BISMARCK — An estimated 11,970 gallons of produced water spilled Thursday, Oct. 7, from a pipeline in Mountrail County, North Dakota, according to a news release from the state Department of Environmental Quality.

Produced water, or brine, is a mixture of saltwater, oil and sometimes drilling fluids that is created during oil and gas production.

Texas-based Goodnight Midstream reported the spill about seven miles northwest of New Town occurred due to a third-party contractor striking the pipeline. The company estimates that only about 1,260 gallons of brine was not immediately recovered.

Department officials will continue inspecting the site and monitoring remediation efforts, according to the release.
