Environmental effects of overboard spoil disposal
Navigation channel improvements along reach of 14 km in upper Chesapeake Bay required that approximately 4.5×106 cu m of silt and clay be dredged and spoil deposited in shallow water 1000 m west of dredging site; biological and geological studies were performed on 3 km test section of planned work involving 1.3×106 cu m of spoil deposited in shallow water; results indicate that measurable quantities of suspended sediment extended 4 km from disposal point, that spoil on bottom did not remain within limits of disposal area, and that dissolved nutrients contained in spoil sediment pore-water were probably released to environment.
