This map shows the locations of sediment sample collection during the Oakes et al 1982 study. Sampling was restricted to water less than 15 feet deep due to equipment limitations therefore samples appear to be pushed towards the shoreline. This map portrays, in relative scale, the depth to highest concentration of Cs-137 in each core. The Cs-137 concentration peak is associated with peak releases from White Oak Lake in the late 50s. Shallow peaks indicate that sediment deposition rates are low or that scouring is occuring.
Deep peaks indicates relatively high deposition rates.
Note the high variability within adjacent cores. This map portrays, in a relative scale, the total Cs-137 at each sample location. This map depicts sampling locations for surface sediment samples collected by Ashwood, et. The purpose of this project was to sample along the exposed shorelines and in the tributaries of Poplar Creek and the Clinch River surrounding K-25 to determine where concentrations of contaminants are highest. This data were incorporated into the GIS and, in conjuction with the Phase 2 sediment data, have been useful in identifying sources of various contaminants.
