Open-File Report 78-881
Prepared in cooperation with The Florida Keys Aqueduct Authority

The utilization of the Floridan aquifer as a source of potable water has increased. The use of the Floridan aquifer for subsurface storage of freshwater, and as an industrial water supply in Dade and Monroe Counties, is being considered by water management authorities and some industries.

Information on locations, depths, casings, and year drilled for 67 wells that penetrate the Floridan aquifer in Dade and Monroe Counties is presented to assist in planning future uses of the Floridan.

Chloride concentrations in water from wells ending in the Floridan aquifer in Dade County ranged from 1,200 to 9,000 milligrams per liter. In Monroe County the chloride concentrations ranged from 1,600 to 20,000 milligrams per liter.

Water levels were measured in selected wells to determine the altitude of the potentiometric surface. The measurements indicate that the 40-foot potentiometric line extends from southern Dade County to the upper Florida Keys.
