Abstract:

The sediments in New York Harbor are contaminated with a wide variety of chemical constituents. Results of testing conducted in accordance with the EPA Ocean Dumping Criteria by several permit applicants in 1979 indicated a bioaccumulation potential for PCB in the marine worm being tested. Approximately 650,000 cubic meters of material dredged from the projects were precision dumped at a tautmoored buoy located in about 27 meters of water in the Atlantic Ocean. The deposit was then capped with approximately 1.4 million cubic meters of uncontaminated dredged material in an attempt to isolate the contaminated sediments from the marine ecosystem. Studies were initiated to determine the stability of the capped mound and the biological effectiveness of the cap. An additional study was initiated to determine a unique chemical signature for the disposal sediments such that the burial location of the contaminated sediments could be identified and subsequently monitored if necessary. The studies are all presently ongoing with final results due in early 1982.
