The primary goal of this proposal is to demonstrate the viability of a pneumatic tube mixing method for the processing and handling of contaminated navigational dredged materials from the NY/NJ harbor system. The AOMI/ JAFEC USA Group in collaboration with Weeks Marine will implement this pilot project by dredging 13,000 cubic yards of sediment at the Construction and Marine Equipment (CME) waterfront site in Elizabeth, New Jersey, and then transporting the raw, partially de-watered dredge to the processing site in Linden, New Jersey, and then placing the amended dredge in a permitted disposal facility and or in a beneficial re-use application. The process logistics, all laboratory and field testing, along with a final technical report will be managed by CAIT.
