Savannah River Laboratory hydrogeochemical and stream sediment reconnaissance. Raw data release V; studies in the Spruce Pine, Moore, and Johnston, North Carolina, areas. National Uranium Resource Evaluation Program

Orientation studies were conducted in the Spruce Pine, Moore, and Johnston, North Carolina, areas in preparation for a hydrogeochemical and stream sediment reconnaissance. The studies were conducted by the Savannah River Laboratory as part of the National Uranium Resource Evaluation (NURE) Program. A total of 298 surface sites and 210 ground water sites were sampled over 1800 square-miles. Uranium concentrations in sediment ranged from 0.6 to 39.4 parts per million (ppM) in Spruce Pine, from 1.8 to 526.1 ppM in Moore, and from 1.4 to 69.1 ppM in Johnston. Uranium concentrations in water ranged from less than 5 to 6780 parts per trillion (pptr) in Spruce Pine, from less than 5 to 16,300 pptr in Moore, and from less than 5 to 1210 pptr in Johnston. Plots are presented to show statistical and areal distribution of uranium concentrations in ground water, stream water, and stream sediment. Tabular data for each site include temperature; alkalinity, conductivity; pH; dissolved oxygen; Eh; sulfate, nitrate, and phosphate ions; ammonia; and neutron activation analyses for up to 20 supplementary elements in sediment and water
