Dye tracing investigations were conducted in Cades Cove and Tuckaleechee Cove, two carbonate fensters in the western Great Smoky Mountains. These investigations were conducted as part of a two-year study examining the karst hydrology in the carbonate fensters. Main objectives of the dye tracing investigations were to determine resurgences for cave systems, delineate recharge areas for major springs, and to compare travel times from sink (dye injection point) to resurgence (monitoring site) for the two coves. Over the two-year study period (2017-2018), four different rounds of dye injections were completed, and each round had four dye injection locations, with the exception of the fourth round in September 2018,...

The U.S. Geological Survey, in cooperation with the Tennessee Department of Transportation, conducted an investigation of acid-rock drainage from road cuts in Tennessee during 2014-2015. The Devonian Chattanooga Shale contains disseminated pyrite and is a primary producer of acid-rock drainage (ARD) in Tennessee. One objective of the overall investigation was to attenuate ARD by manipulating the indigenous microbial community through different treatment injections. The scope of the study included establishing flow-through microcosms constructed with shale from the Chattanooga Shale formation rich in pyrite collected from an ARD site in Middle Tennessee. The microcosms were subjected to various treatments and evaluations...
