RNZAF Base Woodbourne PFAS Investigation: Comprehensive site investigation report (Woodbourne CSIR) - December 2019
The New Zealand Defence Force has been investigating the contamination of ground, water and biota associated with the use and storage of products containing PFAS at Base Woodbourne. Investigations have identified PFAS in soil and water on the base, and in water in the surrounding environment and neighbouring properties. A three-dimensional groundwater flow and transport model was developed to assist with estimating how the plume may evolve in the future. Modelling the plume behaviour has shown that the plume is currently in a stable state and the spatial extent of the plume is likely to remain relatively constant for the foreseeable future. NZDF is part of the All of Government PFAS Programme and has been working closely with the Marlborough District Council and other agencies who have received a copy of this report.

EPA seeking submissions on proposed amendments to the Fire Fighting Chemicals Group Standard 2017
The closing date for submissions has been extended by two weeks from Monday 2 December 2019 to Monday 16 December 2019. This is to allow more time for interested parties to make submissions on the proposed amendments.
The proposed amendments to the Fire Fighting Chemicals Group Standard are intended to decrease the environmental and public health risks due to firefighting foams. The proposed amendments will phase out firefighting foams containing PFAS, provide for the disposal of PFAS firefighting foams and PFAS waste products, and set restrictions on the use of PFAS firefighting foams during the 5-year phase out period.
The consultation document and information on the proposed amendments can be found on the EPA website. Submissions should be made to the EPA by 5pm on Monday 16 December 2019.

Waitematā Harbour comprehensive site investigation report complete
The New Zealand Defence Force has been investigating the accumulation of PFAS in biota and sediment in the Waitematā Harbour relating to the historical use and storage of PFAS-containing products at the HMNZS Devonport Naval Base and the Royal New Zealand Air Force Base Auckland (Whenuapai). The Waitematā Harbour Comprehensive Site Investigation Report summarises the results previous investigations in these areas. This report states that PFAS compounds are very common in urban environments, and there are likely to be many sources of PFAS to the Waitematā Harbour. Limited sampling has confirmed the presence of PFAS in biota and sediment adjacent to the firefighting training areas as New Zealand Defence Force sites. With the limited information available it is not possible to fully describe the extent, and effects, of PFAS in marine biota within the harbour. NZDF is working closely with Auckland Council and other agencies. Auckland Council have received a copy of this report.

PFAS investigation, response and funding guidance released
This guide outlines the process of gathering information to make decisions about investigating, managing and remediating sites in New Zealand contaminated with PFAS. It provides an overview of the duties, functions and responsibilities of councils and landowners. The guide is aimed at contaminated land practitioners, regulatory authorities, and owners or occupiers of sites where PFAS are present or suspected in the water or soil.
Update 4 April 2019
Report of EPA investigation into firefighting foams released
The Environmental Protection Authority (EPA) has released a report on its findings on a national investigation into firefighting foams containing PFOS.
The investigation found stores of firefighting foams containing the banned substance PFOS (perfluorooctane sulphonate) at several sites across New Zealand. At all sites where the banned foam was identified, including those which are not yet fully compliant, the foam has been secured within equipment, and secured against use. The foam is not accessible to the public and there is no public risk.
PFOS foams were excluded from the Firefighting Chemicals Group Standard in 2006, meaning they could no longer be imported into New Zealand. In 2011, all PFOS products were completely banned and strict controls were set to manage their storage and disposal.
The aim of the EPA investigation was to discover whether PFOS-containing foams had been imported, manufactured, used, stored, or disposed of in New Zealand in contravention of Hazardous Substances and New Organisms Act 1996 (HSNO) requirements, and the extent of these activities. The EPA sought to ensure any non-compliant foam was removed and disposed of safely; that any places or equipment in contact with the foam were decontaminated, and that clean-up materials were appropriately disposed of.
More information is available in the full report on the EPA website.
