Somerset residents voted to discontinue fluoride treatment in their public water supply, but a state law requiring legislative authorization has left the community waiting as its exemption bill faces a January deadline.

A Massachusetts town’s effort to eliminate fluoride from its public drinking water remains stalled in the state House of Representatives, despite approval by local voters and the state Senate, raising questions about municipal authority over water treatment decisions.
Residents of Somerset, a southeastern Massachusetts community that has fluoridated its water since 1968, voted in May 2025 to discontinue the practice. However, state law does not provide an equivalent referendum procedure for communities seeking to end an established fluoridation program years after its implementation.
Unless lawmakers approve a special exemption, Somerset cannot enact the prohibition sought by residents. The legislation could expire when the current two-year legislative session ends on Jan. 5, 2027.
The controversy comes amid growing national debate over fluoride exposure, dental health and research examining potential neurological effects in children.
Democratic state Sen. Michael Rodrigues and Republican state Rep. Justin Thurber introduced Senate Bill 2627 to authorize Somerset to prohibit fluoridation through a local ordinance.
The Massachusetts Senate approved the measure April 30, and the House advanced it through its second reading May 18. However, the proposal remains before the House Committee on Bills in the Third Reading, which reviews proposed legislation for proper legal form before further action.
Under the state’s legislative procedures, the bill still requires additional House action before it can become law.
The proposed legislation would not automatically remove fluoride from Somerset’s water. Instead, it would grant local officials the authority to adopt an ordinance prohibiting the treatment.
Massachusetts’ Home Rule framework allows municipalities to petition state lawmakers for special legislative authorization when local actions conflict with existing state law.
Somerset pursued that process because the state’s fluoridation statute establishes a mechanism for challenging newly ordered treatment but does not expressly provide the same procedure for ending longstanding programs.
Under Massachusetts General Laws Chapter 111, Section 8C, local boards of health may order fluoride added to municipal water supplies.
Residents opposing a new fluoridation order must gather signatures from at least 10% of registered voters within 90 days of its publication. A successful petition triggers a referendum, and a majority vote against fluoridation prevents the board from imposing another order for at least two years.
The law does not establish a comparable procedure for residents seeking to reverse fluoridation decades after its original authorization.
Amesbury, Massachusetts, encountered a related dispute in 2011 after problems with fluoride treatment equipment led officials to suspend fluoridation. Residents subsequently opposed resuming the practice.
Attorneys discussing municipal fluoridation disputes have recommended pursuing special Home Rule legislation when existing state procedures do not provide a clear alternative.
Karen Favazza Spencer, a Massachusetts fluoridation opponent, criticized the delays involving Somerset’s petition, arguing that lawmakers were preventing residents from exercising local control.
“The state has created a legal trap where a community can vote to prevent fluoridation within 90 days of initiation, but is barred from voting to end it without state permission,” Spencer said.
She argued that Somerset had followed the Home Rule petition process but remained unable to implement its decision.
“This renders the Home Rule process a sham, offering municipalities a path that the state has no intention of letting any walk,” she said.
Somerset’s proposal is not the only fluoridation-related legislation awaiting action in Massachusetts.
Republican Sen. Bruce Tarr introduced Senate Bill 1630, which would establish a mechanism allowing municipalities to discontinue fluoridation. Lawmakers referred the measure to a study order in December 2025, a procedural action that frequently prevents proposals from advancing.
Other measures, including Senate Bill 1518 and House Bill 2549, would require health warnings in municipal water quality reports concerning potential risks associated with fluoride exposure.
The proposed warnings address possible neurological effects in young children and pregnant women, along with concerns involving certain health conditions.
A separate measure, Senate Bill 1517, would prohibit community water fluoridation statewide. Those proposals were also referred to study.
The legislative disputes reflect a broader national debate involving fluoride’s established dental benefits and research examining potential effects from higher exposure levels.
In September 2024, U.S. District Judge Edward Chen ruled in a lawsuit against the Environmental Protection Agency that fluoridation at 0.7 milligrams per liter, the concentration recommended by federal public health agencies, presented an unreasonable risk to children’s health under the Toxic Substances Control Act.
The case was brought by Fluoride Action Network, Mothers Against Fluoridation and Food & Water Watch.
The decision directed the EPA to address the identified risk under the Toxic Substances Control Act.
However, the Ninth U.S. Circuit Court of Appeals vacated the ruling in May 2026, finding procedural errors in the district court’s handling of the litigation and remanding the case for further consideration.
The appeals court did not resolve the underlying scientific dispute over fluoride exposure, but the vacated district court judgment is no longer operative.
A 2024 National Toxicology Program review found moderate-confidence evidence associating higher fluoride exposure, particularly drinking-water concentrations exceeding 1.5 milligrams per liter, with lower IQ in children.
That assessment did not establish that fluoridation at the recommended U.S. concentration of 0.7 milligrams per liter causes the same effects. Research into potential risks at lower exposure levels remains an active area of scientific debate.
Fluoridation opponents point to additional studies examining neurological outcomes, while dental health organizations continue to emphasize evidence that community water fluoridation reduces tooth decay.
The policy debate has already produced changes elsewhere in the country.
According to Fluoride Action Network, more than 80 communities and jurisdictions have discontinued fluoridation since the 2024 court decision.
That includes statewide prohibitions enacted in Utah and Florida, along with local restrictions such as a North Carolina county’s fluoridation ban.
For Somerset, the immediate issue remains legislative authority rather than a final determination of fluoride’s health effects.
Residents have already voted to discontinue treatment, and the Senate has approved legislation allowing the town to proceed. Yet without action by the House before the legislative deadline, Somerset’s effort could end without the exemption needed to carry out the local vote.
