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 purpose of this work is to develop Total Maximum Daily Loads (TMDLs; a federal clean Water Act requirement) for streams and lakes in the Kettle River and Upper St. Croix watersheds. This and other technical information will be used to develop a separate report called a Watershed Restoration and Protection Strategy (WRAPS) report.
Previous research by the St. Croix Watershed Research Station (SCWRS) has identified lake physics (temperature and oxygen) and nutrient recycling (nitrogen and phosphorus) as key drivers of lake algal blooms. SCWRS will conduct monitoring consistent with the prior research efforts by re-deploying three moored buoys to collect data throughout the 2019 ice-free season, including surface water samples. Additionally, SCWRS will deploy an in situ flourometer to measure total algae and cyanobacteria concentrations and will collect and analyze cyanobacterial toxins.
The purpose of this contract is to establish an international watershed coordinator for the Rainy River- Lake of the Woods (RR-LOW) watershed. The coordinator will assist the Minnesota Pollution Control Agency (MPCA) in facilitating and enhancing civic engagement and public participation activities through collaboration and integration of the efforts of groups working on watershed activities at local, state/provincial, tribal, and bi-national levels.
