EPA announced that on April 19, 2022 they will provide an update to the National Drinking Water Advisory Council
“….on a proposed National Primary Drinking Water Regulation (NPDWR) for per- and polyfluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS).”
Background On Development of PFAS MCLs:
In March 2021, EPA published a decision to regulate PFOA and PFOS in drinking water (that were listed under the Contaminant Candidate List). Under the Safe Drinking Water Act (SDWA), once EPA made the decision to regulate PFOA and PFOS in drinking water, the Agency had 24 months to propose regulations (i.e., by March 2023) and 18 months after that to publish final regulations (i.e., by September 2024). In October 2021, EPA published a PFAS Strategic Roadmap addressing PFAS contamination in different media. According to the PFAS Strategic Roadmap, EPA intends to move faster on setting the drinking water standards than allowed under the SDWA and plans to propose MCLs during fall of 2022 and publish final MCLs by the fall of 2023.
