All classrooms in the South Butler School District were open Friday as districtwide testing for mold, which was found in a classroom, was conducted.

Superintendent David Foley, who posted an update on the mold situation on the district website, said the results of the tests on the air samples collected from 48 sites throughout the district should be known by next week.

“They collected them (Friday). Because there are a large number, they expect the results to be back by the middle of next week,” Foley said.

Intertek PSI of Pittsburgh's proposal to conduct the testing is attached to Foley's update. It outlines how the company will look for mold, water leaks, dampness, moisture and staining and take air and swab samples in each school building.

That testing will cost $5,330 and additional testing would cost more, according to the proposal. The company will prepare a mold remediation plan if necessary for $1,200.

“As soon as we get the results I'll follow up with a letter to the district. However those results come back, we'll decide what to do next,” Foley said.

Mold was discovered last week in some throw rugs and in a classroom. Air tests found 5,800 spores per square meter in the classroom. The maximum acceptable level is 2,000.

That classroom was closed Wednesday, the first day of classes, and Thursday while the room was cleaned and dehumidifiers were set up. Those efforts worked as the air was deemed safe and the classroom was back in use Friday.

“People have been very supporting and happy that we are doing the best we can to investigate and determine that our buildings are safe for our students and staff,” Foley said.
