Deposit N
Demonstration project


Background and Purpose

The Wisconsin Department of Natural Resources and the U.S. Environmental Protection Agency sponsored a PCB contaminated sediment removal demonstration project from the Fox River at sediment Deposit N, located near Little Chute and Kimberly, Wisconsin.

Deposit N was located upstream of the Cedars Dam. Deposit N covered an area of 3 acres and contained about 11,000 cubic yards of sediment with a maximum concentration of 186 ppm. The sediment deposit averaged 2-3 feet thick, above fractured bedrock, in water depths of about 8 feet. A site Remedial Investigation (RI) was completed for Deposit N in November 1996 and a Feasibility Study (FS) was completed in April 1997. The RI/FS forwarded the remediation alternatives of dredging and containment to the WDNR. Subsequently, the WDNR selected removal of sediments by dredging as the technology for this demonstration project. In 1997 Foth & Van Dyke of Green Bay, Wisconsin was hired as the project design and construction oversight contractor to guide the implementation of this sediment removal project.

Following site mobilization activities, actual sediment removal work at Deposit N occurred in November/December 1998, and again from August to October, 1999. Following the completion of work to project specifications, additional work was performed in October and November 1999 at Deposit O, an adjacent contaminated sediment deposit.

A Summary Report was published in April 2000. A companion document, Appendix to Summary Report published in April 2001, contains additional data and technical support information for the sediment removal work at Deposit N.

The Appendix to Summary Report presents the latest information and analytical results of the project. Additional data analysis since the April 2000 report has resulted in slight changes to the project's removal metrics. These changes are not substantive and do not affect the conclusions of the the project as presented in the April 2000 report.
