"Responding to the threat of per- and polyfluoroalkyl substances (PFAS) in the Tucson aquifer, the U.S. Environmental Protection Agency (EPA) has entered into an agreement with Tucson Airport Authority.

This agreement constitutes a proactive step to address contamination from the airport property, aiming to combat an ongoing threat to a primary drinking water source for the city of Tucson.

PFAS chemicals originating from the Tucson International Airport Area (TIAA) Superfund Site are threatening the water quality of the drinking water system managed by Tucson Water (the city of Tucson’s water department). The agreement being announced will help ensure the protection of the aquifer and address groundwater contamination."
