Interim report on the ground-water resources of Manatee County, Florida
1955
Peek, Harry M. | Anders, Robert B.
A large part of western Manatee County is devoted to the growing ofwinter vegetables and citrus fruits. As in most of peninsular Florida,rainfall in the county during the growing season is not sufficient for cropproduction and large quantites of artesian water are used for irrigation.The large withdrawals of artesian water for irrigation result in a considerabledecline of the artesian head in the western part of the county. This seasonaldecline of the artesian head has become larger as the withdrawal of artesianwater has increased. The lowering of the fresh-water head in some coastal areas in the Statehas resulted in an infiltration of sea water into the water-bearing formations.The presence of salty water in the artesian aquifer in parts of the coastal areaof Manatee County indicates that sea water may also have entered the waterbearingformations in this area as a result of the decline of artesian pressureduring the growing season. The purpose of the investigation is to make a detailed study of the geologyand ground-water resources of the county, primarily to determine whethersalt-water encroachment has occurred or is likely to occur in the coastal area.
