The reason why we mention all these historic industries and historic input is that makes the site that much more complex. Different types of activities mean different types of chemicals are in those sediments.... We were able to focus on a few [contaminants], and there are others that are co-located. If we clean up for PCBs, mercury, PAHs, and in some cases pH, we'll pretty much be able to get all of the contamination."

The proposed project area hugs the western shoreline of the channel. It begins at the BASF Northworks facility and continues south to the MPI Facility near the Grosse Ile Toll Bridge.
The Upper Trenton Channel project is currently in the design stage. The start time for the cleanup is TBD. Once a project is agreed to, the remediation will likely take one to two field seasons to complete.
Check back after the design phase for a more complete schedule.
Sediment to be remediated: 215,00 cubic yards
Contaminants: PCBs, mercury, PAHs, NAPL, high pH & chloronaphthalenes
Method: Dredging (hydraulic and mechanical) and sand cover
When: TBD, depending on a non-federal sponsor to provide matching funds for the cleanup stage
Partners: U. S. Environmental Protection Agency, BASF Corp., Arkema Inc., Union Carbide Corp.
Cost: TBD during design
Note: 14,000 cubic yards are hazardous (TSCA) for PCBs and will require additional management.
The project is currently in design. More technical information will be provided once it's available.
