Coal and Water Pollution Union of Concerned Scientists

Mining operations can negatively impact water supplies, often with longlasting effects. The fundamental issue involves contamination of nearby rivers, lakes, and aquifers by what comes out of a coal mine—usually highly acidic water containing heavy metals like arsenic, copper, and lead. The process is known as acid mine drainage.It happens when certain substances (typically iron sulfide

What is coal gasifiion? HowStuffWorks

The U.S. Department of Energy explains that coal gasifiion is a thermochemical process in which the gasifier's heat and pressure break down coal into its chemical constituents. The resulting "syngas" is comprised primarily of carbon monoxide and hydrogen, and occasionally other gaseous compounds.
