Fluoride in Florida well water
In Florida, <1% of 33,748 tested private well samples exceeded the EPA limit for fluoride (4 mg/L).
Natural fluoride in bedrock wells can exceed the limit. Above 4 mg/L long-term exposure causes skeletal fluorosis; above 2 mg/L children can develop tooth mottling.
Check your fluoride number
Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
Test your Florida well for fluoride
Certified lab analysis of your own tap water, bottles and prepaid return shipping included. The Essential well panel covers arsenic, uranium, nitrate, lead, copper, manganese, iron, sodium and bacteria; radon and PFAS are add-ons.
