Sediment and Dredged Material Treatment forms the second volume in the SEDNET mini-series, Sustainable Management of Sediment Resources. The volume asks "How can you achieve sustainable sediment treatment?". In fact, before this question can be answered, many steps have to be considered beforehand. This book tackles the questions and issues which arise when looking at the various steps involved. This volume is applicable to a wide audience, from students at the graduate level, to experienced researchers and laboratory personnel in academia, industry and government. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. Gives a broad overview on sediment treatment with a European perspective Suitable for those new to sediment treatment as well as specialists in the field Provides an overview on the costs involved in sediment treatment

This paper describes the dredging and upland disposal of about 30,000 cub. m of polychlorinated biphenyl (PCB)-contaminated (>10 ppm) dredged material for the purpose of determining a treatment method that is safe and does not induce secondary contamination. A cutterless pump dredge was used, and the dredged material was transferred to the discharge basin by pipeline. The dredging depth averaged 76 cm, as compared with the planned depth of 70 cm. No increase in turbidity was observed during dredging. The basin was subdivided, and the residual water treatment was carried out by transferring the dredged material alternatively to each basin, where dredging and plain sedimentation were conducted. The segregated water was sand filtered. About 400,000 cub. m of water was disposed, with turbidity under 10 degrees (draining standard was below 30 degrees) throughout the work. The final disposal was made by draining the disposal area, surrounding it with embankment, and covering with impervious sheeting. The dredged material was allowed to solidify, and the surface was covered with sand and gravel and sealed with asphalt.

"During the latter part of the 20th century it became clear that another approach should be found for handling contaminated dredged material. Up to then it was common practise to dispose dredged material at sea or use it to raise the land or as fertilizer on land. A new approach was to store contaminated dredged material in confined disposal facilities (CDFs). These CDFs are only meant for dredged material that is heavily contaminated and cannot be relocated into the water system or used for engineering or environmental purposes. Much effort was devoted to the design of CDFs and to the assessment and management of environmental risks. Despite the fact that stricter environmental pollution controls meant that sediments in rivers and harbours became less contaminated and options for use of dredged material became more available, there still is the need for more storage capacity for contaminated dredged material arising from certain capital, environmental remediation and sometimes maintenance dredging projects. It is especially difficult to decrease the influence of diffuse sources on contamination levels of sediments."--Introduction.

The Craney Island Management Plan was developed to extend the life of the Craney Island Dredged Material Management Area (CIDMMA). The CIDMMA is used to dispose maintenance and new work dredged material from the project area. With current practice, CIDMMA would reach ultimate capacity by the year 2000. If, however, suitable material is barged to the sea and only contaminated material is placed in the facility (Restricted Use Program), then the life of the facility can be extended. Two tasks were addressed in this study: (a) determine service life under Restricted Use and (b) determine contaminant losses and conduct a Comprehensive Analysis of Migration Pathways (CAMP) expected to occur under Restricted Use. The results showed that the service life of the CIDMMA could be extended under Restrictive Use for approximately 140 years under baseline coniditions or 90 years under Worst Case conditions. The CAMP analysis was conducted along three major contaminant migration pathways (effluent, leachate, and volatile). Effluent was the most significant pathway for metal losses and volatilisation and for polynuclear aromatic hydrocarbon (PAH) losses. Leachate losses under a fully dewatered condition would not exceed effluent losses for some metals. PAH losses for a fully dewatered condition would not exceed effluent losses.

Dredged Material and Mine Tailings are two of the same thing once they are deposited on land: they must be safe-guarded, wash-out must be prevented, and they must be protected by a plantcover. This comprehensive two-volume treatise covers both important aspects of their management: Environmental Management of Solid Waste turns to the practical applications, such as prediction, restoration and management, while in Chemistry and Biology of Solid Waste the principles and assessment are scientifically studied and discussed. Previously, dredged material was a commodity, it could be sold as soil, e. g. to gardeners. In the meantime, dredged material from the North Sea (e.g. the Rotterdam or Amsterdam harbor) must be treated as hazardous waste. Many environmentalists, managers and companies do not know how to solve the inherent problems. This new work deals with the chemical, physical and biological principles; the biological and geochemical assessment; the prediction of effects and treatment; and finally, with restoration and revegetation. It is written by many leading scientists in the various fields, and will prove invaluable for managers and politicians who are concerned with the present environmental situation.
