PCB dredging clean-up project begins on Lake Cochituate

摘要

A large ring of yellow buoys floats beside an Ellicott 300 SL 8" Swinging Drago dredge on the surface of Pegan Cove, marking the area where contractors have started removing sediment contaminated with PCBs, left by an accident at the Soldier Systems Centre 30 years ago.rnThe PCBs were found in the section of Lake Cochituate just to the east of Natick Labs. They came from a transformer explosion in 1 980 and got into the lake through a storm drain, said Jim Connolly, restoration programme manager for Natick Labs.
