■ Remove and dispose of 45,000 cubic yards of sediment from the Authority’s stockpile site in Delaware Township, Hunterdon County, NJ.

Dredging

Dredging Technologies Evaluated

■ Mechanical Excavation (in the dry);

■ Mechanical Dredging (in the wet);

■ Hydraulic Dredging with Mechanical Dewatering;

■ Hydraulic Dredging with Geobags.

Dredge Material Characterization

■ Chemical analysis of the target materials meet State non-residential re-use standards with a portion also meeting re-use standards at residential sites. Vanadium and benzo(a) pyrene was observed in some samples at higher than residential levels, but within known criteria for site-specific brownfield reuse;

■ Elutriate (filtrate water) samples from bench-scale dewatering tests concluded that direct discharge to the Canal would achieve surface water standards. Treatment (such as filtration) to remove suspended solids may be required to improve the return water quality.
