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. (No samples were collected within the Arkansas portion of the Blytheville 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 6,831 Arkansas water samples. 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)].

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. (A total of 115 stream-sediment, 44 surface-water, and 169 ground-water samples were collected within the Blytheville 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; this includes all 115 sediment and 212 water samples from the Blytheville quadrangle. 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)].

SRL sent 248 sediment samples from Tennessee to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 247 of these samples in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)]. The digital data file accompanying this report does not include Supplemental Analyses for any Tennessee sediment samples within the Blytheville quadrangle.

Alabama
Subcontractors for the Savannah River Laboratory (SRL) collected at least 4,499 stream-sediment, 1,486 surface-water, and 6,204 ground-water samples within 53 counties from the northern two-thirds of Alabama as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during June - December, 1976 and March 1978 - January 1979, and water samples were collected during January - September, 1977 and December 1977 - March 1979 and included portions of the Andalusia, Atlanta, Birmingham, Blytheville, Dothan, Gadsden, Hattiesburg, Meridian, Montgomery, Phenix City, Rome, Tupelo, and West Point 1:250,000-scale quadrangles. (Only 1 ground-water sample was collected within the Blytheville 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 4,489 sediments and 7,677 waters from Alabama; this includes the 1 water sample from the Blytheville quadrangle. The analytical and site location data for all Alabama samples were released in the Alabama and Georgia Data Report [GJBX-403(81)].

SRL sent 1,476 sediment samples from Alabama to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 1,471 of these samples in the Alabama and Georgia Data Report [GJBX-403(81)]. The digital data file accompanying this report does not include Supplemental Analyses for any Alabama sediment samples within the Blytheville quadrangle.

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 Blytheville 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: Blytheville Quadrangle
SRL did not release a separate report for the Blytheville 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 Blytheville quadrangle.

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

Sediment Samples

• SR1: Savannah River Neutron Activation Analysis - Neutron Counting of sediments for U.
• SR2: Savannah River Neutron Activation Analysis of sediments for Al, Ce, Dy, Eu, Fe, Hf, La, Lu, Mn, Na, Sc, Sm, Th, Ti, V, and Yb. (Note: Au values were reported later for this method.)

Water Samples

• SR4: Savannah River Neutron Activation Analysis - Neutron Counting of waters for U.
• SR5: Savannah River Neutron Activation Analysis of waters for Al, Br, Cl, Dy, F, Mn, Na, and V. (Note: Mg may also be reported by this method.)

Discussion of the Reformatting Process for Blytheville Quadrangle

Sediment Records
The Blytheville quadrangle sediment data consist of reformatted records from the Tennessee portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio [GJBX-105(82)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Blytheville Quadrangle sediment data:

1. During reformatting, contamination codes for "residential" and "recreation" were found to be missing from each State's CONTAMC field. The presence of one of these two codes was indicated only by a "." (period). The missing codes were assigned a value of "unknown" in the CONTAMC field within the final water data file.
2. 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.

Water Records
The Blytheville quadrangle water data consist of reformatted records from the Tennessee portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio [GJBX-105(82)] Data Report plus 1 reformatted record from the Alabama portion of the Alabama and Georgia [GJBX-403(81)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Blytheville quadrangle water data:

1. The original NURE format for surface-water files did not include much information about the character of the sample location. This missing information includes observations taken at each site on the stream width, depth, and flow, water color, surrounding vegetation, local relief, weather, and possible contaminants. This information is given in records for stream-sediment samples that were collected at the same locations. The available site descriptive information for stream-water sites were compared with the corresponding stream-sediment site records. The missing site descriptive data were then added to stream-water records from the corresponding stream-sediment sample records. Sources of data and any problems found are described 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 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).

Notes for Data Users

In the eastern United States, SRL collected samples primarily by county. Often, not all counties within a quadrangle were completely sampled. Sample coverage in the Blytheville quadrangle is limited to the Benton, Carroll, Dyer, and Gibson Counties in Tennessee and Lauderdale County, Alabama. These counties are found on the northern border and southeastern corner of the Blytheville quadrangle. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages.

One well water sample collected in Carroll County, Tennessee within the Columbia quadrangle was not analyzed by any of the various laboratories.

Other NURE Geochemical Data for the Blytheville Quadrangle

None found.
