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.

Main Barton Spring, with Barton Springs Pool drained Main Barton Spring, with Barton Springs Pool drained. USGS Research Hydrologist Barbara Mahler makes water-quality measurements of Main Barton Spring. The spring normally discharges under the presssure of 12 feet of overlying water, but here that water had been lowered temporarily, to quantify the water-quality changes it causes.

Fluorescent tracer injection into a sinkhole in the Leetown area, WV Fluorescent tracer injection into a sinkhole in the Leetown area, WV. Tracer tests were conducted as part of intensive investigations of the hydrogeology, water quality, and groundwater flow of the karst aquifer in the Hopewell Run Watershed, northern Shenandoah Valley, near Leetown, West Virginia.

This website allows you to browse for karst reports and articles authored by USGS researchers, and find links for other karst resources. There is also an overview of karst and its properties.

This website is maintained by members of the USGS Karst Interest Group, whose (KIG), who investigate karst across the United States.
