Investigations have detected PFAS in some areas at the Airport. The detection of PFAS is not unexpected given the past use of PFAS-containing fire-fighting foams at the site. PFAS has also been used in many domestic and industrial products and background levels may be present from these other sources.

Residents of Quirindi do not need to take any additional precautions to limit their exposure to PFAS and investigations have now concluded.

PFAS is confined to the training pad area and does not appear to be migrating. As a precaution, BAE Systems, one of the users of the Airport, will voluntarily conduct six-monthly monitoring for the next two years.
