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 sixth largest fresh water lake in the United States, Lake of the Woods has sustained significant shoreline erosion through a number of high water events, high inflows from the Rainy River, sustained strong NW winds, and erodible soils on the southern shore. This project implements strategies to protect and enhance private shoreline on the lake by addressing long-term shoreline management.
The goal of this project is to develop a Roseau Lake Water Quality Improvement Report that will include a prioritized, targeted, and measurable implementation plan that will improve water quality in the Roseau Lake watershed. The project will result in development of site specific implementation actions through use of the Prioritize, Targeting, and Measuring Application (PTMApp) and the Drained Wetland Basin Inventory terrain analysis methods.
Lake of the Woods (LOW) is a resource with local, regional, state, and international significance and is the second largest lake in Minnesota. Over the past three decades the Warroad River Harbor in LOW has experienced severe sedimentation problems. The sedimentation has led to frequent dredging to remove excess sediment and protect this vital resource. However, it is unsustainable to continue dredging the harbor without also addressing the sources of upstream sediment within the Warroad River watershed.
