A hydrochloric acid spill may close a northwest suburban high school swimming pool for a while.
Firefighters responded to an alarm at Elk Grove High School, 500 W. Elk Grove Blvd, at 11:15 a.m. Sunday. A vapor cloud from the liquid hovered in the basement of the school's pool area where the pool's filtration system is kept, said Elk Grove Fire Department Lt. Mike Keenan.
Hazmat crews arrived to contain the leak and ventilate the building.
Keenan said about 30 gallons of the highly corrosive substance spilled.
An equipment failure is suspected for the leak, but the official cause is still under investigation.
It's unclear how much damage the spill caused.
