4:27 The Burlington, Vermont school board decided this week to stop a multi-million dollar renovation project and not reopen the high school facility. Last year potentially cancer causing PCB’s were discovered in the buildings and grounds and the superintendent and school officials recommended the board now change course and build a new high school. In November 2018 city voters approved a $70 million bond to completely renovate the Burlington High School buildings. But last September air testing detected levels of PCBs above federal and state approved levels and the buildings were closed. Students attended classes remotely and are now attending in person classes in a converted department store in the city’s downtown.
