EPA Proposes PFAS Safe Drinking Water Act Regulations

The U.S. EPA announced a proposal for regulating PFAS chemicals in the nation’s drinking water.  Through the U.S. EPA’s proposal, perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) will become regulated through the Safe Drinking Water Act (SDWA). According to the U.S. EPA, this preliminary determination is a necessary step toward providing state and local communities with key information about PFOA and PFOS in drinking water.
