The U.S. Environmental Protection Agency announced a Final Rule on April 19, 2024, designating two of the most common per- and polyfluoroalkyl substances—PFOA and PFOS, including their salts and structural isomers—as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act.

The final rule on the National Primary Drinking Water Regulation for per- and polyfluoroalkyl substances was announced by the U.S. Environmental Protection Agency on April 10, 2024. This update summarizes the rule and analyzes its implications for regulated entities.

U.S. Environmental Protection Agency Administrator Michael Regan signed two proposed rules related to per- and polyfluoroalkyl substances and the agency’s corrective action authority under the Resource Conservation and Recovery Act on January 31, 2024. These proposed rulemakings align with EPA’s Strategic Roadmap, announced in 2021 as a “whole-of-agency” approach to addressing PFAS.

For the first time and after much anticipation, the Environmental Protection Agency proposed National Primary Drinking Water Regulations for key "forever chemicals."

On November 3, 2021, the Washington Department of Ecology published its final PFAS Chemical Action Plan, which provides a roadmap for addressing uses and releases of those chemicals in Washington State to protect human health and the environment.
