Marcellus shale well gas drilling threatens our waters

The drilling process results in loads of highly contaminated water. Where and how is it being disposed? How come resource extraction can't be done more safely?

Monongahela called one of most endangered rivers in U.S.
I grew up near this river in Green County, PA. We used to swim and boat in it. Our drinking water comes from it. I've seen the thick, dark pools of contaminated water that come up from the Marcellus shale gas wells and the tank trucks that carry this contaminant away. Where are the trucks going?
