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), has been completed.

Detailed Site Investigation
The second stage of the investigation, the Detailed Site Investigation (DSI) has commenced 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
If required, a Human Health and Ecological Risk Assessment (HHERA) may be conducted to evaluate potential exposure pathways to people, plants and animals and to inform potential actions to reduce PFAS exposure. The decision to conduct a HHERA is informed by the findings of the DSI.
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.
