BISMARCK, N.D. (AP) — Nearly 41,000 gallons of oilfield wastewater has spilled from a broken pipeline in western North Dakota, impacting an unknown amount of land.
The North Dakota Department of Environmental quality says Kansas-based Tallgrass Energy reported the produced water spill on Monday near Watford City. It was not immediately known what caused the leak.
Agency officials were on scene Wednesday. A regulator says the wastewater migrated at least a half-mile break in the pipeline.
Some of the water spilled in a dry drainage ditch that connects to Spring Creek, a tributary to the Little Missouri River.
