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.
Four stream segments, totaling over 100 miles, are impaired in the Little Fork River for Total Suspended Solids (TSS). This study will provide local partners with project options for reducing sediment in the Little Fork Watershed. Through the use of sediment fingerprinting determinations can be made if the sediment is from in (or near) channel, or the watershed and identify what sub-watershed the sediment is coming originating.
The Little Fork River and Big Fork River - USGS FLOWSED project was established to collect site specific data for streamflow, SSC, and bedload at the Littlefork and Big Fork Rivers in Northern Minnesota; use the data to evaluate the use of dimensionless sediment rating curves for the rivers; and document the results of the study in conjunction with the results from other rivers in the state for the application of regional sediment rating curves to rivers in Minnesota.
Koochiching County has seven major watersheds in the county, this contract is for work in five of them: Big Fork, Little Fork, Rapid River, Lower Rainy River, and Rainy River Headwaters. The local Koochiching County Soil and Water Conservation District (SWCD) is positioned to assist in several elements of the Watershed Restoration and Protection Strategies (WRAPS) process. This includes gap monitoring for water chemistry, sediment work, Total Maximum Daily Load (TMDL) development, modeling scenarios, and WRAPS development.
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.
