PFAS Investigation &

Holsworthy Barracks

Holsworthy Barracks PFAS Investigation


Summary of the Investigation

Defence commenced a detailed environmental investigation to better understand the nature and extent of PFAS, on and around Holsworthy Barracks, in June 2017.

The objective of this environmental investigation is to identify the nature and extent of PFAS in the environment from the use of legacy firefighting foam at the Base.

There are three main stages to the investigation:

Preliminary Site Investigation
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 second stage of the investigation, the Detailed Site Investigation (DSI), has commenced. Once the DSI is complete, a detailed report including the sampling results will be prepared and provided to relevant government agencies, regulatory bodies and the local community.

Human Health and Ecological Risk Assessment
The DSI findings will be used to inform the requirement to conduct a Human Health and Ecological Risk Assessments (HHERA). If required, the HHERA will evaluate potential exposure pathways to people, plants and animals and will be used to inform potential actions to reduce PFAS exposure.
Further information on the investigation process can be found at the investigation process page.

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.
