摘要：	Transportation of hazardous material or potential environmental contaminants presents the potential for spill or accidental releases to surface or groundwater resources The use of a Geographical Information System (GIS) to locate transportation routes as well as springs, wells and surface water bodies offers the opportunity for tracking and monitoring the effects of accidental releases from transported waste in the case of an overturned truck. The four-county area of Washington. Madison, Benton, and Carroll counties in Northwest Arkansas was chosen for this GIS demonstration project Previous work by the University of Arkansas Department of Geology and the Center for Advanced Spatial Technology (CAST) provided base maps including springs, wells, and surface water bodies in the four-county area. In addition, TIGER/Line data were readily available for locating transportation routes The Intergraph software, GeoMedia was chosen to manipulate the data because the Arkansas Highway and Transportation Department currently uses GeoMedia for GIS applications The following report includes descriptions of data manipulation, layer construction, computer code, and a basic tutorial for the results of this research. The resulting product is the ability to call up a region, and either “point and click” on a particular location, or to input Universal Transverse Mercator (UTM) coordinates of a location. The software w ill locate the mapped water resources within a specified radius of those points
