Project Highlights

Lower Passic River Dredging Pilot Project
Newark, New Jersey

• NJDOT, USEPA, and USACE completed an Environmental Dredging and Sediment Decontamination Technology Study in December 2005

• Cashman removed approximately 5,000 CY of sediments unsuitable for Open Water Disposal

• 8 CY “CableArm” environmental clam shell style bucket was used for excavation

• Bucket outfitted with a pressure transducer to maintain a bucket depth tolerance of ± 6 inches

• Sediments loaded into 3,000 CY hopper scows and transported to the Bayshore Recycling, Inc. facility

• Bayshore Recycling, Inc. held the materials for future remediation technology trials

• Proposed sediment processes included:

            • Endesco Clean Harbors attempted to thermally lock the                         contaminants into the material and thru this process produce             construction grade cement 

            • BioGenesis Enterprises Inc. propose a method that would use a             patented sediment washing technology to produce a manufactures             soil that could be used in multiple land-based applications.
