What’s in it

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.
