Don't drink it! A Brita filter ain't gonna help this problem.
This is one of many disturbing scenes from the HBO documentary film GasLAND. Check it out. It explains everything you ever needed to know about the joys of natural gas drilling in this country. Whose doing it, where are they doing it, whose getting sick from it and who doesn't care who gets sick from it. I'm pretty sure you can answer that last question yourself. CORPORATIONS! Deny, Deny, Deny.
You don't have to be a tree hugging environmentalist to be concerned about this craziness.
