Think of it as another practice run for local and federal crisis management. The chemical spill into the Elk River that breached the containment walls of one of Charleston, W.Va’s largest industries last week has closed schools, stopped commercial flights and converted the state capitol’s downtown core to a “ghost town.” It’s also painted an unnervingly clear picture of what can happen to a city’s infrastructure when a chemical spill shuts down its main commercial facilities. After evidence of 4-Methylcyclohexane Methanol (MCHM), a foaming agent that is used to clean coal of impurities, was picked up by local water distribution plant West Virginia American Water last Thursday, state and county officials went into high drive to alert some 300,0000 residents of the pollution and to close access to drinking water.