Update 31 January 2019
Devonport detailed site report completed
NZDF has undertaken comprehensive testing of Devonport Naval Base and nearby Ngataringa Bay over a period of time to determine the extent of any potential contamination from the historic use of firefighting foam containing PFAS at Devonport Naval Base. The results give us a good overall picture. The results show there is PFAS below guidelines in finfish and above guidelines in some shellfish. Finfish are exposed to PFAS elsewhere in the harbour and shellfish are exposed to water moving in and out of the bay. PFAS was also found in samples taken from a control site at Hellyers Creek in the upper Waitemata Harbour, far from Devonport Naval Base, which indicates there are other sources of PFAS entering the harbour. NZDF is part of the All of Government PFAS programme and has been working closely with Auckland Council and other agencies. All results have been passed to Auckland Council. Local drinking water comes from Auckland’s reticulated supply and is not affected.

Update 30 November 2018
A literature review has been completed to look at the impacts of PFAS on ecosystems. This is a first step in understanding the effects of PFAS compounds on the New Zealand environment beyond a direct or indirect human health perspective. It is a review of globally available research around potential impacts of PFAS compounds on ecosystems and considers the application of the research in a New Zealand context. The paper also outlines data gaps and provides recommendations on the scope of research possibilities within New Zealand.

Update 9 November 2018
Latest PFAS testing results reported to Ohakea landowners
Results of fourth stage testing for the PFAS compounds PFOA, PFOS and PFHxS have been reported back to landowners near RNZAF Base Ohakea. The testing is to investigate the extent of PFAS compounds in the environment around the base.
These results provide the most recent update to the broad New Zealand Defence Force testing programme and follow three previous rounds of testing carried out in December 2017, February-March 2018 and May 2018. This fourth round of testing was conducted in September, and included groundwater and surface water sampling.
The number of samples that detected PFAS compounds has not significantly changed from the previous rounds of testing. Of the 65 groundwater samples tested, 14 samples exceeded the interim guidance levels for drinking water for the sum total of PFOA and PFHxS, similar to previous testing rounds. Work is now underway to analyse the data collected during the seasonal sampling programme to pull together a more detailed picture of where PFAS is in the environment downslope of Base Ohakea, and how it might change in the future.
Alternative drinking water supplies have been offered to people at all affected properties.
The Ministry for the Environment (MfE) is leading the All of Government PFAS Programme. Claire Richardson, MfE’s Chief Operating Officer, said the advice of health officials remains that there is no acute health risk, but a precautionary approach is being taken because the long term effects are uncertain.
“The Ministry of Health says the findings from the fourth stage testing confirm their advice following the previous three rounds of sampling that there is not a significant public health risk.
“Currently there is no consistent evidence that environmental exposures at the low levels New Zealanders are generally exposed to will cause harmful health effects.”
Claire Richardson said all affected households in Ohakea had been offered alternative water supplies as a precautionary measure when testing was done.
“As with the previous rounds, we are working directly with those affected around Ohakea, to provide them with advice and support tailored to their individual needs.”
The Ministry for Primary Industries (MPI) has reviewed the latest results and their advice also remains the same.
“MPI says there is no risk to the general food supply from produce grown on the tested properties.
“MPI will continue to monitor any published research on PFAS to ensure our advice is correct, and update residents as appropriate.”
Claire Richardson said PFAS was one of a number of emerging contaminants that is being grappled with around the world, and New Zealand is working proactively to identify potentially contaminated sites.
“Our priority is working with affected communities,” she said.

Latest PFAS testing results reported to Woodbourne landowners
Results of fourth stage testing for the PFAS compounds PFOA, PFOS and PFHxS have been reported back to landowners near RNZAF Base Woodbourne. This testing is to investigate the extent of PFAS compounds in the environment around the base.
These results provide the most recent update to the broad New Zealand Defence Force testing programme and follow three previous rounds of testing carried out in December 2017, February-March 2018 and May 2018. This fourth round of testing was conducted in September, and included groundwater and surface water sampling.
