When Containment Walls Fail  

Pharyngula has some great video of a containment wall in Tennessee failing, releasing a vast flood of toxic coal sludge - Let's talk about clean coal.

When power plants burn coal to produce energy, the coal doesn't just vanish into the atmosphere to cause global warming. No, there's a substantial amount of left-over sludge called coal ash, a nasty mess that is enriched for toxic heavy metals. It is seriously nasty stuff. This glop has to be stored, somewhere, usually piled up and walled-off, because it's not healthy for anything.

Behold what happens when the containment walls fail.

This is happening right now, here in the United States. Yesterday, a retaining wall failed, and 500 million gallons of coal ash — the vile grey slime in the video — poured down into the tributaries of the Tennessee River, the water supply for Chattannooga and environs.

We're looking at a major environmental catastrophe, bigger than any oil spill, and most of the news media are silent about it. I checked CNN, MS-NBC, even Fox News…not a word. The local newspapers have a few articles, and the regional blogs are trying to follow it, but otherwise, I guess we're going to pretend it didn't happen.
