Fluoridation of municipal water supplies provisions modified.

This bill modifies Minnesota's law on fluoridating public water supplies. It clarifies that municipalities may choose whether to fluoridate their water, but cannot add fluoride to water that naturally contains sufficient fluoride within state health guidelines. The state health commissioner must establish rules for fluoride content levels, testing methods, and record-keeping for systems that choose to fluoridate. The bill explicitly prohibits the commissioner from requiring fluoridation for any public water system. It affects all Minnesota municipalities operating public water systems and the state health department.
