| A mold problem has re-occurred at Calhoun Middle-High School, according to Donnie Pitts, facilities administrator.
Pitts said most of the mold was discovered in the middle school section of the building, which had essentially been shut down in later summer.
Special crews are scrubbing and cleaning the mold in all classrooms using bleach as a disinfectant.
"We are not using the custodians of the building, but have hired individuals to take step-by-step action," Pitts said.
"Somewhere between 50%-75% of the building has some level of a mold problem," said Pitts.
The problem is related to issues with the functioning of the heating and air conditioning system in the building, a problem that surfaced ten years year.
Pitts said the cleaning and daily operation of the HAC system will not present a problem for the health of students and occupants of the building.
A mold problem surfaced at the school in 2002, which required significant efforts to abate the problem.
In 2005, former superintendent Ron Blankenship said the county had received $60,000 to improve Calhoun Middle-High School's heating and cooling ventilation system, which has caused problems since the school was built.
The system has caused the formation of mold in parts of the school, which has been fought on a yearly basis. Similar systems in other new schools around the state have also experienced the same problem, Blankenship told the Herald at the time.
