Fluoridation of public water supplies provisions modification

This bill (SF 2699) amends Minnesota Statutes section 144.145 to clarify that municipalities operating public water systems cannot be required to add fluoride if the water naturally contains fluoride within the levels set by the state commissioner of health. It directly affects public water suppliers, which retain the choice to fluoridate but must stop adding fluoride when natural levels meet health standards. The bill specifies that the commissioner must establish rules for fluoride content, testing methods, and record-keeping for systems that choose to fluoridate, while explicitly prohibiting mandatory fluoridation. The key change prevents unnecessary fluoridation when natural fluoride levels are already sufficient.
