Melb Airport admits PFAS contamination

Dozens of landholders are being contacted following the spread of PFAS chemicals from Melbourne Airport.

While the airport says the risk to human health is low, downstream landholders are being contacted following confirmation the chemicals have spread outside airport boundaries.

"We've conducted a number of detailed risk assessments that indicate any likelihood of human health impact by PFAS contamination for landholders downstream from the airport is low, on the basis that local water courses are not connected to Melbourne's drinking water catchment," an airport spokesman said in a statement on Thursday.
