Sub Base Superfund Site Cleanup Nears Completion
December 8, 2014
TheDay.com: After 24 years as a federal Superfund site, the Naval Submarine Base [in Groton, CT] is about 2 years away from completing cleanup of contaminated areas of the 576-acre site and just marked another milestone in the multimillion-dollar effort.
On Monday [Dec. 1], the Environmental Protection Agency informed the sub base that it has accepted its report on completion of the remediation and restoration of a 19.6-acre wetland at the north end of the base. The wetland, contaminated with DDT bricks placed there in the 1960s—as well as PCBs, petroleum residues and heavy metals from dredged soils dumped there—is one of the largest of about 2 dozen areas on the base identified by the EPA for cleanup when it placed the site on the list of the nation’s most polluted properties.
