Abstract: Field and laboratory data are presented for 161 water samples and 235 sediment samples from the Douglas Quadrangle, Arizona; New Mexico. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-69(78). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by Uranium Resource Evaluation Project at Oak Ridge, Tennessee.

Data collected as part of the Douglas Quadrangle in Arizona including laboratory and field data on waters and sediments.

From abstract: This report presents the results of the geochemical reconnaissance sampling in the Prescott quadrangle of the National Topographic Map Series (NTMS). Wet and dry sediment samples were collected throughout the 18,770 square kilometer arid-to-semiarid area and water samples at available streams, springs, and wells.

Supplementary data containing sediment sample analyses to accompany a report on hydrogeochemical and stream sediment reconnaissance for the Presscott NTMS Quadrangle, Arizona.

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Needles 1' x 2 quadrangle. Surface sediment samples were collected at 1672 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 49 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.

Supplementary data containing tabulated elemental concentration data in surface sediment and ground water samples in addition to areal distribution maps, histograms, and cumulative frequency plots. Also included is sample site location data for surface and ground water samples and a user's guide. This data accompanies a report on hydrogeochemical and stream sediment reconnaissance in California and Arizona.

From introduction: This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Shiprock National Topographic Map Series (NTMS) quadrangle, New Mexico/Arizona, by the Los Alamos Scientific Laboratory (LASL).
