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.​
Industrial and municipal point-source discharges and nonpoint source pollution from agricultural and urban areas over many years have contaminated bottom sediments in the rivers, harbors, and nearshore areas of the Great Lakes. Improved controls for discharges have reduced pollutant loads to the Great Lakes. However, toxic substances in bottom sediments continue to impair sediment and water quality and may contribute to toxic effects in aquatic biota and, potentially, in humans. Areas in the Great Lakes that remain seriously impaired have been designated as "areas of concern" (AOCs) under the Great Lakes Water Quality Agreement (U.S. Environmental Protection Agency (USEPA) 1988). Public support for control of pollution in these AOCs has prompted increased attention by Government agencies and environmental organizations toward development of plans for remediation.
In this text, drawn from presentations and discussion at a May 2005 NATO Advanced Research Workshop, current approaches to the assessment and remediation of contaminated sediments are discussed with emphasis on in-situ management. The text addresses physical, chemical and biological approaches for the assessment and remediation of sediments. The development of regulatory and strategic approaches is discussed with emphasis on the potential for biological remediation in the management of contaminated sediments.
The Great Lakes National Program Office (GLNPO) of the U.S. Environmental Protection Agency (USEPA) has established the Assessment and Remediation of Contaminated Sediments (ARCS) Program in response to the Water Quality Act of 1987. The ARCS Program was charged with assessing and demonstrating remedial options for contaminated sediment problems in the Great Lakes. A set of technologies was identified, through a literature survey, for laboratory and field testing with sediment samples collected from five Great Lakes Areas of concern. Laboratory tests were conducted using nine processes, and pilot-scale (field-based) demonstrations of bioremediation, sediment washing, solvent extraction, and low-temperature thermal desorption were conducted at five sites. Analyses were performed on feed materials and all process residues showing polychlorinated biphenyl (PCB), polynuclear aromatic hydrocarbon (PAH), and heavy metals removal efficiencies ranging from > 6% to 99%. This paper presents the results of the five pilot-scale demonstrations conducted by the ARCS Program.