The number of samples that detected PFAS compounds has not significantly changed from the previous rounds of testing. Of the 112 groundwater samples collected, two were found to exceed the interim guidance levels for drinking water. Both properties have previously exceeded the guidance level, and have had an alternative water supply provided. Of the surface water samples collected, a similar percentage of detectable levels of PFOA and PFHxS were reported, however no landowners or occupants have indicated that these sites are used for stock watering or irrigation. Work is now proposed to analyse the data collected during the seasonal sampling programme to pull together a more detailed picture of where PFAS is in the environment downslope of Base Woodbourne, and how it might change in the future.

Update 31 October 2018
New Zealand Food Safety report
A Ministry for Primary Industries survey of 12 food groups for Per- and Poly-Fluorinated Alkyl Sustances (PFAS) has found no dietary concerns for New Zealanders from the emerging contaminants.
The survey, which included vegetables, dairy products, meats, takeaway food and seafood, was carried out on samples collected as part of the 2016 New Zealand Total Diet Study programme. Surveys or routine monitoring of PFAS related chemicals have not been carried out before, although there has been limited monitoring of food and biota around some site investigations.
To establish occurrence and baselines in the New Zealand diet, 96 food samples were tested for 29 different PFAS compounds. All the food samples were prepared using standard cooking practices to the form in which they would usually be consumed, eg, dry frying was undertaken in non-stick frypans. The levels of potential exposure to New Zealand consumers have been estimated and all are well within the health based guidance value, and therefore are not considered to present a dietary concern.
Only one sample of beef steak had a positive detection, for the chemical PFHxA, at a level that doesn’t present a dietary risk. No detections were made of the three PFAS compounds of current regulatory interest (PFOS, PFOA and PFHxS). While the source of the detected PFHxA is unknown, one possibility is migration from food packaging or from cooking utensils, as it can be found as a breakdown product of stain- and grease-proof coatings on food packaging and household products.
Update 19 October 2018
Results from Whenuapai testing
Test results provided to Auckland Council by the New Zealand Defence Force (NZDF) show that PFAS compounds have been detected in some areas surrounding the Whenuapai Air Base, but no drinking water is affected.
PFAS compounds are not present in deep bores of between 200-300 metres in depth that might be used as local water sources. Drinking water in the area comes from the town supply and is not affected.
NZDF tested ground water (bores) and surface water at 12 properties neighbouring the base between 26 July and 30 August 2018.
The results show:
NZDF consultants are undertaking further analysis of sediment and biota results. Auckland Council is waiting to receive this additional analysis, together with the results of the Defence Force’s testing at Ngataringa Bay in Devonport, which is expected before the end of the year.
Results have been delivered to the property owners where testing was undertaken. Government agencies are offering advice to these property owners as required.
Update 8 October 2018
PFAS Summit in Sydney
Two members of the All of Government PFAS Programme attended a PFAS Summit in Sydney last week. The Summit, organised by the Australasian Land and Groundwater Association, brought together around 300 people directly involved in responding to PFAS contamination.
Professor Nicholas Buckley, chair of the Australian Government’s Expert Health Panel on PFAS, talked to the Panel’s recent report, which concluded that the evidence for PFAS exposure and links to health effects is weak and inconsistent. That said, Patricia Reyes, a speaker from the United States Interstate Technology and Regulatory Council, told the Summit that PFAS has been one of the biggest environmental issues in the US for the last three years.
All of Government representatives at the Summit said the PFAS contamination issues we face in New Zealand are dwarfed by the scope and scale of the Defence Force sites in Australia and the contamination from PFAS manufacturing sites in the US. However, we share the same issues around research and understanding of PFAS, managing waste streams and having the appropriate regulatory and institutional arrangements in place.
The Summit confirmed that New Zealand’s approach to PFAS to date has been consistent and keeping pace with other agencies worldwide.
Update 11 September 2018
Fourth round of testing has begun near Ohakea and Woodbourne
The New Zealand Defence Force has begun its fourth round of testing for PFAS compounds at properties near Ohakea and Woodbourne Air Bases.
Landowners and residents have been contacted and arrangements made for samples to be collected. This round of testing will mean that NZDF will have completed the seasonal testing needed to determine the possible effect of changing weather patterns on levels of PFAS compounds.
