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 864 stream-sediment, 884 surface-water, and 1,205 ground-water samples were collected within the Charleston 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 837 sediment and 2,087 water samples from the Charleston 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)].
Ohio
Subcontractors for the Savannah River Laboratory (SRL) collected at least 1,214 stream-sediment, 1,205 surface-water, and 2,049 ground-water samples within 20 counties from east central Ohio as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. Field sampling was conducted during July - August, 1978. Sample coverage included portions of the Canton, Charleston, Clarksburg, Cleveland, Columbus, and Marion 1:250,000-scale quadrangles. (A total of 7 stream-sediment, 6 surface-water, and 10 ground-water samples were collected within the Charleston 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 330 sediments and 3,252 waters from Ohio; this includes all 7 sediment and all 16 water samples from the Charleston quadrangle. The analytical and site location data for all Ohio samples were released in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)].
SRL: Charleston Quadrangle
SRL did not release a separate report for the Charleston 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
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 Charleston quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 844 | 2,103 |
None | 27 | 2 |
Total Samples | 871 | 2,105 |
Total Data Records | 871 | 2,105 |
The following is a list of all sample types collected and reported for NURE studies in the Charleston quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 871 | Streams | 890 |
Wells | 1,001 | ||
Springs | 214 | ||
Total Sediments | 871 | Total Waters | 2,105 |
These Charleston quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Charleston quadrangle sediment data consist of reformatted records from the Ohio portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)] along with reformatted records from the West Virginia portion 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 Charleston quadrangle sediment data:
Water Records
The Charleston quadrangle water data consist of reformatted records from the Ohio portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)] along with reformatted records from the West Virginia portion of the Delaware, Maryland, Virginia, and West Virginia Data Report [GJBX-103(82)]. The following problems were found and addressed during the reformatting process of the Clarksburg 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).
Charleston Quadrangle Sediment Data - 870 records
Charleston Quadrangle Water Data - 2,098 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 Charleston quadrangle is complete and includes samples from Meigs County in Ohio; and Barbour, Boone, Braxton, Calhoun, Clay, Fayette, Gilmer, Greenbriar, Jackson, Kanawha, Lewis, Lincoln, Logan, Mason, Nicholas, Pocahontas, Putnam, Randolph, Roane, Upshur, Webster, and Wirt 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.
Twenty-seven sediment samples and two water samples within the Charleston 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 |
---|---|---|---|---|
West Virginia | Calhoun | Sediment | 1 | 39 |
West Virginia | Clay | Sediment | 2 | 46 |
West Virginia | Clay | Water | 2 | 105 |
West Virginia | Kanawha | Sediment | 9 | 96 |
West Virginia | Pocahantas | Sediment | 3 | 43 |
West Virginia | Roane | Sediment | 3 | 60 |
West Virginia | Webster | Sediment | 9 | 46 |
None found.
