Evaluating PCB Transport from Contaminated Sediments During In Situ Capping

Contaminated sediments represent a major pollution problem in the   U.S. and abroad. Currently, 15 to 2  percent of National Priority   List (Superfund) sites and 42 of the 43 Great Lakes Areas of Concern   (AOCs) contain underwater sediment beds with hazardous organic   and/or inorganic contaminants. The costs associated with this   problem are significant, with recent EPA estimates for clean-up of   the Great Lakes AOCs alone estimated to be in the billions of   dollars. Of the various strategies available to remediate   contaminated sediments, in situ management exhibits significant   promise due to the potential large cost savings, minimization of   further water contamination, and little sediment disturbance. The   placement of an in situ cap over a contaminated sediment deposit to   trap fine-grained particles and associated contaminants is a   relatively simple procedure that induces complex changes within the   underlying sediment. These changes are poorly understood and need   further study for this procedure to be confidently used.    (toxic organic); (toxic organics); (PCB); (PCB's); (PCBs);   (polychlorinated biphenyls); (polychlorinated biphenyl); (chemicals   of concern); (chemical of concern); (sediment); (sediments)