Properties at Woodbourne where PFAS has not been detected in the previous three rounds do not need to be tested again. NZDF says it has collected enough information from those properties.
All properties at Ohakea will be retested. The results are due in early November.
Update 10 September 2018
Palmerston North city water supply safe
An investigation at Palmerston North Airport of soil and surface water has found the presence of PFOS in samples analysed. Palmerston North Airport Limited (PNAL) chief executive David Lanham said seven surface water samples and 23 soil/sediment samples were taken from the airport’s former fire training area, north of the main runway and around the Rescue Fire Station site.
“Test results received last week indicate that samples displayed elevated levels of PFOS,” Mr Lanham said.
Palmerston North City Council chief executive Heather Shotter said the affected waterways are not used for watertakes and that all drinking water bores on the city supply were tested for PFOS in April this year and given the all clear. “This means everyone on the Palmerston North water supply can be reassured it is not contaminated and is safe for consumption,” she said. Anyone with private bores within the near vicinity of the airport are asked to register their details on 06 352 8757.
MidCentral DHB Public Health Services advises the public that there should be no concerns about acute health issues caused by exposure to PFOS. However, a precautionary approach in regards to the long-term health effects should be taken by any potentially affected members of the public who live near the airport and are consuming water that is not on the city drinking water supply.
The Ministry for Primary Industries recommends that people avoid gathering food such as eels and watercress at:
Mr Lanham said Task Protection Services Limited is working closely with Palmerston North Airport Limited, Horizons Regional Council and other stakeholders to formulate a disposal plan for remaining stocks of fire-fighting foam containing PFOS which meets Environmental Protection Authority requirements. “These stocks will be replaced with fluorine-free firefighting foam,” he said.
Further information can be found on the Palmerston North City Council website and the Palmerston North Airport website.
Update 20 August 2018
Sampling near Whenuapai Air Base completed
New Zealand Defence Force (NZDF) consultants have completed sampling from ground and surface water around Whenuapai Air Base, as well as marine life in the harbour nearby.
Results from the testing are expected to be available in six to eight weeks.
Drinking water at the base, the adjacent school, the village centre on Brigham Creek Road and the recently developed Special Housing Area comes from the town supply and is not affected.
Preliminary advice from NZDF’s consultants is that while some people may be using ground water at properties close to the base, the water is sourced from a bore at a depth of between 200-300 metres and below a thick layer of fine sediment that is expected to exclude PFAS. The test results will clarify that.
Update 16 August 2018
No PFAS compounds detected near site of 1996 Skyhawk crash.
PFAS compounds have not been detected in groundwater samples taken from the area surrounding a 1996 Skyhawk crash site, test results show.
In June, specialists contracted by NZDF collected groundwater samples for testing from a variety of accessible groundwater bores up to 2km away from the crash site to see if there was any PFAS present. The testing was carried out to help local councils in their investigation into the presence of PFAS detected in the Bulls water supply earlier this year. This result indicates that this crash site should no longer be considered a plausible source of the low level of PFAS found in the Bulls water supply. The levels previously detected in the Bulls water supply were well below the Ministry of Health’s interim guidance levels for drinking water.
Update 10 August 2018
Statement from Environmental Protection Authority
The Environment Protection Authority (EPA) said it was not aware of any evidence that fire-fighting foams manufactured using PFOS or PFOA continue to be discharged into the environment, as recently reported by news outlets.
“We want to allay public concerns around such reports, because we have not found any evidence that this is the case,” says Dr Fiona Thomson-Carter, the EPA’s general manager of Hazardous Substances and New Organisms.
“Our initial focus was on airports around New Zealand, where such foams may have been used historically for firefighting training and responding to emergencies. However, as part of our ongoing investigation, we are talking with managers at a range of installations, including oil facilities.
“There are only a very small number of places within New Zealand where these foams can be found and we are working with them to check that their storage arrangements ensure environmental safety. Provided the foams are appropriately stored, they pose no immediate risk to people or the environment.”
