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.

Sinkhole-formed lakes near Winter Haven, FL Sinkhole-formed lakes near Winter Haven, FL. These sinkholes, which often are filled with permeable surficial sands, provide more direct avenues for water from the surficial aquifer system to recharge the underlying Upper Floridan aquifer. (from Spechler and Kroening, 2006) Read more about the Upper Floridan and Biscayne aquifers...

Loss of water from the Peace River through underlying conduit during low-flow period, May 2004 Loss of water from the Peace River through underlying conduit during low-flow period, May 2004. The Peace River in this area is characterized by shallow, sometimes exposed carbonate units, with karst features that vary in type and size and include sinkholes, subsidence depressions, dissolution pipes, and enlarged fractures.

Karst conduit in a borehole, Cumberland County, PA Karst conduit in a borehole, Cumberland County, PA. A still-frame from a video taken from a camera lowered into a borehole in karst terrane. A conduit appears in this photo as a distinctive void space, which likely transmits large volumes of water through the aquifer rapidly.

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. (Photo by Carol Boughton) Read more about karst aquifers of the Valley and Ridge, Piedmont, and Blue Ridge province...

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.
