Impact Assessment of In-Place Contaminated Sediments on Water Quality: An Approach,

Abstract

In the past, environmental assessments of Corps of Engineers (CE) Civil Works water resource projects that involve dredging of contaminated sediments have addressed only the consequences of dredged material disposal. The environmental benefits that may be incurred from the removal of in-place contaminated sediments have not been considered. This deficiency in evaluating the environmental consequence of sediment removal has been due to the lack of a logical delineated approach to quantifying the impacts of contaminated sediments on water quality as well as the reluctance of regulatory agencies to consider contaminated sediment removal as a benefit. This paper presents a conceptual approach developed for the operations and maintenance Federal navigation projects for assessing the environmental consequences of in-place contaminated sediments. The approach, along with potential benefits, is delineated.
