IV. EPA'S NEW REGULATIONS ON PFAS

Topic Current Rule Revised Rule Applicable Year
PFAS MCLs There are no PFAS MCLs currently enforced by the EPA.

The following states have MCLs on one or multiple PFAS substances: California, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Pennsylvania

Vermont, Wisconsin
In 2024, the EPA established legally enforceable MCLs for six PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, and HFPO-DA (with individual MCLs), and a Hazard Index MCL for mixtures of two or more of PFHxS, PFNA, HFPO-DA, and PFBS.

Public water systems must monitor for these PFAS and complete initial monitoring by 2027. Public water systems that violate one or more of these MCLs must take action to reduce levels and provide public notification beginning in 2029 (five years after the rule establishment).
