Bradford Island Contaminated Sediment Removal
November , 2009
After the equipment was removed, a survey was performed to identify areas were the PCB concentration was above allowable limits. In 2007, a proposal was put out by USCOE to remove this PCB contaminated sediment.
We supplied the floating platforms on which the filtration system was assembled, and conducted all maneuvering and handling of the platforms. We also provide all the diving services required to perform the removal of the PCB-contaminated sediment.
Working in sediment that contained high levels of PCBs required the implementation of contaminated-diving procedures. Divers wore vulcanized rubber dive suits with special neck seals that are integral to the dive hat, and connected boots and sealed gloves which totally isolate the diver from the surrounding water. When the diver surfaced, tenders wore rain suits and face shields to protect themselves from contaminated sediment that may have attached itself to the diver’s suit.
