WATFORD CITY, N.D. (NewsDakota.com) – Emergency crews were called out to an explosion at an oilfield saltwater disposal site southeast of Watford City Thursday.

McKenzie County Emergency Manager Karolin Jappe says there was only one man on site at the time of the explosion and he was not injured. The incident was reported just after 12 PM at a White Owl Energy Services site. The cause of the explosion and fire is unknown at this time.

Jappe says the fire will be allowed to burn out on its own. No structures or people are in danger. She says trying to put out the fire could cause the salt water to spread and contaminate the ground, which would be costly.
