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.
Phase 4 of the Lake Winona Total Maximum Daily Load (TMDL) project will finalize the draft Lake Winona TMDL, dated November 2009, by completing additional data analysis, lake quality modeling, updating the TMDL report, and supporting the public involvement process.
This project will obtain a lake data set for Douglas County while fostering lake association participation, ownership, and understanding of their lakes. A better understanding of these lakes is necessary in order to meet goals established in the 2009-2019 Comprehensive Local Water Management Plan and enable 303(d) and 305(b) assessments. Lakes included in this project are: Agnes, Alvin, Blackwell, Brophy, Charley, Cook (Cork), Crooked (East), Crooked (NW), Echo, Henry, Lovera (Lovers), Mina, Round, and Spring.
