Geology and Ground Water Info Pages By Nancy Rader, MnGeo
Two new related topics, geology and ground water, have joined MnGeo’s series of first-stop information webpages. These pages provide an overview of Minnesota GIS data, maps and related information available by theme.
The Minnesota Geological Survey (MGS), the Minnesota Department of Natural Resources (DNR), and the U.S. Geological Survey (USGS) offer a wealth of geologic data for the state. The county geologic atlas and regional hydrogeologic atlas programs provide detailed maps and GIS data for many counties; other regional topics include aggregate resources, karst and peat.
Statewide information includes a State Map series, industrial mining, and aeromagnetic maps and data. National and international sources include the National Atlas and the National Geologic Map Database; educational information covers sources such as the Minnesota At-a-Glance series, Geology of Minnesota: A Guide for Teachers, and geologic mapping standards.
Many of the geology sources also include information about Minnesota’s ground water. The first-stop website describes GIS data, web applications, scientific reports, and general information. Web applications integrate a number of data sources about wells, drinking water protection, contamination susceptibility, and water appropriation permits. Some sources are statewide, some nationwide, and some are focused on regions such as the Twin Cities. The Minnesota Department of Health, DNR, MGS, Minnesota Pollution Control Agency, and USGS are the primary providers of this information.
