Impact Assessment of In-Place Contaminated Sediments on Water Quality: A Concept,

Abstract

In the past, environmental assessments of US Army Engineer 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. The 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 Civil Works operations and maintenance navigation projects for assessing the environmental consequences of in-place contaminated sediments. The approach and the potential benefits are delineated.
