Subject: [CPEO-MEF] SEDIMENT: Groton Naval Submarine Base (CT) drredging
Projects dredge up toxic past at sub base

Waterfront cleaned up for use by Virginia class

Groton - Like power-washing layers of grime off a rooftop in a sooty industrial city, the dredging projects under way this winter at the Naval Submarine Base are scooping away the silt and mess from the near-shore river bottom after decades of military use, and unwitting abuse.

The two projects, begun last month, span a large area of the Thames River waterfront at the base and will render it more usable for today's Virginia-class subs, as well as tugs and other equipment. In all, the two projects will cost about $14 million and are removing 185,000 cubic yards of river bottom sediment - some of it so highly contaminated it will have to be trucked to a toxic-waste landfill out of state.

The smaller of the two projects, in the area known as the lower base, is the more complex, because it involves the highly polluted soils. One day last month, as a giant claw-like shovel attached to a crane pulled load after load of inky black muck from the dark depths, Richard Conant, environmental program manager, described the work. The claw was attached to a crane operated by one of the project contractors, Mohawk Northeast.
