Officials said benzene levels were too low to pose a short-term health risk but they warned the city's residents against drinking tap water out of precaution. Elevated levels of benzene were found in water samples taken from a treatment plant that serves about 6,000 people in the agricultural community of Glendive near the North Dakota border. The contamination followed a 50,000 gallon oil spill that found its way from a break in a Bridger Pipeline's 12-inch pipeline into the Yellowstone River. (AP Photo/Matthew Brown)

A company responsible for a Montana oil pipeline spill says the breach in the line has been located directly beneath the Yellowstone River.

Up to 50,000 gallons of crude were released in the .

Bridger Pipeline spokesman Bill Salvin said Tuesday a mechanical inspection of the damaged line revealed a about 50 feet from the river's south shore.

Salvin says bubbles were seen rising to the river's surface after nitrogen was pumped into the line as part of the inspection.

Officials previously didn't know whether the spill happened beneath the iced-over river or somewhere on the riverbank.

The cause remains undetermined.

The spill occurred Saturday about 5 miles upstream of Glendive. Residents are stocking up on after a cancer-causing oil component was detected in public water supplies.
