House Bill 929 would prohibit the addition of fluoride or fluoride-containing chemicals to public water systems in North Carolina. The bill amends the state public health law to define the “introducing or depositing” of fluoride into a public water system as a prohibited act, while carving out exceptions for naturally occurring fluoride in water sources and for industrial or manufacturing uses unrelated to public water treatment.
The bill is framed as a public health measure, but its practical effect is to end community water fluoridation by public systems if enacted. It would take effect on January 1, 2026, and would apply statewide to water utilities and other persons involved in water treatment practices covered by the statute.
HB929 would amend G.S. 130A-325 by adding a new prohibited practice related to public water systems. It would change the legal authority of water systems and treatment providers by barring intentional fluoride addition to drinking water, while preserving exceptions for naturally occurring fluoride and non-public-water industrial uses. The bill would affect municipal and regional water utilities, public health policy, and residents served by fluoridated systems.
Based on the bill text and the absence of recorded committee debate or votes in the provided materials, the available record shows no formal opposition or support statements. The bill’s title and findings present it as a public health bill, but the substance is controversial because it would eliminate a long-standing water fluoridation practice used by many communities. The referral status suggests it was still at an early stage in the legislative process.
The main point of contention is whether fluoride should be added to public drinking water at all. Supporters are likely to argue the bill protects public health, personal choice, or limits chemical exposure, while opponents would likely view it as undermining dental health and established public health practice. The bill also raises practical concerns for water utilities and local governments that currently fluoridate water, since they would need to stop the practice if the bill became law.
