Long Term Management of Confined Disposal Facilities for Dredged Material by Anonim Book PDF Summary
"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.
