EPA Announces Proposed Decision to Regulate PFOA and PFOS in Drinking Water

The U.S. Environmental Protection Agency (EPA) has proposed regulatory determinations for perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in drinking water. The preliminary determinations mark a key milestone in EPA’s extensive efforts under the PFAS Action Plan to help communities address per- and polyfluoroalkyl substances (PFAS) nationwide.

“The U.S. leads the world in providing access to safe drinking water for its citizens, thanks in part to EPA’s implementation of the Safe Drinking Water Act,” said EPA Administrator Andrew Wheeler. “Under President Trump’s leadership, EPA is following through on its commitment in the Action Plan to evaluate PFOA and PFOS under this Act.”

Aggressively addressing per- and polyfluoroalkyl (PFAS) is an ongoing and high priority effort for EPA. EPA’s PFAS Action Plan commits the agency to take important steps that will enhance how the agency researches, monitors, detects, and addresses PFAS. Over the past year, EPA has made significant progress under the Action Plan to help states and local communities address PFAS.

Through the recent action, EPA is seeking public comment on its proposed regulatory determinations for eight contaminants listed on the fourth Contaminant Candidate List. The Agency is proposing to regulate two contaminants, PFOS and PFOA. EPA is also asking for information and data on other PFAS substances, as well as seeking comment on potential monitoring requirements and regulatory approaches EPA is considering for PFAS chemicals. The Agency is proposing to not regulate six contaminants: 1,1-dichloroethane, acetochlor, methyl bromide, metolachlor, nitrobenzene, and RDX.

EPA will seek comment on these preliminary determinations for 60 days after the notice is published in the Federal Register.
