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 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.
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.
