This book provides a risk-based framework for developing and implementing strategies to manage PCB-contaminated sediments at sites around the country. The framework has seven stages, beginning with problem definition, continuing through assessment of risks and management options, and ending with an evaluation of the success of the management strategy. At the center of the framework is continuous and active involvement of all affected parties-particularly communities-in the development, implementation, and evaluation of the management strategy. A Risk-Management Strategy for PCB-Contaminated Sediments emphasizes the need to consider all risks at a contaminated site, not just human health and ecological effects, but also the social, cultural, and economic impacts. Given the controversy that has arisen at many PCB-contaminated sites, this book provides a consistent, yet flexible, approach for dealing with the many issues associated with assessing and managing the risks at Superfund and other contaminated sites.

Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.

In dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. A broad overview on sediment quality and impact assessment of pollutants Suitable for both newcomers to the field of sediment treatment and specialists alike Outlines practical examples of methods used in sediment quality analysis
