Groundwater Flow Tracing in Carter Saltpeter Cave and Toll Branch, Carter County, TN
by Doyka, Aaron G., M.S., East Tennessee State University, 2017, 96; 13830166
Abstract (Summary)

Groundwater tracing studies have shown a well-developed conduit system in the karst aquifer beneath the Buffalo Creek Watershed of Carter County, TN. Groundwater can quickly travel beneath topographic divides, transporting contaminants. Using GIS and field reconnaissance, two sites were selected for a two phase dye trace study. In May-June 2016 groundwater resurgences were located using activated carbon samplers, and in October-December 2016 flow velocities were measured using ISCO automatic water samplers. In study 1, a stream sinking in the back of Carter Saltpeter Cave was traced to its resurgence at Cave Springs Cave. In study 2, the dye mass centroid passed the resurgence 23.2 hours after injection. During study 1, dye injected into a sinkhole near the headwaters of Toll Branch rapidly diffused into multiple conduits. In study 2, dye from the Toll Branch site was not recovered, indicating that groundwater follows different flow paths dependent on water table level.
