Fluoride addition to public drinking water prohibition

SF 3424 prohibits adding fluoride to public drinking water systems in Minnesota. It requires all public water systems (serving at least 15 households or 25 people for 60 days annually) to stop adding fluoride by August 1, 2025. The bill repeals Minnesota Statutes 2024, section 144.145, which previously permitted fluoridation, and authorizes the state health commissioner to enforce the prohibition with daily fines for noncompliance. This change directly affects municipal and privately owned water providers across the state.
