Transport and Transformation of Contaminants Near the Sediment-Water Interface addresses the issue of contaminated bottom sediments and their potential adverse impacts on water quality. This state-of-the-science book covers regulatory management perspectives, physical processes, chemical and biological processes, and process synthesis/modeling. Specific topics discussed include EPA's Sediment Quality Criteria program from a regulatory perspective; flocculation, deposition, and resuspension of fine-grained sediments; approaches for measuring vertical sediment flux near the sediment-water interface; equilibrium models for metal speciation in natural sediments; the partitioning of organic chemicals in bottom sediments; and the development and application of models of sediment and associated contaminant transport in surface waters.
The significance of recent studies suggesting that interaction of contaminated bottom sediments with the overlying water play an important role in the long-term recovery of aquatic systems makes Transport and Transformation of Contaminants Near the Sediment-Water Interface essential for water quality engineers, environmental chemists, and environmental toxicologists. The volume provides important information for consultants, regulators, researchers, and graduate students as well.
