The Tertiary limestone aquifer system of the southeastern United States is a thick sequence of carbonate rocks that range from Paleocene to Miocene in age and are hydraulically connected in varying degrees. The upper permeable zone of the aquifer system consists of the Tampa, Suwannee, Ocala, and Avon Park Limestones. Based on analyses of water samples from 591 selected wells, a map is presented which shows dissolved-solids concentration in ranges of 0-250, 251-500, 501-1,000, and greater than 1,000 mg/. Dissolved-solids concentrations and hydrochemical facies developed within the aquifer system are related to the predevelopment and modern-day ground-water flow system. (USGS)
