From abstract: This abbreviated data report presents results of ground water, surface water, and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Bluefield 1* x 2 quadrangle. Surface sediment samples were collected at 886 sites, and surface water samples were collected at 595 of these sites. Ground water samples were collected at 1374 of these sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, for uranium and 8 other elements in ground water, and for uranium and 9 other elements in surface water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.
