The EPA revealed its draft surface water quality standards for PFAS, which would allow states to consider forever chemicals when permitting wastewater discharges. The draft announced Thursday focuses on the Environmental Protection Agency’s proposed recommended ambient water quality criteria for three types of per- and polyfluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorobutane sulfonic acid (PFBS). The draft criteria, which would not be legally binding when finalized, are open for public comment for 60 days.
