Concepts and Technologies for Bioremediation in Confined Disposal Facilities
Abstract
The Dredging Operations and Environmental Research (DOER) Program is leverag- ing with U.S. Army Corps of Engineers (USACE) Districts and the U.S. Environmental Protection Agency to develop low-cost bioremediation technologies for contaminated dredged material in confined disposal facilities (CDFs). This research is aimed at transforming CDFs, diked structures designed to retain dredged material solids (Headquarters, USACE, 1987), from disposal to treatment facilities. Benefits will include operation of CDFs as reclamation facilities, conversion of contaminated dredged material to a soil-like material for beneficial use, and recovery of CDF storage capacity, thereby avoiding the costs of new CDFs. This technical note has two purposes: to assist USACE District staff in their application of bioremediation techniques to organic contaminants in CDFs, and to identify research needed to better understand and optimize contaminant biodegradation in CDFs. Design concepts and bioremediation technologies that show promise for practical application to recalcitrant organic contaminants in dredged material are described. The technologies reviewed include composting, landfarming, and land treatment. Information provided includes description of technologies, applicability, limitations, costs, and the science on which bioremediation technologies are based.
