摘要

Although a cap can be placed and has been proven to be an effective control and isolation mechanism for contaminated sediments, concerns have been raised by regulating authorities as well as project proponents as to the effects any construction or maintenance activities will have on a cap. Various remedial projects near or under existing or proposed pier structures have had to address and manage environmental and structural issues pertaining to pile removal, pile installation, and construction. The predominant environmental concern with pile driving is that contaminated sediments will either be exposed or contaminants themselves will be mobilized through pore water advection/migration to the biologically active zone or overlying water column. This paper will review the technical issues associated with driving piles through an environmental remedial cap. A summary of the technical concerns and precedence that has been set for driving piling into a cap will be provided. This will include a discussion of any measurable impacts, standard ways of mitigating potential impacts, regulatory precedence and project examples.
