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.

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

The U.S. Environmental Protection Agency, on March 14, 2022, issued both a final rule incorporating revised ASTM International standard practices, ASTM International’s E1527–21 ‘‘Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,’’ and a proposed rule soliciting comment on this action.

After a lengthy committee process, ASTM International revised its standard practice for Phase I environmental site assessments (ASTM E1527) for the first time since 2013.
