Per- and polyfluoroalkyl substances, also called PFAS, are a family of man-made chemicals widely used in many consumer products since the 1940s.
In recent years, Tucson has taken steps to prevent PFAS from entering the potable water system by shutting off groundwater wells and redirecting water discharges from the Tucson Airport Remediation Project (TARP).
Both Pima County and the City of Tucson continue to monitor for the presence of PFAS substances and are committed to the protection of public health.
Additional information about PFAS and their risks can be found below.
