WILLISTON, N.D. — A North Dakota health official says a 70,000-barrel brine spill near Williston that has affected two creeks is the largest since the state’s oil boom began.
Dave Glatt with the state Department of Health’s environmental health section says operator Summit Midstream has begun the cleanup process and inspectors have been monitoring the affected area.
Brine is an unwanted byproduct of oil production and is considered an environmental hazard. It’s saltier than sea water.
The saltwater was released from a pipe Jan. 7 about 15 miles north of Williston and reached nearby waters in Blacktail Creek and Little Muddy Creek.
Glatt says a contractor has pumped out from Blacktail Creek about 64,000 barrels of a mix of water and brine.
A Summit Midstream representative didn’t immediately return a call seeking comment.
