(NAFB.com) – The North Dakota Department of Environmental Quality is advising the public to avoid a 2-mile stretch of the Cannonball River in Hettinger County after a chemical spill Wednesday. The spill, which included 200 gallons of diluted herbicides and approximately 15 gallons of diesel, occurred Wednesday morning when a tractor and sprayer fell into the Cannonball River roughly a mile west of New England in southwest North Dakota.  He got too close to the bank, and the bank gave way. The driver was not injured. said Bill Suess, manager of the Department of Environmental Quality’s spill investigation program. Suess said he does not expect any long-term negative impacts from the spill. Approximately 15 gallons of diesel also spilled, causing a light sheen on the water. We should have that cleared up already today, Suess said Thursday. The river is not a source of drinking water, nor is there any risk of downstream effects.
