U.S. Geological Survey Hydrologist, Janet Carter, demonstrates an interactive groundwater-flow model to the Field Affair class at the South Dakota School of Mines and Technology on June 19, 2012, in Rapid City, SD. The model can be used to show how a contaminant can travel through an aquifer to a pumping well.
