NC State released results from the second phase of testing for PCB compounds in Poe Hall on Monday afternoon, which showed that concentrations of Aroclor-1262 to were twice the amount that was present in samples from testing done in December, but still below EPA exposure levels for school indoor air environments. Material samples were able to determine the likely source of the Aroclor-1262, pointing to an insulation sealant used in the supply ducts. “While relatively high concentrations of Aroclor-1262 PCBs were found in certain materials inside the HVAC ductwork, the testing data show us that PCB concentrations in the air do not exceed applicable EPA risk-based thresholds,” Chancellor Randy Woodson wrote in a message to the University.
