San Bernardino 1/sup 0/ x 2/sup 0/ NTMS area, California: data report (abbreviated)

Technical Report ·
OSTI ID:6022867

This abbreviated data report presents results of ground wate and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) San Bernardino 1/sup 0/ x 2/sup 0/ quadrangle. Surface sediment samples were collected at 1539 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Surface water samples were collected at 39 of these sites. Ground water samples were collected at 392 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Key data from stream water sites (also on microfiche in pocket) include (1) water quality measurements (pH, conductivity, and alkalinity) and (2) elemental analyses (U, Al, Br, Cl, Dy, F, Mg, Mn, Na, and V). Uranium concentrations above detection limits in the sediment ranged from 1.0 to 137 ppM, with a mean of 4.2 ppM. Uranium concentrations above detection limits in the ground water samples ranged from 0.03 to 93.9 ppB, with a mean of 7.6 ppB.
