A northeast Iowa school has suspended classes due to a mold problem. Officials at River Hills School in Cedar Falls announced Thursday that due to a malfunction in a pneumatic controller in the cooling system, the school has some mold growth in the building.

As a result, River Hills School officials have decided to suspend school beginning today, while commercial cleanup and air testing are conducted. School officials say they hope to resume classes at River Hills in a couple of day. The missed school days will have to be made up.
