From The Pueblo Chieftain (Chris Woodka):
A spill of 10,000 gallons from a sanitary sewer lift station at Fort Carson, including small amounts of petroleum, was reported to the Environmental Protection Agency on June 7, according to information provided by the Colorado Water Quality Control Division…
The spill occurred at a pre-treatment plant meant to separate oil from water before water is routed through a sewer plant. The EPA is evaluating corrective actions and steps that must be taken to prevent future overflows, said David Gwisdalla, environmental engineer with the EPA. The cause of the spill was an extreme rain that caused a manhole to overfill, sending 10,000 gallons of untreated sewage into a ditch leading into Fountain Creek, according to the report.