“Our aim is to ensure facilities with these foams comply with the regulations, and the firms involved are being highly co-operative,” Dr Thomson-Carter says.
We are also checking that adequate measures are being taken regarding safe disposal of non-compliant foams, by ensuring they are properly exported from New Zealand for safe destruction.
Food safety advice on Oaanui stream, South Taranaki
While the Ministry for Primary Industries has received Taranaki Regional Council’s findings and is finalising its food safety advice, it has provisionally advised the Council that eels and fish from the Oaanui stream should not be consumed. For Ngapirua stream, the Ministry says consumption should be limited to no more than one meal a month for adults and children.
The Ministry says that while there is no current evidence to suggest an increase in overall health risk related to PFAS exposure, it is taking a precautionary approach.
“To our knowledge, these are the first test results to be released on the levels of PFAS in New Zealand fish species around PFAS contaminated sites,” the Ministry said in a statement today.
“International science continues to develop on PFAS contamination in fish and waterways. There is growing evidence which shows that fish species can carry higher PFAS levels.
“Eels are high in the food chain and also tend to stay confined to smaller stretches of waterways - it’s therefore not surprising that they can carry higher PFAS levels.
“Overseas investigations in Australia, the Netherlands, Sweden and Canada have shown similar ranges of PFAS levels in freshwater fish species”.
Taranaki Regional Council investigation
Taranaki Regional Council has found eels in two South Taranaki streams with elevated levels of chemicals associated with firefighting foam – the only finding of note in a wide-ranging regional investigation into any such contamination.
The Council has referred its findings to the Ministry for Primary Industries for food safety advice. The two streams, the Oaonui and the much shorter Ngapirau, are relatively inaccessible. Iwi and local residents have been notified. The potential long-term effects of these chemicals on human health are unclear and the subject of ongoing research.
The chemicals are from a category known as PFAS, which have been used as constituents of firefighting foam. They are also widely used in or on everyday items such as furniture and carpets, cooking equipment and food storage containers. New Zealand has no standards for PFAS chemicals in foodstuffs.
The Council’s Director-Environment Quality, Gary Bedford, says the Council decided to begin an investigation after environmental PFAS contamination was found in other regions earlier this year.
The firefighting foam was formulated for use on hydrocarbon fires in particular, and the Council focused on sites where it had been stored. In most cases, the companies involved were doing their own checks and investigations.
As well as the eel result, investigations have found:
He says the Council is continuing to work with the community and companies involved in environmental investigations and keeping stakeholders informed.
Update 26 July 2018
Defence testing near Whenuapai Air Base
The New Zealand Defence Force (NZDF) is contacting some landowners living near Whenuapai Air Base seeking permission to test ground and surface water on their properties for the presence of PFAS. This follows the detection of PFAS at Whenuapai Air Base.
Drinking water at the base, the adjacent school, the village centre on Brigham Creek Road and the recently developed Special Housing Area comes from the town supply and is not affected.
NZDF has been working to determine how and where the ground water flows to from Whenuapai Air Base, and to support the local community. Auckland Council has been consulted and has been assisting NZDF with its preliminary investigation with regional and locally specific information and knowledge.
Preliminary advice from NZDF’s consultants is that while some people may be using ground water at properties close to Whenuapai Air Base, the water is sourced from a bore at a depth of between 200-300 metres and below a thick layer of fine sediment that is expected to exclude PFAS. Testing will clarify that.
Tests will also be carried out on marine life in the harbour nearby to better understand the presence of PFAS in the area.
Health advice remains that there is no acute health risk from exposure to PFAS compounds. There is currently no consistent evidence that environmental exposures to PFOS and PFOA causes adverse human health effects.
Update 18 July 2018
Testing around old crash site near Bulls
The New Zealand Defence Force (NZDF) is testing an area where a Skyhawk crashed in 1996 to help inform the investigation of PFAS in the Bulls water supply.
Earlier this year, at the request of the local councils, NZDF tested the town water supplies of Sanson and Bulls for PFAS compounds. While Sanson came back clear, low levels of PFAS were detected in the Bulls water supply. The levels detected were well below the Ministry of Health’s interim guidance levels for drinking water.
