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. (No samples were collected within the Mississippi portion of the West Point 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)].
Alabama
Subcontractors for the Savannah River Laboratory (SRL) collected at least 4,499 stream-sediment, 1,486 surface-water, and 6,204 ground-water samples within 53 counties from the northern two-thirds of Alabama as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during June - December, 1976 and March 1978 - January 1979, and water samples were collected during January - September, 1977 and December 1977 - March 1979. Sample coverage included portions of the Andalusia, Atlanta, Birmingham, Blytheville, Dothan, Gadsden, Hattiesburg, Meridian, Montgomery, Phenix City, Rome, Tupelo, and West Point 1:250,000-scale quadrangles. (A total of 102 stream-sediment, 69 surface-water, and 189 ground-water samples were collected within the West Point 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 4,489 sediments and 7,677 waters from Alabama; this includes all 102 sediment and 257 water samples from the West Point quadrangle. The analytical and site location data for all Alabama samples were released in the Alabama and Georgia Data Report [GJBX-403(81)].
SRL sent 1,476 sediment samples from Alabama to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 1,471 of these samples in the Alabama and Georgia Data Report [GJBX-403(81)]. The digital data file accompanying this report does not include Supplemental Analyses for any Alabama sediment samples within the West Point quadrangle.
SRL: Birmingham and West Point Quadrangles
Occasionally, SRL released abbreviated reports for quadrangles under their responsibility. These reports include neutron activation analyses done at SRL. SRL released an abbreviated report for the Birmingham and West Point quadrangles [GJBX-191(81)]. Data tables with analyses are included within the microfiche accompanying this report. Data found in this report appear to be the same data as that found in the state digital data-file. No separate digital data file accompanies this 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
The following is a list of all sample types collected and reported for NURE studies in the West Point quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 102 | Streams | 69 |
Wells | 154 | ||
Springs | 35 | ||
Total Sediments | 102 | Total Waters | 258 |
These West Point quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The West Point quadrangle sediment data consist of reformatted records from the Alabama portion of the Alabama and Georgia [GJBX-403(81)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the West Point quadrangle sediment data:
Water Records
The West Point quadrangle water data consist of reformatted records from the Alabama portion of the Alabama and Georgia [GJBX-403(81)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the West Point 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).
West Point Quadrangle Sediment Data - 102 records
West Point Quadrangle Water Data - 258 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 West Point quadrangle is limited to the Greene, Lamar, and Pickens Counties, Alabama. These counties are found on the eastern border of the West Point quadrangle. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverages.
One well water sample collected in Pickens County, Alabama within the West Point quadrangle was not analyzed by any of the various laboratories.
None found.
