Train carrying 'potential contaminants' derails into the Yellowstone River

A train carrying "potential contaminants" derailed on Saturday into the Yellowstone River located in Montana. 

The train was going over a bridge that collapsed, resulting in the derailment. As of now the officials are unsure of what started the incident, according to ABC News.

Three of the derailed cars were carrying hot asphalt and molten sulfur, the director of Emergency Management for Yellowstone County, KC Williams, told the news outlet. 

Williams said the drinking water has not been contaminated as of now. 

Officials in Montana have warned the public to stay away from parts of the Yellowstone River due to "potential contaminants."

The sheriff's office told ABC News that this poses no immediate threat to Yellowstone County.
