Superintendent Elaine Miller spoke to TV5 on Wednesday confirming that these cleaning companies will remain on site until further notice.
Miller says air quality test results came back within an acceptable level, however there is room for improvement.
The school has hired an industrial hygenist who has made suggestions on how to improve the building’s air quality as construction work continues on the school’s major renovation project.
Miller also says six air exchange systems have been placed in construction areas to filter out dust and circulate fresh air into work areas.
The air quality tests were ordered after parents and students complained to administration, citing health concerns due to the construction.
