The timeline
| Date | What happened |
|---|---|
| May 6, 2025 | Miami-Dade approves County Resolution R-370-25 |
| May 15, 2025 | Florida Senate Bill 700 approved by the Governor |
| June 6, 2025 | WASD's three regional plants stop adding fluoride |
| July 1, 2025 | The state law takes effect |
The statute, section 403.859 of the Florida Statutes, prohibits using any additive in a public water system that does not meet the definition of a water quality additive.
Why the 2025 report still shows 1 ppm
WASD's 2025 report summarizes the whole year, so its fluoride line still shows 1 ppm (range 0.1 to 1) from the months before the change. A footnote explains that after fluoridation stopped, main system levels ranged from 0.1 to 0.3 ppm, from fluoride naturally present in the soil and the Biscayne Aquifer.
Reducing fluoride at home
- Reverse osmosis: the membrane rejects most dissolved minerals, including fluoride.
- Activated alumina: a specialty medium whose performance depends on contact time and pH.
- Ordinary carbon: most pitchers, fridge filters and whole-home carbon systems are not designed for fluoride.
Check that the exact model is certified for fluoride reduction, typically under NSF/ANSI 58 for RO.
RO in a Sweetwater kitchen
Living Water's under-sink alkaline RO is a multi-stage system with a dedicated faucet and a final stage that adds minerals back. It fits apartments, condos and houses. Ask Jorge for the specific model's certification listing to confirm its reduction claims. Compare designs in alkaline vs. standard RO.
Why not a whole-home system for fluoride
Whole-home systems are built around carbon for chloramine, taste and odor. Reducing fluoride across every shower and toilet would take a much larger and more complex system for little practical benefit, since fluoride concerns center on what you drink. Treating the kitchen tap with RO is the targeted approach, and many households pair it with a whole-home filter for chloramine.
Infant formula, cooking and coffee
RO water at the kitchen tap covers the uses people ask about most: drinking, cooking, coffee and preparing formula. Questions about fluoride and a baby or child belong with your pediatrician or dentist; this page does not take a position for or against fluoride.
