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 respond to public notice comments received after a 2nd comment opportunity and several requests for changes to the Total Maximum Daily Load (TMDL) report and petition for contested case hearings (CCH). Additional review work must be completed and if necessary, edits or updates to the TMDL and Watershed Restoration and Protection Strategy (WRAPS) reports. If there are substantial changes to both documents another public noticing will be necessary.
This project continues the total maximum daily load (TMDL) and watershed restoration and protection strategies (WRAPS) process for the Duluth Metropolitan Area (DMA). The DMA is defined by water, sitting at the juncture of Lake Superior and the St. Louis River Estuary, and surrounded by semi-mountainous terrain. The project serves as a bridge into the next phase of restoration and protection identified by the Duluth Urban Stream TMDLs and WRAPS. In the first phase of community engagement, a collaborating organization was formed to define a framework for the DMA communities.
Several streams within the Duluth metropolitan area are identified as impaired and are included on Minnesota’s Impaired Waters List, with impairments to Aquatic Recreation, due to levels of Escherichia coli (E. coli) bacteria. Total Maximum Daily Load (TMDL) studies have been completed (draft) for these impairments, including Keene Creek and Tischer Creek. The goal of this project is for the City of Duluth to provide the Minnesota Pollution Control Agency (MPCA) with information on the sources of E.
Four beaches along the North Shore of Lake Superior and within the Duluth Harbor have aquatic recreation impairments due to high concentrations of E. coli, a bacterial indicator of fecal contamination. The project area includes portions of the Lake Superior South and St. Louis River watersheds near Duluth. Several of the beaches are also listed as impaired for beneficial use (due to fecal bacteria) as part of the St. Louis River Area of Concern.
Minnesota Pollution Control Agency (MPCA) Watershed Pollutant Load Monitoring Network (WPLMN) requests assistance from local partners to collect samples and field data at designated stream monitoring sites for the purpose of assessing water quality and calculating annual pollutant loads.
The overall goal of this project is to perform water quality monitoring and load calculation duties to accomplish Minnesota Pollution Control Agency (MPCA) Watershed Pollutant Load Monitoring Network (WPLMN) monitoring efforts at the seven sites within the Redwood and Cottonwood River watersheds as well as the Minnesota River site near Morton. To accomplish this goal the requested funds will provide for technician’s time, mileage, lab costs, supplies, as well as equipment calibration and upkeep.
The purpose of this contract is to augment data collection efforts for the St. Louis River (SLR) Watershed Restoration and Protection Strategy (WRAPS) and for four impaired Duluth beaches. For the SLR WRAPS, activities include: attaining datasets for watershed stressors and geomorphic conditions, water quality gap monitoring, and a civic engagement component. Impaired beaches activities include: collection of field observational data, field water chemistry, and water quality samples for analytical analysis.
Beginning in June 2019, the St Louis River Watershed will start the second round of the Watershed Restoration and Protection Strategies (WRAPS) process. This project helps the Carlton County SWCD (SWCD) initiate a broader citizen participation process in the Watershed. The SWCD staff will be enabled to create a greater degree of public interest in and awareness of the general health of the Watershed. This work will create the foundation for greater citizen involvement in the planning and implementation of restoration and protection activities in the Watershed.
The project provides the opportunity for the North Saint Louis Soil and Water Conservation District (NSLSWCD) to engage in efforts to increase public participation in the St. Louis River Watershed and participate in the planning and technical review of the Watershed Restoration and Protection Strategies (WRAPS) process. NSLSWCD contains the headwaters of the St. Louis River Watershed. The District’s knowledge of the area, communities, and organizations puts them in a unique position to work cooperatively in the watershed.
The goal of this project is to extend existing Hydrologic Simulation Program FORTRAN (HSPF) models through 2017 for the following major watersheds: Redwood, Cottonwood, Watonwan, Blue Earth, Le Sueur, Pomme de Terre, Minnesota River-Headwaters, and Lac Qui Parle watersheds.
This St. Louis River Watershed assessment will include the waters of Dempsey Creek, West Two River, St. Louis River, Mud Hen Creek, Embarrass River, West Swan River, Partridge River, Barber Creek, East Swan River, Helen Lake, Pine Lake, Cadotte Lake, Colby Lake, Loon Lake, St. James Pit, Strand Lake, Nichols Lake, Ely Lake, Silver Lake, Elbow Lake, Mashkenode Lake, Carey Lake and Island Lake. These lakes and streams are found throughout the St. Louis River Watershed, which spans parts of St. Louis and Itasca Counties.
The goal of this project is to development a Total Maximum Daily Load (TMDL) study that addresses all of the non-mercury-related impaired reaches along the Red River of the North (RRN). The TMDL study will provide an analytical and strategic foundation for recommending restoration strategies for impaired waters. This phase of the project will also include civic engagement efforts by providing water quality framework and stakeholder activities for civic/citizen engagement and communication.
The activity is for sediment sample preparation for cores collected at AGP/Northland Slip (AGP) and Azcon/DSPA Slip (Azcon) located in the St. Louis River (SLR) Area of Concern (AOC) in Duluth, Minnesota.
In accordance with a request from the Minnesota Pollution Control Agency (MPCA), Bay West, LLC (Bay West) will perform remedial investigation activities for Munger Landing, a sediment contamination site, located in the St. Louis River (SLR) Area of Concern (AOC) in Duluth.This activity will compile new 2018 data with existing data and generate updated figures and tables to support the remedy decision for the site.
This activity is for benthic bioaccumulation testing, benthic tissue analysis, and physical/chemical sediment analysis as part of the bioaccumulation study at the Mud Lake West site located in the St. Louis River (SLR) Area of Concern (AOC) near the Duluth area and one reference site at the request of the Minnesota Pollution Control Agency (MPCA).
The activity is for bench scale sediment sampling to be collected at the AGP/Northland Slip (AGP) and Azcon/DSPA Slip (Azcon) located in the St. Louis River (SLR) Area of Concern (AOC) in Duluth, Minnesota.
This project will collect water quality data in the St. Louis River watershed as part of the 10-year Watershed Restoration and Protection Strategy (WRAPS) cycle for Minnesota waters. South St. Louis Soil and Water Conservation District (SSLSWCD) staff will conduct all monitoring in accordance with Minnesota Pollution Control Agency (MPCA) Intensive Watershed Monitoring (IWM) standard operating procedures. The SSLSSWCD has extensive experience in stream sampling techniques, including dissolved oxygen, pH, specific conductance, temperature, total suspended solids, nutrients, E.
