Description: This map from the U. S. Geological Survey Professional Paper 1403-1 shows the chloride concentrations in milligrams per liter in water from the upper 200 feet of the Floridan aquifer system, current to 1989. The diagonals show less than 250 mg/l, the light shaded area shows 250-1,000 mg/l and the dark shaded area shows greater than 1,000 mg/l. The upper 200 feet consists mostly of either Ocala or Suwannee Limestone. The main source of chloride is seawater.
