[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 1,430 sediment and 567 water samples were collected in the Idaho Falls quadrangle in July and August, 1980 as part of the Savannah River Laboratory (SRL) Idaho Falls Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. The water samples were analyzed by SRL for uranium and 9 other elements and then sent on to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for "supplemental analyses" (31 elements in waters). SRL apparently did not analyze the sediment samples and subsequently did not release an individual quadrangle report for Idaho Falls.
A total of 1,416 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-62(82)). The site coding information for Idaho Falls 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 553 of the SRL water samples from Idaho Falls quadrangle in the GJBX-173(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 Idaho Falls water samples, but contains only site information for the Idaho Falls sediment samples. 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 512 of the Idaho Falls quadrangle ground water samples.
The following is a general listing of all sample types collected and reported for NURE studies in the Idaho Falls 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.
| Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
|---|---|---|---|
| Wet Streams | 4 | Streams | 3 |
| Dry Streams | 15 | Wells | 452 |
| Soils | 1,393 | Springs | 112 |
| Talus | 14 | ||
| Other (may include mine tailings) | 4 | ||
| Total Sediments | 1,430 | Total Waters | 567 |
These Idaho Falls 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 records from all of the above reports. The site information for every record in the GJBX-62(82) and GJBX-173(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 2 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.
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).
Idaho Falls Quadrangle Sediment Data - 1,428 records
Idaho Falls Quadrangle Water Data - 1,119 records
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.
None found.
