Monday night, 2.6 million cubic yards (the equivalent of 525 million gallons, 48 times more than the Exxon Valdez spill by volume) of coal ash sludge broke through a dike of a holding pond in Tennessee.
Until I saw this video, I had no idea of the scope.
Apart from the immediate physical damage, the issue is what toxic substances are in that sludge: Mercury, arsenic, lead, beryllium, cadmium. This toxic sludge got into the Emory River, a tributary of the Clinch and Tennessee Rivers: The water supply for Chattanooga, Tennessee as well as millions of people living downstream in Alabama, Tennessee and Kentucky.
Needless to say, the authorities need to get to the bottom of what went wrong and hold the responsible parties accountable.
This sort of thing really makes the proposition of clean coal so absurd. Even if you can scrub all the CO2 out of it, you still have so many other toxic waste products associated with burning coal that have to be stored that carbon emissions are just a part of the problem.
