Photographs showing artificial lakes along the Sawgrass Expressway in reclaimed wetland areas adjoining water-conservation areas in Broward County .......35 26. Maps showing hypothetical aquifer storage and recovery pressure buildup in the Upper Floridan aquifer using the Hantush-Jacob (1955) analytical model, assuming relatively high transmissivity and confining bed leakance or relatively low transmissivity and confining bed leakance .

The Floridan aquifer system in the southeastern United States is one of the most productive aquifers in the world (Miller, 1990). This aquifer system underlies an area of about 100,000 square miles in southern Alabama, eastern and southern Georgia, southeastern Mississippi, southern South Carolina, and all of Florida (fig. 1). The Floridan aquifer system is the primary source of water for nearly 10 million people and supports agriculture, industry, and tourism throughout most of the region. In most areas, water from this aquifer is potable and needs very little treatment before use. However, in southern Florida (south of Lake Okeechobee), northwestern Florida and southern Alabama and Mississippi (Pensacola and westward), and eastern South Carolina, water in the aquifer system generally is not potable. Ginnie Springs (near Gainesville, Florida) is a popular swimming spot during the summer months.
