GIS Modeling of Ground-water Contamination at the Savannah River Site

Numerical simulation models are routinely used to predict the fate and transport of ground-water contaminants. These models rely on estimates of aquifer hydraulic properties instead of historical information because long-term water quality data are generally lacking. The Savannah River Site is unique in that a long-term, water-quality record is available for use in building a spatially explicit water quality model. In this paper we outline a plan to employ Geographic Information System (GIS) mapping techniques to represent the current and historical water quality conditions at two locations (the General Separations Area and the A/M area) at the Savannah River Site. We also propose to identify relationships between water quality parameters, leading to a better understanding of ground-water contamination trends.
