RAAF Base Townsville PFAS Investigation
Summary of the Investigation
The objective of this environmental investigation is to identify the nature and extent of PFAS in the environment from the use of legacy fire-fighting foam at the Base.
There are three main stages to the investigation:
Preliminary Site InvestigationFurther information on the investigation process can be found at the investigation process page.
The first stage of the investigation, the Preliminary Site Investigation (PSI), has been completed.
Detailed Site Investigation
The Detailed Site Investigation (DSI) has been completed. This stage involved sampling of soil, sediment, surface water and groundwater. A detailed report has been finalised and is available on the publications page.
The Detailed Site Investigation findings recommended that additional environmental sampling in the Investigation Area be conducted and reported in an addendum to the Detailed Site Investigation Report. Additional investigations include wet season groundwater, surface water and sediment monitoring. This report is expected to be complete and findings released in the third quarter of 2018 and will be made available to the public.
Human Health Risk Assessment and Ecological Risk Assessment
Based on the initial findings conducted for the DSI, a Human Health Risk Assessment (HHRA) and an Ecological Risk Assessment (ERA) have commenced. These Assessments will evaluate potential PFAS exposure risks to the human population and ecology, and inform actions to mitigate risks. The HHRA and ERA are expected to be complete and findings released by the third quarter of 2018 and will be made available to the public.
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.
