Albion Park Site - Environmental investigation
FRNSW has engaged GHD Pty Ltd (GHD) to undertake an environmental investigation into the presence of PFAS on, and in the vicinity of, FRNSW’s Albion Park training site.
The investigation is part of a review of a number of our sites across NSW where legacy firefighting foams containing PFAS have been stored, used and disposed of.
PFAS is a class of manufactured chemicals generally present in aqueous film forming foam (AFFF) which was used extensively worldwide from the 1970s due to its effectiveness in fighting liquid fuel fires.
The term PFAS relates to a large number of compounds. The primary PFAS compounds of interest to the investigation include perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorooctanoic acid (PFOA).
FRNSW’s preliminary sampling focused on these compounds as guideline values exist and they have been deemed important to assessing risk.
The firefighting foams now used by FRNSW are more environmentally sensitive and do not contain PFOS or PFOA.
The preliminary investigation commenced in June 2016 and was completed in February 2017. Some of the objectives of this initial investigation included:
- reviewing site history for AFFF use and identifying potential sources of PFAS
- investigating and modelling how PFAS moves through the environment
- sampling and laboratory analysis of groundwater, surface water, soils and sediments.
FRNSW now have results back which confirm PFAS is present in environmental samples collected. In some cases, levels are above the Food Standards Australia and New Zealand (FSANZ) health based guidance values.

Phase 2 Environmental Site Assessment (ESA)
A more detailed assessment of the Albion Park site and surrounding area commenced in June 2017 with additional off-site sampling to further understand the pathways for potential migration of PFAS from the site.
The community was asked to assist these investigations by completing a water survey to help us identify how potentially contaminated water is being used. The water use survey was distributed to 176 people and a fact sheet was also distributed to 1700 people within a 1.4 km radius.
Analysis of the soil and sediment samples on-site indicated that the concentrations of PFAS were below the nominated human health and ecological screening criteria.
Leachability testing confirmed that PFAS impacted soils and sediments have the potential to release PFAS to the environment at concentrations exceeding the nominated screening levels.
All off-site sediment samples reported detections of PFAS with the exception of 2 locations. This indicates that PFAS is likely to be migrating off-site via the surface water drainage pathways.
Some of the ground and surface water samples offsite exceeded drinking and recreational criteria. The water use survey indicated that respondents mainly used town and rain water. Additional investigation is required to assess whether impacted groundwater is migrating onto the site from the airfield located to the west and south of the site. Levels of PFAS in surface water decrease with increasing distance from site.
Concentrations of PFAS in a surface water sample near the discharge point of Albion Creek to Lake Illawarra exceeded ecological guidelines in December 2016. However, was below the LOR in May 2017. Surface water samples collected in Koona Bay, Lake Illawarra were below the nominated ecological guidelines.
FRNSW will continue to work closely with the EPA, other agencies and the community to develop strategies to minimise further migration of PFAS and to continually assess the risk to human populations and ecosystems.

Consulting with stakeholders
FRNSW is committed to being open and transparent about these investigations. We will update the community at key stages throughout the investigations, and we encourage the community to contact us about their concerns.
Phone contact through the 1800 number, direct mail, and fact sheets will provide further support to assist with information access as the investigation progresses.
Contact details can be found here.
