licence lists two aboveground storage tanks and four underground storage tanks on site. No further information is held by Greater Wellington and therefore the extent of contamination, if any, resulting from these tanks is unknown.

Former Cottles Landfill
HOROKIWI RD
LOT 2 DP 28139 BLK XIII BELMONT SD
This site was used as a landfill from the early 1960's to the 1980's. Initially the tip took solid waste but in the early 1970's it accepted most material including timber, bricks and masonry, car bodies and tyres, glass, large appliances, drums of hazardous waste, iron sheeting and plastics, meat wastes . There were a number of fires at the site to remove coated or sheathed cable over copper. Notes on file indicate that the landfill was not well managed and the landfill accepted industrial waste not suitable for disposal elsewhere in Wellington.
Sampling undertaken of the site by Greater Wellington found that average levels of zinc exceeded aquatic ecosystem levels. Lead levels and suspended solid levels below the tip face were also exceeded for both aquatic ecosystems and stock watering guidelines (1996-1997). In 2001 concern was raised about the possibility organochlorines and other herbicides/pesticides being dumped at the site. Results indicated that Semi Volatile Organic Compounds (SVOCs) were not detected. In 2002 further testing was undertaken for polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzo-p-dioxins (PCDDs).

LOT 6 DP 64470 LOT 1 DP 59984 PT LOT 91 DEEDS 108 SO 19625 SECS 1 3 SO 55120 6 - WILTON BUSH RESERVE
This site has been used as a landfill for both domestic and industrial waste and is currently used for sports fields. The volume of waste deposited at the landfill is approximately 1,720,000m3 and extends to a maximum depth of 42 metres. Other special wastes which were accepted at the site include sodium cyanide, spent oxide, gasworks material, waste oil and grease and acid coal tar. It also received contaminated furniture and planking after a radiation leak at Victoria University in the 1960's and testing of the leachate, with regard to radiation, was due to be undertaken in 2005. A significant amount of construction rubble was deposited in the southern corner of the site and from the 1970's abattoir effluent was also deposited.
Leachate is known to have seeped into the Otari branch of Kaiwharawhara stream (1990) although no sampling was undertaken. The landfill was capped with 1 metre of clay and overlain with topsoil. There is a school nearby and in 1995 gas traps were used to stop methane gas entering the school. It is understood further gas monitoring was undertaken in 1996. The Wellington Regional Council does not hold a copy of these results. The site is surrounded by a residential area.
Information received (URS report, March 2008) shows that a soil contamination and leachate characterisation investigation has been undertaken at the site. The cap thickness was found to range from 1.0m to 2.5m across the site, and to be in good condition. Low concentrations of metals and TPH were found in soil samples taken from the cap, but did not exceed guidelines. Confirmation of leachate was obtained from a monitoring well on site. The leachate was found to contain high boron, chromium, zinc and ammonia. More sampling is to be undertaken by WCC to determine whether leachate is being discharged off site.

Polhill Gully Landfill
HAPPY VALLEY RD
PT SECS 19 21 OWHIRO DIST
2007: This site was intended to be used as a cleanfill for demolition material, however, an inspection undertaken by the Wellington Regional Council in 1993 found that the landfill also contained illegal substances. Piggery waste, empty chemical drums and a separate pit of oily waste had been found. A stream flowing through the landfill was required to be diverted under resource consent - however this did not occur.
2012: The site is also known as T and T Landfill. A 2001 Montgomery Watson report indicates the site has a long history as a landfill. The report details test pits and monitoring points. The report indicates the fill materials have elevated levels of contaminants so the type of management will depend on the future intended land use. Note that there are two sites/records under SN/05/031/02.

Brandon Chambers
BRANDON ST
LOT 9 DP 10804 - BRANDON ST CHAMBERS
This site has stored hydrocarbons in bulk quantities (2000 litres) (Wellington City Council Dangerous Goods Licence). The following comments were returned by the owners of this site in March 1999. 'At some time after the 1910 construction of Brandon Chambers the coal fired boiler for the central heating system was converted to burn fuel oil and a tank for the fuel was installed within the original "tent store" within the central light well of the building. The store is a reinforced poured concrete structure standing on the main foundation slab. The tank was enclosed in a sand-filled brick built vat inside the walls of the "tent store". At some time subsequently the boiler was converted to use natural gas burners and the fuel oil pipes were removed. The storage tank was not removed. We are unaware of any incident that might have occurred during the previous use of the tank, but would suggest that the nature of the site would mean that any spill would have drained in the sewers.' Alirae Enterprises Ltd. No detailed site investigation is held by Greater Wellington and therefore the condition of the tank, or extent of contamination, if any, is unknown.

This site is used for a spray painting business. Hydrocarbons (petrol) were previously stored in larger quantities (1000 litres) according to the Wellington City Council Dangerous Goods Licence (1991). The 2003 Wellington City Council Dangerous Goods Licence lists the Maximum quantity as 500 and the container as not exceeding 60 litres. No further information is held by Greater Wellington and therefore the extent of contamination, if any, is unknown. Potential contaminants include solvents, metals and hydrocarbons.

This site has stored hydrocarbons in bulk. The Wellington City Council Dangerous Goods Licence in 1991 lists a large 10,000 and 2,000 litre tank. The 2003 Dangerous Goods Licence lists only a 2100 litre above ground tank and small quantities of dangerous goods stored in containers.
Information received (Golder Associates, July 2008) shows that a 1,600 L underground storage tank (UST) used to store diesel has been removed from the site. The dispensing lines were capped and drained but remain in situ beneath the ground. The report found no visual or olfactory evidence of hydrocarbon contamination on the excavated walls, but a slight hydrocarbon odour was noted at the floor of the tank pit. Validation sampling of the remaining soil used as the backfill recorded concentrations of PAH and TPH below relevant guidelines. The classification has not been changed as the UST has been replaced with an aboveground storage tank.

Pilbrow - Diesel Storage
TAKAPU RD
This site has been used for the underground storage of hydrocarbons. The waste oil tank and its associated infrastructure were removed in September 2005. A limited site investigation was undertaken, which indicated the concentration of hydrocarbons on the site were appropriate for the proposed industrial/commercial land use. During the site investigation waste oil was observed floating on the groundwater and discharging to the Takapu Stream. However, no assessments of the potential effects on either the groundwater or the Takapu stream or for any other potential contaminants were undertaken. Therefore the extent and nature of the potential contamination resulting from the use of the waste oil tank on the site cannot be fully quantified or assessed.

Fletcher Construction
TAKAPU RD
A large underground storage tank containing hydrocarbons was on this site according to a 1991 Wellington City Councils Dangerous Goods Licence. Some quantities of class 3 hazardous substances were stored in containers on this site up until 2003.
Information received (EnviroManagement Ltd, 1994) shows that the underground storage tank was removed from the site in 1994. Samples were collected and analysed at the time of the excavation and no residual contamination was found.

This site has previously stored large quantities of hydrocarbons on site. Four underground storage tanks and a waste oil tank were removed in 2002. The Wellington City Council audit (February 2002), of the removal, states that three tanks were corroded. However no detailed tank removal report is held by Greater Wellington and therefore the extent of contamination that has occurred, if any, is unknown. It is assumed however that any substantial contamination would have been noted in the audit. There is also no record of the contamination resulting from the use of the site as a workshop.

Butters Garage, Linden
HINAU ST
LOT 1 DP 576111 - HAVING 1/12SH IN LOT 100 DP 576111 BEING 389M2
The site was previously occupied by a service station and motor vehicle workshop. Five underground storage tanks were removed from the site in 1996. A limited investigation was undertaken when the tanks were removed. Samples of impacted soil that were collected and analysed for total petroleum hydrocarbons, information indicates that the impacted soil was subsequently removed from the site. Greater Wellington holds only limited records regarding the hydrocarbon impacted soil which was reportedly removed in 1996.
May 2019: A copy of the HD Consultants NZ Limited (HDC) limited Detailed Site Investigation report (2018) was received detailing the investigation works completed prior to the redevelopment of this site to high density residential.
Samples were collected from three test pits on the site, the number of test pits was limited by underground services and the current motor vehicle workshop activities.
One sample returned results for some heavy metals (chromium, copper, lead, mercury and lead) and total TPH above background concentrations but do not exceed the guideline values within the NESCS Soil Contaminants Standards for the high density residential land use.
The report concluded that the information reviewed and the results of samples collected indicate that there is a low risk to the inhabitants of the intended high-density residential land use. However, HDC recommended that a Contaminated Site Management Plan be developed and implemented prior to the redevelopment works to allow for monitoring of potential contamination in areas that are to be excavated, where investigation works were unable to be completed.
Based on the results and recommendations within the HDC limited DSI report this site will remain on the Selected Land Use Register classified as Category I - Verified History of Hazardous Activity or Industry until the works have been completed and confirmation has been received regarding the contaminant levels in soils that have not yet been investigated.

This site has been used for a landfill. Current land use is agricultural. According to notes on file this site was an illegal landfill on land owned by the Wellington City Council and designated for use as a cemetery. The site started operation in the 1970's and allegedly received general refuse and car bodies. Makara stream flows through the site and any leachate is likely to discharge into this stream. Based on the absence of further information the site was considered medium priority with regard to the discharge of leachate. Potential gas generation and discharge has been estimated as low (Wellington Regional Council 'Landfills in the Wellington Region" Technical Report).

LOT 1 DP 560636 - SUBJ TO AND INT IN ESMTS
The Colonial Motor Company has operated from the site for about 70 years. This site was previously a service station and has stored hydrocarbons in bulk. Three underground fuel storage tanks were removed in July 1994. No tank pull report is held by Greater Wellington for this removal and it is unknown if any contamination has occurred. Six further underground storage tanks (of unknown age) and one concrete tank bund were removed in 2004. Soil sampling was undertaken and the residual hydrocarbon concentrations were compared to Tier 1 Soil Acceptance Criteria for commercial/industrial land use (Ministry for the Environment "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand" 1999). Of the twenty-five samples submitted one sample exceeded the guidelines for xylene levels. This sample was highly localised and levels detected are expected to naturally attenuate over time. All other concentrations were below the applicable Oil Industry Guidelines.
April 2015: Property owner confirmed that the tanks removed in 2004 were in the same location as those removed in 1994.
July 2015: A motor vehicle workshop (Capital City Motors) operates from 5-11 Jessie Street, this activity has been included on this listing.

The municipal gasworks were established at this site in 1887 and continued to be used until 1910 when the works moved to another location (see file number SN/06/034/02). A gasholder continued to be used until the 1940s and the site was used as a council yard until the 1960s. A site investigation undertaken by Pattle Delamore Partners Ltd (March 2000) revealed 'concentrations of polycyclic aromatic hydrocarbons to be in excess of residential guideline values, for much of the site, at depths of less than 0.2 m'. An elevated lead concentration was also detected. A follow up report, undertaken by Pattle Delamore Partners (August 2000) recommended that 'some form of control be exercised over significant exposure pathways, in particular children playing in exposed ground, gardening activities and consumption of home grown produce'. A further site assessment was undertaken on neighbouring properties due to a proposed subdivision. Shallow soil samples found that contaminants originating from the gasworks exceeded the guidelines for residential land use by significant amounts. It is unclear what remediation or measures, if any, have been undertaken to reduce the risk to residents.

KINGSFORD SMITH ST
This site has been used by a small engineering business, including brass foundry and machining operations since the 1960s. An underground storage tank containing hydrocarbons was removed in 1996. The tank pull report indicated that some contamination had occurred and this soil was removed. Analysis of soil samples after the removal of the impacted soil from around the tank was below detectable concentrations. A Dangerous Goods Licence was issued in 2004 for a maximum of 400 x 60 litre drums.
Information received (Tonkin & Taylor, April 2007) shows that an assessment of potential for ground contamination was undertaken at the site in February 2007. Approximately 1.5m3 of foundry sand was found in an unpaved area at the northwest corner of the site. Analysis showed the sand contained elevated levels of copper, lead and zinc, with zinc levels exceeding the guideline for an outdoor worker at an industrial/commercial site. The report states that based on the proposed construction of future buildings (concrete slab with paved outdoor areas) the guideline is conservative and there is minimal opportunity for exposure of site users. It is also noted that if soil contaminated with foundry sand is to be disposed offsite during site development, the soil must be managed appropriately.
Information received (WCC, April, 2008) shows that a resource consent for the site has been granted. The site and several adjacent sites are to be developed into a large format retail activity, and this site is to be used for an outdoor plant nursery. It is proposed that the site will be covered in a 150mm slab of concrete, with the slab likely to be laid on top of the existing paving on the site. However, there is the possibility that the existing paving will be broken up and removed from the site. Any excavated soil will be tested, and disposed of appropriately.

LOTS 1 2 DP 6400
The site was previously a service station and motor vehicle workshop. When the service station operations ceased in August 2002 the four underground tanks were removed. A tank pull report confirmed that the residual contamination from the underground storage of hydrocarbons was acceptable for residential use. However, no investigation has been undertaken on the remainder of the site for contaminants associated with the motor vehicles workshops. Prior to any redevelopment of the site it is expected that some further investigation would be undertaken to ensure the suitability of the site for its intended use.

This site has a large above ground tank containing hydrocarbons presumably for a standby generator. The Wellington City Council 2004 Dangerous Goods licence also allows for up to 400 small containers (less than 60 litres) to be stored on site. No further information is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.

BP Strathmore
BROADWAY
LOT 1 DP 9280
This site was originally developed in 1950 as a service station and workshop. Strathmore motors took over the site in 1993 and the service station facilities were removed and replaced in 1998.
Seven underground storage tanks were removed in February 1998. Two areas of the soils sampled had levels of residual hydrocarbons exceeding relevant guidelines. A site management plan was suggested to reduce the risk to maintenance/excavation workers. Greater Wellington does not hold a copy of this plan.
Two fibreglass tanks were removed in August 2003 when the site was decommissioned. Subsequent soil sampling from this tank area found that all soil samples complied with the applicable Tier 1 Soil Acceptance Criteria for commercial/industrial land use (Ministry for the Environment "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand", 1999). It is not known if these samples were taken from the same location as the tanks that were removed in 1998 and therefore whether any contamination remains.
A motor vehicle workshop remains on site. There is currently waste oil (2x 600 litre) and lubricant (3x 550 litre) within tanks which are stored indoors and within secondary containment.

Homebush Park
RAUMATI TCE
This site has been used as a landfill. It operated intermittently for 15 years accepting approximately 37,500 m3 of primarily domestic and industrial waste. There is some anecdotal evidence that potentially hazardous domestic and industrial wastes were disposed of at the site. Soil sampling undertaken in 2002 found that metal concentrations were below the recommended guidelines for the protection of environmental and human health. Hydrocarbons were not detected.
Information received (MWH report, July 2005) shows that a soil contamination and leachate characterisation project was undertaken at the site. The landfill cover comprises a layer of loose, silty gravel that frequently contains refuse. Geophysical surveys indicate waste is present across the entire site in the 1-3m depth range. Waste was also found to be poorly compacted., which could cause a risk of subsidence. Confirmation of leachate was obtained from a monitoring well installed in the vicinity of the landfill toe. Leachate contained elevated levels of heavy metals, particularly lead, chromium and zinc.
Information received (AEE, 2005) shows that the cap was excavated and replaced with imported cleanfill, clay and topsoil. The works were completed in January 2006.

Waitomo Self Service Johnsonville
OHARIU RD
This site has been used as a motor vehicle workshop and service station. In 2003 there were three underground storage tanks and three aboveground lubricant tanks on site. The tanks were installed in 2001 following the removal of the original tanks (installed in 1958). Reports viewed by a Greater Wellington (but not held) state that there was no residual contamination at the site when the new tanks were installed. A 2003 'Take Charge Assessment' by Greater Wellington Officers found that while "there was no evidence of significant environmental pollution or contamination" associated with the service station, there was evidence of leakage of hydrocarbons from inappropriate waste disposal practices by the workshop on site. This does not appear to have been investigated further (2006).
2019: the site changed from Challenge Young Motors / Jville Car Maintenance to a Waitomo self-service station.

