A Geographic Information System (GIS) application named WELLHEAD is described. It integrates geographic data on highways, townships, and hydrography on flowing and standing water and wetlands with geographic subsurface information from drilling logs and strata samples. To illustrate the application and utility of WELLHEAD, data from Dane County, Wisconsin has been used to allow hydrogeologists, geologists, geotechnical engineers, and water chemists pursuing pollution control strategies to retrieve and view subsurface data in graphical form. Interactive options allow users to display information in different perspectives.
