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 76 stream-sediment, 74 surface-water, and 141 ground-water samples were collected within the Marion 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 31 sediment and 215 water samples from the Marion 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: Marion Quadrangle
SRL did not release a separate report for the Marion quadrangle.
ORGDP: Canton, Cleveland, Marion, Pittsburgh, and Warren Quadrangles
SRL sent 464 Ohio and 161 Pennsylvania sediment samples to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis of uranium and 31 additional elements. ORGDP released the analytical data for 625 samples in the Canton, Cleveland, Marion, Pittsburgh, and Warren Quadrangles GJBX-80(82) Data Report (A total of 53 samples were from the Marion 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 Marion quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 17 | 215 |
Only ORGDP Lab | 39 | 0 |
Both SRL and ORGDP Labs | 14 | 0 |
None | 6 | 0 |
Total Samples | 76 | 215 |
Total Data Records | 90 | 215 |
The following is a list of all sample types collected and reported for NURE studies in the Marion quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 76 | Streams | 74 |
Wells | 117 | ||
Springs | 24 | ||
Total Sediments | 76 | Total Waters | 215 |
These Marion quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Marion quadrangle sediment data consist of reformatted records from the Ohio portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)]. These records were compared and combined with Canton quadrangle records from the ORGDP Canton, Cleveland, Marion, Pittsburgh, and Warren Quadrangles GJBX-80(82) Data Report. Site descriptive information and coordinates were compared for all corresponding records. The following problems were found and addressed during the reformatting process of the Marion quadrangle sediment data:
Water Records
The Marion quadrangle water data consist of reformatted records from the the Ohio portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)]. The following problems were found and addressed during the reformatting process of the Marion 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).
Marion Quadrangle Sediment Data - 90 records
Marion Quadrangle Water Data - 215 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 Marion quadrangle limited to four counties along the eastern border of the quadrangle and includes samples from Coshocton, Holmes, Muskingum, and Wayne Counties in Ohio. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverage.
Six stream-sediment samples within the Marion quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.
State | County | Unanalyzed Samples | Total Samples |
---|---|---|---|
Ohio | Coshocton | 5 | 24 |
Ohio | Wayne | 1 | 34 |
None found.
