Tennessee coal ash spill contains high levels of toxic heavy metals

According to some just-released test results, the coal ash at the Harriman sludge spill contains high levels of toxic heavy metals, some up to 300 times the legal limit:

According to the tests, arsenic levels from the Kingston power plant intake canal tested at close to 300 times the allowable amounts in drinking water, while a sample from two miles downstream still revealed arsenic at approximately 30 times the allowed limits. Lead was present at between twice to 21 times the legal drinking water limits, and thallium levels tested at three to four times the allowable amounts.

All water samples were found to contain elevated levels of arsenic, barium, cadmium, chromium, lead, mercury, nickel and thallium. The samples were taken from the immediate area of the coal waste spill, in front of the Kingston Fossil plant intake canal just downstream from the spill site, and at a power line crossing two miles downstream from the spill.

This comes via the Appalachian Voices blog, a great source of breaking info and pictures from the spill. Full release beneath the fold:

Who will be the next victims?

A couple weeks ago an earthen damn holding back billions of gallons of coal sludge broke and let loose a torrent of toxic filth.

 

Wonder how long this one is going to hold.

Au revoir, 2008

Well, here we are on the last day of 2008. I feel like I should do some kind of valedictory post, a look back over the year, or predictions for next year, or some kind of list, or ... something. Everybody else is.

But I got nothin'. It's funny, at the end of a year when the world seemed to get faster and crazier -- the epic drama of the election, shriller and shriller warnings from scientists about global warming, the biggest economic crash in a half-century -- I find myself preoccupied with with the small-scale and domestic. My strongest memories of this year will mostly be of moments laughing around the dinner table; my three year old's passionate-if-incoherent stories about the adventures of the "Minium Falcon"; my five year old's first attempts to sound out written words; reading the Narnia books at night, my older boy's head on my shoulder, the little one blinking hazily against sleep.

Thank goodness for the bubble of joy and calm I've got up here in North Seattle. 'Cause it's been an intense year, and next year -- nay, the next decade -- is shaping up to be a white-knuckle roller coaster ride. I'll jump back on it next week, but for now, I'm enjoying the quiet.

Peace and, as always, many thanks to all Grist's readers for their support, knowledge, passion, and participation.

Global warming increasing rainfall and intense storms

Hope you've all got umbrellas:

The frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif.
