Aquifer Transmissivity Values in Indiana

Basic Information
Author: Naylor, Shawn and Levy, Paul
Description:This file is a digital geospatial point coverage of transmissivity values calculated for the Kankakee River Basin, the Lake Michigan Region, the Maumee River Basin, the West Fork of the White River Basin, and the Whitewater River Basin in Indiana. The following was exerpted from IDNR metadata: "The method of calculation varies between the Theis method for detailed analysis of pump tests, and transmissivity determined from specific capacity data for domestic wells. The specific capacity data were derived from water well logs." AQUIFER_TRANSMISSIVITY_IDNR_IN.shp is intended for display and/or analyses requiring spatially distributed point values of aquifer transmissivity for the Kankakee River Basin, the Lake Michigan Region, the Maumee River Basin, the West Fork of the White River Basin, and the Whitewater River Basin. These transmissivity estimates have utility for geothermal heat pump installers designing open loop ground-coupled systems since the performance of injection wells is dependent upon the transmissivity of the aquifer in which the well is screened. This shapefile was produced by the Indiana Geological Survey as part of an effort to populate the National Geothermal Data System (NGDS) with data in a digital form.
