The agency is developing a new broad PFAS testing method, a PFAS development for the NPDES program, and ambient water quality criteria to protect aquatic life from PFA.
The U.S. Environmental Protection Agency (EPA) has announced three actions to protect communities and the environment from per- and polyfluoroalkyl substances (PFAS) in waters.
"EPA is using all available tools to address PFAS contamination as part of a broader, whole-of-government effort to protect communities across the country from these chemicals," said EPA Administrator Michael S. Regan. "Today's actions help protect the health of all Americans as we deliver on our commitment to research, restrict, and remediate PFAS."

A New Testing Method
EPA is publishing a new method that can broadly screen for the presence of PFAS in water at the part per billion level. EPA's new Draft Method 1621, the Screening Method for the Determination of Adsorbable Organic Fluorine (AOF) in Aqueous Matrices by Combustion Ion Chromatography (CIC), provides an aggregate measurement of chemical substances that contain carbon-fluorine bonds. PFAS are a common source of organofluorines in wastewater.
The National Pollutant Discharge Elimination System (NPDES) program interfaces with many pathways by which PFAS travel and are released into the environment and ultimately impact people and water quality. EPA is seeking to proactively use existing NPDES authorities to reduce discharges of PFAS at the source and obtain more comprehensive information through monitoring on sources of PFAS.
EPA is also developing national recommended ambient water quality criteria for PFAS to protect aquatic life. The agency is proposing the first Clean Water Act aquatic life criteria for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS)—two of the most well-studied chemicals in this group. The criteria are intended to protect aquatic life in the United States from short-term and long-term toxic effects of PFOA and PFOS.
