Description: This map from the U. S. Geological Survey Water Resources Investigation Report number 93-4158, Hydrology and Simulated Effects of Groundwater Withdrawals for Citrus Irrigation, Hardee and De Soto Counties, shows the areas in Hardee and De Soto counties of upward and downward leakage through the lower confining unit of the intermediate aquifer system in September, 1988. The intermediate aquifer system underlies all of Hardee and De Soto counties and is hydraulically separated from the underlying Upper Floridan aquifer by the lower confining unit. For most of the study area the lower confining unit retards hydraulic interaquifer flow, however, it does transmit, or leak, water downward from the intermediate aquifer, and upward into the intermediate aquifer, and the system is referred to as a leaky-aquifer system.
