Just a month after the chemical spill into the rivers of West Virginia, a lot of coal(more than 100,000 gallons) poured into a stream. Much of the stream turned black, and there were even traces of the coal in the Kanawha River. The spill occurred as a result of a malfunctioning valve. The coal spilled was coal slurry which is a waste fluid produced by washing coal with water and chemicals prior to shipping the coal to market. It contains a variety of substances that are likely more toxic than heavy metals, like iron, manganese, aluminum and selenium. Not only did the Patriot Coal valve fail, the alarm system also failed as the spill began to occur between 2:30 and 5:30 AM however it wasn't reported until 7:40 AM.
