Karst and the USGS

Welcome to the USGS Karst Website. This website presents information on USGS research on karst aquifers, which are a vital groundwater resource in the United States. Here you can learn about past and current USGS karst research, with information on ongoing studies, publications, and key contacts for major karst areas. Click on an aquifer on the map below, or select one from a list of aquifers.

Streamflow tracer test on a tributary to Hopewell Run near Leetown, WV Streamflow tracer test on a tributary to Hopewell Run near Leetown, WV. U.S. Environmental Protection Agency scientist Malcolm Field conducts this test. It was conducted to assess potential leakage of stream water to the karst aquifer in the northern Shenandoah Valley of West Virginia.
