Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater systems in karst systems. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of Conservation (TDEC) was formed to investigate karst spring systems across the state utilizing fluorescent groundwater tracing, particularly in areas where these resources may be used as drinking water sources. In fall 2021, USGS and TDEC staff identified possible vulnerabilities or complexities that may exist within karst spring systems...

The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

In karst areas there is an inherent connectivity between surface streams and groundwater resources, thus activities which occur in these areas can influence the quality and quantity of groundwater. The Calfkiller River in central Tennessee drains the western escarpment of the Cumberland Plateau and is one of the densest areas of karst development in the state. The perennial flow of the Calfkiller River is supplied by karst springs which create conditions suitable for two endangered species, the Cumberland pigtoe mussel and the bluemask darter fish. Both species are reliant on clear, freeflowing, high-quality headwater streams as their primary habitat. The bluemask darter has been extirpated from the Calfkiller River,...

The Barrens topminnow (Fundulus julisia) was listed as an endangered species on October 21, 2019 (84 FR 56131). The species faces severe threats from predation by the western mosquitofish and habitat alteration, exacerbated by climate change (USFWS, 2019a). Benedict Spring, which discharges from Summitville Mountain Cave, is the type locality for Barrens topminnow (Williams and Etnier, 1982). A top priority recovery effort is to protect the watersheds supplying groundwater to the habitat. A common method for investigating and monitoring potential threats to an aquatic species and their habitats is by delineating a topographic drainage area surrounding the habitat. In karst landscapes water sinks directly into the...