NZDF agreed to help Rangitikei District Council and Horizons Regional Council understand where the PFAS might have come from. Part of that investigation involves testing in the vicinity of the site of the Skyhawk crash to the north of Bulls, to determine whether firefighting foam used at the site could plausibly be a source of the PFAS in the Bulls water supply.
Testing will be carried out by specialists contracted by NZDF on groundwater from existing wells adjacent to the site. NZDF has already tested some supply wells between the crash site and Bulls and has found no PFAS above the laboratory limit of reporting.
The results from these tests will take about eight weeks and will be provided to landowners, statutory regional authorities and the All of Government group involved in the PFAS response.
Ohakea water scheme design study
Funding has been provided to the Manawatū District Council to conduct a study into creating a water scheme for the community at Ohakea.
The Ministry for the Environment has approved funding of $50,000 for a detailed design study that will look at the options for an improved water scheme and the potential costs involved.
The government has not made any decisions regarding the contribution it may make to funding the proposed scheme.
Update 4 July 2018
Latest PFAS testing results reported to Ohakea landowners
Results of third stage testing for the PFAS compounds PFOA, PFOS and PFHxS have been reported back to landowners near RNZAF Base Ohakea. The testing is to investigate the extent of PFAS compounds in the environment around the base.
These results provide the most recent update to the broad New Zealand Defence Force testing programme that included sampling and testing in December 2017 and February-March 2018. This third round of testing was conducted in May, and included groundwater and surface water sampling.
The number of samples that detected PFAS compounds has not significantly changed from the previous rounds of testing. Of the 70 groundwater samples tested, 18 samples exceeded the interim guidance levels for drinking water for the sum total of PFOA and PFHxS, up from 15 samples in the previous testing round.
Alternative drinking water supplies have been offered to people at all affected properties.
The Ministry for the Environment (MfE) is leading the All of Government PFAS Programme. Claire Richardson, MfE’s Chief Operating Officer, said the advice of health officials remains that there is no acute health risk, but a precautionary approach is being taken because the long term effects are uncertain.
“The Ministry of Health says the findings from the third stage testing confirm their advice following the first and second rounds of sampling that there is not a significant public health risk.
“Currently there is no consistent evidence that environmental exposures at the low levels New Zealanders are generally exposed to will cause harmful health effects.”
Claire Richardson said all affected households in Ohakea had been offered alternative water supplies as a precautionary measure when testing was done.
“We are working directly with everyone affected around Ohakea, to provide them with advice and support tailored to their individual needs.”
The Ministry for Primary Industries (MPI) has reviewed the latest results and their advice also remains the same.
“MPI says there is no risk to the general food supply from produce grown on the tested properties.
“MPI will continue to monitor any published research on PFAS to ensure our advice is correct, and update residents as appropriate.”
Claire Richardson said PFAS was one of a number of emerging contaminants that is being grappled with around the world, and New Zealand is working proactively to identify potentially contaminated sites.
“Our priority is working with affected communities,” she said.
“A fourth round of testing of properties near Ohakea will take place later in the year.”

Latest PFAS testing results reported to Woodbourne landowners
Results of third stage testing for the PFAS compounds PFOA, PFOS and PFHxS have been reported back to landowners near RNZAF Base Woodbourne. This testing is to investigate the extent of PFAS compounds in the environment around the base.
These results provide the most recent update to the broad New Zealand Defence Force testing programme that included sampling and testing in December 2017 and February-March 2018. This third round of testing was conducted in May, and included groundwater and surface water sampling.
The number of samples that detected PFAS compounds has not significantly changed from the previous rounds of testing. None of the groundwater samples exceeded the interim guidance levels for drinking water. More surface water samples were taken in this round, with a similar percentage of samples having detectable levels of PFAS. Some groundwater wells could not be re-tested as they are not operational during the winter months.

Following the first round of testing in December last year, the testing zone around Base Woodbourne was expanded for the second stage of testing.
