BISMARCK — An estimated 9,240 gallons of produced water spilled Sunday, Oct. 3, at a saltwater disposal facility in Williams 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 Oasis Petroleum reported the spill about five miles southeast of Williston occurred due to an equipment failure, though the cause of the spill is still under investigation. About 85 gallons of brine is estimated to have run off into a nearby agricultural field.
Department officials will continue inspecting the site and monitoring remediation efforts, according to the release.
