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, Vincennes, and Winchester 1:250,000-scale quadrangles. (A total of 1,192 stream-sediment, 1,158 surface-water, and 1,310 ground-water samples were collected within the Jenkins 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 142 sediment and 2,461 water samples from the Jenkins 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)].

Virginia
Subcontractors for the Savannah River Laboratory (SRL) collected at least 5,667 stream-sediment, 2,598 surface-water, and 4,834 ground-water samples within 96 counties from Virginia as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during July - October 1976; August - September 1977; and April - November 1978, and water samples were collected during December 1976 - September 1977; April - October 1978; and June - August 1979. Sample coverage included portions of the Baltimore, Bluefield, Charlottesville, Chincoteague, Cumberland, Currituck Sound, Greensboro, Jenkins, Johnson City, Norfolk, Richmond, Roanoke, Salisbury, Washington, and Winston-Salem 1:250,000-scale quadrangles. (A total of 88 stream-sediment, 85 surface-water, and 145 ground-water samples were collected within the Jenkins 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 5,522 sediments and 7,416 waters from Virginia; this includes 84 sediment and 230 water samples from the Jenkins quadrangle. The analytical and site location data for all Virginia samples were released in the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)].

SRL sent 2,719 sediment samples from Virginia to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 2,711 of these samples in the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)]. The digital data file accompanying this report includes Supplemental Analyses for 2 Virginia sediment samples within the Jenkins quadrangle.

West Virginia
Subcontractors for the Savannah River Laboratory (SRL) collected at least 2,965 stream-sediment, 2,910 surface-water, and 4,060 ground-water samples within 55 counties from West Virginia as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during May - November 1978 and August - September 1979; water samples were collected during April - August 1977; May - September 1978; and July 1980. Sample coverage included portions of the Baltimore, Bluefield, Canton, Charleston, Charlottesville, Clarksburg, Columbus, Cumberland, Huntington, and Jenkins 1:250,000-scale quadrangles. (A total of 82 stream-sediment, 78 surface-water, and 112 ground-water samples were collected within the Jenkins 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 2,919 sediments and 6,965 waters from West Virginia; this includes all 82 sediment and all 190 water samples from the Jenkins quadrangle. The analytical and site location data for all West Virginia samples were released in the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)].

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

ORGDP: Jenkins Quadrangle
SRL sent several 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 1,007 samples in the Jenkins Quadrangle GJBX-78(82) Data Report. 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 Jenkins quadrangle samples.

The following is a list of all sample types collected and reported for NURE studies in the Jenkins quadrangle.

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

Discussion of the Reformatting Process for Jenkins Quadrangle

Sediment Records
The Jenkins quadrangle sediment data consist of reformatted records from the Kentucky portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)] along with reformatted records from the Virginia and West Virginia portions of the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)]. These records were compared and combined with records from the ORGDP Jenkins Quadrangle GJBX-78(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 Jenkins 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. Unlikely sample collection dates were found for two samples. These dates were removed from the SAMPDAT field. For each record, the original SAMPDAT value and the most likely correct value was added as a comment to the REFORMAT field.
3. The original ORGDP file for the Jenkins quadrangle did not include all of the 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. In addition, the longitude coordinate reported in the ORGDP file only had 3 decimal places instead of the 4 decimal places found in the corresponding records from SRL State files. When combining corresponding SRL and ORGDP records, all of the site descriptive data and the longitude values to 4 decimal places from the SRL data files were preserved in the final database.
4. An analysis of latitude-longitude site coordinates identified several stream-sediment samples that were missing coordinates, did not plot within expected state, county, or map boundaries, or had differing coordinates in corresponding records. To correct or confirm sample coordinates, the original field collection maps for Clay, Estill, Floyd, Laurel, Lawrence, Lee, Leslie, Montgomery, and Pike Counties, Kentucky were obtained and re-digitized. The newly re-digitized coordinates were added to the database and the coordinates from the original file(s) were recorded in the COORDPRB comment field. When the newly re-digitized coordinates were not significantly different, that confirmation of the site location was also noted in the COORDPRB comment field.
5. After re-digitizing, one stream-sediment sample from Clay County, Kentucky originally located in the Jenkins quadrangle now plots in the adjacent Johnson City quadrangle.
6. 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 Jenkins quadrangle water data consist of reformatted records from the the Kentucky portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)] along with reformatted records from the Virginia and West Virginia portions of the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)]. The following problems were found and addressed during the comparison and reformatting stages for the Jenkins 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.
2. 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.
3. Unlikely sample collection dates were found for five samples. These dates were removed from the SAMPDAT field. For each record, the original SAMPDAT value and the most likely correct value was added as a comment to the REFORMAT field.
4. An analysis of latitude-longitude site coordinates identified several stream-water samples that were missing coordinates, did not plot within expected state, county, or map boundaries, or had differing coordinates in corresponding records. To correct or confirm sample coordinates, the original field collection maps for Clay, Estill, Floyd, Laurel, Lawrence, Lee, Leslie, Montgomery, and Pike Counties, Kentucky were obtained and re-digitized. The newly re-digitized coordinates were added to the database and the coordinates from the original file(s) were recorded in the COORDPRB comment field. When the newly re-digitized coordinates were not significantly different, that confirmation of the site location was also noted in the COORDPRB comment field.
5. After re-digitizing, one stream-water sample from Clay County, Kentucky originally located in the Jenkins quadrangle now plots in the adjacent Johnson City quadrangle.
6. An analysis of latitude-longitude site coordinates identified several ground-water samples that were missing coordinates, did not plot within expected state, county, or map boundaries, or had differing coordinates in corresponding records. To correct or confirm sample coordinates, the original field collection maps for Clay, Johnson, Knott, Laurel, Lee, Martin, and Pike Counties, Kentucky were obtained and re-digitized. The newly re-digitized coordinates were added to the database and the coordinates from the original file(s) were recorded in the COORDPRB comment field. When the newly re-digitized coordinates were not significantly different, that confirmation of the site location was also noted in the COORDPRB comment field.
7. One ground-water sample was identified with a SRLID in the 600's. This sample was missing latitude and longitude coordinates. Evidence from original sample site field notes strongly suggests that this is a duplicate sample collected later from a previously sampled 500's series site (i.e. SRLID site number ABCD618R is the same location as ABCD518R). The coordinates from the original 500's series site was added to the matching 600's record and this change was noted in the REFORMAT and COORDPRB comment fields.

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).

Jenkins Quadrangle Water Data - 2,888 records

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 Jenkins quadrangle is complete and includes samples from Breathitt, Clark, Clay, Estill, Floyd, Jackson, Johnson, Knott, Knox, Laurel, Lawrence, Lee, Leslie, Letcher, Magoffin, Martin, Menifee, Montgomery, Morgan, Owsley, Perry, Pike, Powell, and Wolfe Counties in Kentucky; Buchanan, Dickenson, Russell, and Wise Counties in Virginia; and Logan, Mingo, and Wayne Counties in West Virginia. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverage.

Forty-seven stream-sediment samples and 2 well water samples within the Jenkins quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.

Other NURE Geochemical Data for the Jenkins Quadrangle

None found.
