The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
Project between Minnesota Department of Natural Resources and United States Army Corp of Engineers at Knowlton Creek Watershed to address a large amount of sediment deposited into the St. Louis River Area of Concern (AOC).
The Minnesota Department of Natural Resources will coordinate the collection of high-resolution elevation data for northeastern portion of Minnesota using Light Detection and Ranging (LIDAR) systems. The geographic area of the work includes Minnesota counties of Carlton, Cook, Lake, and St. Louis Counties and that portion of Koochiching County that comprises Voyageurs National Park.
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.
For this project, the St. Louis River Alliance will complete the data set for the water quality assessment of six streams in the Lake Superior Basin. These streams include the French River, Talmadge River, East Split Rock River, Skunk Creek, Chester Creek and Tischer Creek.
