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. (A total of 92 stream-sediment, 80 surface-water, and 102 ground-water samples were collected within the Evansville 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; this includes 44 Indiana sediment and all 182 water samples from the Evansville quadrangle. 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)].

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 1,279 stream-sediment, 1,048 surface-water, and 1,397 ground-water samples were collected within the Evansville 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 96 sediment and all 2,445 water samples from the Evansville 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)].

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

ORGDP: Paducah and Evansville Quadrangles
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 1,091 samples in the Paducah and Evansville Quadrangles GJBX-76(82) Data Report. This report includes data for 1,029 sediment samples from the Evansville 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 Evansville quadrangle samples.

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

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

Discussion of the Reformatting Process for Evansville Quadrangle

Sediment Records
The Evansville quadrangle sediment data consist of records from the Indiana and Kentucky portions of the Illinois, Indiana, Kentucky, Tennessee, and Ohio [GJBX-105(82)] Data Report combined with records from the ORGDP Evansville and Paducah Quadrangles GJBX-76(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 Evansville quadrangle sediment data:

1. The SRL and the ORGDP Laboratory each analyzed the same 74 stream-sediment samples from Kentucky. Because of overlapping data fields, it was necessary to create two data records for each sample to preserve all the data.
2. The original ORGDP files for the Paducah and Evansville quadrangles 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. The missing site descriptive data and the complete longitude value were added to ORGDP records from the corresponding SRL State file records. Sources of data and any problems found are described in the REFORMAT comment field.
3. 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.
4. 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.
5. The original latitude-longitude site coordinates for some stream-sediment samples collected within Posey County in Indiana; and within Butler and Ohio Counties in Kentucky plotted outside of the county borders. To determine the correct sample coordinates, the original field collection maps for these counties were obtained and re-digitized. When significantly different, the newly re-digitized coordinates were added to the file and the original State file coordinates 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.
6. 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 Posey County, Indiana; and Butler, Daviess, McLean, and Ohio 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. 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 Evansville quadrangle water data consist of reformatted records from the Indiana and Kentucky portions 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 Evansville 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. Unlikely sample collection dates were found for four 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. 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 Posey County, Indiana; and Butler, Daviess, McLean, and Ohio 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.
4. 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 Christian, Grayson, McLean, and Todd 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.

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 Evansville quadrangle is complete and includes samples from Harrison, Perry, Posey, Spencer, Vanderburgh, and Warrick Counties in Indiana; and Barren, Breckenridge, Butler, Caldwell, Christian, Crittenden, Daviess, Edmonson, Grayson, Hancock, Henderson, Hopkins, Hardin, Hart, Logan, Meade, McLean, Muhlenberg, Ohio, Todd, Union, Warren, and Webster Counties in Kentucky. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages.

Two hundred and seventy-six sediment samples within the Evansville 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 Evansville Quadrangle
