New Bedford Harbor Superfund Project, Acushnet River Estuary Engineering Feasibility Study of Dredging and Dredged Material Disposal Alternatives. Report 11. Evaluation of Conceptual Dredging and Disposal Alternatives
Abstract
This report evaluates conceptual dredging and disposal alternatives for the Acushnet River Estuary, a part of the New Bedford Harbor Superfund Site. Dredging for removal of the highly contaminated sediment and subsequent disposal in upland or nearshore confined disposal facilities or disposal in contaminated aquatic disposal facilities are alternative considered in the Engineering Feasibility Study of Dredging and Dredged Material Disposal Alternatives. Sediment testing and sediment transport modeling performed as earlier tasks of the study form the basis for evaluation of the alternatives. The technical feasibility of conceptual design options is based on site availability, capacity, and characteristics and on sediment physical characteristics and dredged material settling behavior as defined by laboratory testing. Contamination releases during dredging and disposal operations are estimated for each disposal option. A preliminary cost estimate for implementation of each option evaluated is also presented. Keywords: Confined disposal facility, Contained aquatic disposal, Metals, Polychlorinated biphenyl.
