Savannah River Laboratory Hydrogeochemical and Stream Sediment Reconnaissance. Preliminary Basic Data Release, Ground Water in Winston-Salem 1 exp 0 X 2 exp 0 NTMS Area, North Carolina, Virginia, and Tennessee. National Uranium Resource Evaluation Program

摘要

This report presents preliminary results of ground water reconnaissance in the Winston-Salem National Topographic Map Series (NTMS) 1 exp 0 x 2 exp 0 quadrangle. This report is issued as a supplement to SRL Document DPST-77-146-1, GJBX-66(77), which contained a geologic description of the area and analytical results for stream sediment samples. Ground water samples were collected at 784 sites for a nominal density of one site per 25 square kilometers (ten square miles). Neutron activation analysis (NAA) results are given for uranium and 9 other elements. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Statistical summaries of data and a brief description of results are given. Key data are presented in page-sized hard copy. Supplementary data are on microfiche. Key data from ground water sites include (1) water quality measurements (pH, conductivity, and alkalinity) and (2) element analyses (U, Na, Cl, Mg, Al, Mn, Br, V, and F). Supplementary data include site descriptors, information about the collection of the samples (well age, well depth, frequency of use of well, etc.), and analytical data for dysprosium.
