The North Dakota Department of Environmental Quality (NDDEQ) has been notified of a source water spill resulting from a pipeline leak in Bowman County. The pipeline is operated by Denbury Onshore, LLC.
The incident occurred about 10 miles south of Marmarth on Oct. 23, and it was reported the same day. The cause of the pipeline leak is currently unknown.
Source water is used for enhanced oil recovery. It is higher in dissolved solids and minerals than fresh water; however, it is much lower in salt than produced water.
Initial estimates indicate approximately 10 barrels of source water were released from the pipeline, impacting Hay Creek. The creek discharges into the Little Missouri River approximately 2 miles downstream of the release point. No impacts have been detected in the Little Missouri River.
Personnel from the NDDEQ are inspecting the site and will continue to monitor the investigation and remediation.
