A crude oil spill in eastern North Dakota from the Keystone pipeline has affected nearly ten times the amount of land as initially reported, according to the Associated Press.
North Dakota environmental scientist Bill Suess said the first report on Oct. 29 estimated that the leak affected about 22,500 square feet of land. The figure now stands at about 209,100 square feet.
Calgary, Alberta-based TC Energy (formerly known as TransCanada) estimated that the pipeline leaked about 383,000 gallons of oil and has recovered about 337,550 gallons as well as 141,834 gallons of oily water.
Although the cause of the spill is still unknown, a portion of the malfunctioning pipe has been sent to a third-party laboratory for inspection. TC Energy said the pipeline returned to service on Nov. 10 after approval of a repair and restart plan by the U.S. Pipeline and Hazardous Materials Safety Administration.
Some wetlands were affected, but not any sources of drinking water, according to Suess. The soil affected is currently being stockpiled and will be taken to a landfill in Sawyer, North Dakota.
