The purpose of this volume, Processes, Assessment and Remediation of Contaminated Sediment, 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.  Topics addressed in this volume include: ·         An introduction to contaminated sediment management that summarizes the tradeoffs between natural attenuation, containment and active removal (Chapter 1). ·         A series of chapters describing key sediment processes that separate sediments from contaminated soil sites and make understanding sediment processes difficult: ­          An introduction to the processes that are uniquely associated with contaminated sediment sites including sediment resuspension, groundwater upwelling, hyporheic exchange and bioturbation (Chapter 2). ­          The current understanding of sediment erosion and transport and how these processes are modeled (Chapter 3). ­          A description of the physical and biological processes operative at the sediment-water interface (Chapter 4). ·         A series of chapters describing sediment risk assessment approaches including: ­          How to design risk assessment programs to support risk management decisions (Chapter 5). ­          The biological effects that usually define the risks that contaminants in sediments represent and the biological assays used to assess those risks (Chapter 6). ­          Assessing bioavailability via chemical measurements, primarily through the use of porewater concentration measurements (Chapter 7). ·         A series of chapters describing sediment risk management, i.e., remedial approaches and their design, including: ­          Processes describing how to develop and implement risk management efforts (Chapter 8). ­          Each of the key approaches to managing contaminated sediments; monitored natural recovery (Chapter 9), intrinsic biotransformation and biodegradation (Chapter 10), in situ treatment via carbon amendments (Chapter 11), in situ containment via capping with either inert material or with active amendments (Chapter 12) and dredging and excavation (Chapter 13). ­          The design and implementation of a monitoring program to evaluate remedy performance (Chapter 14). Each chapter in this volume has been thoroughly reviewed for technical content by one or more experts in each of the subject areas covered. The editors and chapter authors have produced a well-written and up-to-date treatise that we hope will be a useful reference for those making decisions on the assessment and remediation of contaminated sediments and for those involved in research and development of advanced technology for the assessment and remediation of sediments.

Contaminated sediments pose some of the most difficult site remediation issues. Contaminated sediments typically reside in spatially variable and dynamic systems subject to seasonal flow variations and episodic storm events. The volume of sediments that must be managed at particular sites often exceeds one million cubic meters, dwarfing many contaminated soil sites. These sediments are also associated with equally daunting volumes of water and efforts to remove the contamination typically entrains even more water. The environmental security of both NATO and partner countries is at risk due to the pervasive nature of sediment contamination of rivers, lakes and harbors. A NATO Advanced Research Workshop was convened in Bratislava in May 2005 to discuss current approaches to managing contaminated sediments and to identify research necessary to overcome outstanding problems. In this text, drawn from presentations and discussion of that workshop, current approaches to the assessment and remediation of contaminated sediments will be discussed with the emphasis on in-situ management. Physical, chemical and biological approaches for the assessment and remediation of sediments are all addressed. Developing regulatory and strategic approaches are highlighted with a special emphasis on the potential for biological remediation for the management of contaminated sediments.
