Saltwater Intrusion

Zone of dispersion in the Biscayne aquifer
Zone of dispersion in the Biscayne aquifer near Miami, Florida

Chloride concentrations in the thick zone of dispersion (shown by the lines of equal chloride concentration) range from that of freshwater containing 16 parts per million to that of sea water containing 19,000 parts per million. (Figure modified from Kohout, F.A., 1964, The flow of fresh water and salt water in the Biscayne aquifer of the Miami area, Florida: U.S. Geological Survey Water-Supply Paper 1613-C, p. 12-32).
