State environmental scientist Bill Suess said regulators were notified Monday of the 8,400 gallon pipeline leak in Renville County. The pipeline is operated by Wichita Falls, Texas-based Cobra Oil and Gas.
Suess said the spill of produced water happened 2 miles north of Sherwood, and within a 1 mile of the U.S.-Canada border. The cause of the pipeline leak is unknown.

Produced water is a mixture of saltwater and oil that can contain drilling chemicals. It's a byproduct of oil and gas development.
Suess said about 1,000 square feet of cropland was affected. He said no water sources were harmed.
