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.
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 purpose of this project is to gain additional information about the amount of phosphorous flowing into Lake St Croix by implementing additional water quality monitoring and/or to reduce the amount of phosphorous entering Lake St Croix by the implementation of projects that will reduce phosphorus loadings. The St. Croix River Association (SCRA) will coordinate with a subgroup of the St. Croix Basin Water Resources Planning Team and other local resource experts on the identification and funding of comprehensive water monitoring and phosphorus reduction activities in the Lake St.
Koochiching County has seven major watersheds in the county, this contract is for work in five of them: Big Fork, Little Fork, Rapid River, Lower Rainy River, and Rainy River Headwaters. The local Koochiching County Soil and Water Conservation District (SWCD) is positioned to assist in several elements of the Watershed Restoration and Protection Strategies (WRAPS) process. This includes gap monitoring for water chemistry, sediment work, Total Maximum Daily Load (TMDL) development, modeling scenarios, and WRAPS development.
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.