HUTCHISON RD
The site was used as a landfill. The ex Tin Tip was filled with industrial wastes including tins, trade waste and possibly hospital incinerator waste. The landfill was finally capped with clay.
Information received (URS, 2007) shows that a soil contamination and leachate characterisation project was undertaken at the site. The geophysics results indicate that there is a high likelihood of buried refuse on the site. Historical photographs and discussions with a site manager also confirm this. The general low conductivity, and age of the landfill were found to indicate a low likelihood of concentrated leachate being present. The surface of the site is predominantly asphalt. No soil or groundwater samples were taken.
Information received (ConnellWagner, 2009) shows that a geotechnical investigation was undertaken on the upper carpark, for the purposes of an artificial sports field proposal. Test pit logs confirm the site has been used as a landfill in the past. Landfill material encountered included bricks, glass, concrete, metal, clinker and wood. The report states that previous investigations found similar fill material. A study in 2004 encountered a test pit with a strong diesel fuel smell. The 2009 test logs show cleanfill at depths of at least 1.5m, while the 2004 test pit logs show cleanfill at depths of at least 0.5m.

Feb 2024: Pattle Delamore Partners Limited (PDP) were engaged by Petroleum Solutions Limited to remove the disused underground petroleum storage system (UPSS), associated pipework (fuel line, vent line, dispenser), and to undertake soil sampling under the NESCS regulations. The 10,000L tank containing 91 Unleaded Petrol was located beneath a concrete slab and was in relatively good condition. A total of 18 samples were taken, this included sampling the interior walls, base of the pit, bedding material, pipework trench and beneath the dispenser. Soil was tested at varied depths for hydrocarbons, which were found, but are at acceptable standards for commercial/industrial land-use and do not pose a risk to groundwater or future site users. It is unknown if the larger tank still exists onsite.

This closed landfill was on land owned by the Anglican Church that was subsequently subdivided and redeveloped into residential properties. The landfill was operated by the Wellington City Council in the early 1930’s and accepted general rubbish from the Karori area.
Feb 2014: Technical report received from Golder Associates (Document number 1313829) confirmed the presence of significant surface soil contamination of lead and arsenic that exceed the NES soil contaminant standards for residential land use. Classification was therefore changed from verified HAIL to 'Contamination Confirmed'
March 2016: This site has undergone remediation works, an Elementary Consulting Site Validation Report (2016) indicates that the site is now suitable for ongoing residential purposes (subject to the Monitoring and Management Plan).
The report indicates that uncovered soils were excavated to 0.5m below ground level (sealed driveway areas 0.3m bgl) and a geotextile fabric layer was installed at this depth. Clean imported materials were used to fill to ground level and landscaping works took place on both properties. No remedial works have been undertaken beneath the dwellings.

This site has been used as a timber treatment plant from the 1960s until 1992 when all equipment was removed. Timber treatment processes were antisapstain based using PCP, copper-chrome-arsenic (CCA) and boron. In 1999 significant quantities of contaminated soil (300 m3) containing CCA was removed. A site investigation undertaken by Montgomery Watson in 1999 found that the samples were generally within the guidelines for commercial/industrial use and in one area complied with agricultural use. However one area of the site (the woodwaste landfill) contained elevated levels of CCA (See also SN/08/099/02). Groundwater sampling indicated that boron and arsenic levels exceeded irrigation and drinking water guidelines in some locations.

Martinborough Sawmills Ltd
NEW YORK ST
This site has been used as a mill and does some antisapstain treatment. The drip/storage area for freshly treated timber is not bunded. A site investigation was undertaken by Montgomery Watson in 2001. This report shows that the levels of PCP (antisapstain spray pentachlorophenol) at the site are low and largely confined to the area associated with the historical operation of a dip tank. The report compared the level of PCP with the relevant guidelines for timber treatment for agricultural and residential use. However it recommended that the top 100mm of soil be excavated from the historical dip tank area before the growing of vegetables. Potential hot spots may still exist at the site however the investigation targeted worst case areas and these results complied with relevant guidelines.

This site was a landfill and has been filled on two occasions. The most recent was in 1994 when cleanfill construction material placed onto the site. Fill from the 1930s included Tin Tip material (from incinerators) dumped lubricating drums, fuel oil, corrugated iron, petrol tins, barrels of broken glass, steam boilers, discards from a demolished electricity powerhouse, tar, drums, iron castings, car bodies and sheep carcases. Metallic waste was specifically dumped at the Birdwood Street end. Tin jars were placed on ground level and filled with clay. Bottles were mass spread in regular level 4-6 feet deep. A foot of clay is on top of this. Water sampling has been undertaken for this site.
Information received (MWH report, 2005) shows that a soil contamination and leachate characterisation project was undertaken at the site. Generally the landfill cap was found to be in good condition. Landfill waste was present in distinct horizons at depths varying from 0.8m-3.2m. A range of refuse was found. Two boreholes drilled at the site had to be abandoned due to a hard metallic object. Confirmation of leachate was obtained from a monitoring well installed on site at a depth of 21.4m. The leachate was found to contain particularly high levels of zinc and lead. However, surface water quality of the Kaiwharawhara Stream was measured in a previous MWH (2004) study at a site 200m downstream, which showed that only very minor levels of leachate may be discharging to the stream.

The surface of the site is predominantly sealed and used as tennis courts, so no soil samples were taken. The geophysics results indicate that there is a low likelihood of buried refuse at the site. This is based on low electrical conductivity levels across the site and results from the GPR survey. The low conductivity observed also indicates there is a low likelihood of concentrated leachate within the landfill.

Closed Horokiwi Landfill
LADBROOKE DR
This site has been used as a landfill which has accepted both community and industrial waste. A report on file notes that the entrance to the site was not manned and therefore industrial and commercial refuse was unable to be properly inspected or controlled. Hazardous wastes were accepted on rare occasions. A report in 1990 noted that leachate was twice as strong as secondary treated sewerage and was discharged to the stream. Areas of the tip were clean-filled after closure. The landfill gas was identified as a risk to the public in 1995. This gas generated was proposed to be collected and used for power generation (1996), however it is unknown if this has happened. The area was intended to be used as reserve land.
Information received (URS report, February 2007) shows that a Phase 2 site investigation was undertaken at the closed landfill at Horokiwi. The report notes that the landfill has a leachate discharge and treatment system authorised by the way of consent (WGN 000048 20122), which was due to expire in 2006, and for which a new consent is reportedly being sought. The surface of the site was found to be in good condition with the GPR results indicating the cap is likely to be approximately 0.5m in thickness, and continuous across the landfill. The report states that heavy metal and TPH concentrations in the landfill cap soil samples were all below MfE (1999) Guideline All Pathway values, and generally consistent with or slightly exceeding background levels.

Central Park (ex landfill)
BROOKLYN RD
This site was previously a landfill. There is no information on file regarding the contents of the fill although it is likely to have received general refuse. A Wellington Regional Council Report (date unknown) noted that there was significant iron staining in the storm-water outlet. Levels of iron and zinc exceeded ANZECC criteria and would pose an unacceptable risk if the water was to be used for stock watering or entered a significant ecosystem without adequate dilution. On this basis the site is considered medium priority with respect to the discharge of leachate. Due to the age, size and type of refuse disposed of at the site, potential gas generation and discharge has been estimated as low.
Information received (URS report, December 2006) shows that a phase two site investigation was undertaken at the site. The surface of the park is predominantly sealed with either asphalt or tennis court surfacing material and is in good condition. The capping layer is estimated to be 0.8 - 1.0m thick. Orange iron staining was observed in one of the streams that flows from the site. No samples were analysed.

Information received (MWH, 2005) shows that a soil contamination and leachate characterisation assessment was undertaken at the site. The integrity of the landfill cap was found to be good. No evidence of soil contamination was found in the capping material, with concentrations of heavy metals and total petroleum hydrocarbons reflecting background levels. There was also no evidence of typical landfill refuse in the test pits, augers or boreholes. No groundwater was found in the deepest bore (8m), hence leachate characteristics could not be determined for this site.

The tank was in reasonably good condition when removed, with no odour apparent in the surrounding backfill. All fill and groundwater in the pit was removed before being replaced with imported clean fill. It is not known if any soil samples were taken and therefore, and although unlikely, whether any contamination has occurred.

Information received (URS report, June 2006) shows that the underground petroleum storage system (UPSS) containing two underground storage tanks (USTs) was removed from the site in May 2006. At the time of removal, eleven soil samples were collected and submitted for total petroleum hydrocarbon (TPH) analysis, and seven for BTEX analysis. The report found that all samples complied with Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand (MfE, 1999), except one sample that exceeded criteria for protection of maintenance and excavation workers and protection of groundwater quality, for total xylenes. However, this one sample was considered to represent a small volume of cohesive soil directly underlying the remaining dispensing lines. No BTEX or TPH was found in samples taken from the same location but at different depths, therefore, it was considered that the exceedence does not indicate a significant environmental risk. No soils were disposed of during the works. The site is a motor vehicle workshop and is to remain in this use.

This site has previously stored hydrocarbons in bulk and is currently used for automotive dismantler/wrecking. The three underground storage tanks on site were removed in March 2001. Subsequent soil sampling from the tank area found that all soil samples complied with the applicable Tier 1 Soil Acceptance Criteria for commercial/industrial land use (Ministry for the Environment "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand 1999). The tank pit area can therefore be considered a remediated site, however the continued use of the site as an automotive wrecker means that the site in general will be classified as a site that has used or stored a hazardous substance.

The site has previously been used as a landfill. The landfill operated between 1937 and 1940 and received rubbish and ash. There were a number of potential sources of ash at that time, the municipal incinerator, the Evans Bay coal fired generator and the Miramar gasworks. A site investigation undertaken on the site showed these fill material contained elevated levels of heavy metals and poly aromatic hydrocarbons. The site was remediated in 2003 when a capping layer was placed over the fill materials to prevent access to the contaminants. The cap comprises a geo-textile marker layer covered with 0.4m of clean imported fill and 0.1 m of topsoil. The sites are considered suitable for residential use providing the capping layer remains intact.

This site has previously stored hydrocarbons in bulk. Three underground storage tanks (USTs) were installed in the mid-1960s containing petrol (regular, super) and diesel products. Two USTs were relocated in the early 1970s. Two USTs were removed from the site in 1997, and all hydrocarbon impacted soil was removed from the site at the time of removal, and the remaining soil did not exceed soil acceptance criteria.
Information received (Aurecon, 2010) shows that the one remaining UST was removed from the site in April 2010. At the time of excavation soil samples were collected from the sides and base of the pit. All samples complied with the MfE guideline values for commercial/industrial use. It is believed that the site is to be developed and the area where the UST was located is to be paved with asphalt and concrete.

This site has been used as a TransAlta Depot. Prior to 1989 several underground storage tanks were located in front of the old vehicle workshop. It is unknown if these tanks have been removed as their exact location was unable to be determined. It is thought likely however that these tanks would have been discovered however during excavation. Three (separate) underground storage tanks were removed from the site in 1997. An environmental assessment undertaken by Pattle Delamore Partners Ltd (1997) identified oil in the ground near the transformer oil storage tanks and slightly elevated concentrations of polycyclic aromatic hydrocarbons in coke-like waste under parts of the carpark.
Excavation work identified further areas of oil - limited sampling undertaken in 1999 found that petroleum hydrocarbon levels were within acceptable residential guideline levels. Service trenches were to be sealed, covered with an impermeable layer and then topped with concrete. The site was therefore considered suitable for residential use. A site management plan may be required if further subsurface excavation work is undertaken.

Aotea Wharf
Any other land that has been subject to the intentional or accidental release of a hazardous substance in sufficient quantity that it could be a risk to human health or the environment
DDT (dichloro-diphenyl-trichloroethane) was identified in harbour sediments around Aotea Wharf in 1995. An investigation by Woodward and Clyde found that although the DDT had begun to degrade it was still present in toxic levels. There was considerable spatial variability in the concentrations of total DDT measured in the sediments. It appears that the highest residues are around the stormwater outfalls. The main risk presented by DDT is the adverse effects on the biota near Aotea Quay. It was assessed that there is little immediate or short term risk to human health posed by the sediments but that long-term risk were uncertain. It was thought probable that the impact of dredging and removing the sediments for treatment may be even greater than leaving them in place. It was recommended that the sediments remain and if possible capped. It is unknown if this option has been investigated further. See also Site No SN/05/135/02.

Information received (MWH, 2006) shows that an environmental assessment was undertaken at the site in March 2006. The report states that the site has been in operation since 1959, mainly for the storage of bitumen, but also the storage of diesel and kerosene. The investigation involved the installation of two cathodic protection wells, drilling three bore holes and installation of two monitoring wells. Nine soil samples and two groundwater samples were collected, and it was stated that the TPH and BTEX concentrations for the soils complied with MfE guidelines.
Information received (URS, 2008) shows that two underground storage tanks (USTs) and three aboveground storage tanks (ASTs) were removed from the site. Soil samples were taken from the UST pits at the time of excavation. The report states that all samples representing soil remaining on site complied with relevant criteria in the MfE guidelines. However, it is also noted that semi-solid clumps of bituminous material and clinker waste clumps were observed as being generally present in near surface soils (<1m) in the AST farm area, and excavation in the former UST1 and UST2 areas may encounter some staining and petroleum hydrocarbon odours.

Prior to 1998, the site had for over forty years, been used as a service station and motor vehicle workshop. In 1998, the site was decommissioned and the fuel storage tanks removed. A site investigation at this time showed elevated concentrations of hydrocarbons to be present on the site. Further remedial works were undertaken and all significantly hydrocarbon contaminated soils were removed from site. The validation of the remedial works indicated that there was no significant risks from residual hydrocarbon contamination should the site be used for a residential use. However, no investigation were undertaken to address any potential contamination from the workshop activities on the site.

This site is a service station and a fast food store. The petrol and diesel are stored in underground storage tanks and liquefied petroleum gas is stored in an aboveground tank. Greater Wellington Regional Council does not hold any information on its Selected Land Use Register detailing the presence or otherwise of any contamination on the site.

Caltex Island Bay
THE PARADE
SEC 14 TOWN DISTRICT
This site is used as a service station. There are eight underground storage tanks (USTs) on site and four of these are disused. There are six 300 litre aboveground storage tanks for lubricant oils in the vehicle maintenance workshop. Although the estimated age is not stated, a Greater Wellington 'Take Charge Assessment' in 2003 states that there is potential for soil and groundwater contamination via historical product leakage given 'the likely age' of the tanks. This site assessment also found evidence of ongoing contamination of stormwater run-off at the site via product spillage onto the forecourt, and oil spills/leaks around the waste skip and waste oil disposal point (2003).
Information received (URS report, May 2008) shows that seven USTs were removed from the site. Approximately 42m3 of impacted soil was also removed from the site. With the exception of three samples, concentrations of contaminants in soil samples representative of soil remaining on site complied with relevant Ministry for the Environment guidelines. The report identifies a localised area of total petroleum hydrocarbon (TPH) contamination above relevant guidelines within the C7-C9 range, beneath the former dispensers. Groundwater samples were also taken from two monitoring wells located on the site. Analysis showed that contaminant concentrations in the groundwater samples were all below laboratory detection limits. Greater Wellington holds no information with regard to any possible contamination associated with the vehicle maintenance workshop.

This site comprises of three lots. Lot 1 has previously been used for the maintenance and repair of motor vehicles and lot 2 previously used as a service station. Lot 3 has been used as a service station and as part of this operation bulk hydrocarbons were stored in underground and aboveground tanks. Lots 1 & 2 have undergone a limited site investigation which has indicated that there is no significant contamination in the soils on site.
Information received (URS report, February 2008) shows that the underground petroleum storage system, containing four underground storage tanks (USTs) were decommissioned and removed from the site. Analysis of soil samples representative of soils remaining on site were at or below laboratory detection limit for total petroleum hydrocarbons (TPH), except one sample below the former dispenser which contained residual diesel. However, the report states that the sample does not exceed relevant Ministry for the Environment guidelines.

The site has been used as a service station. The site was closed and the four tanks were removed in 2003. A tank pull report in 2004 detailed the residual hydrocarbon contamination on the site. The report stated that there was residual contamination present on the site, but that it was suitable for industrial/commercial use. In January of 2005 excavation work discovered further hydrocarbon contaminated material and a concrete containment tank. An MWH report (#1121826) on soil sampling indicated that contaminated soil was of sufficient low concentration that it could remain on site with no further required treatment. Contaminated surface water was collected and disposed of and the containment tank was filled.
2014: Information received (doc#1337925) for tanks removal in March 2014 from site known as Hirequip (Pt lot 7 DP1362).

