The Arizona Department of Environmental Quality (ADEQ) is monitoring scientific, regulatory, and legal developments related to PFAS (per‐ and polyfluoroalkyl substances).
According to ADEQ, PFAS are a group of man‐made chemicals with fire‐retardant properties that have been manufactured and used by a variety of industries since the 1940s. PFAS have been used commercially in the United States to make products like certain textiles, food packaging, firefighting foam, as well as in other industrial processes and may be found in a variety of products. The U.S. Environmental Protection Agency (EPA) currently has non‐enforceable and non‐regulatory health advisory levels applicable to PFAS and very recently issued a proposed maximum contaminant level. If you recently received a notice that PFAS was detected in your water please visit the following links to obtain more information.
