Summary:Ground water in DeSoto and Hardee Counties, Florida, is obtained from a surficial aquifer, which is principally fine sand, and the Floridan aquifer, which consists of two limestone-dolostone units. Average transmissivity of the surficial aquifer is 1,300 feet squared per day, and transmissibity of the combined upper and lower units of the Floridan aquifer is as high as 270,000. Seasonally, the potentiometric surface fluctuates as much as 30 ft. From 1949 to 1973, net declined throughout the area ranged from a few feet to 20 ft. Data from a citrus-grove well field with a pumping capacity of 86 million galons per day indicate drawdowns 5 mi from the grove center will be about 5 ft at the end of each spring pumping period. Water levels will recover during summer non-pumping periods. Water from the upper unit of the Floridan aquifer generally has alower mineral concentration than water from the lower unit. In parts of both counties, concentrations of sulfate, chloride and fluoride exceed limits recommended for drinking water. Ground-water withdrawals averaged 94 million gallons per day in 1970: about 96 percent was for irrigation purposes. Several water-management techniques are hydrologically feasible. (Woodard-USGS)
