LINCOLN-

Carlin C. Coppin Elementary school in Lincoln is closed this week after black mold was discovered in at least one classroom.

“One of the problems is we had condensation in some of the (air conditioning) units inside the buildings, and that is the cause of the water, which is the cause of the mold, is what we’re thinking at this time,” Western Placer Unified School District Superintendent Scott Leaman said.

Coppin was built in 1973, and periodically tested for black mold. Over this past summer, work had been done on a set of classrooms where the fungus was detected.

“We’re very confident it is construction related,” Leaman said. “We did some extensive testing in 2010 at this school, and it was found to be clear.”

Parents are happy the school was closed, at least through the weekend, to take care of the mold.

“Black mold is serious, you know? It’s good that they are concerned about the kids,” parent Blake Tingy said. “They shut everything down right away and got going.”

Tingy and his wife have three kids that attend Coppin, one of whom is in the class where the mold was found.

“It’s kind of a concern, especially with the allergies my daughter has,” Tingy said. “Hopefully, they can at least nip it in the bud.”

Tingy’s biggest concern is figuring out weekday childcare.

“My wife is working from home today. I’ve kind of taken it slow, working local. We kind of just have to plan as we go,” he told FOX40.

Leaman appreciates parents’ patience while crews eradicate the problem.

All 400 Coppin students are expected to be able to return as early as Monday.
