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 is for constructing, calibrating, and validating a Hydrologic Simulation Program FORTRAN (HSPF) watershed models for the Minnesota portions of the Des Moines Headwaters, Lower Des Moines, and East Fork Des Moines watersheds. The model can be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) reports. This model generates predicted output timeseries data for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with observed data.
The Rainy River - Rainy Lake, Rainy River - Baudette and Rapid River Watershed Assessments will include the waters of the Baudette River, Black River, Peppermint Creek, Rapid River, Rat Root River and Winter Road River in Koochiching and Lake of the Woods Counties. This assessment focuses on collection of water chemistry and field parameters at the 12 key sites identified and modified by the Minnesota Pollution Control Agency (MPCA). Five of the sites will have extra total phosphorus and chlorophyll analysis completed as identified by the MPCA for collecting river nutrients.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
This project will provide an important framework for civic and citizen engagement and communication in the International Rainy River-Lake of the Woods Watershed, which will contribute to long-term public participation in surface water protection and restoration activities.
