Toxic foam used at Sunshine Coast Airport
A FIRE-fighting foam containing traces of the toxic chemicals blamed for contaminating the groundwater at Oakey was used at the Sunshine Coast Airport.
An Airservices Australia spokesman said a foam called Ansulite was used at the Sunshine Coast Airport from 2004 to 2010.
The spokesman said Air Services had switched to Ansulite because of safety concerns over another fire-fighting foam, 3M Lightwater, which contained perfluorooctane sulfonate (PFOS) and other perfluorinated compounds (PFCs) such as perfluorooactanoic acid (PFOA).
But the spokesman said Ansulite was later found to contain traces of PFOS and PFOA and was replaced with a PFC-free foam in 2010.
The spokesman said the 3M Lightwater foam was never used at the Sunshine Coast Airport but confirmed some testing had been done because of the traces of PFCs in the Ansulite foam.
"While the Ansulite product at Sunshine Coast only contained trace elements of PFCs, Airservices is currently undertaking precautionary site investigations at the airport to enhance our understanding of potential PFC levels,” the spokesman said.
