PARACHUTE, Colo. (AP) - Crews are working to contain and clean up an underground oil spill that has contaminated at least 846 barrels of groundwater in western Colorado.
The state Department of Natural Resources said Monday that 57 barrels of natural gas liquids had been recovered as of Sunday morning, the latest update available. The spill covers a 200-by-170 foot area and is located about 60 feet from Parachute Creek.
Officials say there are no signs the creek has been affected. Containment booms have been placed around the creek and crews are checking the water every half hour.
The leak was discovered March 8 but the cause isn't known.
The Denver Post (http://bit.ly/11b1ACl ) reported that Williams Energy told state regulators that "hydroexcavation work was being done" in a pipeline corridor when crews found discolored soil.
