With the backing of Agriculture Commissioner Wilton Simpson, a Senate Republican on Thursday filed a wide-ranging bill that would bar public water systems from adding fluoride to water supplies.

Local governments in Florida and across the country recently have debated — and, in some cases, stopped — the longstanding practice of adding fluoride to water supplies. Florida Surgeon General Joseph Ladapo has urged more communities to take that step, appearing personally at a hearing in Tavares late last year as the city halted the practice.

The proposal would bar public water systems from adding fluoride to the water supply, but naturally occurring fluoride is already in JEA’s drinking water.
