Mississippi
Subcontractors for the Savannah River Laboratory (SRL) collected at least 814 ground-water samples within 14 counties of southwest central Mississippi as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between August, 1978 and January, 1979 and included portions of the Hattiesburg, Jackson, Meridian, and Natchez 1:250,000-scale quadrangles. (27 of these water samples were collected within the Jackson quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze all 814 Mississippi water samples. The analytical and site location data for all Mississippi water samples were released as a separate file in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
Louisiana
Subcontractors for the Savannah River Laboratory (SRL) collected at least 1,017 stream-sediment samples within 15 parishes of central Louisiana as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between August and October of 1978 and included portions of the Alexandria, Baton Rouge, Jackson, Lake Charles, Natchez, Palestine, Shreveport, and Tyler 1:250,000-scale quadrangles. (A total of 52 stream-sediment samples were collected within the Jackson quadrangle.) These sediment samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 28 Louisiana stream sediment samples; none of the SRL Louisiana samples from the Jackson quadrangle were analyzed. The analytical and site location data for all Louisiana sediment samples were released as a separate file in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
SRL: Jackson Quadrangle
SRL did not release a separate report for the Jackson quadrangle.
ORGDP: Jackson, Shreveport, and Tyler Quadrangles
SRL sent several Louisiana sediment samples to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis of uranium and 31 additional elements. ORGDP released the analytical data for 209 samples in the Jackson, Shreveport, and Tyler Quadrangles GJBX-68(82) Data Report. This report includes data for 44 sediment samples from the Jackson quadrangle. The site coding information for this data set was summarized in the GJBX-51(82) report.
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 Jackson quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 0 | 27 |
Only ORGDP | 44 | 0 |
Both SRL and ORGDP | 0 | 0 |
None | 8 | 0 |
Total Samples | 52 | 27 |
Total Data Records | 52 | 27 |
The following is a list of all sample types collected and reported for NURE studies in the Jackson quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 52 | Wells | 25 |
Springs | 2 | ||
Total Sediments | 52 | Total Waters | 27 |
These Jackson quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Jackson quadrangle sediment data consist of records from the Louisiana portion of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report combined with records from the ORGDP Jackson, Shreveport, and Tyler Quadrangles GJBX-68(82) Data Report. When combining sample records, 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 Jackson quadrangle sediment data:
Water Records
The Jackson quadrangle water data consist of reformatted records from the Mississippi portion of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Jackson 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).
Jackson Quadrangle Sediment Data - 52 records
Jackson Quadrangle Water Data - 27 records
In the eastern United States, SRL collected samples primarily by county or parish. Often, not all counties or parishes within a quadrangle were completely sampled. Sediment sample coverage in the Jackson quadrangle is limited to the Franklin, Tensas, and Caldwell Parishes in Louisiana. Water sample coverage is limited to Claiborne, Copiah, and Simpson Counties in Mississippi. These Louisiana parishes and Mississippi counties are found only along the southwest and southeast borders of the Jackson quadrangle, respectively. The laboratory and analytical methods used also may vary by county or parish such that adjacent counties or parishes often have very different analytical coverages.
Eight sediment samples within the Jackson quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.
State | County or Parish | Sample Media | Unanalyzed Samples | Total Samples |
---|---|---|---|---|
Louisiana | Franklin | Sediment | 4 | 35 |
Louisiana | Tensas | Sediment | 4 | 14 |
None found.
