Reviews how coal fires occur, how they can be detected by airborne and remote surveys, and, most importantly, the impact coal-fire emissions may have on the environment and human health, especially mercury, carbon dioxide, carbon monoxide, and methane.
Field trip to Powder River Basin coalbed methane (CBM) development areas showing impacts related to drilling, facilities, pipeline networks, access roads, withdrawal, and disposal of co-produced water from CBM wells.
