West Virginia is facing another chemical spill, but this time it's coal slurry.

On Tuesday, coal slurry from a line in the Patriot Coal facilities spilled into Fields Creek -- a tributary of the Kanawha River near Charleston.



The slurry blackened six miles of the creek and inspectors are testing water to determine how much leaked, CNN reports. They believe roughly 100,000 gallons spilled.
