Pipeline problem identified
EnCana Oil & Gas (USA) has determined that about 13,700 gallons of produced water were spilled Tuesday as a result of a pipeline problem near Rifle.
About 1,386 gallons made it into Mamm Creek a half mile away from the spill on Garfield County Road 336, said Doug Hock, a company spokesman.
EnCana determined that the spill was caused by overpressurization of a recently repaired section of the pipe. EnCana has sampled the creek and found no evidence of elevated pollutants, Hock has said.
He said that’s probably a result of dilution and the fact that the water had undergone some treatment for removal of hydrocarbons. EnCana recycles water used in well fracturing, transporting it by pipeline to reduce truck traffic.
