PFAS Investigation & Management
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.
All findings from the investigation are available on the publications page, including detailed reports and factsheets.
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.
More information about the investigation stages is available on the investigation process page.
PFAS Management Area Plan
The PFAS Management Area Plan informs the activities Defence will undertake to manage, monitor and reduce potential risks of PFAS exposure on, and around, the Base.
Ecological Risk Assessment
The purpose of the Ecological Risk Assessment is to evaluate potential exposure-risks to plants and animals, within the Investigation Area.
Human Health Risk Assessment
The purpose of the Human Health Risk Assessment was to evaluate potential exposure-risks to people, within the Investigation Area.
Seasonal Monitoring Event
In early 2019 Townsville experienced a major rain event, resulting in widespread flooding that impacted the Investigation Area. Seasonal sampling was carried out to determine the effects of the flood event and provide information about PFAS concentrations during different seasons.
Detailed Site Investigation
The Detailed Site Investigation involved sampling of soil, sediment, surface water and groundwater to better understand how PFAS moves through the environment.
Seafood Consupmtion Human Health Risk Assessment
The Seafood Consupmtion Human Health Risk Assessment assessed potential PFAS exposure-risks to people from consuming seafood caught through recreational fishing and shellfish harvesting in the Ross River, Northview Lake and Fairfield Lake.
Preliminary Site Investigation
The Preliminary Site Investigation involved a review of the historical use of firefighting foams on-Base to identify potenital sources of PFAS contamination.
