Description: This map from the U. S. Geological Survey Professional Paper 1403-1 shows the total hardness of water in milligrams per liter from the Upper Floridan aquifer, current to 1989. The diagonals show 0-60 mg/l, the light shaded area shows 61-120 mg/l, the medium shaded area shows 121-180 mg/l and the dark shaded area shows greater than 180 mg/l. The total hardness does not have much geochemical significance, but is important for some water uses.
