A broken pipe connection caused a brine spill on Saturday that contaminated farmland in Mountrail County, according to information released by the North Dakota Department of Health on Tuesday.
Basic Energy Services estimates that 500 barrels, or 21,000 gallons, of produced water spilled at a saltwater disposal well owned by Basic Energy Services about 7 miles southeast of Tioga.
The company estimates that about 50 barrels, or 2,100 gallons, of brine got off the well location and onto cropland, said Bill Suess, spill investigation program manager for the Department of Health. Produced water is a waste byproduct of oil production.
Health department staff have inspected the site and will continue to monitor the investigation and cleanup.
