EnCana spills produced water near Rifle

RIFLE, Colorado ” An EnCana Oil and Gas (USA) waterline rupture caused an unknown amount of produced water to flow into Mamm Creek near Rifle, the company announced Tuesday.

The malfunction occurred early Tuesday about five miles south of the Colorado River near County Road 336, said Doug Hock, a spokesman for the company. He said the produced water traveled about a half mile before it entered the creek.

“We are still working to determine the volume of the spill,” he said.

Initial sampling of the released water conducted at points along a five mile distance from Mamm Creek to where it flows into the Colorado River by EnCana revealed no elevated concentrations of pollutants, Hock said. That may be due to the fact that water had gone through treatment for removal of hydrocarbons before it was placed in the line for eventual use in the company’s drilling operations, he said.

Hock said the Colorado Oil and Gas Conservation Commission, the Colorado Department of Public Health and Environment, along with the county and municipalities downstream of Mamm Creek, have all been notified of the release.

EnCana is currently investigating the cause of the line rupture, Hock said.

EnCana transports produced water by pipeline to reduce the amount of truck traffic for its well drilling and completion operations, according to the company.

Produced water comes up with natural gas from deep underground and contains hydrocarbons ” crude petroleum ” and dissolved solids including salts that in most instances could not be used for irrigation, to water livestock or for domestic use. Across the state, water produced by oil and gas drilling is either recycled or injected into deep wells.
