Description:Additional testing has revealed several more areas at Wethersfield High School with elevated PCBs, but no air or surface contamination.
The test results show there is no danger to human health, said Lawrence J. Cannon, president of EnviroMed Services Inc., which did the testing.
"I think it's very good news," Cannon said. "You're in a situation where you have material that may be buried, but we're finding no public health risk at all."(1:19)
