USEPA Announces Final National Primary Drinking Water Regulation for PFAS Compounds
On April 10, 2024, the United States Environmental Protection Agency (USEPA) announced the final National Primary Drinking Water Regulation (NPDWR) to establish legally-enforceable Maximum Contaminant Levels (MCLs) for certain per- and polyfluoroalkyl substances (PFAS) in drinking water. The individual compounds covered by the proposed regulation are: perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA, sometimes referred to as “GenX” compounds), and perfluorohexane sulfonic acid (PFHxS). Additionally, the final rule covers PFAS mixtures containing at least two or more of PFHxS, PFNA, HFPO-DA, and perfluorobutane sulfonic acid (PFBS) using a Hazard Index MCL to account for the combined and co-occurring levels of these PFAS in drinking water.