Former Shell Vivian St now Z Energy
VIVIAN ST
LOT 1 DP 54050 LEASED AREAS A B ON DP 56212
This site was a service station. A waste oil tank was removed in August 2003. This tank was thought to be approximately 40 years old. On removal a large amount of waste oil was on top of the tank. This product was removed off site. The subsequent tank pull report confirms that the residual contamination around the waste oil tank pit meets the industrial/commercial criteria in the 'Guidelines for Assessing and Managing Petroleum Hydrocarbons Contaminated Sites in New Zealand' (Ministry for the Environment August 1999).
Information received (URS 2009) shows that site has been decommissioned by Shell. The underground petroleum storage system containing three underground storage tanks (USTs) and associated pipework was removed. Soil testing at the time of the UST removals found that generally soil remaining on the site is acceptable for a commercial/industrial land use, in relation to the MfE guidelines. However, one sample at a depth of 3.8m exceeded the guidelines for C7-C9 hydrocarbon range and total xylenes. The report states that this exceedence is assessed to be not significant given the likely limited extent that is indicated by the depth (3.8m) of contamination and the presence of the subterranean drain located to the northwest. All groundwater samples were found to comply with the relevant guidelines. Test pitting beneath the workshop and lube bay did not detect any residual petroleum hydrocarbons.
2014: Information received (PDP Ltd report dated 18 June 2013 #1233842) reported on pre excavation soil sampling and validation investigation. The report indicated that the site is being redeveloped into a Z Energy service station (166-180 Vivian St). See report for further details.

The site has been used as a service station and motor vehicle workshop since the early 1960s. The service station was decommissioned and the underground fuel storage tanks were removed in February 2004. The soil around the tanks and associated pipe work was sampled and analysed in accordance with the 'Guidelines for the Assessment and Management of Petroleum Hydrocarbon Contaminated Sites in New Zealand' Ministry for the Environment 1999. The finding of the investigation were detailed in a report which showed the residual hydrocarbon contamination on site is generally suitable for industrial/commercial use, however there are areas were the hydrocarbon concentration exceeds the guidelines for indoor inhalation and the protection of maintenance excavation workers. No assessment has taken place into any potential contamination resulting from the use of the site as a motor vehicle workshop. Both of these activities were no longer in operation in 2004.

LOT 2 DP 88019 - INT IN R/W
This site has been used as a service station and motor vehicle workshop. On site were three underground storage tanks containing hydrocarbons (2003). It was observed that a tank pull occurred in February 2006. No detailed site investigation or tank pull report is held by Greater Wellington and it is unknown if the tanks were replaced of if any still remain in the ground. It is also unknown if any contamination has occurred. It is assumed that the motor vehicle workshop is still operating.

Shell Strathmore
2007: This site is a service station and motor-vehicle workshop which has been operating on site for over 20 years (2003). The tanks and pumps at the station have been replaced over the years, although the details of replacement dates and tank construction are not known. There are currently three underground storage tanks (containing hydrocarbons) on site. There is also a plastic waste oil and coolant tank and two unbunded bulk lubricant oil tanks. No detailed site investigation is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.
2012: Information was received that 3 fuel storage tanks are planned to be removed in October 2012.
April 2013: A report received (doc#1203298) from PDP Ltd indicated that three UPSS tanks were removed in December 2012. Soil samples were taken in remaining soil. Some soil samples exceeded criteria (see report for further details) so a site management plan was recommended to assist future site workers in managing exposure. Some soil was removed from the location. The report indicated that it is possible that hydrocarbon impacted soil extends off site in the vicinity of the former remote fill points but the extent of contamination, if any, was not assessed. The report considered the risk to ecological receptors via direct groundwater migration to be negligible.
January 2014: A report received (doc#1307528) from PDP Ltd indicated that additional soil samples were taken. The report concluded that previously inaccessible parts of the site are considered to have an acceptably low risk.

Creswick Tce Park (ex landfill)
CRESWICK TCE
This site has been used as a landfill, the current site use is recreational and possibly includes house sites at the end of Creswick Terrace. Surrounding land use is residential. The site is considered relatively low priority with respect to the discharge of leachate and landfill gas according to the 'Landfills in the Wellington Region' Wellington Regional Council Technical Report.
Information received (MWH report, 2005) shows that a soil contamination and leachate characterisation assessment was undertaken at the site. The integrity of the cap was found to be generally good with a thickness of 0.7m to 1.2m. No evidence of soil contamination was found in the capping material. The fill was found to contain a range of waste, predominantly domestic. Weak leachate was obtained from a monitoring well installed in the centre of the landfill. The leachate contained elevated levels of zinc and lead, and also high BOD, which may have come from seepage of sewage from a sewer pipeline. There is no evidence of any leachate discharging off-site.

PT LOTS 4 5 DP 69 PT SEC 228 229 TOWN OF WELLINGTON
This site has been operated by Shell since the late 1980's. No information is known regarding site contamination, or the condition or history of underground tanks at the site. There are four underground storage tanks containing hydrocarbons on site, as at 2006.
An application dated March 2012 to Wellington City Council to install an API interceptor for stormwater drainage and an Assessment of Environmental Effects (AEE) was received via Wellington City Council. It was proposed that approximately 8m3 of soil was to be removed. Further information and the full report is on file SN/05/150/02.
September 2012 ' PDP Ltd supplied GW and WCC with a copy of the soil benchmarking sampling report undertaken during re-piping of fuel lines for the underground petroleum storage system (UPSS) at 155 Taranaki Street, Wellington, during March and April 2012. The UPSS is directly north of the canopy and dispensing area and contains four USTs, two 40,000L 91 petrol tanks, one 30,000L 95 petrol tank and one 20,000L diesel tank. The report indicates that the fuel line pipework was exposed and soil samples collected by PDP from beneath the pipes. The report indicates that four samples were collected and analysed for total petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene and total xylenes (BTEX). The report indicates that one of the four samples had a BTEX constituent above laboratory detection limit but the laboratory results show that the sample complied with the MfE (2011) Tier 1 acceptance criteria via the All Pathways for commercial/industrial land use. The report indicates that all other laboratory results for BTEX and TPH were below the detection level. The report indicates that the soil sampling results indicate that there is no significant risk to site users or workers involved in subsurface excavations in the vicinity of the fuel lines. The report indicates there is considered to be no significant risk to any ecological receptors from residual petroleum hydrocarbons within the vicinity of the removed fuel lines.

2006: This site has operated as a service station and motor vehicle workshop since 1928. Shell took over the site in 1980. It is believed that the current underground tanks were installed in 1976. There is no documentation concerning the past removal of these older tanks or any environmental sampling that may have been undertaken at the time to characterise potential soil or groundwater contamination. One tank was removed from the site in 2005. The tank pull report shows that the soils around the tank contained no significant hydrocarbon contamination. The report states that a hydrocarbon sheen was present on the groundwater; however, no sample was taken to determine the nature or concentration of the hydrocarbons. As no sample was taken the source of the contamination is unclear. Three underground storage tanks remain on site (2005). No detailed site investigation is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.
2014: Information received (PDP Ltd report #1394212) on Z Kilbirnie, 16 Coutts St. The report was on investigation prior to a knock down and rebuild, and included soil sampling. The site is undergoing redevelopment into a new shop and UPSS by Z Energy. See report for further details.

Shell Constable St
CONSTABLE ST
This site is a service station and there reportedly were three fibreglass underground fuel storage tanks and a gas cylinder at the site (2003). No detailed site investigation is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.
2024:PDP undertook groundwater sampling at the Z energy service station to assess the current concentrations of residual petroleum hydrocarbons, due to the historic records of reported benzene concentrations very close to or marginally exceeding the residential/agricultural land use Tier 1 guidelines for indoor air inhalation at well MW1. Overall, no product was measured in wells MW2 and MW3. 0.001 m of product was measured in MW1, with hydrocarbon globules and a sheen observed on purge water. However, it was concluded that the dissolved phase plume present in the vicinity of MW1 is now stable, due to TPH and BTEX compounds being below the Tier 1 guidelines. The potential exposure pathway to adjacent residential property users is considered by PDP to be incomplete and the residual hydrocarbons can be managed via natural attenuation processes.

This site has been used as a service station and a motor vehicle workshop. The service station began operating in 1980. There are two underground storage tanks of steel construction and a smaller waste oil and lubricant currently on site. A 'Take Charge Assessment' undertaken by Greater Wellington in 2003 found that while there was no evidence of any contamination associated with the service station there was clear evidence that contaminated workshop operations were flowing into the site stormwater drain. No detailed site assessment is held by Greater Wellington and therefore the extent of contamination, as a result of current and past practices, is unknown.
Pattle Delamore Partners (PDP) Site Validation Report of the Decommissioning of the Z Energy Limited-service station (December 2023) was received, for the full report see CNMG-8-3284. This report identifies seven tanks, fuel lines, and the remediation works associated with the site. 72 soils samples were collected and analysed. A total of approx. 109 tonnes of contaminated soil (40.28 tonnes of hydrocarbon impacted material) and natural materials (68.56 tonnes) was removed and disposed of at Southern and Silverstream Landfill. Remaining material onsite reported concentrations of heavy metals and PAH below the NES for commercial/industrial land use. The vehicle workshop was not investigated, or the tanks marked as unknown. Z did not respond regarding GWRC SQEP questions if the inceptor had been removed or confirmation that tank pit TPI walls were competent with no fractures.

Shell Miramar
MIRAMAR AVE
2007: This site was originally used for storage of diesel and bunker oil petroleum product to service shipping at the Miramar Wharf. Between the 1920's and the 1960's five underground storage tanks were on site. When the site was vacated all but one tank was removed. This last tank was removed in the 1970's. See Site No SN/05/032/02. This part of the site is used as a service station. There are three underground storage tanks on site and one above ground storage tank also on site. The age, construction or condition of the underground fuel tanks is not known.
2014: A report was received (doc#1308196) from PDP Ltd on Phase 2 site investigation to characterise hydrocarbon contamination found in the vicinity of the tank pit, and to determine the extent of residues by benchmarking soils and groundwater. The report concluded that groundwater samples collected and analysed from monitoring wells confirmed that groundwater has been affected in some areas of the site. The report concluded that groundwater samples analysed from the newly installed monitoring wells reported concentrations below the applicable criteria in the context of commercial / industrial land use, and therefore do not represent an unacceptable risk to human health.

This site has previously been occupied by a service station and a motor vehicle workshop.
Information received (URS report, May 2010) shows that the underground petroleum storage system consisting of five underground storage tanks (USTs) has been removed from the site during the site's decommissioning. At the time of the UST removals, soil samples were taken at various locations and analysed for residual contamination. The results from the analysis show that all samples representative of soil remaining on site had concentrations that complied with the corresponding oil industry guidelines for an industrial/commercial land use. Approximately 9 tonnes of impacted material was taken from the site and disposed of at an appropriate facility.

The site has operated as a service station for over sixty years and prior to that, the site is understood to have been occupied by the railways. The service station was decommissioned and the underground storage tanks were removed in June 2004. A site investigation was undertaken in accordance with the Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand ' Ministry for the Environment 1997, which found elevated concentrations of Hydrocarbons were present on the site. The soils which contained the highest concentrations of hydrocarbons were excavated and removed from site. The areas from which the soils were removed were validated and shown to be suitable for commercial/industrial use. However, there is residual contamination on the site which may pose a low risk to construction maintenance workers. To further protect these maintenance/construction workers a site management plan has been produced to mitigate any potential risks from the hydrocarbons.
Site Validation Report carried out by Tonkin + Taylor in September 2020 [CNMG-8-2714]. The report concluded that following remedial activities the ground contamination at the site was within the applicable guidelines for the protection of human health for the intended use as a convention and events centre

This site has been used as a landfill and is now used as a recreational area. Surrounding land uses are residential and a secondary school. The site is considered relatively low priority with respect to the discharge of leachate and landfill gas (Wellington Regional Council 'Landfills in the Wellington Region' Technical Report).
Information received (URS, 2007) shows that a soil contamination and leachate characterisation project was undertaken at the site. Generally, the surface of the park appeared to be in good condition. The landfill cap was measured to be between 0.2 and 0.7m bgl across the site. Analytical results of soil samples collected from the cap showed no evidence of soil contamination. Landfilled waste was found during drilling over a 1m interval at a depth of approximately 0.4m bgl. Based on the logs of the boreholes, the waste is suggested to be comprised of gas works waste (clinker) and domestic waste. Analysis of a waste sample found slightly elevated heavy end hydrocarbons and chromium, but concentrations were below guideline values. Leachate was encountered in one well, and was found to contain high levels of Ammoniacal-N.

This site is a service station with a motor vehicle workshop. Hydrocarbons are stored in three large underground storage tanks and one smaller waste oil container (1000 litres). The age of the steel tanks is unknown. The current location of the workshop was previously a petrol station. It is possible that disused underground storage tanks (potentially 60 years old) remain in this part of the site. A leakage of oil from cracks in the ground was noted on file in 1994. It is unknown if any remediation was required or undertaken. Greater Wellington holds no detailed investigation for this site and therefore the extent of contamination, if any, is unknown.
July 2016: An Underground Petroleum Storage System (UPSS) Decommissioning Report was received from AECOM. This report details the removal of the former UPSS and excavation of impacted material which were undertaken as part of a site upgrade in April/May 2016. The removed UPSS was comprised of three underground storage tanks (40,000L 91-octane, 40,000L 95-octane and 15,000L diesel).
Soil sampling was undertaken as part of the decommissioning works and samples were analysed for contaminants associated with hydrocarbons. For full details on the results see CNMG-8-552.
This site has been upgraded by the owner and will continue to operate as a BP service station.

This site has been used as a service station. There are three underground storage tanks containing hydrocarbons on site (2004 Dangerous Goods Licence). No further information is held by Greater Wellington for this site and therefore the extent of contamination, if any, is unknown. Potential contaminants include hydrocarbons, lead and copper.
January 2013: URS provided a tank pull report (ref #1164206) for the decommissioning, removal and replacement of the underground petroleum storage system (UPSS) and the associated soil sampling residual assessment. The decommissioning report indicated that the existing UPSS was removed from the site and the report benchmarked the excavation as the site is to remain a service station and has been re-tanked by BP.
The report indicated that the analytical results showed that the soil remaining on site complied with the corresponding Oil Industry Guidelines Soil Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use.

This site was filled twice with clean fill in approximately 1980. The current land use is a botanic garden and the site is used for open space/recreational. The site was visited in May 1995. Tractor tyres and wire cable were observed in the stream and rust coloured leachate oozed from the bank and clean fill material moving down towards the Kaiwharawhara Stream. Sampling in the stream indicated elevated levels (exceeding guidelines for the protection of aquatic ecosystems and stock watering) of iron directly below the predominant seep with this level reducing somewhat downstream. Landfill leachate was classified as of high priority and further investigation was suggested to determine the risks associated with the discharge from this site (Landfills in the Wellington, Regional Council Technical Report 1998). No information is held by Greater Wellington to indicate whether this has occurred.

This site was previously a service station storing in bulk hydrocarbons. Four underground storage tanks were removed in November 1995. Soil sampling taken around the tank pits following their removal found moderate to high levels of TPH (total petroleum hydrocarbons) and elevated to a very high levels of xylene. The concrete walls separating the tanks were in poor condition. It is not known if the highly contaminated soil identified in this report was removed.

Queens Wharf
Any other land that has been subject to the intentional or accidental release of a hazardous substance in sufficient quantity that it could be a risk to human health or the environment
DDT (dichloro-diphenyl-trichloroethane) was identified in harbour sediments around Queens Wharf in 1995. An investigation by Woodward and Clyde found that although the DDT had begun to degrade it was still present in toxic levels. There was considerable spatial variability in the concentrations of total DDT measured in the sediments. It appears that the highest residues are around the stormwater outfalls. It was assessed that there is little immediate or short term risk to human health posed by the sediments but that long-term risks were uncertain. It was thought probable that the impact of dredging and removing the sediments for treatment may be even greater than leaving them in place. It was recommended that the sediments remain and if possible capped. It is unknown if this option has been investigated further. See also Site No SN/05/177/02.

