PFAS in Tucson: EPA orders cleanup by US Air Force, Air National Guard
The U.S. Environmental Protection Agency is demanding the U.S. Air Force and Arizona National Guard take action as concentrations of toxic “forever chemicals” are increasing in the groundwater in a historically contaminated area on Tucson’s south side. The EPA found the pollution came from the nearby military properties and ordered them to clean up the contamination. High concentrations of PFAS, or per- and polyfluoroalkyl substances, were detected in Tucson’s groundwater near the Tucson International Airport at the National Guard base and at a property owned by the U.S. Air Force. The contaminants threaten the groundwater extracted at a water treatment run by Tucson Water in the Tucson Airport Remediation Project area, known as TARP. That water was intended for drinking, the EPA said in its May 29 order.
