Description
Summary:Results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Providence 1/sup 0/ x 2/sup 0/ quadrangle are presented. Surface sediment samples were collected at 318 sites. Ground water samples were collected at 180 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 8 other elements in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Data from ground water sites include: water chemistry measurements (pH, conductivity, and alkalinity), physical measurements where applicable (water temperature, well description, etc.), and elemental analyses (U, Al, Br, Cl, Dy, F, Mn, Na, and V). Data from sediment sites include: stream water chemistry measurements (pH, conductivity, and alkalinity), and elemental analyses for sediment samples (U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Sc, Sm, Na, Ti, V, and Yb). Sample site descriptors (stream characteristics, vegetation, etc.) are also tabulated. Areal distribution maps, histograms, and cumulative frequency plots for most elements and for U/Th and U/Hf ratios are included on the microfiche. Key data from stream water sites include: water quality measurements (pH, conductivity, and alkalinity), and elemental analyses (U, Al, Br, Ci, Dy, F, Mg, Mn, Na, and V). Uranium concentrations in the sediments ranged from 1.2 to 61.7 ppM with an average of 4.5 ppM. A group of high uranium concentrations was found in Barnstable County, Massachusetts. These sites also had high concentrations of thorium and rare-earth elements that indicate the presence of a sand with a high proportion of heavy minerals.
