BISMARCK — An estimated 15,960 gallons of produced water and 3,200 gallons of oil spilled Friday, June 31, at a saltwater disposal well on the northwest edge of Dickinson, N.D., 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 Scout Energy Management reported that the spill occurred due to an overflow at the disposal well. The spill was contained to the site, and nearly all of the brine and oil has been recovered.

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