BP Karori
This site is used as a service station and vehicle maintenance workshop. Three underground storage tanks (USTs) store hydrocarbons in bulk and are understood to be steel vessels installed in concrete chambers. The age of the underground tanks is unknown. An above ground waste oil tank is also present and has no form of secondary containment (unsealed). There is evidence of localised soil contamination around this tank. A Take Charge Assessment in 2003 undertaken by Greater Wellington reported that the lubricants and solvents stored in the workshop were not provided with adequate secondary containment. There was also no stormwater protection device (2003).
Information received (URS, 2010) shows that the three USTs were removed from the site and replaced with new tanks, as the site is believed to still operate as a service station. At the time of the UST removals, soil samples were taken and analysed for residual contamination, and some impacted material was removed from the site. The results found that one sample exceeded guidelines for maintenance/excavation workers and for volatilisation to indoor air, however, as the site is to remain as a service station these guidelines do not apply and any risk should be managed by the workplace exposure standards. However, the area of contaminated material remaining onsite is considered to be limited in extent, and it is unlikely that the impacted material extends under neighbouring property. If land use is to change, the potential risk associated with residual hydrocarbons remaining onsite should be re-assessed.

This site has been used for Railway Yards. It was reclaimed from the harbour between 1882 and 1932 using a variety of fill material. Originally it was occupied by wharf facilities and later as rail marshalling yards from at least 1938. Part of the site had been used as a coal stockpile area. A Site Assessment report was undertaken in December 1995. The low level of contamination was thought unlikely to pose any risk to stadium users, nor any significant risk to the environment. The site is completely covered by sealed surfaces and the playing field and the sports field is covered in 600 mm of clean fill. There is potentially a risk for workers undertaking any future excavation work at depth. A site management plan would address this issue. There is a dangerous goods license for a gas cylinder (2004).

This site has been used as a service station for over fifty years (2003). There are seven underground storage tanks on site. Two of these are abandoned and their size and construction is unknown. A spill occurred in 1994 during the installation of a new diesel tank.
Information received (URS, Dec 2010) shows that seven underground storage tanks (USTs) were removed from the site. Approximately 130 tonnes of bedding material from tank pit 1 and soil from the dispenser excavation was removed from the site. Numerous soil samples were collected at the time of excavations and analysed to determine residual contamination. The report states that concentrations of petroleum hydrocarbons were detected in soil at depth within the north wall of tank pit 1 which exceeded guidelines for maintenance/excavation workers. It appears the impact is limited in extent, however, appropriate precautions should be taken when excavating soil at depth.
September 2015: This site is currently occupied by a motor vehicle workshop - 'Auto Super Shoppe, Thorndon'. See #1526109 for further information.

Ex BP Khandallah Service Station
BURMA RD
The site was previously a service station and a motor vehicle workshop. In August 1997 the underground storage tanks which held petrol, diesel and turpentine were removed. As part of the tank removal, an environmental investigation was undertaken which involved the taking and analysis of soil and water samples to determine the extent and nature of the residual contamination on the site. The significantly contaminated materials were removed from the site. However, the result of the analyses showed that the residual contamination on site exceeds the guideline for the protection of construction/ maintenance workers and therefore a site management plan was required. With respect to the underground storage of hydrocarbons the site is considered suitable for commercial/industrial use providing controls were in place.
The site was to continue as a motor vehicle workshop, therefore no investigation was undertaken to determine any potential contamination resulting from this activity.

The site is considered relatively low priority with respect to the discharge of leachate. Based on the age, size and type of refuse disposed, the potential landfill gas generation has been estimated as low. The surrounding residential properties have the potential to act as gas collection points. Due predominately to the age of the site, it is considered relatively low priority with respect to the discharge of landfill gas (Wellington Regional Council 'Landfills in the Wellington Region' Technical Report).
Information received (MWH, 2005) shows that a soil contamination and leachate characteristic assessment was undertaken at the site. The cap thickness varies from 2.4m to 4.5m and was found to contain some minor amounts of waste. However, analysis of samples found concentrations of heavy metals and total petroleum hydrocarbons similar to background levels and below guideline values. Some waste refuse was also found in the fill material. Confirmation of leachate was obtained from a monitoring well on site. The leachate was found to contain high levels of chromium, lead and zinc.
April 2013: A recent review of the site information and the 2005 MWH report (doc#519543) indicates that the closed landfill and indicative leachate pathway is in the approximate area containing the scout hall, carpark and grassy playground area towards the boundary of but not including 198 Hanson St.

Beaurepaires (Ex ASC Flowers)
HUTT RD
This site has been used for the storage of hydrocarbons in underground tanks. The tanks have been removed in 1994 and soil from the walls and base of the tank pit were sampled and analysed. The results of the analysis showed the site is suitable for industrial/commercial use with respect to hydrocarbons.

LOT 1 DP 20504 LOT 3 DP 22303 LOT 1 DP 25743 - 3 M2 LEDGE IN COUNCIL AIR SPA CE
This site was previously used as a small anodising operation in the manufacture of housewares. Hazardous substances used include nitric acid, sulphuric acid, phosphoric acid, caustic soda and Alpo aluminium brightener. Stored quantities were less than 100 litres each. No detailed site investigation has been undertaken for this site and therefore the extent of contamination, if any, is unknown. The site is currently used for storage.

Ex Vacuum Oils
ARANUI ST
The site was part of a larger site used for the storage of hydrocarbons in aboveground tanks. Oil storage operations have been recorded on the site since the 1920's through until the site was subdivided in the 1960's. Greater Wellington holds no record of any environmental investigations undertaken on the site.
Information received (WCC 1974) shows that an underground storage tank was also installed on the site. It is unknown whether the tank remains and levels of contamination, if any, associated with the tank.

This site has been in operation as a clean-fill/demolition fill since 1978. There is a watercourse from the catchment piped under the landfill in a 900 mm pipe. Sampling undertaken in 1998 found that the levels of several metals exceeded guidelines for aquatic ecosystems - including lead, chromium and nickel (Land fills in the Wellington Region 1998). A site assessment in February 2006 notes a large proportion of the fill material was of non-cleanfill character including copper plumbing, lead flashing, reinforcing steel, timber, roof iron (even an old bath).

A site investigation was undertaken in Frank Kitts lagoon and the area around Taranaki Wharf. The sediments were found to contain heavy metal concentrations exceeding the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC and ARMCANZ, 2000) sediment guideline values. On the seaward side of the wharf Copper and Zinc exceeded the high trigger values for sediments. In Frank Kitts Lagoon Chromium, Copper, Lead and Zinc all exceeded the low trigger values for sediments.

Ex Levin & Company Woolstores
The site was used as a Levin & Company wool store from the early 1900's and were some of the largest in the country at the time. The drying and scouring processes which typically took place at these facilities involved the use of detergents and bleaching agents to removed oils, greases and pesticides from the fleeces.
Part of this site has been redeveloped (2005/6) as a motor vehicle sales yard. Oil tanks are to be installed for this purpose. A limited site investigation found that lead may potentially exceed the guideline values for industrial/commercial use. However given that the site is sealed this was not thought to pose a significant risk to the occupants of the site. An environmental management plan was constructed to address the potential discharges from the site during the redevelopment.

Information received (MWH report, August 2007) shows three underground storage tanks (USTs) containing diesel, tar and white spirits were removed from the site in April, 2006. Soil samples were analysed for Total Petroleum Hydrocarbon (TPH), and all samples complied with MfE guidelines. One other underground storage tank containing kerosene remains underground along with all pipe work. Previously, another underground storage tank containing waste oil was removed in 1994. Greater Wellington holds no information regarding the removal of this UST.
Information received (URS, 2011) shows that the asphalt plant has been demolished, and a new plant is to be built. All material from the demolition was recycled on site.

In September 2008, the GISMO polygon layer was altered to exclude the carpark area. After discussions with the Wellington City Council it was agreed that the carpark area is not associated with any contamination issues. It is believed this area is intended to be used for quarry activities in the future.

Masterton Landfill
MARTINBOROUGH MASTER
LANDFILL APPORTIONMENT
This site is the main operational landfill for the Masterton District serving the urban area. The site is close to the Ruamahanga River. Photos on file (from November 1994) appear to show large amounts of rubbish likely to be moving into the river from the landfill (as there is no boundary to prevent contamination). A Wellington Regional Council Department Technical Report into 'Landfills in the Wellington Region' (1998) states that leachate and landfill gas is adequately controlled by resource consent. It is however unknown if the issues of non-leachate waste entering the river have been addressed. The site is within an area of land classified as a 'Key Native Management Ecosystem Area'.

JACKSON ST
The site has previously been used for a dry cleaning operation. As part of this operation underground storage tanks were located on the site. A tank was removed from the site in August 2001.
The site was investigated in accordance with the Ministry for the Environments Contaminated Land Management Guidelines. The results of the site investigation show that hydrocarbons, organo-chlorines and heavy metals are present on the site at concentrations which may pose a risk to construction/maintenance workers and/or the occupants.
An assessment of the contamination was undertaken and potential remedial measures appropriate to the proposed land use were identified in the Environmental Management Plan. Providing the site was developed in accordance with the Environmental Management Plan, It could be considered suitable for the proposed use.
Information received (CRL Energy Ltd, December 2007) shows that two monitoring wells were installed in 2004, and subsequent monitoring of the groundwater has been undertaken since then. The report states that contaminants in the groundwater have now decreased to below relevant guideline levels. More information can be found in the consent file WGN040305.

This site has been used as landfill in the past and is currently used as the Kilbirnie Aquatic Centre and a sports field. The site is to be redeveloped and an investigation undertaken in 2003 identified a layer of soil at shallow depth which contained elevated levels of PAH (Polycyclic Aromatic Hydrocarbons). The amount of contaminated material is approximately 25m3. The layer of contaminated soil was to be removed (Jan 2006).
Information received (MWH, 2005) shows that a soil contamination and leachate characterisation project was undertaken at the site. Topsoil samples taken were found to contain slightly elevated concentrations of heavy metals in comparison to background values, but were below guideline values. No evidence of typical landfill refuse was found, but intrusive investigations were limited due to the hard ground. Leachate was found to be present in a monitoring well located on the site, which contained high concentrations of heavy metals, particularly arsenic, chromium, lead and zinc.
Information received (Tonkin & Taylor, 2007) shows that excavation and development of a new pool were undertaken at the site in 2006. A soil disposal validation report was produced to validate the disposal of the impacted soil. The amount of material removed from the site was approximately 600m3 or 1,220 tonnes. All the soil removed from site was disposed of at Southern Landfill.

SEC 2 SO 406882 SEC 3 SO 20946 - SCIENTIFIC AND HISTORIC RESERVE
Somes Island is currently administered by the Department of Conservation (DoC) and is accessible by private vessels or the East by West ferry operation.
Prior to being taken over by DoC, the island was used by the then Ministry of Agriculture and Fisheries (MAF) as a quarantine station until the early 1990's. The landfill was used by MAF to dispose of waste material that could not be treated by the islands oxidation ponds. Potential contents include out of date animal remedies, destroyed animals, ash from incinerator and general refuse.
The site of the landfill is located at the southern end of the island in a valley to the NE of the lighthouse. A stream flows through this valley in high rainfall and into a small bay. The overflow from the oxidation ponds also runs through this valley. The bay is a nesting spot for blue penguins.
Asbestos was identified at levels of concern in 2005 following the discovery of asbestos flakes from the roofs of buildings that were formerly part of the Quarantine Facility. Asbestos began to be removed from buildings in September 2005 and was completed in February 2006, however the Department of Conservation was concerned over the potential contamination of soils and a further investigation was conducted. This found four samples to be above the limit chosen (0.001%). In April of 2006 a remediation plan was proposed in which 5-10cm of contaminated soil was to be removed and contaminated areas clearly identified for the public. Activities such as mowing were restricted and further planting was recommended to reduce the dispersal of asbestos fibres. This work has yet to be undertaken (May 2006). All asbestos is unlikely to be removed and a long term risk management plan will be required.

Ex Bengal Street Tin Tip
CALCUTTA ST
This site was used as a tintip (accepted inorganic rubbish that could not be incinerated). The site is on a flat area approximately 10 x 10 m at the head of the valley. At the deepest point the fill area is 2-3 m deep. When the residential property on this site was constructed the foundation piles were driven deeper than normal due to the presence of loose fill. Under this fill was some 'general rubbish' such as corrugated iron etc, and then solid ground. A site inspection by Greater Wellington in 1997 found that during visual inspection of the site there were no indications of leachate. Given the age and the scale of the fill, it was thought unlikely that there were significant adverse effects occurring as a result of this site.

This site used to be a landfill in the early 1930s and is currently vacant. There is no information held on file at Greater Wellington regarding the operation, size or contents of this site. In the 1930s, there were complaints from the Khandallah Progressive Association about tipping. The City Corporation responded only that it was not a Corporation tip.

Miramar Park

LOT 2 DP 89983 - SUBJ TO & INT IN ROW
This site used to be a landfill and is currently used as a park for recreation. Surrounding land use includes residential, educational and commercial/industrial. The site is owned and maintained by the Wellington City Council.
There is no information held on file regarding the operation, size or contents of this site. Some of the houses in the area date back to the 1920s and this is used as a basis for estimating the age of the site in the same period. A Wellington Regional Council investigation into ?Landfills in the Wellington Region? (1998) estimated that potential gas generation and discharge was likely to be low. Leachate was thought likely to be to groundwater or the stormwater system.
Information received (URS report, March 2007) shows that a phase 2 investigation was undertaken at the site. The landfill cap was found to be in good condition, and on the basis of GPR results, the capping layer was interpreted as being approximately 1m thick. Soil samples taken from the landfill cap showed some elevated levels of Total Petroleum Hydrocarbon (TPH), cadmium, chromium and lead, with lead concentrations exceeding guideline values. Analysis of groundwater samples taken from two boreholes on the site indicate that while there are some levels of TPH and lead, leachate is unlikely to be present.
2012: A site management plan prepared by URS was received. The plan detailed management on proposed excavation work during the installation of 6 lighting towers at the Miramar Tennis Club.

Happy Valley Park

This site was previously a landfill. The current site use is recreation. A primary school is next door. The Happy Valley Stream flows along the western side of the site and any discharge is likely to enter this stream. The stream is likely to be affected by the discharge of surrounding landfills. The 1998 Wellington Regional Council Resource Investigations Department Technical Report 'Landfills in the Wellington Region' considered the site to be 'relatively low priority with respect to the discharge of leachate'. The potential landfill gas generation and discharge priority was estimated as medium.
December 2015: This site is currently under review.

This site has been used for the manufacture of bricks until the early 1970s. The site was redeveloped for residential use by demolition of the factory buildings and the deposition of fill to a maximum depth of approximately 15 metres. On this basis the brickworks site is considered relatively low priority due to the quantity of fill and the length of time since redevelopment took place. Historic comments within the SLUR database indicate that a fuel tank was installed in 1962, whether the tank remains on site or not is currently unknown. No further information as to whether contamination exists on the site is held by Greater Wellington.

This site is used for refuelling. There was evidence of ongoing secondary contamination from small amounts of fuel spilt on a number of occasions beneath the hydrants (1994 MW Environmental Management). Although the contaminated soil was removed it is not clear whether any soil samples were taken to verify that no contaminated soil remained. Contaminated soil was also found in 1996 while excavating for a pipe trench. Sampling for total petroleum hydrocarbons indicated that the contaminant was Kerosene (aviation fuel). A limited site investigation was undertaken by Pattle Delamore Partners Ltd however no assessment of the extent or source of the product was made. It is thought likely that the source was the fuel line. No further information is held by Greater Wellington as to whether the suspected leak in the pipeline has been fixed.
2012: Information was received that 2 avgas fuel storage tanks are planned to be removed possibly in October 2012.
2013: Information was received that 3 fuel storage tanks are now planned to be removed in April 2013.
2020: GHD undertook a Preliminary and Detailed site investigation in order to understand the level of contaminants within the Taxiway Bravo area. Contaminants were detected in all soil samples, but were below the adopted human halth assesment criteria, however groundwater has been confired to be contaminted with PFAS and heavy metals.

