It was the second time Legionella has been detected in Oakwood schools in the past month. The bacteria was found at Smith Elementary School after tests in early August.
The bacteria can cause pneumonia-like Legionnaires’ disease. A Kettering Fairmont High School custodian died in 2019 of the disease.
Anytime a building or fixtures have been dormant or unused for a period of time, bacteria can build up, Public Health - Dayton & Montgomery County has said.
At Smith, “all of the water sources are currently operational and safe to use,” district spokeswoman Traci Hale said previously.
District officials said they worked Solid Blend Technologies, a water management business, to treat the Lane and Smith water systems.
Smith also was treated for the bacteria in August 2020.
