IMPLEMENTING EFFECTIVE REMEDIAL DREDGING PROJECTS

The choice of dredging as an environmental remedy should be based on several factors. These include site characteristics, contaminant distribution, accessibility, and analysis of short-term versus long-term risks. Dredging is particularly attractive for isolated "hot spots" and easily accessible, moderately contaminated sediments. For sites with poor accessibility and heavily contaminated sediments, a combination of contained hot spot dredging and placement of a postdredging sediment cap may be appropriate. Some sites are poor candidates for remedial dredging. When contaminated sediments exist close to bedrock or hard bottom, complete removal is rarely possible. Sites with highly contaminated sediments isolated in deep pockets also are less amenable to effective dredging. At sites where navigation is not a high priority and conditions do not favor dredging, other options such as natural recovery or in-situ capping of sediments should be evaluated.