This site has been used for timber treatment. A copper-chrome-arsenic (CCA) boric pressure and antisapstain spray tunnel treatment system is used. Large quantities of boron, CCA and antisapstain are stored. Composite soil sampling undertaken in 1998 found that the levels of boron, chromium and copper detected exceeded the criteria for agricultural use but were within the guidelines for unpaved industrial sites. These findings have implications if the use of the site is changed in the future. Hydrocarbons have also been stored in bulk quantities. 20,000 litres of fuel is stored in an aboveground tank and 45,000 litres in an underground tank.
Information received (URS report, August 2007) shows an underground petroleum storage system (UPSS) consisting of one diesel storage tank, and associated dispenser and pipe work, were removed from the site in August, 2007. Soil samples were analysed for Total Petroleum Hydrocarbon (TPH). Some contained hydrocarbons identified as fresh diesel at concentrations above detection, although all samples complied with MfE guidelines, for commercial/industrial use and for the protection of groundwater quality.
The roadside drain has been included on SLUR due to discharge of untreated contaminated stormwater. Laboratory analyses of water samples in 2011 have identified high concentrations of timber treatment related chemicals and aluminium.

Newlands Park Auto Centre (Challenge)
NEWLANDS RD
This site has been used as a service station and mechanical workshop and stores hydrocarbons in bulk. A Montgomery Watson Environmental Effects Assessment Report was undertaken in June 1999 following the removal of underground storage tanks and decommissioning of the site by Caltex. Sampling of the soil at this time found that around the tank pit guidelines for maintenance workers and protection of groundwater were exceeded. Subsequently some contaminated soil was removed; however there was only limited opportunity to remove contaminated hotspots as the installation of new tanks overlapped with the decommissioning of the site. Sampling of petroleum hydrocarbons just beyond the boundary of the site in soil and groundwater were low and complied with relevant guidelines. A management plan was suggested to ensure that workers were protected from possible accumulation of hydrocarbon vapours near the ducts. Two underground storage tanks are currently on site (2004 Dangerous Goods Licence).
Information received (URS, 2010) shows that a remediation plan has been prepared for the site for the development of a supermarket.

Churton Park, Clean fill
MAULDETH TCE
A small section of the larger site has been used as a cleanfill; other areas of the site have been cut and filled to create building platforms. The cleanfilled area is designated to become a Wellington City Council reserve or playing fields. The cleanfill operator stated on 26 May 1997 'The fill material has mainly come from builders excavations. It also provided the resting place of clean fill material from the Wellington Regional Council Reservoir. The fill area had a manager who controlled the operation to see that only clean fill was placed however photos and notes on file show that non-cleanfill material has been added (scrap iron, asphalt and timber, refuse and organic material). It is reported that some contaminated fill from a Tahi Street residential development was used by the developers to fill in a gully at the top of Amesbury Ave. Materials were specifically declined if any contaminants were in evidence. The fill is now complete and has been sown for grassing. A visit to the site on 15 July 1997 showed small quantities of iron leachate coming from the toe of the fill. The site has been classified as No Identified Contamination. This is based on the close control of the clean-fill, however, no site investigations have been undertaken to support this.

GLENMORE ST
This medium sized landfill operated in the early 1930's. It is currently used for playing fields and as a general recreational area within the Botanical Gardens. Surrounding land uses are recreational, residential and commercial. Based on the age, size, and type of refuse disposed, the potential landfill gas generation has been estimated as low. Recreational buildings on the site have the potential to act as gas collection points however the site is considered relatively low priority with respect to the discharge of landfill gas.
Information received (MWH, 2005) shows that an investigation to determine soil contamination and leachate characteristics was undertaken at the site. Slightly elevated concentrations of heavy metals compared with typical background values were found in some of the four topsoil samples. A thin layer of black sand contained high arsenic, but appears to be an isolated hotspot. There was no evidence of typical landfill refuse, although the investigation was restricted to hand augers. No groundwater monitoring well was installed, hence it was not possible to test for the presence of leachate.
2024:Lady Norwood Rose Garden meets the MfE HAIL classification for category A10 – Persistent pesticide bulk storage or use, including sport turfs, market gardens, orchards, glass houses or spray sheds. Copper-based sprays were traditionally used on rose gardens, and decades of use may have concentrated this heavy metal in the topsoil, as it does not degrade. Evidence of the HAIL activity was confirmed from historic aerial photography.

Leachate is collected and discharged to the sewer. Analysis undertaken in 1989 found that sample results were within the acceptable limits 'Landfills in the Wellington Region' 1989. Further monitoring was undertaken in 1995. No further information is held by Greater Wellington. In 2004 the landfill occupied a large area south of Careys Gully Reserve however only a small portion was within the currently worked stage. The area provides important secondary ecological corridor.

Ex Ocean Oil Ltd
LOT 2 DP 61601 5 CARPARKS 62.5M2 ON ROAD RESERVE - NOT INCLUDED IN THE VALUA TION
During the 1970's and 80's reprocessing of waste oil, typically the removal of water from bunker oil was undertaken on the site. During this time a number of significant oil spills on the site were recorded. When the operation ceased the site was further developed and covered with a concrete pad.
A site investigation was undertaken in 1998 by Steven Young & Associates Limited. Three locations were identified for sampling, however soil was not recovered for chemical analysis. Below the concrete slab, there was a harfill layer and then a very hard layer which within 50mm was impenetrable. This material was assumed to have been natural rock of the hillside, which was cut down to create the building platform and then backfilled as the bese for the various concrete slabs.
Although, the investigation was limited, and there is potential for contamination to exist on site, the site is now entirely covered with a concrete pad preventing any exposure to these potential contaminants. Greater Wellington therefore considers that the site is suitable for an industrial/commercial use.

The site has been used for the production of transformers, reactors and other electrical power transmission and distribution equipment. Inspections of the site by council officers found poor site management practices in place, which had resulted in significant hydrocarbon contamination of the site surface. Limited site investigations were undertaken in 1996 and low concentration of hydrocarbons and PCB's were found to be present in the soil and the groundwater. These investigations were focused on the sites boundaries as there was no access to soils due to the site being almost completely sealed. The site has been assessed as suitable for continued commercial industrial use provided the sealed surfaces remains intact. Any redevelopment of the site which requires the floor slabs or sealed surface to be removed may need further investigation to ensure the suitability of the site for its intended use.

This site was used for the manufacturing of electric stoves and appliances. Contaminants of concern for this type of site include metal scrap and possible electrical wiring. The current building on site was redeveloped in 1986 and during construction there was significant excavation over the site area to allow the installation of a concrete slab foundation, and a 4-5 m cut into the hill at the rear (south) of the site. Given the nature of the contaminants and length of time since the site was operated as a manufacturing plant, the site is classified as having 'no identified contamination'.

2010: This site was a medium sized landfill used for general refuse. The site is considered relatively low priority with respect to the discharge of leachate. On the basis of the age, size and type of refuse disposed of at the site; potential gas generation has been estimated as low. There are residential dwellings surrounding the site that have the potential to act as gas collection points. Again, based predominantly on the age of the site, it is considered relatively low priority with respect to the discharge of landfill gas (WRC 'Landfills in the Wellington Region' Technical Report.
Information received (URS report, December 2006) shows that a soil contamination and leachate assessment was undertaken at the site. Due to the diffuse nature of refuse buried, limited information on the landfill sequence or depth could be gathered. Geophysical results indicate that there is evidence of waste beneath the Wellington Airport section of the landfill, carpark area of Rongotai College, and two discrete areas near Rongotai College. No soil samples exceeded guideline values for total petroleum hydrocarbons (TPH) or heavy metals. There is thought to be a low likelihood of leachate being present beneath the landfill.
2013: Information received from PDP Ltd (Site Assessment for Removal of Underground Petroleum Storage System). The site is Wellington Airport, Tirangi Road, Rongotai on Part Lot 1 DP78304 (Note that address on SLUR records as 28 Stewart Duff Dr). The report indicated that two avgas and jet fuel tanks with associated infrastructure were removed in April 2013. A small amount of soil was removed. The report indicated risk to human health from residual hydrocarbons was considered minimal.
2020: GHD prepared a DSI report for a minimal section in the top northeast, near coutts st for the Airport Fire Station development. Five locations of 11 samples in total were tested for asbestos, heavy metals and hydrocarbons. Asbestos was detected above BRANZ guidelines in two samples. Four locations had results above background concentrations for metals and TPH, but within the limits for commercial/industrial.

This site is an old saw mill which closed approximately 35 years ago (1998). A site visit in 1997 noted concrete foundations and rusty iron scrap remain on-site. There was no sign of any type of treatment vessel or spray tunnel. It is thought that the mill was used for native timbers only and that there were no timber treatment facilitates. However according to the current occupier pine was milled and there is a possibility that antisapstain treatment occurred. This has not been confirmed and there is no visual indication of it on-site (1998).
2022-John Gorrie’s sawmill’s only milled logs that did not require any form of treatment. From 1968-1976 there was no timber treatment occurring at this time in the Valley, as the only facility was located at Odlins in Petone, which was confirmed by Peter O’Flaherty, who knew John Gorrie and started in the local sawmilling industry in 1972.
"John Gorrie’s sawmill came originally from Akatarawa, it was the Mount Barton sawmill, 1963-67. It was erected with the help of well-known saw miller and millwright Alex Hussey. It was set up to mill the native timber of Ivan Whiteman’s property nearby and other contract sawmilling for local farmers, be it native logs, macrocarpa, redwood or douglas fir. Pine was only ever milled as boxing. Small local sawmills never lasted, because of the loss of availability of douglas fir, and radiata pine needed to be pressure treated and only Odlins at Petone had that facility" (Peter O’Flaherty, 2021).

A gully on the site has been used as a rubbish tip. It is not known what wastes were disposed of into the gully or who undertook the dumping. Our records indicate the waste materials have been capped, however, we hold no records detailing the capping materials, their thickness and whether these materials were compacted.
Analysis of the leachate discharging from the base of the tip was undertaken in 1997. The results showed elevated concentrations of Iron and Zinc. However, these concentrations were below the ANZECC Aquatic Guideline levels and therefore the leachate is not considered to be significantly contaminating the environment, although it should not be used for the watering of stock.
It is understood that the tip site is currently open space and does not pose a significant risk to the environment or the occupants of the site. However, should any more sensitive landuse - residential - be proposed for the site, then some investigative work could be required.

The site has been used for the production of concrete products such as pipes and sumps. This operation involved both chemical manufacture/formulation and concrete/cement admixtures. An above ground diesel tank (containing hydrocarbons) was on site (1998). It is unknown if this remains. In 1998 the site was occupied by a scrap metal merchant, they stored large quantities of both ferrous and non-ferrous metals. The non-ferrous metals are generally held within inside buildings. The ferrous metal was stored on open ground, however, it is proposed that this storage will now take place on a large concrete pad. . Greater Wellington is not aware of any environmental investigations having taken place on the site for this business. Therefore, the extent and concentration of any potential residual contamination is unknown.
Information was received for Caltex Seaview Diesel Stop, 47b Seaview Road, Seaview (Lot 2 DP 353068) from BD Group Design Ltd in December 2011. A URS report (Document #974021) dated 4 October 2011 presents information on decommissioning and removal of the petroleum storage and dispenser at 47b Seaview Road. The report indicates the assessment was carried out in accordance with the Ministry for the Environments "Guidelines for Assessing and managing Petroleum Hydrocarbon Contaminated Sites in New Zealand, 1999". Decommissioning works were undertaken on 23 September 2011. One 15,000 L diesel above ground storage tank and associated dispensers, fuel lines and interceptor were removed. No soil was removed.
Ten soil samples were submitted to Hill Laboratories for total petroleum hydrocarbons (TPH) analysis. The URS report indicates the soil test results complied with the corresponding Oil Industry Guidelines Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use.

Te Marua supplies treated water to the greater Wellington City area. Prior to construction of the Water Treatment Plant the site was rural land. It was completed in 1987 and from this time, until 1997, a large volume of sludge generated by the treatment process was spread out in drying beds located adjacent to the plant. In 1997 the sludge was no longer discharged to the land and the drying beds were rehabilitated. Investigations of the previously sludged area found the material was suitable as a growing medium and the soluble aluminium leachate (a potential contaminant) was comparable with that of normal soils (1997).
There are three bulk delivery areas for alum, hydrated lime and caustic soda all within bunded areas. During an inspection in 2001 a small amount of hydrated lime had spilt near the loading point and staining under the caustic soda area suggested a possible unrecorded spill.
The site has one underground and one aboveground storage tank containing hydrocarbons which are approximately 7 years old (2001). Recommendations made in the report included the installation of an observation well next to the underground storage tank and the use of an indicator (for example pH) to assess the presence of soluble chemicals in the containment bund storm-water prior to pumping (April 2001). It is understood that these issues have been addressed (November 2001).
A report by URS dated 21 October 2011 (doc #981505) indicated that decommissioning and removal of an underground petroleum storage system had occurred at the water treatment plant. The associated soil sampling and assessment was included in the report. The report indicated that decommissioning works were undertaken on 6 October 2011. One 30,000 L diesel underground storage tank and associated equipment were removed from the site. No soil was removed. The URS report indicated that soil samples removed for testing had soil test results that complied with the corresponding Oil Industry Guidelines Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use and the Protection of Groundwater Quality Criteria. The report indicated that a new underground storage tank had now been installed but was not owned or operated by Chevron.
June 2021: Wellington Water Limited (WWL) engaged GHD to undertake an environmental investigation of the Te Marua water treatment plant, this included a Preliminary Site Investigation and a Detailed Site Investigation. Storage tanks for fuel have occurred onsite, and six locations were tested for metals and metalloids, hydrocarbons and PAH. Most of the samples had concentrations of trace elements (arsenic, chromium, copper and nickel) above the Greater Wellington Regional Council (GWRC) background concentration range, and two samples had a concentration of total petroleum hydrocarbons (TPH) above the published GWRC background concentration range for C7-C36 hydrocarbons. All the soil samples submitted for analysis were below soil guidelines for commercial/industrial use.

It is unclear the age of the tank - it is possibly 70 years old. The site has also been used for the illegal dumping of rubbish (2004). Steps were taken by management to prevent this occurring again and the site to be cleared to its originally state of cleanfill (2004). A water sample taken in 2004 was within ' New Zealand Drinking Water Standards 2000'.
April 2022- ENGEO undertook a PSI; which outlined the fuel tanks were stored in the main Wellington Racing Club buildings, on racecource road.

Information received (URS 2006) shows that the underground petroleum storage system (UPSS) containing three underground storage tanks (USTs) was removed from the site. At the time the USTs were removed soil samples were taken to assess any residual contamination. The report states that all samples representing soil remaining on site, apart from one, complied with the relevant guidelines for an industrial/commercial land use. The sample which exceeded was taken from beneath the former northern dispenser, and contained concentrations of hydrocarbons that exceeded the guidelines for protection of maintenance and excavation workers, and volatilisation to indoor air for total xylenes. Further test pitting adjacent to this sample confirmed the impacted area contained within a small area. A site management plan (SMP) has been developed by URS (2006) to manage this impacted area.

One underground storage tank containing hydrocarbons was installed in 1985. The business had large, uncovered piles of bark chip, compost and soil on the premises. In 2004 Regional Public Health raised concerns that the site was a source of Legionella longbeachae bacteria. The site is next to a retirement village to which dust from the site is blown. Given the risk posed, Sutherland and Russell were sent an abatement notice in August 2004 to discontinue operation, until resource consent was gained. The outcome of this abatement notice is unknown.
A report by URS dated 2 September 2011 documented the decommissioning and removal of the underground petroleum storage system, associated soil sampling and a petroleum hydrocarbon residuals assessment. The assessment was carried out in accordance with the Ministry for the Environments "Guidelines for Assessing and managing Petroleum Hydrocarbon Contaminated Sites in New Zealand, 1999".
One 10,700 L diesel underground storage tank and associated equipment was removed. No soil was removed.
Seven of eight soil samples tested showed concentrations of TPH complied with the Oil Industry Guidelines Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use.
One sample (from beneath the dispenser) exceeded the Oil Industry Guidelines Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use for TPH in the C10 to C14 range. As this TPH range is a surrogate for PAH, the sample was tested for PAH. Results complied with the Oil Industry Guidelines Tier 1 Soil Acceptance Criteria for Commercial/Industrial Land Use
All results of testing indicated compliance with protection of groundwater quality criteria.

