Geohydrology and susceptibility of major aquifers to surface contamination in Alabama; area 1

Each of the aquifers is recharged throughout its outcrop in the study area and is susceptible to contamination within the outcrop.Generalized topographic settings such as closed-contour depressions are identified as afeas that are highly susceptible to contamination.Specific features such as sinkholes also are identified as extremely susceptible to contamination.
