This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
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.
This project will collect real-time parameter data for specific conductance, water temperature, pH, dissolved oxygen, turbidity and stream flow at the United States geological Survey (USGS) gaging stations located at Fargo, ND and Grand Forks, ND on the Red River of the North; and publish the data both on the USGS NWIS website and in the USGS Annual Report.
