Burn pits?

So, I'm scanning CNN.com and I come across the following headline:
So, of course, I assume it was something to do with deoderant and some bad chemical they put into it. And I thought, I know about that a little bit...maybe I can sue too.

Turns out, it was about burning garbage in pits on US Army bases. Now, I feel stupid. Stupid and embarrased.

And I still don't know what to do with my own burn pits.