2007: This site has been used for timber treatment and the storage of underground tanks. Indiscriminate filling has also occurred at the rear of the site. Two underground storage tanks and 7m3 of contaminated soil was removed from the site in 1994. No tank report is held by Greater Wellington and it is unknown if any tanks remain.
A more detailed site investigation has been undertaken for the adjacent site for the timber treatment operation - See SN/04/060/02. The summary of the findings for this adjacent site are outlined below:
A report undertaken in 1996 found no evidence of contamination of the site by boron, lindane or other organochlorine pesticides. Pentachlorophenol was detected on site, at or about the guideline levels for agricultural land-use. Elevated levels of copper, chromium and arsenic were found in the two test pits dug. These pits were in the area formerly used for storing tanalised timber. The levels of arsenic exceeded all guideline values, the levels of copper exceed agricultural and residential use guidelines. There was a large quantity of derelict equipment on site.
The report recommended that either the soil is removed where unacceptable levels of contamination are present; or an appropriate capping layer is put in place over the contamination to prevent exposure for occupants of the site.
No confirmation has been received by Greater Wellington that either of these recommendations has been carried out (2006). It is unclear if similar contamination is on this lot also. For the purpose of the risk assessment it is assumed likely that a similar level of contamination has occurred as a result of the timber operation.
May 2013: Notification received that underground infrastructure including pipework associated with an underground storage tank for fuel (already removed circa 1994) will be removed during May 2013.
2014: Information received (#1412599) from Andrew Stewart Limited prepared for Kiln Street Developments Ltd (October, 2013) in support of redeveloping the site. The Detailed Site Investigation Report contains information confirming that the removal of pipework associated with the 2,500L underground storage tank (UST) was undertaken in September 2013.
2015: Site Validation Report (March 2015) by Andrew Stewart Limited received (#1497193). The report indicates that soil that had visible or olfactory evidence of being impacted by hydrocarbons was removed and disposed of at an approved landfill.
Contaminated soil was removed and validation sampling indicates that NES (2011) residential soil standards were met.

A site investigation in 1998 showed elevated concentrations of heavy metals (arsenic and zinc). While exceeding residential criteria, these results were below the industrial and commercial guidelines. Those considered were the 'Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand ' Draft for Consultation' (1997), the 'Australian and New Zealand Guidelines for the Assessment and Management of Contaminated Site's, ANZECC/NHMRC (1992) and 'Health Based Soil Investigation Levels' by Imray and Langley (1996).
Further investigation showed that the level of metal contamination reduces with depth and is below ANZECC investigation criteria and the subsurface samples. They are therefore thought not likely to pose an unacceptable risk to groundwater. A paper bag manufacturer (Unibag) currently occupies the site. No further remediation or investigation was deemed necessary provided the site is used for commercial/industrial use.

Tyre World (Ex Broadle Motors)
LOT 4 PT LOT 3 DP 3478-SO 30496
This site was a service station which has since been de-commissioned and used as for tyre storage. An underground waste oil tank was removed and replaced, however no details of when this occurred or if any contamination remained is known (1994 file notes). Two storage tank containing hydrocarbons (petrol and waste oil) were removed in 1997. No tank pull report or detailed site investigation is held by Greater Wellington. It is unknown if any tanks remain on site.

FERGUSSON DR
LOT 1 DP 32606 SUB TO & INT IN ROW DP 77422
The site was previously a service station and motor vehicle workshop. Fuel was stored on site in three underground fuel tanks. The site also stored waste oil in an underground tank. These tanks were removed from site in April 1997 and the site was investigated. The results of the investigation showed that with respect to the underground storage of hydrocarbons the site is suitable for a commercial/industrial use. However, no investigation was undertaken to investigate the potential for contamination resulting from the workshop activities.

This site was previously the site of Akatarawa Sawmill. The mill operated from 1947 until the early 1960's and was mostly native timber with some processing of pine from the early 1950's. There was no treatment undertaken at this site. There is groundwater bore for drinking water supply on this property. The bores are located upstream of the old mill site. This site has one underground storage tank (containing hydrocarbons) near the rehabilitation centre
The site was assessed by Greater Wellington as of very high priority for further investigation with groundwater and direct contact being the pathways of concern (1998). It is not known if this investigation was undertaken.

WHAKATIKI ST
The site has previously stored hydrocarbons in underground storage tanks, these tanks were removed in July 2003. For further information see URS Underground Petroleum Storage System Decommissioning report (OurSpace doc # CNMG-10-78). The residual contamination associated with the storage of hydrocarbons is considered acceptable for industrial/commercial use. However, no investigation has been undertaken to address the potential contamination from the other activities undertaken at the site. Alexander Contracting is listed in the 2006 phone book as undertaking drainage, asphalt and bitumen and general contracting.
It is understood that LOT 10 (114 Whakatiki St) is the access way, which also contained the USTs, and LOT 11 (116 Whakatiki St) contains the workshop building. Bitumen has only been stored on LOT 9 (112 Whakatiki St).

BP Silverstream
This site has been a service station at this location for at least 60 years (1994). A high score was obtained in a coarse screening of the site, due to the site being above the unconfined area of the main Hutt Aquifer (1998). A stream flows to the rear of the property. There are four underground storage tanks and one above ground storage tank on site. It is thought that the underground storage tanks are original but their condition is unknown. There was a spill from a truck in 2001 that resulted in storm-water contamination.
Information received (URS 2009) shows that following an accidental leak of diesel in March 2009, the underground storage tanks (USTs) were removed from the site. The report states that approximately 4,000 L of contaminated liquid was removed from the recovery sumps and tank pit 1, and a further 150 tonnes of contaminated soil was removed from the site. Further testing at the time of the UST removals found that were some isolated areas of soil contamination, and contamination present in the groundwater. It is understood that monitoring wells have been drilled on the site to determine the extent of groundwater contamination.
Information was received from AECOM (doc #983714). A report dated 28 October 2011 summarised findings of the additional environmental site assessment including tests in April 2011 and groundwater monitoring in 2011. Light non aqueous phase liquids were identified during April 2011 and groundwater monitoring. Groundwater monitoring down gradient of the source area reported minor concentrations of BTEX compounds at levels similar to previous investigations.
Information was received from AECOM (doc #1046788). A report dated 3 May 2012 summarised findings from a groundwater monitoring event in March 2012. The report indicated that residual light non aqueous phase liquid (LNAPL) was still present in soils in and down gradient of the tank area as evidenced by being present in two wells. Other wells had LNAPL concentrations below detection limit, suggesting that significant offsite discharge is unlikely. The report considered it unlikely that a significant risk is posed to onsite and offsite receptors but with the exception of workers conducting below ground works, soil removal etc in the near source vicinity.
2013: Information was received from URS (doc #1234502). A report dated July 2013 summarised findings from a groundwater monitoring event in April 2013. The report indicated that residual light non aqueous phase liquid (LNAPL) was still present in soils in the vicinity of former tank pits. The report indicated results were consistent with previous investigations.
2014: Information received (#1379887) URS report on groundwater monitoring May 2014. See report for further details.
November 2016: AECOM (previously URS) Groundwater Monitoring Event Report (August 2016) received. The report indicates that the 2016 results are consistent with those of previous groundwater monitoring events. For further information see the full report (CNMG-10-144).

SEC 796 HUTT DISTRICT
2007: This site was previously a sawmilling business and undertook antisaptian treatment of timber. Royds Consulting were commissioned to investigate the site in 1996. The report found no evidence of contamination of the site by boron, lindane or other organochlorine pesticides. Pentachlorophenol was detected on site, at or about the guideline levels for agricultural land-use. Elevated levels of copper, chromium and arsenic were found in the two test pits dug. These pits were in the area formerly used for storing tanalised timber. The levels of arsenic exceeded all guideline values, the levels of copper exceed agricultural and residential use guidelines. There was a large quantity of derelict equipment on site.
May 2013: Notification received that underground infrastructure including pipework associated with an underground storage tank for fuel (already removed circa 1994) will be removed during May 2013.
2014: Information received (#1412601) from Andrew Stewart Limited prepared for Kiln Street Developments Ltd (October, 2013) in support of redeveloping the site. Two underground storage tanks 1,000L (UST) were reported to have been on site in approximately 1998. An image revealed the location of one UST, however there was no evidence in 2013 of either the UST or hydrocarbon remnants. The location of the second UST was assumed and hydrocarbon staining was present on the unpaved surface in the vicinity, the UST was not present.
2015: Site Validation Report (March 2015) by Andrew Stewart Limited received (#1497193). The report indicates that all soil with contaminants present above applicable residential guideline values was removed and disposed of at an approved landfill. A 1 to 1.5m layer of cleanfill material has been placed across the entire property.
Contaminated soil was removed and validation sampling indicates that NES (2011) residential soil standards were met.

This site operated up to about 1970 milling Radiata and Douglas fir. According to the site manager no timber preservation was carried out on site. Anti-sapstain chemicals were used however, and Greater Wellington's records indicate the use of santabrite (PCP based) and borax (boron based). Soil sampling was undertaken by Greater Wellington in 2001.
The monitoring results indicate that there is some residual contamination within the soils in the immediate vicinity of the PCP spray/dip area. However the levels of PCP detected are considered to be acceptable for the low risk land-use of forestry/recreation, and boron levels in the samples were lower than the detection limit. The site is classified as a confirmed contaminated site. No remediation is thought to be required given the sites current land use and that contamination levels comply with current guidelines.

Te Marua Timber Company
MAYMORN RD
This site has been used for the treatment of timber and the storage of treated timber, chemicals and hydrocarbons. Limited site investigations have been undertaken on the site. These have shown elevated concentration of boron to be present on the site. However, no analysis has been undertaken to assess any potential contamination from the Copper, Chromium Arsenic treatment processes which have taken place on the site.

This site is currently used as a service station with the bulk storage of hydrocarbons. Two underground storage tanks and one waste oil tank were removed in 1995. No tank pull report is held by Greater Wellington and details of the replacement tanks are also unknown. No detailed site investigation has been undertaken and therefore the extent of contamination, if any, is unclear.

Caltex Trentham
LOT 2 DP 33741 INT IN ROW DP 78412
This site is a service station with the bulk storage of hydrocarbons. Five underground storage tanks (21 years old) were removed in 1994 and replaced with three underground storage tanks. No tank pull report is held by Greater Wellington. There are also several above ground storage tanks used to store waste oil and lubricants. A 'Take Charge' Assessment in 2003 noted some hydrocarbon staining on the forecourt and that three 210 litre drums (two identified as toxic) were dumped in the waste disposal area. All were in poor condition and 'prone to leakage'. It is unknown if any contamination has occurred. Environmental performance at the site was however classified as 'generally satisfactory'.
Information received (URS report, July 2008) shows that the Underground Petroleum Storage System, consisting of three underground storage tanks (USTs), dispensers and associated pipework were removed from the site in December 2007. The analysis of soil samples taken during the excavations found some localised areas of contamination beneath some of the former dispensers. In May 2008, approximately 25 tonnes of contaminated material was removed from the site and disposed of at an appropriate facility. Validation samples were taken and analysed, and the report states that they were found to comply with the appropriate guidelines. Greater Wellington has no information regarding possible contamination from the workshop area.

Caltex Upper Hutt / Mascar Motors
A service station and motor vehicle workshop are at this site. The service station has been in operation since the 1950's. Eight underground storage tanks and a compressor were removed in 1995. Greater Wellington holds no documentation concerning the past removal of tanks or any environmental sampling that may have been undertaken at the time to characterise potential soil and or/groundwater contamination. Currently there are three underground tanks of double skinned fibre glass construction on site. A Take Charge Assessment of the service station in 2003 found environmental performance at the time to be 'generally satisfactory'.

Mobil on Fergusson
A service station has been located on this site since the late 1960's. In 1995, Regional Council was informed that following pipe work testing, 600L of petrol could have been lost from the site during the previous two months. A site investigation was undertaken which showed elevated concentrations of hydrocarbons to be present in the soil. In October 1995, the old tanks and associated pipe work were removed and replaced with double skinned fibreglass tanks and fibreglass pipe work. In April 2005 the site was decommissioned and all the tanks removed. An investigation was undertaken to determine the extent and concentration of any residual contamination on the site. The results of the investigation showed that no significant hydrocarbon contamination was present on the site with respect to the underground storage of hydrocarbons. An assessment undertaken in 2005 to determine the potential contamination resulting from the use of the site as a motor vehicle workshop was also found to were below the "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand", Ministry for the Environment, 1999 for industrial landuse.

Mobil Silverstream
This site has been used as a service station since the early 1980's. There are four underground storage tanks containing hydrocarbons on site. There have been tank spillages in the past and, although the source of the spills have been repaired, it is unknown if the contaminated soil remains. A limited Detailed Site Investigation report (2016) is held on file which indicates that all soil samples collected were below the relevant guideline value for TPH and BTEX. Two groundwater samples collected had exceedances of relevant guideline values, one of benzene and the other of xylenes.
A Golder Associates investigation (March 2018) was completed between the removal of the former underground petroleum storage system (UPSS) and the installation of a new UPSS. Soil samples collected during this investigation did not contain concentrations of TPH, BTEX and PAH that exceeded the MfE (2011a) Tier 1 all pathways soil acceptance criteria for a commercial land use. Two soil samples collected beneath dispenser has parameters (benzene, (and/or) xylenes and naphthalene) that exceeded the MfE (2011a) Tier 1 soil acceptance criteria for the protection of groundwater quality. See full version of report (CNMG-10-326) for full details.

2007: This site is a service station with the bulk storage of hydrocarbons. Three underground storage tanks (petrol and diesel) and one above ground storage tank (LPG) was removed in 1992 and replaced with new tanks. No tank pull report or detailed site investigation is held by Greater Wellington and therefore it is unclear the extent of contamination, if any, that remains.
2014: A report received (doc#1307598) from PDP Ltd on Phase 2 site investigation to assess the presence and extent of any residual petroleum hydrocarbon impacted soil and groundwater at the site associated with a remote fill point. The report concluded that some exceedences may need to be addressed if land use change occurs.
2014: Information received (PDP Ltd report #1394247) on Z Trentham. The report was on additional groundwater monitoring. See report for further details.
2015: Information received (PDP Ltd report #1513664) on Z Trentham. The report detailed the removal of 4 underground petroleum storgae tanks and results of soil remediation/validation sampling. The report concluded that contaminated soil remaining on site posed an acceptably low health risk based on a conservative risk assessment against MfE guidelines (see full report #1513664 for guideline references and assessment criteria). Note - this report has been indicated to be commercially sensitive.

This site has been used for paint manufacture and has store hydrocarbons in bulk. The site produces mostly solvent based paint and a small proportion of water based product. Removal and replacement of underground storage facilities was undertaken in 1996. Three underground storage tanks were removed from the site in September 1996. Turpentine was found floating on the water prior to removal. Two of the three tanks, which contained turpentine, were in good condition however the unlined tank pit (containing xylol) had a number of holes. It is unclear where this contamination originated from. Elevated levels of total petroleum hydrocarbons and volatile organic compounds were found, soil was excavated and concentrations on re-sampling were below the Oil Industry guidelines.
A site inspection by Hutt City Council found a moderate Trade Waste Discharge (of high pH) resulting from the cleaning of vats had been occurring, unconsented, for a number of years and evidence of contamination around the fuel storage area (2005). Greater Wellington does not have any details of remediation.

Maidstone Park Nursery
This site had previously stored hydrocarbons in bulk. A significant spill of hydrocarbons occurred in December 1990 (6000 litres diesel) into the Hutt aquifer at Maidstone Park. A series of groundwater monitoring wells were installed and a product recovery well constructed. In 1993 water beneath the site did not meet the New Zealand Drinking Water Standards for pH, iron or manganese. However the contamination was thought to be well confined, given the low permeability of the ground and that there was no evidence of any contamination occurring away from the tank pit. An underground storage tank was removed in 1999. Greater Wellington does not hold a tank pull report or recent site investigation and it is unknown if any tanks or contamination remain.

This site was previously used as a transport depot. Three underground storage tanks were removed in December 1998. On removal one underground storage tank had holes and product was observed in the pit. Soil sampling undertaken at the time of the tank removal from this tank found that levels of TPH (Total Petroleum Hydrocarbons) were in excess of Tier 1 soil acceptance criteria for industrial/commercial site use. All other soil samples were within the Tier 1 soil acceptance criteria.
Groundwater in one monitoring well (sampled in both December 1998 and February 1999) had levels of BTEX (Benzene, Toulene, Ethylbenzene and Xylene) exceeding the Oil industry Guidelines criterion for the indoor inhalation exposure pathway of vapours on both occasions. Groundwater monitoring wells installed indicated that the contaminants were not, at that time, moving off site. Continued monitoring of the groundwater was recommended but Greater Wellington does not hold a copy of these results (if indeed it has been undertaken). Small quantities of hazardous substances (Class 2 and 3) are stored on site for the current business. It was recommended that further investigation be carried out should buildings or enclosed work spaces be proposed over this area.

