Since September 2017, a water treatment plant has been operating at Army Aviation Centre Oakey (AACO) in the Former Fire Station. The plant is treating contaminated groundwater on the Base and reinjecting the treated water back into the aquifer to remove PFAS from the environment.
The Water Sampling Summaries track the PFAS concentrations against the limits defined by the relevant adopted drinking water screening criteria. They include results for perfluorooctanoic acid (PFOA), 6:2 fluorotelomer sulfonic acid (6:2 FTS) and the sum of perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS).
The water quality data is drawn from water samples on both untreated and treated water. The summaries of water sampling results can be downloaded below.
