There was a question last night at the Long Term Recovery Meeting... About the Duke University Test Results on Water and Ash at the TVA Disaster site: Well... here is you answer...

and the link.....

A report by Duke University scientists who analyzed water and ash samples from last month’s coal sludge spill in eastern Tennessee concludes that “exposure to radium- and arsenic-containing particulates in the ash could have severe health implications” in the affected areas.

"Duke research scientist Gary Dwyer analyzed the water samples for trace metal content using inductively coupled plasma mass spectrometry. Following preliminary analysis, the solid ash samples were incubated and underwent more detailed analysis of their radioactive content using gamma spectrometry.

The Duke researchers received no funding from the group or any other external party. All funding was provided by the [Duke University] Nicholas School, Vengosh said, “to maintain total impartiality in our analysis.”
