PCBs are located in the hallways, library, offices at the St. Johnsbury School

PCBs are located in the hallways, library, offices, kitchen, a stairwell and a 6th-grade classroom at the St. Johnsbury School. But the levels are low enough that the school doesn’t need to take any action. “The testing focused on the original portion of the building constructed back in 1948 as the trades school,” said Superintendent Karen Conroy. “PCBs are more likely to be found in schools built or renovated before 1980. The PCB testing occurred on Aug. 14 by an environmental consultant who collected samples of indoor air that a laboratory processed. The results were then reviewed by the Vermont Department of Environmental Conservation and the Vermont Department of Health.
