Boston Globe 4/12/09: Many anglers unaware Lake Cochituate fish are unsafe to eat. As the Army readies plans to clean up polluted sediment on the bottom of Lake Cochituate, Marco Kaltofen of Natick worries about the anglers who bring catches tainted with dangerous PCBs home to their families. The lake’s bottom is contaminated with PCBs, or polychlorinated biphenyls, that were released during the mid-1980s from the Army’s Natick Soldiers Systems Center, long known as the Natick Labs. The Army suspects the source was a transformer explosion at its research facility on South Pond, the southernmost portion of the lake. Fish take in the PCBs and people – especially children and pregnant women – who eat the fish can face serious health problems.
