Hennepin County will implement prioritized projects from the Rush Creek Subwatershed Assessment, including closing about 200 open tile intakes on the farms of 11 landowners, establishing 6 grassed waterways, two exclusion fence systems, and two contour farming conversions. These projects will significantly reduce bacteria loads upstream of Elm Creek Park Reserve where the creek serves as a learning laboratory for more the 2,500 students each year. In addion, these projects will reduce sediment by 616 tons per year and phosphorus by 478 pounds per year.
The MPCA and Wisconsin Department of Natural Resources (WDNR) are currently working together to implement a comprehensive long-term plan to delist the Saint Louis River Area of Concern (SLR AOC). Many of the Beneficial Use Impairments (BUIs) in the AOC are linked to the presence of sediment contaminants. The site consists of a former shipping slip in the Duluth Harbor that now serves as a private marina as well as the location of the William A. Irvin shipping vessel and museum.
The Minnesota Pollution Control Agency (MPCA) is currently working with the United States Environmental Protection Agency and private consultants as part of the Great Lakes Area of Concern (AOC) program to identify and remediate bed sediments contaminated with polychlorinated dibenzo-p-dioxins/dibenzofurans (dioxins) in reservoirs in the St. Louis River watershed of the Lake Superior Basin. Two reservoirs in the St. Louis River watershed where dioxins in bed sediments are a concern are Thomson and Scanlon Reservoirs near Cloquet, Minnesota.
The Minnesota Pollution Control Agency (MPCA) and Wisconsin Department of Natural Resources (WDNR) are currently working together to implement a comprehensive long-term plan to delist the Saint Louis River Area of Concern (SLR AOC). Many of the Beneficial Use Impairments (BUIs) in the AOC are linked to the presence of sediment contaminants. A Remedial investigation was completed at the Site and contaminated sediment was identified at the head of the slip. Based on a review of historical use around the Site, upland sources of contamination may exist around the Site.

This activity outlines a U. S. Geological Survey (USGS) and Minnesota Pollution Control Agency (MPCA) cooperative project, characterizing bed-sediment lithology, including sediment composition and thicknesses, in Thomson and Scanlon Reservoirs using geophysical methods.
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 purpose of this work order is to collect sediment samples which will then be analyzed for contaminants of concern, and the sediments will also be used as part of a bioaccumulation study.
Bay West will complete a supplemental sediment loading study for the Ponds Behind Erie Pier located in the St. Louis River (SLR) Area of Concern (AOC) in Duluth, Minnesota.
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.
