This bill prohibits the addition of fluoridation chemicals to public water systems by repealing and reenacting RSA 485:14 to state that "No fluoride or any chemical containing fluoride shall be introduced into a public water system." Additionally, it repeals several related statutes, including RSA 31:17-a, RSA 44:16, RSA 52:23, RSA 485:14-a, and RSA 485:14-b, which pertain to referendums and statements regarding public water supplies. The act is set to take effect 60 days after its passage.

The fiscal impact of this bill is significant, with the Department of Health and Human Services (DHHS) projecting an increase in expenditures of $1,000,000 to $3,000,000 per fiscal year due to the anticipated rise in demand for prescription fluoride supplements and treatment for tooth decay resulting from the cessation of water fluoridation. While some community water systems may see a reduction in costs associated with purchasing fluoride, the overall financial implications, particularly for Medicaid and public health, could be substantial. The Department of Environmental Services currently oversees compliance for fluoridated water systems, and the bill's passage would alter their operational responsibilities and financial dynamics.
