State and company officials say contamination levels have dropped along waterways affected by a massive saltwater spill in western North Dakota’s oil patch.
A pipeline leak detected last month spilled nearly 3 million gallons of saltwater brine near Williston. The wastewater is a byproduct of intensive oil drilling taking place in the Bakken region of North Dakota and Montana.
North Dakota Department of Health official Dave Glatt said Tuesday that elevated chloride levels initially detected along the Missouri River and the Big Muddy River are returning to normal levels.
Pipeline owner Summit Midstream Partners LLC said Tuesday that it was making “significant progress” in the cleanup. But the Texas-based company offered no timeline for when the work may be done.
Some previous saltwater spills have taken years to clean up.
