Evaluation of Dewatering Strategies for PCB-Contaminated Sediments in the Great Lakes Region

Objectives:  PCB-contaminated sediments from the Ashtabula River will be used for this project. The results and recommendations are expected to be generally applicable to similar future cleanup efforts in the Great Lakes region. 1) To determine the distribution of contaminants associated with different particle size fractions of the Ashtabula River sediments. 2) To determine the kinetics of contaminant release from the different sediment components during dewatering of these sediments. 3) To determine the limits of success that can be expected from the addition of admixtures to the Ashtabula River sediments. 4) To determine the optimal method for removal of pore water from the Ashtabula River sediments and treatment of the aqueous effluent.
