Chromiamium-6

Here's a list that makes Miami seem less crappy to live in then, say, Pittsburgh.

It's, of course, not surprising that Pittsburgh would be pretty high up on the cancer-chemicals-in-your-water list (and I would guess that it varies pretty significantly depending on where exactly the water was sourced from). Generally speaking, I would guess that Pittsburgh is pretty high up on most gonna-poison-you lists. I'm not sure if it's still the case, but I'm pretty sure the ol' hometown at least used to be host to the largest number of Superfund sites in the country.

(And just because it wasn't detected at all in Indianapolis, doesn't mean anyone needs to move there.)
