Aquifers

South Dakota School of Mines and Technology and the West Dakota Water Development District

The Black Hills Aquifer Mapping project is producing a series of maps showing the accessibility, susceptibility, and vulnerability of ground water sources (aquifers) in and near Rapid City, South Dakota.  The maps are based on detailed geologic and structural mapping of 1:24,000 quadrangles, inventories of wells and septic systems, and geographic information system (GIS) analysis.

 The maps are being distributed in PDF format, allowing them to be viewed in a standard Adobe Reader program.  Users can also zoom in/out and turn individual layers on and off.  

This project is being funded by the West Dakota Water Development District.  We would also like to thank the South Dakota Geological Survey and the South Dakota Department of Transportation for sharing GIS data for the project.
