This book was released on 1976 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The disposal of both freshwater and saltwater sediments in open waters has been experimentally investigated in the laboratory. The emphasis of the experimental work was directed towards identifying the role that sediment organic carbon has in controlling various water-quality parameters at disposal sites. Long-term studies examined the possibility of transport of material from sediments into an overlying water column as well as monitoring the changes in the aqueous phase which initially contained large amounts of suspended matter. For the latter case, metal and nutrient concentrations were initially high but decreased significantly with time. Exceptions to this behavior were noted. Specific components were identified which migrated from the sediment into the water column. They include ammonium-nitrogen, orthophosphate, cadmium, and manganese, the latter only in seawater media. Organic carbon and inorganic nitrogen underwent transformations with the systems investigated. Both sediment organic carbon and soluble organic matter were generally found to have no demonstrable effect on water quality. Exceptions to this general conclusion were found in two sediments containing significant amounts of petroleum hydrocarbons.

This book was released on 1978 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
