When Barbara Bremsner picks up her son from South Whidbey Intermediate School in Langley, she can tell something isn’t right.

“It’s a very helpless feeling,” said Bremsner. “He has headaches all the time. He is fatigued all the time.”

Bremsner blames it on black mold. It’s been growing in the back of her son’s classroom.

“We found a couple of small patches that were six inches by two inches that have black mold on them," a school official said.

Black mold is caused by severe water damage and can cause cold or flu symptoms as well as other health problems.

Room 201 has since been sealed off and vacated.

School officials say the mold doesn’t pose any serious risk. The room is sealed and the mold isn’t airborne. But school leaders said they’ll be testing the adjacent rooms just in case.

Still, at least two students and one teacher have reported getting symptoms, Bremsner’s son included.

Bremsner says the district needs to do more.

“I think all the kids need to be removed and put in a safe environment,” said Bremsner.

District officials will begin repairing the moldy classroom Tuesday afternoon. Repairs should take two weeks.
