Evaluation of treatment, disposal, and managerial options for dredged sediments from newark bay, arthur kill, and newtown creek of new york/new jersey harbor and proposed design

摘要

The bay areas surrounding New York/New Jersey Harbor are naturally shallow, acting as catchments for river-transported sediments and solids from surface point and nonpoint sources. Dredging is required to maintain navigability for large cargo ships. Annually more than 5 million yd~3 of sediments has been dredged to maintain harbors and waterways for New York and New Jersey Harbor. Currently about 80 percent of dredge sediments are considered "clean" and ocean disposed of at the designated Mud Dump site, located approximately 6 nautical miles south of Rockaways.
