LYMAN, S.C. (AP) -- More hazardous PCBs have been found at a sewage treatment facility in the Upstate.
The Herald-Journal of Spartanburg reports (http://bit.ly/189XKHU ) that three grease traps at Lyman's treatment plant recently tested positive for polychlorinated biphenyls, or PCBs.
The chemicals were used for decades in a variety of industrial applications. PCBs were banned in 1979 after tests showed they could cause ailments including cancer. They are now found when decades-old facilities are cleaned out or demolished.
State health officials have been investigating PCB dumping in the Upstate, where the hazardous chemicals have been found in a number of sewer treatment systems.
In September, the Department of Health and Environmental Control issued an emergency regulation aimed at reducing the spread of materials containing PCBs.
