New York legislature passes stricter PFAS drinking-water limits while federal rollback is proposed
Both houses passed a bill setting New York limits of 4 parts per trillion for PFOA and PFOS and 10 for three other PFAS, with water systems to comply by May 1, 2029. As of October 7, 2026 the Senate page shows it awaiting the Governor. Federal proposals of May 20, 2026 would drop limits for those three PFAS.
The New York Legislature has passed Senate Bill S3207-B and its Assembly counterpart A8634-B (2025-2026 Regular Session), which would direct the Commissioner of Health to set drinking-water maximum contaminant levels of no higher than 4 parts per trillion for PFOS and PFOA and no higher than 10 parts per trillion for PFNA, PFHxS and HFPO-DA (GenX), with public water systems required to comply by May 1, 2029. The Senate's bill page records Senate passage on May 28, 2026 by a vote of 60 to 0, and the Assembly page records Assembly passage and return to the Senate on June 3, 2026. The bill is not law. The Senate's bill page, read on October 7, 2026, lists the bill as passed by both houses and awaiting the Governor, and a news report dated August 6, 2026 quoted a Governor's spokesperson as saying she "will review this legislation." A June 10, 2026 report states that the Governor has until year's end to decide.
