This project will provide fiscal resources for South St. Louis County Soil and Water Conservation District (SSLCSWCD) to participate and lead efforts to attain geomorphic data sets, dissolved oxygen assessments, culvert inventory, and civic engagement activities in three major watersheds, Nemadji River, South Lake Superior and St. Louis River. This work is currently being worked on as a part of the MPCA’s Watershed Restoration and Protection Planning efforts.
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.
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.
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.
