The U.S. Environmental Protection Agency (EPA) today announced new enforceable federal standards for per- and polyfluoroalkyl substances (PFAS) in drinking water. This includes a new enforceable Maximum Contaminant Level (MCL) of 4.0 parts per trillion (ppt) individually for PFOA and PFOS and 10 ppt individually for PFNA, PFHxS and GenX. Additionally, the EPA finalized an MCL at a hazard index of 1 when a combination of PFNA, PFHxS, GenX and PFBS are present in a mixture.
