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 quantify and qualify the effectiveness of herbicide treatments and native plant re-establishment at Duck Lake through systematic vegetative surveys pre and post herbicide application and following mid-summer die-off of curly-leaf pondweed. The data and analysis will ultimately be used in the development of TMDLs, implementation and protection strategies for other lakes in the Middle Minnesota Major Watershed.
This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
The Seven Mile Creek Condition Monitoring project will maintain and build on the continuous flow and water quality data base at three stream sites and one county tile in the Seven Mile Creek watershed through the collection of approximately eighty five water samples per monitoring season in preparation for the Middle Minnesota Intensive Watershed Monitoring scheduled to begin in 2013.
This project will further assess the water quality within Brown County by monitoring its rivers, streams, ditches and other waterbodies. This project will also be working in cooperation with individual volunteers to perform grab samples and visual assessments of seven waterbodies throughout Brown County.
