In 1984 and 1985, a quasi three-dimensional groundwater flow model was developed for the A/M Area (Savannah River Laboratory Complex) of the Savannah River Site to assist in the design of a groundwater recovery well network to remediate groundwater contaminated with chlorinated hydrocarbon solvents. In 1986, the existing groundwater flow model was used to evaluate the effectiveness of groundwater remediation systems. Since the original model was developed, additional monitoring wells have been installed, the understanding of the hydrogeologic system has improved and the horizontal and vertical extent of the contamination in the groundwater systems has been better defined. The objective of this study is to update and improve the existing A/M Area groundwater flow model by incorporating recent hydrologic information. The new model is calibrated to 1989--1990 groundwater levels and surface water flows. The model area is approximately 31 square miles and encompasses a manufacturing and processing area designated the A/M Area, a previous waste effluent disposal basin and overflow to a natural depression (Lost Lake), and several surface water features. The simulations are run on 80386-based personal computer using the public-domain groundwater flow code MODFLOW. This calibrated coarse-grid model is a base model. Specific areas of interest can be further discritized to provide more detailed and accurate water level elevations for use in particle tracking and capture analysis. The particle tracking and capture analysis are used to evaluate the groundwater contamination capture and removal capacity of proposed recovery wells.
