Several waste disposal sites are located on or adjacent to the karstic Maynardville Limestone (Cmn) and the Copper Ridge Dolomite (Ccr) at the Department of Energy Y-12 Plant. These formations receive contaminants from nearby disposal sites, and transport of these contaminants through the formations can be quite rapid due to the karst flow system. Groups of wells, aligned perpendicular to strike, were drilled to investigate the characteristics of the Cmn, and these wells are identified as Pickets. In order to evaluate transport processes through the karst aquifer, the formations must be characterized. As one component of this characterization effort, cross borehole tests were conducted where water was injected into one well at a site, and water level responses were monitored in nearby wells to determine the directions in which quick flow is more dominant. The ultimate objective of the studies of the Cmn is to characterize the hydrologic characteristics of the karst aquifer and to identify the generalized configuration of the conduit systems and portions subject to a significant quick flow component (i.e., higher hydraulic conductivity zones). The resultant conceptual model will be useful in constructing numerical models to be used to predict flow paths.
