I am a licensed water treatment operator in Ohio. Flourine is not used in potable water. Fluoride is used and has been proven to be benificial for teeth in the appropriate doses. In Ohio the Fluoride residual is required to be monitored at least once per shift and at least once per day in the distribution system. The fluoride residual should be 1 mg/l and can range form .8 to 1.3 mg/l with out being in violation. If you took 8.34 pounds of pure fluoride and dissolved it in 1,000,000 gallons (Thats one million) of water you would have a residual of 1 mg/l fluoride. And depending on where in the country you live chances are you have naturally occuring fluoride in your water anyways. Here in central Ohio it averages about 0.38-0.55 mg/l of flouride found in raw water. In some areas out west it may be over 4 mg/l raw fluoride
