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.

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.

Sinkholes from subsidence event, Florida, February 1998
Sinkholes from subsidence event, Florida, February 1998. Over 700 sinkholes formed over a 20-acre area in response to well drilling. A well had been drilled about 20 feet into a cavity, when air-lift well-development methods began being used. Immediately after, small sinkholes started appearing in the surrounding area. Subsidence continued for several hours, with sinkholes closest to the well expanding to become the largest in the area.

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.
