Health hazards caused by perfluorooctanoic acid, PFOA, and perfluoro octane sulfonic acid, PFOS, and four other potentially deadly substances became the topics of a National Primary Drinking Water Regulation, NPDWR, proposed by the Environmental Protection Agency, EPA, according to a report released on March 14, 2023.

The proposed Drinking Water Regulation does not require any action until it is finalized, which is expected to occur sometime prior to the new year in 2024.

“If fully implemented, the rule will prevent thousands of deaths and reduce tens of thousands of serious PFAS-attributable illnesses,” the EPA states. Common PFAS can be found in grease-resistant paper; microwave popcorn bags; plastic water bottles; nonstick cookware; stain -resistant coatings for carpets; cleaning products, cosmetics; paint; and many other products. PFAS has been dubbed the “forever chemicals” because they can linger in the environment for decades or longer.

EPA seeks public comment on the proposed regulation by May 30, 2023. To learn more or submit a comment Click Here.

The regulation, if approved, establishes legally enforceable levels, referred to as Maximum Contaminant Levels, MCLs, for the six PFAS in drinking water.

EPA’s proposal limits PFOA and PFOS to 4 parts per trillion, ppt, in drinking quality water. The proposal also includes limits on the other four PFAS, based on their estimated hazard level.
