In this report, the National Research CounciT's Committee on the Remediation of PCBContaminated Sediments reviews the nature of the challenge; provides an overview of current knowledge about the inputs, fates, and effects of PCBs; recommends a riskbased framework for assessing remediation technologies and risk-management strategies; elaborates on this framework as it applies to PCB-contaminated sediments specifically; and provides recommendations for research that should enhance the nation's ability to manage PCB-contaminated sediments effectively. This chapter briefly reviews why PCBs in sediments are of environmental concern, states the tasks addressed by the committee, sets forth the committee's activities and deliberative process in developing the report, and explains the organization of the report.

if PCB concentrations must be reduced, how much reduction is needed, and what is the best approach to achieve the reduction? What are the immediate and the long-term human health and ecological risks associated with the various processes to reduce PCB concentrations both locally and for a wider geographic area?

· For a few selected sites and using the framework, estimate human and ecological risks associated with each ofthe specified remediation approaches for contaminated sediments containing PCBs in light ofthe availability, costs, and effectiveness of the various approaches. · Where applicable, recommend areas for future research.

The committee emphasized, however, that its purpose in visiting the contaminated sites was not to solve or recommend any solutions for any specific site, but to obtain information that would be valuable for addressing the management of PCB-contaminated sites nationwide. The committee also reviewed written materials submitted by EPA; state and local government agencies; affected industries, such as the Fox River Group and General Electric Corporation; environmental groups, such as the Scenic Hudson and Sierra Club; numerous business and community groups; American Indian organizations; and many concerned and knowledgeable individuals.

Therefore, the committee finds that it is inappropriate to make generalizations about the effectiveness of an option for a particular site without detailed knowledge of that site. The committee is aware that many readers expect this report to recommend risk-management options that are most suitable for reducing the risks associated with PCB-contaminated sediments or that would be most applicable to specific sites.
