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.

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.

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.
