Abstract
Drought conditions in southwest Georgia can detrimentally impact agricultural communities and their available water supply. Source-switching to deeper aquifers in drought events can provide an alternative water resource, however, uncertainty exists in the geology and hydrogeology of these aquifer systems. In this study, a three-dimensional hydrostratigraphic model was constructed by collecting pre-existing wells in southwest Georgia. This model was similar to two-dimensional hydrostratigraphic correlations in previous studies, however, some changes were recognized in the areal extent of the Claiborne aquifer. Areas of thinning could also be depicted and provided insight into what sites could be more susceptible to leakage between aquifer systems. It is supported that the three-dimensional hydrostratigraphic model can be used in the characterization of wells to aid in the further development of understanding the geologic and hydrogeologic framework in southwest Georgia.