This site has been filled with clean soil and rocks. Based on the low potential risk to the environment should non clean material be contained on the site, it was re-classified as one that had never been contaminated.

Clean Fill site - Haywards Hill
MT CECIL RD
This site was established in the early 1990's for the deposition of fill from the Haywards Hill substation redevelopment. The fill is of unknown depth and compaction. There has been some slumping in some parts of the land. Sampling undertaken in 1997 did not indicate any effects on the stream attributable to the fill site, however it was thought likely that water, visibly contaminated with iron oxide, came from a pipe flowing through the landfill. Further investigation was recommended to identify the source of the water flowing through the plastic pipe.
It is unknown if this has been undertaken.
The site was considered medium priority with respect to the discharge of leachate. The site is near to a 'Key Native Ecosystem Management Area - the Keith George Memorial Park. Landfill gas is not considered an issue.

2007: This site is a confirmed cleanfill that has allegedly received a variety of waste and general refuse in the past. The site has inappropriately disposed of waste material in the past (without consent). Groundwater sampling in 1995 indicated that both iron and cadmium exceeded criteria for the protection of aquatic ecosystems. When likely dilution after discharge of groundwater into the Mangaroa River is taken into account the figures are close to or meet the ANZECC guidelines.

Lamb Peters Print Ltd
LOT 2 DP 74812 INT IN R/W
This site has been used as for printing. Potential contaminants include metals, solvents, acids and alkalis. No further information is held by Greater Wellington for this site and therefore the extent of contamination, if any, is unknown.

Telecom Greytown
SEC 1 SO 36349 SEC 1 SO 33627 - GREYTOWN EXCHANGE - SITE NUMBER 10
According to notes on file this site has previously had an underground storage tank. However the 2002 Dangerous Goods Licence lists only a 250 litre aboveground tank. It is unknown if the underground tank has been removed. No further information is held for this site.

Will Holmes Ltd
LOT 1 DP 91046 LOT 6 PT LOT 2 DP 13450
This site has previously stored hydrocarbons in bulk quantities in underground storage tanks. These tanks were removed in 1999. No tank pull report or detailed site investigation is held by Greater Wellington Regional Council and therefore the extent of contamination, if any, is unknown.

WEST ST
Prior to 1953 this site was used as a Railways Good Shed. In 1953 the railway closed and the site was used by the Catchment Board as a depot and storage area. The depot is now used by the Wellington Regional Council (ex-Catchment Board) to store field equipment for river engineering projects, weed and pest control operations, and general labouring. Equipment includes chemicals, petrol, oil, metal beams and spray gear. A number of disused drums are stored on-site. This site is located across the road from an ex-gasworks site.
Two underground storage tanks containing petrol and diesel were on site. The tanks were removed in December 1994. Soil samples, when compared with current guidelines, would be 'highly likely to comply for an industrial site'. A Contaminated Sites Assessment by Montgomery and Watson in 2001 found elevated levels of benzene in the air. Possible sources are from the former underground storage tanks or groundwater contamination migrating from the adjacent gasworks site. Further sampling for pesticides and removal of contaminated soil was recommended. Results of sampling undertaken in 2002 for Volatile Organic Compounds were all non-detects. It is unknown if the contaminated soil has been removed.

Clean Fill Site, Fergusson Dr
FLAT 1 DP 80781 ON LOT 2 DP 18492 - HAVING 1/2SH IN 771 SQ M
There was originally a small creek on this site that was filled in at some stage. When fill was encountered during construction of the current buildings there were no indicators of non clean fill present. The site is considered to be a site that was never contaminated (1997).

Clean Fill site, Aniseed Gr
ANISEED GR
An area of the site has been identified as having been used as a cleanfill. Greater Wellington does not know what materials were placed on the site and therefore whether the site is suitable for its proposed use. Upper Hutt City Council has placed Memorandum of Encumbrance of the site requiring a Registered Engineers report prior to any construction on the affected areas of the site.

Sawdust Fill Pit, Whakatiki St
WHAKATIKI ST
LOT 5 DP 9051 FLAT 1 CARPORT 1 FLAT 2 GARAGE 2 DP 79866
The site was used as a landfill for sawdust during the 1940's and is currently used for residential purposes. A Wellington Regional Council technical report in 1998 considered the property relatively low priority with respect to the discharge of leachate. Landfill gas generation has been estimated as low. The residential dwellings on the site and neighbouring properties are potential gas collection points. This site was considered medium priority with respect to the discharge of landfill gas.

Precast Systems Ltd
Commercial concrete manufacture or commercial cement storage, Storage tanks or drums for fuel, chemicals or liquid waste
The site has been used for concrete product manufacturing since approximately 1962. A site audit undertaken on behalf of Greater Wellington did not identify any significant visible contamination. However, no sampling and analysis of the soils present on the site has been undertaken to confirm the presence or otherwise of residual contamination at the site. Drums containing hydrocarbons were stored on site.

Maymorn Rd, Tip Site
MAYMORN RD
Information held by Greater Wellington Regional Council indicates that this site is an old quarry and was used for the disposal of hardfill. A Wellington Regional Council form for 'Potentially Contaminated Site Description' dated 17 June 1994 for site K/9/4/18 at 1175 Maymorn Road indicates 'hard fill operation' and 'in an old quarry was a clean fill site'.
The site may potentially have included very small amounts of general refuse, although there is no direct evidence of this. A report (Wellington Regional Council 'Landfills in the Wellington Region' 1998, pages 193-194) indicates a risk ranking that there may be potential 'general refuse', however the quantity of potential 'general refuse' is very low. The report indicates that given the nature of the likely contaminants and the lack of identified discharge to the stream, the site is considered relatively low priority with respect to the discharge of leachate. As the site received predominantly cleanfill, landfill gas has not been considered an issue.
Information is also held on an adjacent related site in file SN/04/150/02.

Heretaunga Resthome/ Ex Silver Stream Tip Site
FIELD ST
This site is an old landfill. Notes on file for the type of tip are unclear and suggest that the site was used as a clean- fill and hardfill site up until at least 1998.
The site is currently used for residential purposes.

Ex Moonshine Road Landfill
MOONSHINE HILL RD
2007: This site operated as a landfill in the 1960s and it is likely that hazardous waste was deposited at this site. Monitoring of the site was undertaken in 1996 and 1997 over a period of 8-9 months. Sampling results indicated a discharge of leachate detectable at the downstream sampling points with iron, zinc and manganese present in elevated concentrations. Semivolatile organic compounds were not detected. The site is considered medium priority with respect to the discharge of leachate. Based on the age and size of the site, the potential landfill gas generation is estimated as medium, however there are no potential gas collection points within 300 metres of the site.

Village Motors
The site was a service station for over thirty five years. There were five underground storage tanks located on the site. In April 1999 the tanks were removed from the site and an investigation undertaken to determine the amount of residual contamination. The investigation found there was no significant contamination from the bulk storage of hydrocarbons. However, no investigation has been undertaken to determine whether any significant contamination is present resulting from the use of the site as a motor vehicle workshop.

Pitt J M Ltd Carriers
MOROA PLAIN RD
This site has stored hydrocarbons in bulk quantities as a transport operator. There is an underground storage tank containing 10,000 litres on site.
Information received (URS report, August 2007), shows the underground petroleum storage tank was removed from site in July, 2007. Soil samples were analysed for Total Petroleum Hydrocarbon (TPH). Some contained hydrocarbons in the weathered diesel range at concentrations above detection, although all samples complied with MfE guidelines, for commercial/industrial use and for the protection of groundwater quality.

R & B Motor Services
This site has previously operated as a service station. The underground storage tanks have been removed and a site investigation undertaken in 2002 found that soils sampled were compatible with Ministry for the Environment "Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand' 1999 for commercial/industrial use. However some elevated levels of hydrocarbons remain and should the site be redeveloped in the future for non-commercial/industrial use, it will be necessary to re-assess the risks posed by the residual hydrocarbons. An environmental management plan (held by South Wairarapa District Council) has been carried out for this site (2002).

Private Tip site
GILLESPIES RD
LOT 2 DP 52807 - SUBJ TO ROW
Extensive filling of clean-fill with small quantities of bitumen and reinforcing steel has taken place at this site. There are also several pieces of concrete creating a soak pit. A stream did run into the fill from the western side and flowed into the fill 6 metres from the edge. This water entered the Hutt River and was coloured rust red in 1997.
Samples were taken both upstream and downstream of the site. These samples were analysed for iron (Fe), chemical oxygen demand (COD), conductivity and pH. The results showed a significant increase in FE, COD, conductivity and acidity in the water.
However, when the site was visited in 1997, the stream entering the fill had been diverted around the fill (along the western side) and the quantity of seepage coming out the eastern side by the farm track was minimal.
Due to the fact that the site received predominantly inorganic fill, landfill gas has not been considered an issue.

Former Private Tip
This site is a former tip site and is currently used for residential and recreational purposes. Soil investigations carried out in the 1970's and 1980's indicate parts of the site contained undefined rubbish up to 3 metres on Lots 3 and 4. Sampling results indicate elevated levels of several metals in a storm-water drain/stream across Fergusson Drive from the site.
It is considered medium priority with respect to the discharge of leachate. Based on age, size and nature of refuse disposed. The residential properties on the site and neighbouring properties have the potential to act as gas collection points. This site is considered high priority with respect to the discharge of landfill gas (Filed 2003). Greater Wellington Regional Council has no record of any further investigation having been undertaken.

Ex Carter Holt Harvey, Main Rd
SEC 1 SO 36630 BLK IV TIFFIN SD
This site has been used for timber treatment. Greater Wellington records indicate that there were a number of chemical spills on the site and investigations undertaken have shown elevated levels of contaminants (copper-chrome-arsenic) present and polluting the nearby Waingawa River. Notes on file state that a diesel tank has been removed but that one remains. No tank pull report or site investigation is held by Greater Wellington and therefore the extent and degree of contamination is unknown.

ALEXANDER RD
General Motors started assembling vehicles on the site in 1965/6. As part of these operations, hydrocarbons and chemicals were stored and used at the site. Greater Wellington Regional Council holds a copy of a Phase 1 Assessment undertaken at the site in November 1997. The report details the removal of five underground storage tanks, PCBs and asbestos from the site. Asbestos does remain on site at identified locations, although it was not considered hazardous at the time the report was prepared. Our record show that three underground fuel storage tanks and a number of aboveground storage tanks remain on site.
Information received (Stu Clark & Associates Ltd 2008) shows that some remedial work has been undertaken at the site including the removal of asbestos and underground tanks. The report is however considered incomplete with regard to providing details on specific remediation sites, sample locations, sufficient validation testing, tank pull reports etc.

This site is an ex concrete works and the area of operation possibly also extended into neighbouring properties. Areas of the site were filled with weathered granular quarried rock on construction of the buildings for the steel company. Steel prefabrication and construction has also been undertaken on this site. The site is currently used by a bark company. Greater Wellington Regional Council has no record of any detailed site investigation been carried out, therefore the extent of the contamination, if any, is unknown.

Ex Upper Hutt Railway Yards
Railway yards including goods-handling yards, workshops, refuelling facilities or maintenance areas
The site was previously the Upper Hutt rail yards. The site was used for the maintenance and storage of locomotives and rolling stock.
A 2007 URS Limited Stockpile Sampling Investigation (ENAR-12-32217) is held on file for this site. The objective of this investigation was to confirm the material suitable to remain on site and that which required removal or management.

Ex Whitings Mill
SIERRA WAY
This site is an ex Timber Mill. There is no TPA registration for the mill but apparently there was a boric dip on the site in the 1970's. The exact details of treatment at this site are unknown. As pine was milled in the area the "boric" dip may actually have been an antisapstain of PCP buffered with boric.
The residential nature of the site warrants further research into the details of treatment in case PCP (antisapstain spray pentachlorophenol) was used (Wellington Regional Council Timber Treatment Sites Review 1998). It is unknown if this has occurred.

Ex Allied Engineering
Allied Engineering were on this site, however in 2003 the site was unoccupied. Greater Wellington Regional Council has no record of any site investigation being undertaken, therefore the extent of contamination, if any, is unknown.

Moonshine Rd Industrial Landfill
MOONSHINE HILL RD
PT LOT 1 DP 25988 LOT 1 DP 44987 PT SECS 211 212 HUTT DISTRICT
This site was previously a landfill and allegedly received a variety of industrial wastes including tyres and chemical manufacturing waste. The site is currently used for plantation forestry. The waste noted on site included a significant number of corroding drums and other scrap metal below the site. The bottom of the main fill area is at the upstream end of a swamp where there is a visible discharge of iron leachate. This was also seeping into the stream (1998)
This site was identified as high priority for further action in a 1998 Wellington Regional Council Report and an 8 month monitoring program was completed in June 1999. Preliminary recommendations from this were that no further action was required - the sampling indicated that there was very little impact on the stream from the landfill.

Allied Engineering
Motor vehicle workshops, Engineering workshops with metal fabrication
SHAKESPEARE AVE
This site is an ex Upper Hutt City Council works depot. The depot was located on this site from c.1952. A garage and workshop were on this site as well as a proposed oil store and petrol pump. Personal communications with the site owner (Mr Broeren, June 2008) suggests that an underground storage tank may have been present at the site, and has possibly been removed, but this can not be verified. The original site was subdivided into four lots, with lot 1 included on this register, as this is the lot which was occupied by the council depot. Allied Engineering now own and operate in lot 1 with a car wrecking business occupying some of the adjacent lots.
Greater Wellington Regional Council has no record of any detailed site investigation that has been undertaken. Therefore the presence of contamination, if any, from the historic and current land uses is unknown.

VBR Mechanical Workshop
BLENHEIM ST
2007: This site is used as a motor vehicle workshop. No underground storage tanks are on site. Potential contaminants include solvents metals and small amounts of hydrocarbons. No further information is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.

Eurocell Sawmilling Ltd
Wood treatment or preservation including the commercial use of anti-sapstain chemicals during milling, or bulk storage of treated timber outside, Commercial concrete manufacture or commercial cement storage
The site has previously been used for the production of concrete blocks and more recently the treatment of timber using boron and antisapstain. Greater Wellington holds no information regarding the nature and extent of any potential contamination at the site. A desk top investigation undertaken by Greater Wellington identified the potential for contaminants to be present on, and migrating off, the site.
Information received (URS report, 2009) shows that an environmental site assessment (ESA) has been undertaken at the site. As part of the ESA some soil samples were collected and analysed. While two separate samples contained elevated concentration of copper and arsenic, the report states that all results comply with relevant Ministry for the Environment guidelines for an industrial/commercial landuse. It is believed that the site will continue to be used for timber treatment.

Wedgelock Equipment Ltd
MONTGOMERY CRES
This site has been used for timber storage. The Wellington Regional Council is not aware of any site investigations having been undertaken at this site. The council engaged Montgomery Watson in 1998 to compile a history of all timber treatment sites in the region. They noted in this report that this site was never registered as a treatment site on the TPA/TPC lists and a site visit found no evidence of any timber treatment. It is considered unlikely that this has occurred.

Eagle Furniture
WILFORD ST
This site was used for timber milling. The site is not registered as a timber treatment site in the TPA/TPC lists and it is unlikely that any treatment took place. There is a possibility of PCP use for antisapstain. Top soil was removed from the site in order to level it out. It is not known where the soil was removed to. The surface covering where the timber would have been stored is now grass and gravel. The quality of the vegetation is average. There has been some hardfill brought into the site. No detailed site investigation is held by Greater Wellington.

Silverstream Railway clean fill
REYNOLDS BACH DR
2007: This site has been used for cleanfill (construction/demolition material) and is currently a railway museum. Fill was originally deposited close to the stream and subsequently required to be moved. A site inspection in 1994 noted one area of slight iron staining to the south of the fill area related to a stream culverted through part of the railway museum. It is unclear whether this was due to elevated iron in the soil or as a result of discharge from fill in the vicinity of the culvert. The site is considered relatively low priority with respect to the discharge of leachate. The site has not been sampled further given the absence of any indicators of a discharge of leachate to surface water.
2014: Information received (#1412600) from Andrew Stewart Limited prepared for Kiln Street Developments Ltd (October, 2013) in support of redeveloping the site.

