Brief History and Description of Data

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

Totals of 1,418 sediment and 593 water samples were collected in the Boise quadrangle between April and July, 1980 as part of the Savannah River Laboratory (SRL) Boise Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. The water samples and 14 sediment samples were analyzed by SRL for uranium and other elements (16 additional elements in sediments and 9 in waters). The water samples were then sent on to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for "supplemental analyses" (31 elements in waters). SRL apparently did not analyze the remainder of the sediment samples and subsequently did not release an individual quadrangle report for Boise.

A total of 1,337 sediment samples from SRL were sent to ORGDP and analyzed for uranium and up to 31 additional elements. These data were released on microfiche by Oak Ridge as an abbreviated quadrangle report (GJBX-60(82)). The site coding information for Boise quadrangle was summarized with several other western quadrangles in the Oak Ridge GJBX-51(82) report.

In 1982, ORGDP released the data from supplementary analyses for 590 of the SRL water samples from Boise quadrangle in the GJBX-171(82) abbreviated report (on microfiche only). The site coding information for this data set was summarized in the GJBX-164(82) report.

In 1982, SRL released a summary report and data files for 50 quadrangles in the Western United States. This report, GJBX-132(82), contains the analytical data from the Boise samples analyzed by SRL, but contains only site information for the Boise sediment samples that SRL did not analyze. The introduction section of the GJBX-132(82) summary report states:

"The data in the present report may not be identical to those reported previously. This is due to the use of different "scrub" procedures for the preparation of the data for release. The differences should be minor."

SRL analyses of light hydrocarbons (methane, ethane, propane, and butane) in ground waters were released in the GJBX-131(82) summary report for 44 western quadrangles and 3 eastern quadrangles within the United States. This report includes data for 569 of the Boise quadrangle ground water samples.

Data for gold analyses of sediments by SRL neutron activation were released in the GJBX-135(82) summary report. The introduction of that report states:

"This report contains previously unreported neutron-activation analyses of gold in sediment samples determined at SRL. These data were not included in the standard SRL NURE data reports because the gold spectrum was not measured in the original analytical procedure and the report format was designed without the gold analyses being included. Gold analyses became available as the analytical procedure was refined, but the report format was not modified to incorporate these data."

Only those sediment samples that had detectable concentrations of gold by neutron activation analysis were given in the GJBX-135(82) report. Sediment samples with concentrations below detection limits were not reported and can only be ascertained by identifying which samples were actually analyzed by neutron activation at SRL.

The following is a general listing of all sample types collected and reported for NURE studies in the Boise quadrangle. The actual number of records in the NEW-FORMAT NURE data files may be greater because of the multiple records needed to preserve all the data.

Summary of Boise quadrangle sample types.
Sediment Sample Type Number of Samples Water Sample Type Number of Samples
Wet Streams 2 Streams 2
Dry Streams 26 Wells 420
Soils 1,333 Springs 171

Volcanic Neck 1
Other (may include mine tailings) 3
Total Sediments 1,418 Total Waters 593

These Boise 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 all of the above reports. The site information for every record in the GJBX-60(82) and GJBX-171(82) quadrangle reports was checked against the "equivalent" record in the GJBX-132(82) western U.S. summary report and any major differences were noted in the REFORMAT comment field.

In the water data file the SRL analyses and supplemental analyses could NOT be combined because of overlapping determinations for 5 elements. Therefore each sample that was analyzed by both labs has two separate records - one for the SRL analysis and one for the ORGDP analysis.

Hydrocarbon data from the GJBX-131(82) report were added to fields in the appropriate ground water records and this addition was noted for each record in the REFORMAT comment field.

Gold concentrations from the GJBX-135(82) report were added to the appropriate sediment records. A value of -0.01 (<0.01 ppm Au) was added to all other sediment samples determined to have been analyzed by SRL neutron activation. This value was chosen because 0.01 is the lowest reported gold concentration in the entire report.



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).

Boise Quadrangle Sediment Data - 1,418 records
Boise Quadrangle Water Data - 1,183 records



Notes for Data Users

Many records contain analytical values with insignificant digits. Most data should only have 2 or 3 significant digits. Differences after the second or third digit should be ignored.



Other NURE Geochemical Data for the Boise Quadrangle

None found.
