A pipeline leaked nearly 19,000 gallons of saltwater in northwest North Dakota, state officials said.
The pipeline owned by Continental Resources ruptured after it ended up struck by equipment excavating at the site about 16 miles north of Tioga.
The 450-barrel saltwater, or brine, spill ended up contained to the excavated area near the pipeline. The state department of Health said the spill did not have an impact on any waterways and is not a threat to public health at this time.
Brine is an unwanted byproduct of oil production and the state considers it an environmental hazard. It is many times saltier than sea water and can easily kill vegetation exposed to it.
The Department of Health and the North Dakota Oil and Gas Division have responded and say cleanup is underway.
