Firefighters had to deal with frigid conditions while battling a massive blaze in Blue Grass.
Five departments responded to the fire at Rich Metals. Crews were able to overcome the cold and put out the flames but fire officials say the building is a total loss. Now they're worried the water they were spraying onto the engulfed building may have mixed with hazardous oils and liquids and washed into a nearby creek.
The Iowa Department of Natural Resources says it has an environmental specialist checking into that.
"They placed the boom on the down-graded side to where the water would have run off before it entered the crick and then they placed it in locations along the crick," IDNR's Terry Jones said. "We're going to walk the crick and assess the damages that we see and see where we're at with that and they'll continue their clean up efforts on that end."
Firefighters say they don't know what caused the fire yet. As a precautionary measure the nearby elementary school was evacuated to a local church for the day.
