Defence is undertaking a long-term environmental investigation and assessment at the Army Aviation Centre Oakey (AACO) site and surrounding area. The investigation is part of Defence’s review of a number of its sites around Australia that used legacy fire-fighting foams containing per- and poly-fluoroalkyl substances (PFAS) including perfluorooctane (per-floo-row-ok-tane) sulfonate (sul-fon-ate), known as PFOS, and perflourooctanoic (per-floo-row-ok-tan-oh-eek) acid, known as PFOA, as active ingredients.

When Defence commenced its investigations into PFAS, PFOS and PFOA were the primary contaminants of concern. More recently enHealth has advised perfluorohexane sulfonate (PFHxS) should also be considered and has developed a screening criteria for drinking water and recreational water. All Defence environmental investigations into PFAS now consider PFOS, PFOA and PFHxS.


PFAS are emerging as a concern around the world because they are persistent in the environment.
