AUDUBON (AP) — Officials say a power outage in western Iowa's Audubon caused about 200,000 gallons of partially treated wastewater to spill into a nearby creek.
The Iowa Department of Natural Resources says Audubon lost power around 5:30 p.m. Sunday, and a backup generator at the wastewater treatment plant failed to start as a result.
Power was restored about 10 p.m. Sunday, but wastewater continued to discharge to Bluegrass Creek south of Audubon until Monday morning, when an electrician repaired the generator.
The DNR says it's monitoring the situation and investigating to determine why the backup generator didn't work. The agency has advised that those in the area stay away from the creek for the next two days.
