Sediments Contamination And Sustainable Remediation

Although valuable resources in river basins and other aqueous environments, sediments often receive much less attention from researchers, policymakers, and other professionals than other components of the ecosystem. Until now. Highlighting the important role that sediments play in the geoenvironment, Sediments Contamination and Sustainable Remediation focuses on sediment management for the purpose of environmental cleanup or management. It provides the in-depth understanding of the sediment-water environment needed to develop better management practices and meet sustainability requirements. The book discusses the contamination of sediments resulting from discharge of pollutants, excessive nutrients, and other hazardous substances from anthropogenic activities. It examines impacts observed as a result of these discharges, including the presence of hazardous materials and eutrophication, and elucidates the remediation techniques developed to restore the health of sediments and how to evaluate the remediation technologies using indicators. The text explores the problems inherent in dealing with contaminated sediments in rivers, lakes, and estuaries and includes numerous case studies that illustrate key concepts. The authors provide wide-ranging coverage of the topic and include methods for evaluating the effectiveness of different remediation technologies. They make the case for the development and application of innovative management practices that create long-term solutions to sediment contamination to reduce natural resource depletion, continued landfill contamination, and diminished biodiversity in the aquatic geoenvironment.

The purpose of this book is to help engineers and scientists better understand contaminated sediment sites and identify and design remedial approaches that are more efficient and effective. Contaminated sediment management is a difficult and costly exercise that is rarely addressed with easily identified and implemented remedies. It is hoped that this book can help identify and implement management approaches that provide an optimal, if not entirely satisfactory, solution to sediment contaminant problems.​

The pervasive, widespread problem of contaminated marine sediments is an environmental issue of national importance, arising from decades of intentionally and unintentionally using coastal waters for waste disposal. This book examines the extent and significance of the problem, reviews clean-up and remediation technologies, assesses alternative management strategies, identifies research and development needs, and presents the committee's major findings and recommendations. Five case studies examine different ways in which a variety of sediment contamination problems are being handled.

"Twenty-three peer-reviewed papers provide the latest global information on environmentally sound solutions to the sustainable management and remediation of contaminated sediments. Papers address: Coverage of contaminated sediments by structural features or fixing agents ; Neutralization by dredging, treating, and re-deposition of the sediments in place ; Dredging by off-site encapsulation ; Encapsulation of the sediments along the shore by dredging, accumulating, and covering. It also includes several interesting case studies for important projects being conducted in Ireland, Scotland, Malaysia, Turkey, Japan, Canada, and the USA."--Publisher's website.

Contaminated marine sediments threaten ecosystems, marine resources, and human health. They can have major economic impacts when controversies over risks and costs of sediment management interfere with needs to dredge major ports. Contaminated Sediments in Ports and Waterways examines management and technology issues and provides guidance that will help officials make timely decisions and use technologies effectively. The book includes recommendations with a view toward improving decision making, developing cost-effective technologies, and promoting the successful completion of cleanup projects. The volume assesses the state of practice and research and development status of both short-term and longer-term remediation methods. The committee provides a conceptual overview for risk-based contaminated sediment management that can be used to develop plans that address complex technological, political, and legal issues and the interests of various stakeholders. The book emphasizes the need for proper assessment of conditions at sediment sites and adequate control of contamination sources.

Volume 9 of the series presents 38 technical papers covering a wide range of environmental issues, including Bioremediation, Chemical Oxidation, Heavy Metals, MTBE, Phytoremediation, Radiation, Regulatory and Legal issues, Remediation, Risk Based Cleanup and Site Assessment. Contributing authors are drawn from across the spectrum of interest: government agencies, academic institutions, the consulting community and industrial companies.
