Characterization of groundwater flow and transport in the General Separations Area, Savannah River Plant: Effect of groundwater withdrawals on the Tuscaloosa-Congaree aquifer head reversal in H Area. Final report
- GeoTrans, Inc., Herndon, VA (United States)
The Savannah River Plant (SRP) has maintained a number of sites used for land disposal of various waste materials. The General Separations Area at SRP, located between the Upper Three Runs and Four Mile Creeks, has served as an active area for waste storage for about thirty years. The Tuscaloosa aquifer, which lies beneath the General Separations Area, is a water source for SRP and the surrounding area. The isolation of the Tuscaloosa aquifer has been maintained by an upward hydraulic gradient from the Tuscaloosa aquifer to the overlying Congaree aquifer. This upward gradient is referred to as a hydraulic head reversal in the General Separations Area, i.e., hydraulic heads in the upper Tuscaloosa are higher than hydraulic heads in the Congaree. This head reversal has declined in recent years due to increased groundwater pumping in the upper and lower Tuscaloosa formations. The objective of this investigation is to assess the effects of pumping within the General Separations Area on the Congaree/upper Tuscaloosa head reversal. Methods of maintaining future Tuscaloosa aquifer isolation through the optimization of groundwater withdrawal location and rate were studied. Steady-state and transient groundwater flow models were used to characterize past and potential future groundwater conditions. Future groundwater conditions were simulated for a variety of pumping scenarios.
