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...
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.

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.

Vendome Well Vendome Well. A flowing artesian well in the Chickasaw National Recreation Area. A water sample from Vendome Well was determined to be 9,000 years old by carbon-14 dating. (Photo by Scott Christenson) Read more about the Arbuckle-Simpson aquifer...
Turner Falls Turner Falls. The largest waterfall in Oklahoma. Springs discharging from the Arbuckle-Simpson aquifer into Honey Creek are the source of water to Turner Falls. (Photo by Noel Osborn, Ok. Water Resources Board) Read more about the Arbuckle-Simpson aquifer...

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.
