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 involves the water quality monitoring of, and data analysis for four major watersheds (8-digit Hydrologic Unit Codes) in the Rainy River Basin. This monitoring will assist in providing the water chemistry data needed to calculate annual pollutant loads for the Major Watershed Pollutant Load Monitoring Network (MWPLMN) and provide short term data sets of select parameters to other Agency programs.
The Koochiching County SWCD staff will collect water chemistry and field parameters at specific times to determine amount of contaminant load into each stream. These sites will coincide with locations where stream flow data is also being collected. This project will focus on watershed load monitoring in both the Big Fork and Little Fork River watersheds.
International Water Institute (IWI) staff will monitor 24 sites in the Bois de Sioux, Mustinka (2 sites), Buffalo (8 sites), Red Lake (4 sites), Sandhill (3 sites), Thief (2 sites), and Tamarac River (3 sites) Watersheds intensively over a 2 year period in an attempt to collect 25 samples per year at each site. If conditions allow for the collection of all planned samples, 1200 stream samples will be collected over the time period. Monitoring will include field measurements, observations, and at least three photographs during each site visit.
MN Legislative Clean Water Fund funding to engage citizens in local watershed monitoring, work with regional partners to promote understanding and protection of watersheds, and organize and facilitate gathering of scientific data all for the benefit of water quality in the Red River Basin.
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.
