Kentucky
Subcontractors for the Savannah River Laboratory (SRL) collected at least 4,901 stream-sediment, 3,966 surface-water, and 6,408 ground-water samples within 90 counties from the state of Kentucky as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during May - November, 1978; August 1979 - January 1980; and April 1980 and water samples were collected during May - June, 1978; September 1978 - March 1979; August - November 1979; and May - June 1980. Sample coverage included portions of the Corbin, Dyersburg, Evansville, Huntington, Jenkins, Johnson City, Louisville, Nashville, Paducah, Vincennes, and Winchester 1:250,000-scale quadrangles. (A total of 334 stream-sediment, 252 surface-water, and 514 ground-water samples were collected within the Corbin 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 982 sediments and 10,365 waters from Kentucky; this includes 49 sediment and 765 water samples from the Corbin quadrangle. The analytical and site location data for all Kentucky samples were released in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(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 530 stream-sediment, 447 surface-water, and 733 ground-water samples were collected within the Corbin 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 392 of the sediment and 1,178 water samples from the Corbin 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 includes Supplemental Analyses records for 53 of the sediment samples from Tennessee within the Corbin quadrangle.
SRL: Corbin Quadrangle
SRL did not release a separate report for the Corbin quadrangle.
ORGDP: Corbin, Johnson City, and Nashville Quadrangles
SRL sent several Tennessee and Kentucky sediment samples to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis of uranium and 31 additional elements. ORGDP released the analytical data for 435 samples in the Corbin, Johnson City, and Nashville Quadrangles GJBX-75(82) Data Report. This report includes data for 389 sediment samples from the Corbin 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 Corbin quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 388 | 1,943 |
Only ORGDP | 389 | 0 |
Only Supplemental Lab | 0 | 0 |
Both SRL and ORGDP | 0 | 0 |
Both SRL and Supplemental Labs | 53 | 0 |
None | 34 | 3 |
Total Samples | 864 | 1,946 |
Total Data Records | 864 | 1,946 |
The following is a list of all sample types collected and reported for NURE studies in the Corbin quadrangle.

These Corbin quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Corbin quadrangle sediment data consist of records from the Kentucky and Tennessee portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio [GJBX-105(82)] Data Report combined with records from the ORGDP Corbin, Johnson City, and Nashville Quadrangles GJBX-75(82) Data Report. 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 Corbin Quadrangle sediment data:
Water Records
The Corbin quadrangle water data consist of reformatted records from the Kentucky and Tennessee portions 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 Corbin 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).
Corbin Quadrangle Sediment Data - 860 records
Corbin Quadrangle Water Data - 1,943 records
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 Corbin quadrangle is complete and includes samples from Adair, Allen, Barren, Clinton, Cumberland, Knox, Laurel, McCreary, Metcalfe, Monroe, Pulaski, Russell, Wayne, and Whitley Counties in Kentucky; and Anderson, Campbell, Cumberland, Clay, De Kalb, Fentress, Jackson, Knox, Macon, Morgan, Overton, Pickett, Putnam, Roane, Scott, Smith, and White Counties in Tennessee. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages.
Three water and thirty-four sediment samples within the Corbin quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.
State | County | Sample Media | Unanalyzed Samples | Total Samples |
---|---|---|---|---|
Kentucky | Knox | Water | 1 | 12 |
Kentucky | McCreary | Sediment | 7 | 54 |
Tennessee | Cumberland | Sediment | 23 | 33 |
Tennessee | Clay | Sediment | 1 | 29 |
Tennessee | Macon | Sediment | 1 | 23 |
Tennessee | Morgan | Water | 1 | 128 |
Tennessee | Pickett | Sediment | 2 | 22 |
Tennessee | Pickett | Water | 1 | 54 |
None found.
