Saint Louis River Area of Concern - Minnesota Slip Dock Wall Investigation

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. Cleanup of contaminated sediments within MN Slip have been evaluated in a Focused Feasibility Study (FFS); however, the walls of the dock that surround the slip require assessment to determine if potentially contaminated soil within the walls is an ongoing source of contamination in the slip. This project includes field work which will be conducted at Minnesota Slip in the SLR AOC. It includes a dock wall investigation, data review, quality assurance/quality control (QA/QC), data formatting, and data reporting.
