Summary

Since the 1940's, commercial, academic and government hydrologists have used aquifer tests to estimate the hydrogeologic properties of an aquifer near test wells. Results from these tests are recorded in various files, databases, reports, and scientific publications. The U.S. Geological Survey (USGS), Lower Mississippi-Gulf Water Science Center (LMG) is aggregating all aquifer test results from Alabama, Arkansas, Louisiana, Mississippi, and Tennessee into a single dataset that is publicly available in a machine-readable format. The LMG-Hydrogeologic Aquifer Test Dataset – December 2021 contains information and results from 690 hydrogeologic aquifer tests. Additionally, this dataset contains 7 attribute tables (.txt files) with information [...]

Summary

Since the 1940's, commercial, academic and government hydrologists have used aquifer tests to estimate the hydrogeologic properties of an aquifer near test wells. Results from these tests are recorded in various files, databases, reports, and scientific publications. The U.S. Geological Survey (USGS), Lower Mississippi-Gulf Water Science Center (LMG) is aggregating all aquifer test results from Alabama, Arkansas, Louisiana, Mississippi, and Tennessee into a single dataset that is publicly available in a machine-readable format.

The LMG-Hydrogeologic Aquifer Test Dataset – December 2021 contains information and results from 690 hydrogeologic aquifer tests. Additionally, this dataset contains 7 attribute tables (.txt files) with information for various fields, a zip file containing the geospatial data, a companion attribute table as a .txt file and a readme text file with definitions and descriptions of the attributes and attribute tables.

The LMG-Hydrogeologic Aquifer Test dataset – Dec2021 is available in two formats:
1) a tab delimited text (.txt) UTF-8 file and
2) an ESRI GIS point shapefile.

LMG_HydrogeologicTestDataset_Dec2021.zip: Esri vector data storage format (shapefile) files for geographic information system software with well locations attributed with location data, well construction data, aquifer data, groundwater test data, hydrogeologic data, and ancillary data.

NOTE ON DATA SOURCES:
Non-USGS hydrogeologic test results reported in this data set have not been through the USGS review and approval process. Only hydrogeologic test results from USGS publications should be considered to have USGS Director’s approval. All other test results should be considered provisional. Provisional data are released on the condition that neither the USGS nor the United States Government may be held liable for any damages resulting from its use.

NOTE:
If you have aquifer test data estimating the hydrogeologic properties of an aquifer, you would like added to this dataset or have found an error, please contact the USGS so we may incorporate the information into the next version of the LMG hydrogeologic test dataset.

This dataset was developed as part of the U.S. Geological Survey, Mississippi Alluvial Plain Regional Water-Availability Study.
