Book Description
Nine dredged material land containment areas, located at upland, lowland, and island sites, were monitored during hydraulic dredging operations in fresh- and brackish-water riverine, lake, and estuarine environments. Influent-effluent sampling at the diked disposal areas showed that, with proper retention of suspended solids, most chemical constituents could be removed to near or below background water levels. Most heavy metals, oil and grease, chlorinated pesticides, and PCB's were almost totally associated with solids in both the influent and effluent samples. The only chemical parameters which failed to show average decreases of less than 90 percent in total effluent samples include: titanium (89 percent), manganese (88 percent), potassium (78 percent), magnesium (64 percent), ammonium nitrogen (57 percent), mercury (46 percent), op DDE (46 percent), and pp DDE (21 percent). Effluent mercury and titanium frequently appeared to be mainly associated with
