Contaminated Sediments: Characterization, Evaluation, Mitigation/Restoration, and Management Strategy Performance (Astm Special Technical Publication, 1442.)

This new publication reviews recent advances in contaminated sediments-management-related research and focuses on the engineering aspects of contaminant transport, erosion, stability, monitoring, and modeling. It identifies both established and innovative physico-chemical and biological tests and methods used to characterize and evaluate properties and behavior of contaminated sediments, as well as the potential for contaminant transfer. This data reflects recent work carried out on large coastal investigations and on natural and artificial capping of contaminated sediments. Twenty-three peer-reviewed papers cover: Sediment Characterization of contaminated sediments has become more and more complex. It involves ex situ techniques from standard tests (e.g., physical properties) to biological analysis in addition to all the chemical analyses, but also in situ ones like erodability tests. Mitigation and Restoration Methods are diversified and touch on many different environments from river sediments and harbor lagoons to land reclamation. They involve techniques ranging from the use of geotextiles and geocomposites to selective sequential extraction methods Monitoring and Performance aspects of contaminated sediments are largely supported by extensive site investigations, like the Southern California project, but also by the development of modeling tools. In addition, four peer-reviewed papers in this volume summarize a five-year research effort aimed at evaluating the performance of a catastrophic capping layer resulting from the major 1996 Saguenay flood disaster that proved to be very beneficial to the Saguenay Fjord environment and ecosystem by covering most of the ancient contaminated sediments. Audience: This book is an invaluable resource for environmental engineers and scientists, water quality engineers, soil scientists, geotechnical engineers, and environmentalists, educators, and legislators.
