Details/Description

This workshop provides attendees with management and remediation solutions to contaminants in both marine and freshwater sediments including the effects of remediation on the benthic environment. All aspects of contaminated sediments will be reviewed, including determination of contaminant sources, site characterization, remedial technology selection, monitoring, and demonstration of the effectiveness of remedial technology. Participants will come away from this course with the skills and knowledge to assess and remediate contaminated sediments with a scientifically valid and legally defensible plan at minimum cost. Attendees will learn about both conventional and emerging technologies for remediating contaminated sediments. Technologies presented will be: removal followed by treatment and disposal; in situ isolation of the sediments from the environment by covering the sediment with neutral materials (i.e., passive capping); active capping technologies that employ chemically active sequestering agents, and monitored natural recovery, which involves monitoring processes that isolate, degrade, transform, and immobilize sediment contaminants under natural conditions. These emerging technologies that address contaminant toxicity, biogeochemistry, and transport mechanisms offer much promise and will enhance the attendee’s ability to effectively manage sediments at a reduced cost and improved effectiveness over conventional methods.
