National Water-Well Database (NWWDB), State Water-Well Records for Michigan
This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Michigan, 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 Michigan Department of Environment, Great Lakes, and Energy 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. No additional processing or interpretation has been performed by the USGS beyond formatting to align with the GWML2 standard and applying a baseline set of data integrity rules. The data are provided largely "as-is."
