Version 1.40 (2006)

Brief History and Description of Data

[See History of NURE HSSR Program for a summary of the entire program.]

Illinois
Subcontractors for the Savannah River Laboratory (SRL) collected at least 716 stream-sediment, 337 surface-water, and 1,046 ground-water samples within 16 counties from southern Illinois as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The samples were collected during November - December, 1978 and included portions of the Paducah, Saint Louis, Belleville, and Vincennes 1:250,000-scale quadrangles. (A total of 198 stream-sediment, 75 surface-water, and 277 ground-water samples were collected within the Belleville 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 all 716 sediments and 1,288 waters from Illinois; this includes all 198 sediment and 252 water samples from the Belleville quadrangle. The analytical and site location data for all Illinois samples were released in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)].

Indiana
Subcontractors for the Savannah River Laboratory (SRL) collected at least 126 stream-sediment, 111 surface-water, and 443 ground-water samples within 6 counties from the southern border of Indiana as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediments samples were collected during November 1978 and December 1979 and water samples were collected during November - December, 1978 and February - March, 1979. Sample coverage included portions of the Evansville, Louisville, Paducah, and Vincennes 1:250,000-scale quadrangles. (No Indiana samples were collected within the Belleville 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 78 sediments and 554 waters from Indiana. The analytical and site location data for all Indiana samples were released in the Illinois, Indiana, Kentucky, Tennessee, and Ohio Data Report [GJBX-105(82)].

SRL: Belleville Quadrangle
SRL did not release a separate report for the Belleville 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

Discussion of the Reformatting Process for Belleville Quadrangle

Sediment Records
The Belleville quadrangle sediment data consist of reformatted records from the Illinois 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 Belleville 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 sediment data file.
  2. 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 Franklin and Perry Counties, Illinois 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.
  3. 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 Belleville quadrangle water data consist of reformatted records from the Illinois portion of the Illinois, Indiana, Kentucky, Tennessee, and Ohio GJBX-105(82) Data Report. The following problems were found and addressed during the reformatting process of the Belleville 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. 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 Perry and White Counties, Illinois 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.

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 Belleville quadrangle is limited to the Franklin, Hamilton, Perry, Randolph, and White Counties, Illinois. These counties are found only on the southern border of the Belleville quadrangle. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages.

Eighty water samples within the Belleville quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.

General locations of unanalyzed samples.
State County Sample Media Unanalyzed Samples Total Samples
Illinois Hamilton Stream Water 23 23
Illinois Perry Ground Water 57 73
