Board votes to end fluoride addition to county drinking water; orders administrative steps and limited notification

Miami-Dade County commissioners on Thursday voted to end the practice of adding fluoride to drinking water supplied from county treatment plants, a policy change the board said is intended to give residents freedom of choice while the science is further examined.

The measure — introduced by Commissioner Alex Gonzalez — passed after multiple amendments that limited how water department funds could be used for public outreach and clarified the county’s contractual obligations to wholesale customers.

The debate: The item drew a long public comment period and an extended commission debate. Hundreds of residents and dozens of medical and dental professionals spoke for and against continuing fluoridation, citing a mix of public-health, ethical and scientific arguments.

- Proponents of removal argued the latest research raises safety questions for pregnant women and young children and said fluoride’s proven topical benefit (toothpaste, professional dental treatments) reduces the need for mass medication via water supply. Commissioner Gonzalez told the board, “The choice before us is not about politics. It is about prudence, public health, and the principle of protecting those who cannot protect themselves.”

- Opponents, including county water managers and some medical groups, argued that fluoridation of community water supplies remains widely supported by major public-health organizations and that removing fluoride could increase dental decay, particularly in underserved populations.

Administrative directions passed alongside the core vote - Contracts and notice: County counsel and staff were directed to identify and review any contract language with wholesale customers and notify those municipal customers; counsel advised boards that some wholesale agreements could require notice and that the county needed to confirm there are no contractual obligations that would preclude immediate discontinuation. - Operational timeline: Water department staff told commissioners the mechanical process of stopping fluoride can be done promptly; commissioners asked staff to inventory existing fluoride supplies and report back on logistical and budgetary effects. - Messaging and funds: Commissioners amended the motion on the floor to remove a broad county-funded public outreach campaign paid from water-department (WASDE) funds. The board discussed lower‑cost notification options (for example, notices on water bills) and asked administration to pursue low-cost direct notices rather than an expensive media campaign paid with utility-restricted funds.

Financial and implementation notes - County staff and commissioners discussed the immediate and ongoing cost impacts. Miami-Dade Water and Sewer Department managers noted that the county currently incurs recurring costs tied to fluoridation systems and that a previous internal estimate for savings ranged from several hundred thousand dollars annually to larger figures depending on accounting scope; the board did not reallocate restricted WASDE bond funds for a full outreach campaign. - Legal exposure: The county attorney advised the board to review existing wholesale contracts; commissioners were told that discontinuing fluoride for customers supplied by county plants may be contractually straightforward for many municipal customers but could require negotiation or notice in others.

How the board voted: After amendments, the board passed the resolution by voice vote. The final motion as approved instructs the mayor to stop adding fluoride at county treatment plants for county-supplied water customers, review contracts and notice requirements with wholesale customers, inventory existing fluoride supplies and injection equipment, and to provide a report back to the commission on implementation details.

Speakers - Commissioner Alex Gonzalez, mover (sponsor of the removal resolution). - Surgeon General (Florida) Dr. Joseph Ladapo, present and offered remarks on prudence and risk. - Chief Roy Coley, Water and Sewer Department (department head who confirmed the department can stop dosing quickly). - Numerous public speakers, pediatric dentists and community advocates on both sides of the question (public comments were extensive).
