BISMARCK, N.D. (AP) — Officials say an abandoned disposal well at the Lignite Gas Plant has leaked produced water in northwestern North Dakota.
The North Dakota Department of Environmental Quality says the spill happened about a mile east of Lignite on Nov. 24 and was reported that day.
The gas plant is operated by Steel Reef, LLC. The volume that was released was not known when the spill was reported. But Steel Reef now estimates that about 83,160 gallons of produced water were released, affecting agricultural land.
Produced water is a byproduct of oil and gas development. It is a mixture of saltwater and oil that can contain drilling chemicals.
State inspectors are checking the site and will monitor the investigation and remediation.
