National Water-Well Database (NWWDB): Derived Aquifer Properties and Harmonized Lithologic Logs for the Conterminous United States
The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies by licensed drillers constitute a large source of hydrogeologic information, including the locations and distribution of water wells, construction materials and completion depths, lithologic logs, groundwater levels, and the results of pumping or aquifer tests. Standardization was performed based on a U.S. Geological Survey (USGS) profile of the Open Geospatial Consortium (OGC) GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html)....
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