This site is used as a diagnostic and agricultural research laboratory for animal diseases and it is surrounded by an associated farm used for research work. The types of chemicals stored and used in the research programmes include organochlorines, organophosphates, organonitrogen pesticides, arsenic acids, chromium and solvents. Quantities of the chemicals stored were thought to be less than 200 litres. A number of field trials were undertaken in the early 1970's using cobalt, copper, selenium and DDT. Pesticides, solvents, hydrocarbons and acids are currently stored on site. A former dumpsite for general rubbish was located on the site also. A landfill is also located adjacent to the site and may present landfill gas issues for this site in the future.
Between 1960 and 1992 hazardous wastes from laboratories were disposed of on site. The disposal area comprises a series of trenches (5m long, 1.5m wide, 1-2m deep). After 1992 a layer of 0.5m clean soil and demolition material was placed over the disposal area. No records were kept of what went into the trenches; however main contaminants are likely to have been solvents (principally toluene) chromium, arsenic acid and strychnine. Toluene scintillation fluid was the main source of radioactive material disposed of at this site.
In 2004 a Ground Contamination Assessment identified some contaminants in the soil. In general, concentrations of contaminants were not significantly high or unduly widespread. However there were some areas on site where chemical residues (elevated levels above industrial/commercial criteria for lead and arsenic and hydrocarbons) were identified. PCB's, solvents and pesticides were all below relevant guideline levels. These contaminants were generally within the research campus area and include the farm workshop, former sheep dips, former laboratory buildings, paddocks north of Alexander Road and a number of waste disposal sites. Results suggest that none of these areas, with the exception of the waste disposal site, appear to be large. Because of the geology of the soil (gravels) only shallows samples were collected.
Information received (Tonkin & Taylor, August 2008) contains a site validation report that documents the contamination remediation activities undertaken at the site. Previous investigations identified 15 specific areas where historical activities caused ground contamination. A remedial action plan (RAP) was developed and completed, which involved excavating and removing all impacted soil, and backfilling with clean fill. Approximately 7,000 tonnes of impacted soil was disposed of at landfill. Validation testing confirmed that soil with contamination in excess of guidelines specified in the RAP has been removed from the site, and that the objectives of the RAP have been met.
Information received from Tonkin and Taylor in a letter dated 8 October 2008 (doc#576314) stated that 'Validation testing confirmed that remaining soil met guidelines for residential site use'. The letter also included a copy of a letter from the Upper Hutt City Council dated 3 October 2008 accepting the validation report. The Tonkin and Taylor Site Validation Report (#1050600) dated August 2008 stated that validation testing confirms that soil with contamination in excess of the residential guidelines specified in the Remedial Action Plan has been removed.
December 2015: ENGEO advised that further remediation and testing was being undertaken and reports and results to be submitted to UHCC. An ENGEO site wide validation report (dated July 2016) is mentioned in the September 2016 report (below), however is not currently held on the GWRC SLUR file.
October 2016: Received a September 2016 ENGEO Validation of Remedial Works Report (CNMG-10-112) In April 2016 a waste pit containing material from the research facility was discovered in the middle of the site, immediately west of the 'horse-shoe' roadway.

Cleanfill Tip, Mangaroa Valley Road
MANGAROA VALLEY RD
2007: This privately owned site has been filled (at three locations) with illegally dumped material (car bodies, whiteware, domestic refuse, dead animals, demolition waste and other potentially hazardous material. It has been the subject of enforcement action by the Wellington Regional Council requiring removal of all non-cleanfill. The fill areas are near a wetland and above a stream and have discharged significant quantities of silt into this stream.
An inspection in 2001 notes that non clean filled material was still present on the property and clean fill was present on the middle dump site in such a way that it may enter water. The stream which runs along the property was discoloured possibly containing iron oxide. A further infringement notice was sent in January 2006 but was withdrawn in March 2006 after material was removed from the streambed. Ongoing monitoring is required and the site is considered to be of medium risk with regard to the discharge of leachate.
2013: A report was received dated 2001 examining the fill and its long-term stability.

NZ Army Mangaroa Storage Depot
FLUX RD
PART SECTION 134 HUTT DIST BLK II RIMUTAKA S D
2007: This site is occupied by the Defence Force and is currently used as a storage facility. It may also have been used as a decommissioning area after WWII. The site was also used for 'maintenance and manufacturing workshops' and an old concrete building on the north western boundary was used for chemical storage.
An underground storage tank containing hydrocarbons was removed in 1997. The tank was in 'excellent' condition and total petroleum hydrocarbons and volatile organic compounds levels were below detection levels. Therefore the site is classified as 'never contaminated' with regard to the underground storage tank.
The site remains classified as a 'site that has stored or used hazardous substances' because of the other activities undertaken. No detailed site investigation is held by Greater Wellington and therefore the extent of contamination, if any, is unknown. There is a domestic water supply bore on site.
2013: Current GIS information on SLUR indicates the parcel of land on SLUR relates to number 36 and 54 Flux Road rather than other property information in SLUR indicating 48 Flux Road. The GWRC central file storage system indicates the property is called 36 Flux Rd. A review of the file including the Montgomery Watson report on the Soil Test Investigation dated May 1997 indicates there were houses to the north east of the site in 1997 (listed as numbers 42, 44 and 48 Flux Rd in 2013). The Montgomery Watson report was for soil sampling in the vicinity of the previous underground fuel tank in the middle of the site. The report concluded there was no evidence of petroleum hydrocarbon impact on soils in the tank pit.

Fish-N-Food
This site was used as a drycleaners until 1997. Greater Wellington Regional Council has no record of any detailed site investigation having taken place. It is now operated as fish shop. The back yard is concreted and contains a couple of old sumps thought to be associated with the drycleaners. Possible contaminants associated with drycleaners in general include trichloroethylene, 1,1,1 -trichloroethane, perchloroethylene, carbon tetrachloride and hydrocarbons.

The main site was owned by William Cook and Sons Limited from 1929 until 1958, when Fletcher Hardware Company Limited bought the site. It is unknown what processes took place on the site during this period. Then Todd Motors bought the lots comprising the site between 1961 and 1974 and used it for the assembly of motor vehicles. In 1974, the site was leased, and subsequently sold to Feltex, who used it for the production of underlay and footwear. Until the 1960's, the three lots bordering on the Hutt Road were residential dwellings, since 1994 they have been used for the retail of hardware, processed timber and laminate boarding. The current owners acquired the site in 1994.
In 1993, Feltex commissioned Richard Oliver International Pty Ltd to undertake an environmental assessment of the site and their operations. The report highlighted that there were three underground storage tanks on the site, two of these tanks were removed prior to the site inspection and the third storing base oil was removed from the site in 1994. A tank pull report for the third tank indicated that concentrations of hydrocarbon were below the residential and agricultural guideline values. Greater Wellington holds no record of any investigation being undertaken following the removal of the first two tanks. The report also identified a number of other issues, including a discharge of oil to land, which were remediated or acceptably managed.
The main site - Lot 1 DP 23022, Lot 1 DP 3025 & Lot 14 PT Lots 1 & 18 DP1819 - has had a long industrial past, which has involved a number of activities recorded on the Ministry for the Environment's (MfEs) Hazardous Activities or Industries List. The lots on the Hutt Road - Lot 2 DP 23022 & Pt Sec 3 Hutt District - have only been part of the industrial site since the early 1960's and no significantly contaminative uses have taken place on these lots. Therefore, it is considered unlikely that any significant contamination would be present on these lots. However, this could only be confirmed by an intrusive site investigation in accordance with the MfEs Contaminated Land Management Guidelines.

The site was previously owned by Feltex and opened c.1941. Substances stored on site include; dye, sable, latex, oil and acetic acid, detergents, peroxide, synthetic pyrethroides, asodium sulphite, peroxides, perchlonethylene and ethylene glycol. A Latex spill from a drum occurred in 1985 and was washed into a stormwater drain. Feltex were granted consent in 1974 to discharge "residues and washwater from dye house processing, up to 240,000 gallons daily into the Waiwhetu Stream" and "boiler blow-down and condensate loss up to 10,000 gallons daily into the Waiwhetu Stream. In 1994 a storage tank (empty) remained on site, and one tank had been removed. It is unclear where these tanks were located. A tank removal report is not available.

Information received (Tonkin & Taylor, October 2006) shows that an assessment of potential for ground contamination was undertaken on the site in September 2006. The assessment found potential for ground contamination from a number of sources including: historical paint manufacture and fish rendering related activities, underground storage tanks and above ground oil storage. In addition to potential ground contamination, the study identified the presence of asbestos containing materials in the roof of the factory. Further information shows that the asbestos roof has been removed and replaced.
A preliminary soil and groundwater investigation was received (Tonkin & Taylor, May 2007). Twelve soil samples and one groundwater sample were collected and analysed for volatile organic compounds (VOCs) and heavy metals. Evidence of soil contamination was observed at three out of the four sample locations, in the form of solvent odour and black-oily stains of gravel. The report states that the analysis of soil samples found no heavy metals or VOCs detected at levels that exceeded health-based guidelines. VOCs in one sample exceeded guidelines for protection of groundwater. The report states that no substantial soil contamination was detected, however, due to the limited scope, it is possible that there are contaminated soils on site which were not captured in this investigation.
Further information received (Tonkin & Taylor, December 2007) shows that six underground storage tanks (UST's) believed to have contained solvents were removed from the site in November 2007. The report states that concentrations of VOCs and metals in soil at the base and side of the tank pit met relevant guidelines for commercial/industrial land use and protection of groundwater. The tank pit was backfilled with imported material obtained from a quarry.

No detailed site assessment has been undertaken.

27 Western Hutt Road (27 Pito-One Road)
Motor vehicle workshops, Transport depots or yards including areas used for refuelling or the bulk storage of hazardous substances
WESTERN HUTT RD
This site was occupied by a motor vehicle manufacturing company from approximately 1949 until the late 1970’s or early 1980’s it was then changed to a transport depot. The transport depot was on site until 2011 when the site became a car yard.
These activities meet the Ministry for the Environment Hazardous Activity and Industry List classification for the following categories: Category F - Vehicle refuelling, service and repair, Activity 8 - Transport depots or yards including areas used for refuelling or the bulk storage of hazardous substances and Category F - Vehicle refuelling, service and repair, Activity 4 - Motor vehicle workshops.
ENGEO undertook a Preliminary Site Investigation in November 2015 (CNMG-9-100) under NESCS requirements as a result of the redevelopment of the site being proposed. No further investigations are held on file for this site. The extent of contamination, if any, is currently unknown.

Cambridge Automotive Ltd
The site has previously been used as a service station and a motor vehicle workshop. The underground fuel storage system was removed in February 2005. An investigation was undertaken to determine the extent and nature of any residual contamination associated with the storage of fuel. The investigation indicated that although there was residual contamination on site, the site was with respect to the hydrocarbon contamination suitable for commercial/industrial use. The site investigation did not investigate any potential contamination resulting from the workshop activities.

The site has been used for the storage of chemicals. Greater Wellington holds no record of any environmental investigations having taken place.

Wingate Service Station (1987) Ltd
EASTERN HUTT RD
Wingate Service Station (1987) Ltd was still at this site in 2006. A small leakage of hydrocarbons from an underground storage tank is known to have occurred (recorded in 1994). The Take Charge Assessment indicates that two underground fuel storage tanks were removed in 1992, no tank pull reports or detailed site assessments are held on file for this site. The number of storage tanks on site is currently unknown.

CONNOLLY ST
LOT 2 DP 87322 1/10 SHARE LOT 6 DP 3286 -OUTSIDE STOP BANK-
The former Certified Concrete Ltd Plant operated from pre-1940 till 1990 site is now a grassed park area. Two separate manufacturing operations were run - a Stresscrete plant and a Readymix plant. Spillages of additives which were added to the concrete occasionally occurred. A dilute hydrochloric acid solution was used to clean trucks and the mixing pool. Wash water and slurry from this process was dumped into a pit. Underground storage tanks were on site but these were removed 10 years ago by Europa (now BP Oil). BP oil holds no record of this tank pull and it is unlikely that any sampling occurred. The site was levelled by the Wellington Regional Council. Independent soil sampling was undertaken in 2001, and results were analysed for petroleum hydrocarbons, BTEX, and PAH. Hydrocarbons were found in very low levels; however they did not exceed guidelines for residential or industrial use. There was no evidence of contamination associated with alkali waste.

Avalon Service Centre Ltd
TAITA DR
Ex Shell service station which is now a mechanical workshop (Avalon Service Centre). Approximately 76,000 litres of petrol leaked from an underground storage tank in 1988. The tank was corroded, and it appeared that the leak had been running for about 3 months before it was detected. GCNZ prepared an estimate of plume direction and likely contamination concentrations. They estimated that it would take about 3.5 years for any residential benzene to reach Copeland Street. This was very near the site of artesian water abstraction by the Wellington Regional Council. A product recovery mechanism was installed and product was recovered. Substantial amounts of product remain to be recovered (1992).
While the tank was immediately drained of petrol and replaced and product recovered from the groundwater, it is unknown the extent of soil remediation, if any.
An underground storage tank was removed mid 1996 with no evidence of contamination according to the Hutt City Council. No detailed site investigation has been undertaken with regard to the sites current use.

This site was previously used for the manufacture of bitumen coatings, PVC plastisols, concrete admixtures, cleaning compounds and powder fertilisers. Asbestos had been used for manufacturing purposes until some 15 years ago. Other hazardous materials used include chlorinated solvents, acids, alkalis and some heavy metals. Three underground storage tanks were on site which contained petroleum hydrocarbon solvents.
An environmental site assessment undertaken in 1992 found elevated levels of hydrocarbons in several areas on the site, generally associated with underground storage tanks (subsequently removed). One sample showed slightly elevated levels of PCP's.
Asbestos decontamination of automotive and construction buildings was undertaken, and other contaminated soils removed from both the foundation area of the construction building and the former drum storage area. Other asbestos areas were stabilised. Low levels of contamination remain in shallow soils, however the site was deemed to be remediated to ' a level consistent with existing land-uses in the area'.
The site is currently a truck storage yard with a couple of workshops. No site investigation has been undertaken for this use.

HUMPHRIES ST
Bulk storage of hydrocarbons has previously taken place on the site in underground storage facilities. Three underground storage tanks were removed in June 1997. The site was assessed for hydrocarbon contamination resulting from the underground storage of the hydrocarbons and found to comply with industrial/commercial guideline criteria. However, we are not aware of any assessments of potential for contamination resulting from the workshop and transport depot activities.

Rimutaka Summit Yard
The Rimutaka Summit Yard was used by the railways until the 1950s. The area was then planted in forest and logged in 2001. The Wellington Regional Council decided to develop the area for public use. During initial landscaping work, ash, clinker and metal scraps were found on the site. These contaminated materials were believed to have resulted from the railways' activities formerly undertaken at the site. They may also include waste from the old railways' workshop in the Hutt Valley.
Analysis of samples taken from the site showed high concentration of aluminium, manganese, lead, copper, zinc and iron. Blue asbestos was also detected. It was thought a high probability that these metals were being leached and entering the stream flowing through the site. The stream was diverted and the site was remediated through the removal and capping of contaminated materials.

This site has stored hydrocarbons in bulk quantities as a transport operator. Two underground storage tank were on site but have been removed. There is currently an aboveground storage tank on site (5000 litres). No tank pull report or detailed site investigation is held by Greater Wellington and therefore the extent of contamination, if any, is unknown.

East St, Transport Yard
EAST ST
2013: This site has been used as a contractor's yard, from prior to 1966 to 2009 which involved the storage of some chemicals and fertiliser including an above ground storage tank containing diesel. Information received (Tonkin & Taylor, 2010 doc #849882 and #1192702) shows that a ground contamination assessment has been undertaken at the site. The Tonkin & Taylor, 2010 indicated that in 2009 a diesel tank, hardstand and sheds were removed and a layer of topsoil was placed on the site. Several test pits were excavated and soil was tested to assess any residual contamination. The Tonkin & Taylor report states that results from the soil tests show no residual contamination and the site is suitable for a residential land use.
