LIVERMORE FALLS — Air quality test results done on four rooms in the Livermore Falls Middle School basement show that any concern over elevated mold counts has been abated, district Maintenance and Transportation Director Ken Vining said Monday.

Results on two of the basement classrooms where the mold concerns originally arose, had previously come back abated after thorough cleaning and students were moved back in, he said.

The remaining two classrooms that were cleaned passed tests Monday and the rooms have been OK’d to go back into use, he said.

The upstairs rooms tested “typical” and the testing company recommended continuing normal daily cleaning. When the district buys new vacuums, it will buy ones with high-efficiency particulate air filters, Vining said.

Superintendent Judith Harvey ordered air quality testing to be done on the basement classrooms in early October due to water-related issues over a period of seven months.

The tests revealed, according to Principal Ted Finn’s Oct. 21 letter to parents, that the mold levels were of “moderate concern.”

Factors included a water leak into a basement classroom and a very, wet summer, that never had a chance to dry up,Vining said.

The most affected rooms were the science rooms, which are partially below ground level, he said.

They’re looking into a dehumidifier system to keep the rooms dry and prevent any recurrence of mold elevation, he said.

Regional School Unit 36, which has schools in Livermore and Livermore Falls, hired Air Quality Management of Gray to do the testing and ServePro of Lewiston to do the cleaning, he said.
