Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal Power Impacts | Union of Concerned Scientists

Coal impacts: water pollution. When you burn charcoal in your grill at home, ash is leftover. The same is true for coal-fired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.
