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 Lake of the Woods (LOW) Total Maximum Daily Load (TMDL) study will: (1) identify water quality goals for the Minnesota portions of the LOW/Rainy River Watershed; (2) recommend nutrient allocations to achieve TMDLs where waters do not meet standards; and (3) provide opportunities for stakeholders to engage in the process of watershed-management planning to adopt protection and restoration strategies. The project will include existing in-lake and watershed model updates, TMDL component development, restoration plan development, and public participation.
This project is to conduct water chemistry monitoring at two subwatershed sites and two major watershed sites in 2016 and 2017 based on flow conditions, targeting runoff events using protocols defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to Minnesota Pollution Control Agency (MPCA) and used for calculating pollutant loads.
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.
