Oklahoma
Subcontractors for the Savannah River Laboratory (SRL) collected at least 2,493 stream sediment, 2,751 ground water, and 375 stream water samples within 24 counties of the eastern portion of Oklahoma as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between May and October of 1978 and included portions of the Ardmore, Enid, Fort Smith, McAlester, Oklahoma City, Sherman, Texarkana, and Tulsa 1:250,000-scale quadrangles. (A total of 767 stream sediment, 111 surface-water, and 843 ground-water samples were collected within the Fort Smith quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 879 stream sediment samples and all 3,126 water samples from Oklahoma; this includes 535 stream-sediment and all 954 water samples from the Fort Smith quadrangle. The analytical and site location data for all Oklahoma sediment and water samples were released as separate files in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
Arkansas
Subcontractors for the Savannah River Laboratory (SRL) collected at least 3,292 stream sediment, 5,121 ground water, and 1,711 stream water samples within 43 counties of central Arkansas as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between May and October of 1978 and included portions of the El Dorado, Fort Smith, Greenwood, Harrison, Helena, Little Rock, McAlester, Memphis, Poplar Bluff, Russellville, Texarkana, and Tulsa 1:250,000-scale quadrangles. (A total of 237 stream sediment, 100 surface-water, and 320 ground-water water samples were collected within the Fort Smith quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 2,416 stream sediment samples and 6,831 water samples from Arkansas; this includes all 237 stream-sediment and all 420 water samples from the Fort Smith quadrangle. The analytical and site location data for all Arkansas sediment and water samples were released as a separate file in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
SRL: Fort Smith Quadrangle
SRL did not release a separate report for the Fort Smith quadrangle.
ORGDP: Oklahoma City, Fort Smith, and Russellville Quadrangles
SRL sent several Oklahoma and Arkansas sediment samples to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis of uranium and 31 additional elements. ORGDP released the analytical data for 260 samples in the Oklahoma City, Fort Smith, and Russellville Quadrangles GJBX-71(82) Data Report. This report includes data for 228 sediment samples from the Fort Smith quadrangle. The site coding information for this data set was summarized in the GJBX-51(82) report.
Gold Analyses
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.
Summary Tables
Because of the various laboratories and analytical methods used, some SRL samples may have been analyzed once, twice, or not at all. The following table summarizes the analysis of Fort Smith quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 772 | 1,374 |
Only ORGDP | 230 | 0 |
Both SRL and ORGDP | 0 | 0 |
None | 2 | 0 |
Total Samples | 1,004 | 1,374 |
Total Data Records | 1,004 | 1,374 |
The following is a list of all sample types collected and reported for NURE studies in the Fort Smith quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 1,004 | Streams | 211 |
Wells | 1,138 | ||
Springs | 25 | ||
Total Sediments | 1,004 | Total Waters | 1,374 |
These Fort Smith quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Fort Smith quadrangle sediment data consist of records from the Oklahoma and Arkansas portions of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report combined with records from the ORGDP Oklahoma City, Fort Smith, and Russellville Quadrangles GJBX-71(82) Data Report. When combining sample records, site descriptive information and coordinates were compared for all corresponding records. The following problems were found and addressed during the comparison and reformatting stages for the Fort Smith quadrangle sediment data:
Water Records
The Fort Smith quadrangle water data consist of reformatted records from the Oklahoma and Arkansas portions of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report. The following problems were found and addressed during the reformatting process of the Fort Smith quadrangle water 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 web sites, 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).
Fort Smith Quadrangle Sediment Data - 1,003 records
Fort Smith Quadrangle Water Data - 1,374 records
In the eastern United States, SRL collected samples primarily by county. Often, not all counties within a quadrangle were completely sampled. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages. Samples were collected from all of the Oklahoma and Arkansas counties within the Fort Smith quadrangle. The sampled Arkansas counties include Crawford, Franklin, Logan, Sebastian, Scott, and Washington. The sample Oklahoma counties include Adair, Cherokee, Haskell, Latimer, Le Flore, McIntosh, Muskogee, Okmulgee, Pittsburg, Sequoyah, Tulsa, and Wagoner.
Two stream-sediment samples collected in Pittsburg(1) and Sequoyah(1) Counties, Oklahoma within the Fort Smith quadrangle were not analyzed by any of the various laboratories.
Northern Arkansas Orientation Study
An orientation study of northern Arkansas, including parts of the Ft. Smith, Harrison, Russellville, and Tulsa quadrangles, was conducted by SRL (GJBX-212(82)) in Benton, Carroll, Madison, and Washington counties. Analyses for 335 stream-sediment and 335 water samples are given in tables within the report. The water samples were analyzed by neutron activation analysis for U, Br, Cl, F, Mn, Na, Al, and Dy. In addition, the ground-water samples were analyzed for He. Sediment samples were analyzed by neutron activation analysis for U, Th, Hf, Ce, Fe, Mn, Sc, Ti, V, Al, Dy, Eu, La, Sm, Yb, and Lu.
