[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 1,249 sediment and 1,227 water samples were collected from 1,249 locations in the Survey Pass quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Survey Pass Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected during July of 1978. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements, but LASL was unable to complete the Survey Pass quadrangle data release report. The data were sent to and released by the Bendix Field Engineering Corporation in Grand Junction, Colorado only as a microfiche GJBX-255(81) report. This report does not give any details on the sample collection or analytical methods used for these samples.
LASL sent the 1,227 water samples from the Survey Pass quadrangle to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis. These samples were analyzed for uranium and up to 27 additional elements and the results were released by ORGDP in the GJBX-150(81) report.
The following is a list of NURE sample types collected for these studies in the Survey Pass quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 1,245 | Streams | 1,227 |
Dry Streams | 4 | ||
Total Sediments | 1,249 | Total Waters | 1,227 |
These Survey Pass quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
The data in the NEW-FORMAT NURE data files consist of 1,249 reformatted sediment records from the GJBX-255(81) report and 1,227 reformatted water records from the GJBX-150(81) report. Any changes in the data or problems found are noted in the REFORMAT comment field.
The NURE HSSR data are now available online in two databases: The sediment database (also includes data for soils and some rocks) at http://tin.er.usgs.gov/nure/sediment/ and the water database at http://tin.er.usgs.gov/nure/water/. From these two websites, NURE HSSR data can be selected, examined, summarized, and downloaded by political boundaries (State and County), by quadrangle (1:250,000-scale, 1:100,000-scale, and 1:63,360-scale for Alaska or 1:24,000-scale for the Lower 48 States), and by hydrologic unit (drainage region, subregion, river basin, or sub-basin). Selected data can be downloaded as a dBase file, a shapefile, an HTML table, or ASCII text (tab- or comma-delimited).
Survey Pass Quadrangle Sediment Data - 1,248 records
Survey Pass Quadrangle Water Data - 1,226 records
Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.
The ORGDP fluorometric procedure for uranium required each water sample to be centrifuged before taking an aliquot for analysis. It is not clear whether water samples analyzed by emission spectrometry were also centrifuged prior to analysis.
Values of 99999 are as reported in the GJBX publications and may reflect values above determination limits.
LASL compiled all of the regional HSSR data from Alaskan NURE studies and produced a report [GJBX-32(83] that graphically displays the distribution of selected elements for most of the State. No additional geochemical data were released with this report.
