DENVER (AP) -- The seep of liquid hydrocarbons in a western Colorado gas field has affected a larger area than initially believed.
A month ago energy workers discovered contaminated soil and groundwater near the Williams gas processing facility in Parachute. Officials on Monday said that natural gas liquids have now been found on both sides of Parachute Creek, which runs into the Colorado River.
Officials insist the creek remains untainted.
Protective booms were placed across the creek when the hydrocarbons were first discovered. A state Department of Natural Resources spokesman said early tests on those booms revealed "diesel-range organics" but not the benzene or gas liquids that have been found in the soil and groundwater.
It's not clear if the diesel materials are related to the leak.
