ENOLA, Pa. (WHTM) – Nearly 400 people gathered at a community meeting in Enola to discuss the mold concern at schools in the East Pennsboro School District.

Kelsey Ellis says she has more questions than concerns during Wednesday night’s meeting.

“I have faith in the fact that the school district is not going to put our children in harms way,” said Ellis. “I think they could have taken better preventative measures.”

Superintendent , Doctor Jay Burkhart shut down all schools on Wednesday. He says precautions are being taken, and they believe the problem started with recent high humidity and pipes sweating into the insulation around them.

Burkhart says that mold level is going down at the high school and they expect air quality results from the other schools by the end of the week.

He says it could take up to 30 days to get the pipes cleaned and wrapped with new insulation.

“You can’t do that kind of work in a few days.” said Burkhart. “While replacement is taking place, the air conditioning in the school will remain off.”

All four schools will remain closed on Thursday. The district says the high school will likely remain shut down through Monday.

Officials are advising parents to visit their family physician if their children are experiencing any symptoms consistent with mold exposure, and they should visit the district website for updates.
