Wetland sediments that are contaminated with hydrophobic organic compounds, such as dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs) can be remediated via in-situ methods. Four different amendment agents, activated carbon, zero valent iron, organoclay and seaweed were assessed. Activated carbon provided the greatest reduction in both PCB and DDx porewater concentrations: an average of 90% or greater reduction of the six congeners detected. Two amendment delivery technologies were evaluated in a microcosm experiment: a granular activated carbon slurry and Aquablok containing powdered activated carbon. The addition of activated carbon via both delivery techniques was found to significantly decrease PCB porewater concentrations (100% reduction).
