A bill for an act relating to the use of fluoride-based additives in private and public water supply systems.

HF 2395 bans the addition of hydrofluorosilicic acid and other fluoride-based additives to both public and private drinking water systems in Iowa. It requires county health boards to set private water standards that prevent fluoride levels exceeding natural background amounts, and directs the environmental protection commission to establish public water standards with the same limit. The bill updates drinking water rules to ensure they align with federal standards while prohibiting artificial fluoride addition. This directly affects all public water utilities and private well owners subject to county health regulations. The policy change specifically eliminates the use of fluoride additives in water treatment, setting maximum allowable levels at naturally occurring background concentrations.
