Addressing per- and polyfluoroalkyl substances (PFAS) in the environment continues to be an active and ongoing priority for the EPA. The agency is announcing two important steps to address PFAS. First, EPA issued a memorandum detailing an interim National Pollutant Discharge Elimination System (NPDES) permitting strategy for addressing PFAS in EPA-issued wastewater permits. Second, EPA released information on progress in developing new analytical methods to test for PFAS compounds in wastewater and other environmental media. Together, these actions help ensure that federally enforceable wastewater monitoring for PFAS can begin as soon as validated analytical methods are finalized.
