Geohydrology and susceptibility of aquifers to surface contamination in Alabama; area 5

The U.S. Geological Survey, in cooperation with the Alabama Department of Environmental Management, is conducting a series of geohydrologic studies to delineate the major aquifers and their susceptibility to contamination in Alabama. This report delineates and describes the geohydrology and susceptibility of the major aquifers to contamination in Area 5--Chambers, Clay, Cleburne, Coosa, Lee, Randolph, and Tallapoosa Counties. Little groundwater is used for public water supplies in Area 5. Groundwater withdrawals for public supply in 1985 were 0.88 million gal/day. Most cities and towns that formerly used groundwater presently use surface water. None of the sedimentary rocks or unconsolidated deposits is tapped by public supply wells. None of the igneous and metamorphic rocks are considered a major aquifer because of low yields. Aquifers in the study area are susceptible to surface contamination throughout their entire outcrop area. Areas that are highly faulted and valley areas where groundwater is at or near land surface have potential to be highly susceptible to surface contamination. (USGS)