One hundred and sixty eight groundwater samples were taken in Woodbourne in the second stage of testing, up from 67 samples in the first stage. One sample was found to contain PFAS concentrations that exceed the interim guidance levels for drinking water, but the bore from which this sample was obtained is not used for drinking water purposes. Two samples that exceeded the guidance levels during the first stage of testing were found to be under the guidance levels in the second stage testing.
The Ministry for the Environment (MfE) is leading the All of Government PFAS Programme. Claire Richardson, MfE’s Chief Operating Officer, said the advice of health officials remains that there is no acute health risk, but a precautionary approach is being taken because the long term effects are uncertain.
“The Ministry of Health says the findings from the second stage testing confirm their advice following the first round of sampling that there is not a significant public health risk.
“Currently there is no consistent evidence that environmental exposures at the low levels New Zealanders are generally exposed to will cause harmful health effects.”
Claire Richardson said all affected households in Woodbourne have been offered alternative water supplies as a precautionary measure while testing is being done.
“We are working directly with everyone affected around Woodbourne, to provide them with advice and support tailored to their individual needs.”
The Ministry for Primary Industries (MPI) has reviewed the latest results and their advice also remains the same.
“MPI says there is no risk to the general food supply from produce grown on the tested properties.
“MPI will continue to work with landowners who regularly consume home grown and home raised foods to ensure any concerns are addressed.”
Claire Richardson said PFAS was one of a number of emerging contaminants that is being grappled with around the world, and New Zealand is working proactively to identify potentially contaminated sites.
“Our priority is the health of affected people,” she said.
“Monitoring of properties near Woodbourne will continue through the year.”

Latest PFAS testing results reported to Ohakea landowners
Results of second stage testing for the PFAS compounds PFOA and PFOS have been reported back to landowners near RNZAF Base Ohakea.
Following the first round of testing in December last year, the testing zone around Base Ohakea was expanded for the second stage of testing.
Seventy-four groundwater samples were taken in Ohakea in the second stage of testing, up from 26 samples in the first stage. Six wells servicing eight households returned results with levels at or above the interim drinking water guidelines. Two of these wells are newly identified and servicing three households in total.
The Ministry for the Environment (MfE) is leading the All of Government PFAS Programme. Claire Richardson, MfE’s Chief Operating Officer, said the advice of health officials remains that there is no acute health risk, but a precautionary approach is being taken because the long term effects are uncertain.

Update 29 March 2018
Results released this week showed no PFAS contamination is present in the Sanson town water supply. The Manawatu District Council took up New Zealand Defence Force’s offer to undertake the testing because of the town’s proximity to the Ohakea Base.
Members of the PFAS All of Government group project team were invited to speak to the Local Government New Zealand (LGNZ) National Council on 23 March. The meeting was a good opportunity to update mayors and chairs on government’s engagement with councils and plans to partner with them in identifying and managing PFAS contamination.
Regional Councils have been asked to identify high priority sites for potential PFAS contamination by the end of March. The responses are being sent to the Ministry for the Environment. A moderation exercise will take place, with details for each site affirmed and assessed. This material will be used to develop a prioritised list of sites that may potentially be contaminated with PFAS. The list will be used to guide where further investigations are undertaken. The All of Government Programme will work with Regional Councils and/or landowners to investigate these sites.
Update 23 March 2018
The New Zealand Defence Force is continuing its testing programme on and around Defence sites. Landowners around the Ohakea and Woodbourne bases will receive results of the latest round of testing on their properties around the end of April.
Given the proximity of Bulls and Sanson to Ohakea, Defence offered to test the water supplies of the two towns. The Rangitikei District Council has welcomed the results for Bulls, showing PFAS levels to be well below the national Drinking Water Guidelines and that the town’s water supply safe to drink.
The Manawatu District Council will release results for Sanson once they have been received.
Fire and Emergency New Zealand is developing a testing programme for its sites.
A National Investigation Workstream is being led by the Ministry for the Environment, working in partnership with regional councils to identify and investigate potential high risk sites in their regions.
