PFAS Investigation & Management

Army Aviation Centre Oakey
In October 2018, Defence completed the detailed environmental investigation into per- and poly-fluoroalkyl substances (PFAS) on, and in the vicinity of, Army Aviation Centre Oakey.

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.

Defence is now focusing on management and remediation of PFAS contamination within the Management Area. Further information is available on the management activities 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.

Human Health Risk Assessment

Complete
December 2017

This stage built on previous Human Health Risk Assessments by using newly adopted Health Based Guidance Values from the Department of Health and considering new sampling and survey data.

Environmental Site Assessment

Complete
December 2017

This stage refined the 2016 Environmental Site Assessment by addressing data gaps and uncertainties regarding the extent of contamination in some areas. The assessment outlined the location of PFAS in the Investigation Area and how it is moving.

2016 Environmental Site Asssessment

Complete
Jul 2016

Similar to a Detailed Site Investigation, the 2016 Environmental Site Asssessment involved sampling of soil, sediment, surface water and groundwater, to better understand how PFAS moves through the environment.
