RAAF Williams (Laverton) PFAS Investigation
Summary of the Investigation
Note: This investigation relates to RAAF Williams (Laverton). It does not extend to RAAF Base Point Cook.
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 InvestigationThe findings from the investigations will be used to identify and prioritise site specific management actions to address PFAS contamination.
A Preliminary Site Investigation has been completed and involved the historical review of legacy firefighting use and storage to identify where and when the foam was used (sources), how PFAS moves in the environment (migration pathways) and people, animals and the environment that may be exposed to PFAS (receptors). The Preliminary Site Investigation Report is available on the publications page.
Detailed Site Investigation
The Detailed Site Investigation has commenced and will involve sampling on-base 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 Risk Assessment and/or Ecological Risk Assessment
The Detailed Site Investigation findings will be used to inform the requirement to conduct a Human Health Risk Assessment and/or Ecological Risk Assessment. If required, the assessments 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.
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.
