Tennessee
Subcontractors for the Savannah River Laboratory (SRL) collected at least 3,309 stream-sediment, 1,584 surface-water, and 3,574 ground-water samples within 58 counties from the eastern half and the northwestern corner of Tennessee as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The samples were collected during June - December, 1976 and March - November, 1978 and included portions of the Blytheville, Chattanooga, Columbia, Corbin, Dyersburg, Gadsden, Johnson City, Knoxville, Nashville, Rome, and Winston-Salem 1:250,000-scale quadrangles. (None of these water samples were collected within the Tennessee portion of the Memphis quadrangle.) These samples were sent to SRL for analysis of uranium and additional elements (16 in sediments and 9 in waters). SRL was able to analyze 2,450 sediments and 5,149 waters from Tennessee. The analytical and site location data for all Tennessee samples were released in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)].
Arkansas
Subcontractors for the Savannah River Laboratory (SRL) collected at least 3,292 stream-sediment, 5,121 ground-water, and 1,711 surface-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 44 stream-sediment, 38 surface-water, and 76 ground-water samples were collected within the Memphis quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 2,416 Arkansas stream-sediment samples and 6831 Arkansas water samples; this includes all 44 stream-sediment and all 114 water samples from the Memphis quadrangle. The analytical and site location data for all Arkansas sediment and water samples were released as separate files in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
Missouri
Subcontractors for the SRL collected at least 2,162 stream-sediment, 1,340 surface-water, and 3,423 ground-water samples within 30 counties from the southeast and southwest corners of Missouri as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The samples were collected during May - August, 1978, October - December, 1978, and May - June, 1979 and included portions of the Dyersburg, Harrison, Joplin, Paducah, Poplar Bluff, Rolla, St. Louis, Springfield, and Tulsa 1:250,000-scale quadrangles. (No samples were collected within the Missouri portion of the Memphis quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 1,669 Missouri stream-sediment samples and 4,762 Missouri water samples. The analytical and site location data for all Missouri samples were released in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
SRL: Memphis Quadrangle
SRL did not release a separate report for the Memphis quadrangle.
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
The following is a list of all sample types collected and reported for NURE studies in the Memphis quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 44 | Streams | 38 |
Wells | 70 | ||
Springs | 6 | ||
Total Sediments | 44 | Total Waters | 114 |
These Memphis quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Memphis quadrangle sediment data consist of reformatted records from the Arkansas portion of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Memphis quadrangle sediment data:
Water Records
The Memphis quadrangle water data consist of reformatted records from the Arkansas portion of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Memphis 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).
Memphis Quadrangle Sediment Data - 44 records
Memphis Quadrangle Water Data - 114 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 the northern border of the Memphis quadrangle. The sampled Arkansas counties include Greene, Izard, Lawrence, Lonoke, and Sharp. Apparently, no NURE HSSR samples were collected within the Tennessee or Missouri portions of the Memphis quadrangle.
None found.
