The EPA under a future Biden administration is expected to quickly move to set regulations on “forever chemicals” in water and other areas, but not to restrict the entire group of thousands of the substances, attorneys said in recent interviews.

The Environmental Protection Agency is already expected to set national drinking water limits for two of these chemicals, perfluorooctane sulfonate, or PFOS, and perfluorooctanoic acid, or PFOA, said Cynthia AM Stroman, a partner in King & Spalding LLP’s Washington, D.C. office.
