Evaluation of Bioaccumulation Control in Aquatic Sites Using Activated Carbon

Sediments in the urban harbors often exhibit elevated levels of PCBs bioaccumulation, limiting their suitability for beneficial use or placement in aquatic sites. Amendment of dredged material in the bioactive zone with activated carbon has the potential to provide bioaccumulation control, permitting expanded use of aquatic placement where CDF capacity is being exhausted. Prior to this study, an application of activated carbon in a conventional mechanical dredging operation has never been demonstrated in a navigation dredging project.
