Gingin Satellite Airfield PFAS Investigation

Summary of the Investigation

In October 2017, Defence commenced a detailed environmental investigation into the presence of per- and poly-fluoroalkyl substances (PFAS) on and in the vicinity of Gingin Satellite Airfield.

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 Site.

The three stages to the investigation are outlined below:

Preliminary Site Investigation
The first stage of the investigation, the Preliminary Site Investigation (PSI), is currently in progress. The PSI will involve a historical review of legacy firefighting foam use and storage to identify where and when the old formulation of firefighting foam was used, how PFAS moves in the environment and people, animals and the environment that may be exposed to PFAS.

Detailed Site Investigation
The Detailed Site Investigation (DSI) will commence in early 2018 and will involve sampling on-site and in the surrounding region. A detailed report will be prepared and shared with relevant government and regulatory bodies as well as the 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 PFAS exposure risks to the human population and ecology.
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 information sessions, updates are provided through the project website, direct mail and information sheets as new information becomes available.
