The surficial aquifer system at the Wormsloe State Historic site has the potential to serve as an alternate groundwater source for non-potable water needs in Georgia. This study integrates ground penetrating radar (GPR), digital elevation model (DEM) derived from Light Detection and Ranging (LiDAR), hydrograph data, and porosity estimates to evaluate the total water storage and change in storage. The GPR data mapped the depth to the confining layer and the water table depth. The magnitude of seasonal fluctuations in hydraulic head was extracted from hydrograph data. These datasets were used to construct a water table elevation map for two seasonal conditions. Porosity estimate from the repacked samples was integrated and used to compute total water storage and the changes in storage. This study shows that the surficial aquifer is an alternate groundwater source but limited by seasonal fluctuation in water storage and lateral and inland saltwater intrusion.
