The Environmental Protection Agency has announced a National Primary Drinking Water Regulation (NPDWR) to prevent per- and polyfluoroalkyl substances exposure. The agency has identified legally enforceable Maximum Contaminant Levels (MCLs) for six PFAS contaminants.
The MCLs apply to PFOA, PFOS, PFHxS, PFNA, HFPO-DA and mixtures containing two or more of PFHxS, PFNA, HFPO-DA and PFBS. These regulations mark the newest MCLs for drinking water in over 20 years.
Public water systems have until 2029 to administer solutions to decrease PFAS that exceeds the MCLs. Systems that violate one or more of these levels will be required to take action to lower PFAS levels and notify the public.
