On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
The project goal is to assist the Minnesota Pollution Control Agency (MPCA) with meeting the objectives of the Surface Water Assessment Grant (SWAG) to conduct field and water chemistry monitoring at MPCA specified lake sampling locations and stream locations. This will be accomplished by collecting water samples at seven lake sites and eight streams in the Kettle and Upper St. Croix Watersheds, as well as compiling and submitting the required data, information and reports.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
This project will provide complementary (same year) physical and chemical data sets for three MPCA prioritized lakes in NE Minnesota to incorporate into the overall State database for MPCA assessment purposes as well as research purposes.
