Brief History and Description of Data

[See History of NURE HSSR Program for a summary of the entire program.]

In 1976, three private subcontractors, under contract with the Los Alamos Scientific Laboratory (LASL), collected water and stream sediments samples from the New Mexico portions of the Douglas, Silver City, Clifton, and St. Johns quadrangles. All of the samples were sent to LASL for uranium analyses and the data for all 4 quadrangles were released in the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) GJBX-69(78) report. Of those reported, 237 sediment and 181 water samples were collected within the Douglas quadrangle.

In 1977, the entire NURE HSSR program changed from a study area basis (State, County, or geomorphic provinces) to a 1° x 2° quadrangle basis. As a result of this decision, the responsibility for the Arizona portion of the Douglas quadrangle was reassigned to the LASL. According to the last LASL NURE progress report [GJBX-5(80)], this area was scheduled to be sampled during 1980. Apparently though, no samples for this Arizona area were subsequently collected or analyzed by LASL before the NURE program ended.

Out of the samples collected in 1976, LASL sent 235 sediment and 161 water samples from the New Mexico portion of the Douglas quadrangle to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for multielement analyses. These data were released by ORGDP as the Douglas Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study GJBX-244(81) report.

The following is a list of NURE sample types collected for all studies within the Douglas quadrangle study.

Summary of Douglas quadrangle sample types.
Sediment Sample Type Number of Samples Water Sample Type Number of Samples
Wet Streams 7 Streams 7
Dry Streams 170 Wells 124
Wet Springs 6 Springs 7
Wet Artificial Ponds 33 Artificial Ponds 43
Dry Artificial Ponds 21
Total Sediments 237 Total Waters 181

These Douglas quadrangle samples were analyzed by one or more of the following methods:

Water Samples

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of records from the early New Mexico GJBX-69(78) report combined with records from the ORGDP multielement GJBX-244(81) report. Each sample is represented by a single composite record. Any problems found during the reformatting process are noted in the REFORMAT comment field.

Download The Data

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).

Other NURE Geochemical Data for the Douglas Quadrangle

A summary evaluation report was prepared for the Douglas quadrangle by The Bendix Field Engineering Corporation of Grand Junction, Colorado [PGJ/F-118(82)]. As part of the evaluation process, an additional 262 rock samples were collected from selected parts of the quadrangle. The samples were analyzed for eU and eTh (gamma ray spectroscopy), and selected rock samples were analyzed for U (fluorometric analysis), major element oxides (flame atomic absorption), and trace elements (flame atomic absorption and emission spectrometry. These data were released as microfiche appendices accompanying the summary report.
