NORMANDY, MO (KTVI)-Missouri American Water hopes to cancel a precautionary boil advisory later Wednesday. It's still in effect for a large part of north, central and west St. Louis county.
Close to 85,000 customers are affected.
The boil advisory has caused the Normandy Schools Collaborative to cancel classes today. Rockwood schools are open with the district providing bottled water to students. Several stores in the affected communities sold out of bottled water.
Missouri American Water says a temporary power outage at their Chesterfield treatment plant led to the boil advisory. The water is safe for bathing or washing clothes, but people should boil tap water for three minutes before drinking it.
