Preliminary Site InvestigationFurther information on the investigation process can be found at the investigation process page.
The first stage of the investigation, the Preliminary Site Investigation (PSI), has been completed with outcomes provided to the local community in August 2017.
Detailed Site Investigation
The Detailed Site Investigation (DSI) is now complete and the report is available on the publications page. The DSI involved sampling on-base and in the surrounding region.
Human Health and Ecological Risk Assessment
Defence is now conducting a Human Health and Ecological Risk Assessment (HHERA) to evaluate potential exposure pathways to people, plants and animals. The HHERA will be used to inform actions to reduce PFAS exposure, if required.
The findings from the investigations will be used to identify and prioritise site specific management actions to address PFAS contamination.
Defence is committed to regularly updating the community throughout the investigation. As well as community engagement events, updates are provided through the project website, newsletters and factsheets as new information becomes available.
