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:
Community consultation events are recorded here. Upcoming events appear first.
On 5 April 2017 Defence held a community walk-in session to discuss the investigation into per- and poly- fluoroalkyl substances (PFAS) at Army Aviation Center Oakey. The event included a presentation on the Sensitivity Assessment Report Results. To read more about this event, please download the presentation.
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.
In November 2016, Defence conducted a community information session focusing on the preliminary ecological risk assessment at Oakey, which forms part of the Stage 2C environmental investigation of the area. It provided information on the potential impacts of PFAS on the ecosystem and outlined the risk levels associated with different potential outcomes of this.
In September 2016, Defence conducted a community information session focusing on the human health risk assessment that forms part of the Stage 2C environmental investigation at Oakey. It outlined the extent of groundwater contamination in Oakey and examined the potential danger levels and risks of human exposure to PFAS.
In July 2016, Defence conducted a community information session focusing on the environmental site assessments underway, which form part of the Stage 2C environmental investigation. It detailed previous environmental investigations and their results, and what this meant for ongoing investigations into groundwater contamination. It also included images of current sampling and monitoring programs.
