: "Or consider the case of Tony Oppegard and Jack Spadaro, members of a team of federal geodesic engineers selected to investigate the collapse of barriers that held back a coal slurry pond in Kentucky containing toxic wastes from mountaintop strip-mining. The 300-million-gallon spill was the largest in American history and, according to the EPA, the greatest environmental catastrophe in the history of the Eastern United States. Black lava-like toxic sludge containing sixty poisonous chemicals choked and sterilized up to 100 miles of rivers and creeks and poisoned the drinking water in seventeen communities. Unlike in other slurry disasters, no one died, but hundreds of residents were sickened by contact with contaminated water.

The investigation had broad implications for the viability of mountaintop mining, which involves literally lopping off mountaintops to get access to the underlying coal. It is a process beloved by coal barons because it practically dispenses with the need for human labor and thus increases industry profits. Spadaro, the nation's leading expert on slurry spills, recalls, 'We were geotechnical engineers determined to find the truth. We simply wanted to get to the heart of the matter "
