Officials say water-quality test results suggest that untreated sewage that spilled at Denver International Airport last week never flowed off airport property.
Officials first feared that up to 1 million gallons spilled but later said about 330,000 gallons overflowed a manhole after a pump-station malfunction. Airport officials say employees didn't
notice a backup alarm.
The sewage entered Third Creek, which leads to other waterways that flow toward Barr Lake, but officials said Monday that the sewage didn't go that far.
Monte Deatrich of the Tri-County Health Department said Monday that tests for fecal coliform showed a level less than what would be allowed at a swimming beach.
