Summary

This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Minnesota that have been reformatted based on a USGS profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). Additionally, the water-well records have been quality-assured to remove or nullify parts of water-well records found to be erroneous or logically inconsistent, harmonized via the assignment of common data codes in the lithologic log, and supplemented with estimates of transmissivity from the analysis of specific-capacity data. The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized [...]

Purpose

Uses of the National Water-Well Database (NWWDB) are diverse and may include mapping of the depth to bedrock or potentiometric surface elevation, 3-dimensional stratigraphic modeling, identifying vulnerable aquifers, inferring hydraulic properties of geologic formations, estimating groundwater storage volumes, or performing other analyses for the management of groundwater resources.