Officials from the All of Government group met with the Christchurch City Council and Environment Canterbury on 7 March to discuss PFAS issues and the investigation programme, and had a similar meeting with Auckland Council staff and elected representatives on 13 March.
Earlier this month the Environmental Protection Agency (EPA) served a Compliance Order on Task Protection Services Ltd, the firm that owns and controls fire trucks and fire-fighting foams at Palmerston North, Gisborne, and Hawkes Bay airports.
At Palmerston North Airport, laboratory test results on two fire trucks and various storage drums were positive for PFAS. At Gisborne and Hawkes Bay airports, EPA investigators found drums of fire-fighting foam either explicitly labelled as containing “PFAS (PFOA or PFOS)” or labelled with the names of products known to contain PFOS.
The compliance order requires Task Protection Services Ltd to stop the use of fire-fighting foam containing PFOS when responding to emergencies by 4 May. In the interim it may continue using the foam for emergencies, in the interests of safety. The compliance order also requires Task Protection Services immediately to cease using PFOS foam for training or testing purposes.
This action follows a similar EPA Compliance Order being served on Nelson Airport on 27 February.
Update 1 March 2018
The New Zealand Defence Force has been concentrating its investigations at bases where firefighting training has occurred and where drinking water at properties surrounding the base is taken from bores and wells – Ohakea and Woodbourne.
Bases where firefighting training has been carried out but where the drinking-water is sourced remotely (eg Whenuapai, Hobsonville and Devonport) are the next priority for investigation.
Research into the historical use of the former NZDF base at Hobsonville, and the remediation of the site carried out when NZDF vacated it, has cleared it as a possible source of concern for PFAS contamination.
NZDF is now assessing Devonport Naval Base. Initial testing of soils, sediments and runoff at the Sea Safety Training Squadron has found PFAS compounds in sample sites. More testing is to be carried out to confirm those initial findings and to provide more information.
Drinking-water on the base and in the community is sourced from Auckland city town supply and is therefore not affected.
NZDF is starting limited testing of a tidal area, including of marine life, at Ngataringa Bay, to better understand the potential presence of PFAS in the area. This work will start early March.
MPI says that there is no evidence or suggestion that there is a current food safety issue. MPI food safety experts will review any findings.
Ministry of Health advice continues that there is no acute health risk.
Update 23 February 2018
NZDF, at the request of wine growers, tested grapes from vineyards in the vicinity of the base at Woodbourne for the presence of PFOS and PFOA. The results have come back clear - no PFOS or PFOA was detected. We are pleased to be able to provide this information and reassurance for growers and the wine industry. The Ministry for Primary Industries is confident that there is no food safety risk for grapes or wine from PFAS.
Update 25 January 2018
The first stage of testing for potential water contamination at properties neighbouring the Ohakea and Woodbourne airbases is complete.
Following tests on 64 properties, seven have been identified where water used for drinking tested above the interim drinking water guideline for PFAS compounds. We are currently sharing the results with those people whose properties were tested.
The advice of health officials remains that there is no acute health risk, but a precautionary approach is being taken because the long term effects are uncertain. Government agencies and local councils are working with affected families to make sure they have the information and support they need.
The Ministry for Primary Industries (MPI) advise there is no impact on the national food chain.
Next steps
The areas being tested at both locations will be slightly expanded to be absolutely sure of the extent of the problem. And further tests will be carried out over the next few months to confirm the initial findings.
The Ministry for the Environment (MfE) has led an All of Government response to assess and deal with potential PFAS contamination of land and groundwater around the country. The group is made up of representatives from Ministry of Defence, Ministry of Health, Ministry for Primary Industries, Environmental Protection Authority, Department of Prime Minister and Cabinet, as well as MfE. The All of Government response is focussed on identifying and investigating sites where PFAS may have been historically used and which have the potential for contamination, and working in partnership with local authorities and local communities to ensure they are well informed on the issue.
PFAS chemicals have been widely used in a range of consumer and industrial products. People are exposed to small amounts of some PFAS in everyday life, through food, dust, air, water and contact with products that contain these compounds.
