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:

­          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).
