"However, samples of the fly ash scooped up along roadsides and river banks show elevated levels of arsenic that normally would trigger an EPA response, Sims said. "These are levels that we consider harmful to humans," he said. But the EPA is not responding because the TVA is taking action to fix the problem, he added.Arsenic is a natural element found in soil and minerals
, but exposure to it can cause sickness, the National Institutes of Health says."
I notice it says nothing about what the actual "elevated level" is, it looks like scare hype to me and it seems to be working. If it were so dangerous, where are the numbers? Arsenic is a heavy metal, one of many we come in contact with every day
Stockingfull, have a sample of your drinking water run through a competent labrotory. I'll bet you won't want to drink it after it gets a full analysis. And test the peanut butter for rat feces too while your at it.

The data I have seen indicates coal ash to be highly alkaline, with a pH range in the 10.0+ zone. The SO produces an acid, but that is in the flue gases and not present in the ash IIRC.
