Pipeline spill affects pastureland in western North Dakota

BISMARCK, N.D. (AP) — State environmental officials say a spill of produced water and oil has affected pastureland in western North Dakota.

The North Dakota Department of Environmental Quality said Tuesday it was notified of the pipeline leak in McKenzie County. The pipeline is operated by Henry Hill Oil Services LLC.

The spill happened about 4 miles (6.4 kilometers) west of Watford City on Friday and was reported the next day. The cause of the pipeline leak is unknown.

Produced water is a mixture of saltwater and oil that can contain drilling chemicals. It’s a byproduct of oil and gas development.

An initial estimate indicates about 8,400 gallons of produced water were released from the pipeline, affecting pastureland. State inspectors are checking the site and will continue to monitor the investigation and remediation.
