PFAS Investigation &
Management Program

Army Aviation Centre Oakey

Oakey Investigation Summary

Defence commenced an investigation into the nature and extent of PFAS on and around Army Aviation Centre Oakey in 2012.

In 2016, Defence completed an Environmental Site Assessment (ESA), a Human Health Risk Assessment (HHRA) and a Preliminary Ecological Risk Assessment (ERA) for Army Aviation Centre Oakey. Following the completion of these assessments, it was identified that data gaps remained in some portions of the Investigation Area. As a result further works are underway to update and refine the 2016 assessment reports.

The PFAS environmental investigations are conducted in accordance with the National Environmental Protection (Assessment of Site Contamination) Measure 1999 (NEPM). Visit the Investigation Process page to view a summary of this process.

Currently, Defence is conducting additional works as part of the detailed environmental investigation that will continue through to late 2017 and include the following activities:

  • The uptake of PFAS in fruit and vegetables
  • The uptake of PFAS in chicken eggs
  • Fish and yabby sampling and analysis
  • Additional surface water and groundwater data collection, and
  • Additional sediment data collection and analysis.
In 2017, Defence released an Offsite-Human Health Risk Assessment – Sensitivity Assessment as an addendum to the 2016 HHRA report that provides additional guidance about precautionary recommendations for Oakey residents to minimise exposure to PFAS chemicals.

The most recent community information session was conducted on 5 April 2017.

Defence is working continuously towards the effective monitoring and management of PFAS contamination on, and in the vicinity of, Army Aviation Centre Oakey. Defence continues to engage with industry experts both nationally and internationally to identify the best management options for PFAS throughout Australia. More information on the current activities being undertaken by Defence can be found at the Management Activities page.

Community Survey 2017

Following the completion of the Human Health Risk Assessment, it was identified that data gaps remained in some portions of the Investigation Area. As a result of these outcomes, AECOM Australia Pty Ltd (AECOM) on behalf of Defence will conduct further works to update and refine the 2016 HHRA prepared for the AACO.

To support this work a community survey was opened in early 2017. This survey is now closed.
