From purpose and scope: The main purpose of this monitoring was to gather several years of data on PCB concentrations preparatory to removal of contaminated sediments by dredging, which was originally scheduled for the early 1980's. Plans for dredging and disposal of sediments are currently being reevaluated. This report examines the contribution and transport of PCB's (polychlorinated biphenyls) from various reaches of the Hudson River and the changes in PCB concentration since 1977, when discharge was terminated. |
