Abstract:

Contaminated sediments in the world's waterways present a variety of problems, both economic and environmental. The two basic problems are waterways which need maintenance dredging to allow commerce to continue, and sites which require cleanup for environmental and public health considerations. Sediment management is a process by which the stakeholders in a given project determine the best strategy available for remediation or cleanup of the site. A three step process of assessment, management/remediation and monitoring is used to deal with each individual project. The strategies in the management/remediation step are divided into in situ, or in place, management of the sediments, and ex situ management, which involves removing the contaminated sediments from the site. Various case studies illustrate the many different ways to solve these problems, including the Mud Dump Site in New York, Waukegan Harbor on Lake Michigan, and Boston Harbor in Massachusetts.
