Since the formation of the Detroit River Area of Concern (AOC) in the late 1980's and the rollout of the 1991 RAP Report, the Detroit River Public Advisory Council (PAC) has been working to address the effects of contaminated sediments in the Detroit River and their impact on the removal of Detroit River Beneficial Use Impairments (BUIs). For decades, EPA, MDEQ and other state and federal agencies have worked on various sediment remediation projects along the Detroit River, with little coordination with the PAC, and without any prioritization given towards remediation projects with respect to the PAC's efforts to remove BUI's related to contaminated sediments.


This project provided, for the first time, a systematic effort to gather available contaminated sediment data, create a mutually agreed upon hazard ranking system and put the information into a GIS mapping system. Collected data was used by the EPA, MDEQ, PAC and other expert stakeholders to reach consensus on a definable set of sites along the Detroit River that need to be addressed enabling the PAC to move the contaminated sediment related BUI removal process forward.


From this point forward EPA, MDEQ and the Detroit River PAC will work together in strategizing steps to assess each site and to verify the existence of contaminates indicated by the project data. Where needed, additional verification sampling will be completed. Upon final verification of this project's "preliminary assessments", efforts will be initiated to develop contaminated sediment remediation and / or removal projects to address these sites.


As a primary project "deliverable", an info-graphic was created in poster format depicting the process and findings of the study along with a synopsis of recent progress regarding remediation of contaminated sediments in the Detroit River. The sequence of work to prepare this document is summarized in the final report.
