Lineage | Wells selected from the County Well Index (CWI) database managed by the Minnesota Department of Health and the Minnesota Geological Survey that were sampled for chemical analysis. These wells were sampled in the field by Jim Berg or Jeanette Leete (DNR); or Scott Alexander (University of Minnesota). The laboratory analysis of samples was contracted through the Minnesota Department of Health or the Hydrogeochemistry Laboratory in the Department of Geology and Geophysics at the University of Minnesota. The analysis results for the samples were provided to the DNR as electronic spreadsheets. The spreadsheet data were converted to dbf files by Jim Berg and subsequently converted to ArcView shapefiles. These data were combined by Jim Berg with additional chemistry data as shapefiles from the Minnesota Department of Health. The data were transferred to the GIS specialist as an ArcView Shapefile. |
