What’s in it

AI summary New rules would stop people from adding fluoride to public and private drinking water systems. County health boards and the environmental protection commission would set standards to ensure fluoride levels in the water stay at natural background levels.1

Read the official explanation

The inclusion of this explanation does not constitute agreement with the explanation’s substance by the members of the general assembly. This bill prohibits the addition of hydrofluorosilicic acid or any other fluoride-based additive into public and private drinking water supply systems. The bill requires county boards of health to adopt standards for private drinking water supply systems that do not allow for an amount of hydrofluorosilicic acid or any other fluoride-based compound that is higher than ambient background levels. The bill also requires the environmental protection commission to adopt standards for public drinking water supply systems that do not allow for an amount of hydrofluorosilicic acid or any other fluoride-based compound that is higher than ambient background levels.

Why it matters. Public and private drinking water supply systems would be prohibited from adding hydrofluorosilicic acid or other fluoride-based additives. County boards of health and the environmental protection commission would be required to adopt new standards to ensure fluoride levels in these water systems do not exceed ambient background levels.2
