“…Ground-water temperature and geochemical data from the Lower Floridan aquifer in the south Florida area suggest that a geothermally driven circulation of ground water occurs in the Lower Floridan aquifer in that area (Kohout, 1965;Meyer, 1989;Sanford and others, 1998). In this circulation, cold, dense ocean water enters the Lower Floridan aquifer where it is in direct contact with the ocean.…”

“…2). Kohout 25 hypothesized that the LFA south of Lake Okeechobee is recharged by coastal sea water entering the aquifer from near the bottom of the Straits of Florida at a depth of about 600 m. This water flows inland beneath the discharging UFA fresh water in the highly permeable section of the LFA referred to as the Boulder Zone. The density difference between sea water and discharging fresh water alone would be sufficient to cause cyclic flow of groundwater in coastal aquifers 26 .…”

. Here we show that the geochemistry of the groundwater found in the Floridan Aquifer System in south Florida is best explained by a reorganization of groundwater flow following the sea-level rise at the end of the Last Glacial Maximum approximately 18,000 years ago. We find that the geochemistry of the fresh water found in the upper aquifers at present is consistent with recharge from meteoric water during the last glacial period. The lower aquifer, however, consists of post-sea-level-rise salt water that is most similar to that of the Straits of Florida, though with some dilution from the residual fresh water from the last glacial period circulation. We therefore suggest that during the last glacial period, the entire Floridan Aquifer System was recharged with meteoric waters. After sea level rose, the increased hydraulic head reduced the velocity of the groundwater flow. This velocity reduction trapped the fresh water in the upper aquifers and initiated saltwater circulation in the lower aquifer.

“…The highest transmissivity reported in the county (1.5 x 10 6 ft 2 /d) was from an aquifer test run on an injection well (32F) completed in the Boulder Zone (Kohout, 1965)--a zone within the Lower Floridan aquifer consisting of high permeability, fractured, and cavernous dolomite near the base of the Oldsmar Formation. The Boulder Zone at that site occurs at a depth interval of about 2,400 to 3,000 feet.…”
