The Savannah River Site (SRS) has accumulated a wealth of groundwater geochemistry data during the past two decades from a large network of monitoring wells. These data, archived in an Oracle database, have been accessible only in quarterly reports or a spreadsheet format. An ArcView extension has been developed to extract the data using a simple interface. The data are filtered, processed, and returned as an ArcView theme, permitting rapid analysis and evaluation of contaminated areas.Typically, these data must be analyzed by hydrostratigraphic unit to be useful. Unfortunately, a compendium of well screen-versus-aquifer relationships for groundwater monitoring wells at SRS has not been available, making the geochemical data difficult to use and analyze. Therefore, a 3-D hydrostratigraphic model has been developed in geographic information systems (GIS) and used in conjunction with well construction data to determine the location of well screen zones within the SRS vertical hydrostratigraphy. This information has been incorporated into the ArcView extension so that geochemical data can be analyzed and displayed in ArcView by hydrostratigraphic unit.
