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 complete the development of two watershed HSPF models for the Mustinka River and Bois de Sioux River watersheds. These calibrated and validated executable models will simulate hydrology at the 12-digit HUC subbasin scale.
The Mustinka River winds through five counties in west central Minnesota and empties into Lake Traverse, a border waters lake with excellent fishing and recreational opportunities. For several years, sections of the river have been impaired for turbidity due to too much soil/sediment eroding from the land and washing away into the water. Excess sediment degrades aquatic habitat
and feeds algae blooms.
