iLITH is an Indiana Geological and Water Survey (IGWS) database containing information from water-well records provided by the Indiana Department of Natural Resources (IDNR), Division of Water. These records contain both locational and lithologic data edited by the IGWS (Brown and others, 2000). The locational information was verified and the lithologic information was standardized into a series of tables, separating information such as color, hardness, texture, consistency, and simplified sediment type (the "interpreted" field).

The interactive map portion of this website displays the point data for the 4,719 water wells in Marion County that are contained in iLITH (fig. 1). The location and lithology data for each well can be viewed by clicking on any water well in the Web viewer using the information tool. The locational and lithologic information will open in a report format.
