It is possible that these regulations could be amended or delayed. However, if the Village was to anticipate a change, and that change doesn’t occur, the Village would not be able to meet the compliance deadlines currently in place.
On April 10, 2024, USEPA announced the final National Primary Drinking Water Regulation, including standards for PFOA and PFOS. At that time, USEPA established legally enforceable levels for these PFAS in drinking water and gave public water systems until 2029 to comply with Maximum Contaminant Levels (MCLs). On May 14, 2025, the USEPA announced the agency will keep the current National Primary Drinking Water Regulations (NPDWR) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), which set nationwide limits for these “forever chemicals” in drinking water but intends to extend the public water systems compliance date to 2031. According to a USEPA Press Release, “EPA plans to issue a proposed rule this fall and finalize this rule in the Spring of 2026.”
