The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during the contract period. There will also be 5 sites in the Red River Basin where mercury samples will be collected and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
