Description: This is a map showing general trends in the sulfate concentration in water from the upper part of the Floridian Aquifer in Florida, current to 1975. The following is taken from the article "Sulfate Concentration in Water from the Upper Part of the Floridian Aquifer in Florida" by William J. Shampine — "The Floridian Aquifer, which underlies all of Florida, yields water with a sulfate content of less than 50 parts per million in the northwestern part and throughout most of the center of the state. In the Southern part of Florida and along most of the east coast, the sulfate concentration generally exceeds 100 parts per million and is as much as 1,700 parts per million." The key shows parts per million of sulfate; yellow means less than 50, green is 50-100, blue is 101-250 and pink is greater than 250. 1 part per million is 17.1 grains per gallon and that is 1 milligram per liter. Please see the article Sulfate Concentration in Water from the Upper Part of the Floridian Aquifer in Florida by William J. Shampine for more information.
