BISMARCK, N.D. (AP) — The North Dakota Oil and Gas Division reports a valve leak has spilled 105,000 gallons of treated produced water in northwestern North Dakota.

The release was reported Monday at Justin SWD 1 saltwater disposal well, about five miles (eight kilometers) southwest of Tioga.

Bosque Disposal System, LLC reported Tuesday that 2,500 barrels of treated produced water was released due to a valve/piping connection leak. The product was contained on-site and at the time of reporting all of the spill had been recovered.

A state inspector has been to the location and will monitor any additional cleanup required.

The produced water was mixed with hydrochloric acid which was neutralized with sodium bicarbonate as part of the cleanup. Hydrochloric acid is a commonly used acid in oil and gas production.
