Description: This map from the U. S. Geological Survey Professional Paper 1403-1 shows the fluoride concentrations in milligrams per liter in water from the Upper Floridan aquifer, current to 1989. The diagonals show less than 0.5 mg/l, the light shaded area shows 0.5 to 0.99 mg/l, the medium shaded area shows 1.0 to 1.49 mg/l, the medium-dark area shows 1.5 to 1.99 mg/l and the dark area shows equal to or greater than 2.0 mg/l. The largest source of fluoride is water recharging the aquifer system in the freshwater parts.
