Ground water may be flowing beneath and transverse to the Savannah River (trans-river flow) in the vicinity of the Savannah River Site (SRS) within the Coastal Plain aquifers in South Carolina and Georgia. The hydrologic system of the Coastal Plain physiographic province in South Carolina and Georgia is comprised of a complex wedge of fluvial, deltaic, and marine sedimentary deposits. Rural and industrial areas with known sources of ground-water contamination, including a nuclear processing and disposal facility, are located in the Savannah River drainage basin. The possible migration of contaminants under the Savannah River into ground-water supplies has caused concern about public health and the environment. The US Geological Survey (USGS), in cooperation with the US Department of Energy and the Georgia Department of Natural Resources, is evaluating trans-river flow in the vicinity of the Savannah River Site under pre-development, present, and hypothetical development conditions. Results of the study may be used as a guide in water-resources management in the basin. Simulation of the ground-water flow system using the USGS three-dimensional, finite-difference model (MODFLOW) under steady-state and transient conditions is expected to identify areas with the greatest potential for trans-river flow, and guide the development of higher resolution sub-regional or localized models. Model boundary conditions will include natural hydrologic flow boundaries, where available, and head-dependent and specified head boundaries where natural hydrologic boundaries are not present.
