General Motors has been making progress with a polychlorinated biphenyls (PCB) clean-up effort at its powertrain plant in Bedford, Indiana. Ed Peterson and Cheryl Hiatt, the GM Managers working on the clean-up said that the last 6,000 tons of soil contaminated with PCBs will be removed from creek beds downstream of the Bedford plant by the end of summer.
The U.S. government banned the use of PCBs in the 1970s after studies showed PCBs were linked to health problems in humans. GM used PCB-containing hydraulic fluids in its equipment at the Bedford plant during the late 60s and early 70s. Since then, the chemicals are believed to have leaked onto plant property and then carried downstream into creeks. In 2001, the EPA, GM and Indiana environmental officials reached an agreement for clean-up of PCBs in Bedford, Indiana.
Peterson said the project could be finished in the window of 2013, 12 years after the agreement was made.
