National Water-Well Database (NWWDB), Harmonized and Quality-Assured State Water-Well Records for Louisiana
This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Louisiana, reformatted according to a U.S. Geological Survey (USGS) profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). The water-well records are sourced from the state-managed database of the Louisiana Department of Natural Resources and consist primarily of information submitted by licensed well drillers at the time of well completion. These records include well locations, construction details, lithologic logs, static water-level measurements, and pumping test results. To enhance data quality and interpretive value, the USGS performed additional processing to (1) quality assure the records based on a series of data integrity rules and (2) parse and translate raw lithologic descriptions to standardized lithology codes.
