Singleton Military Area PFAS Investigation


Summary of the Investigation

Singleton Military Area
In July 2018, Defence commenced a detailed environmental investigation into per- and poly-fluoroalkyl substances (PFAS) at, and in proximity to, Singleton Military Area.

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 Preliminary Site Investigation is now complete and the report is available on the publications page. This stage involved:
  • Obtaining, reviewing and consolidating existing reports and information,
  • Interviews with Defence personnel,
  • Site inspections, and
  • Limited soil, groundwater, surface water and sediment sampling.
Detailed Site Investigation
Defence commenced the Detailed Site Investigation in early 2019. This stage will involve sampling of water, soil, sediment plants and animals 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 and Ecological Risk Assessment (if required)
The Detailed Site Investigation findings will be used to inform the requirement to conduct a Human Health and Ecological Risk Assessment. If required, the assessment 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.
