Dr. Benitez Question and Answer Session on Fly Ash Spill

How did you decide which elements to test for in the medical screening process?

There was a long list of chemicals that basically EPA, Department of Health, etc., have been testing. We first looked at the list to see of those different chemicals or elements out there, which ones are a potential human risk. Based on that, we then looked at - based on what’s there and has some potential for human risk- how can we really assess them, measure them, and look at them. And therefore, then, we could narrow the list even further. And then the next question was, what is the best way to measure that particular chemical, because sometimes you can actually measure the chemical, but sometimes the best evaluation’s not to measure it, but to measure the effects on a particular organ or system, so this is an ‘indirect measurement,’ if you will.
