Duluth area streams received over 10 inches of rainfall on June 19 and June 20, 2012. This "500 year event" provides a once in a lifetime opportunity to further understand sediment movement and stream channel alterations due to an event of this magnitude.
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.
The principal goal of this project is to fill critical data gaps and to establish a participatory watershed management framework for the Duluth Metropolitan Area (DMA) that mimics the statewide Watershed Restoration and Protection Strategy (WRAPS) process.
The Lake Superior Beach Monitoring and Notification Program exists to test recreational beach water and notify the public if bacteria levels become unsafe. This project will expand the Beach Program to include additional outreach efforts, sanitary surveys and testing of new technologies to improve the Beach Program. Monitoring results will be used to inform the public, find the sources of bacterial contamination and address polluted runoff from improper waste disposal.
The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
This project will generate water quality data for 10 stream locations MPCA designated for their 2012 and 2013 open-water sampling seasons (8 by NRRI-UMD and 2 via subcontract to the North St. Louis SWCD). The overall project goal is to collect event-based physical and chemical data sets for 10 agency-prioritized stream sampling sites in NE Minnesota for calculating pollutant loads and for incorporation into the overall State database for MPCA assessment purposes.
