Industry & Public Water System Screening | PFAS Resources

In Arizona, there are no known manufacturers of PFAS chemicals. Research also indicates PFAS compounds were not used on large-scale industrial applications and tend to be localized near areas of potential frequent use.

In 2018, ADEQ developed and conducted a PFAS screening program for public water systems with wells near areas of potential frequent PFAS use, which included industrial and manufacturing facilities, firefighting training facilities, airports and military sites. Screening program results showed more than 94 percent of the public water systems were either non-detect for PFAS tested or below EPA’s HAL | View Report >

Public water systems with PFAS test results higher than EPA’s HAL are voluntarily working with ADEQ to reduce exposure to customers and ADEQ is conducting expanded sampling and testing of these systems and initial screening for an additional 27 systems.
