Community water fluoridation in FL

State- and county-level aggregates from CDC's Water Fluoridation Reporting System. Per-utility fluoridation status is not in the bulk dataset; for a specific system, see the link below.

FL no longer adds fluoride to public water

Under Florida SB 700 (Florida Farm Bill), effective July 1, 2025, public water systems in FL may not add fluoride to drinking water. The CDC figures below are historical and describe fluoridation before the ban; naturally occurring fluoride in source water is unaffected.

Per-system data predates the ban

FL stopped adding fluoride statewide on July 1, 2025 under Florida SB 700 (Florida Farm Bill). CDC's per-system listing reflects status before the ban, not current fluoridation. For the latest measured fluoride at a specific address, see that utility's annual water quality report.
