To be honest, I had never heard of fracking, before I stumbled on it in the 60 minutes story.
Fracking is a process of getting at Natural gas reserves deep underground:
Of course Dick Cheney, ex Halliburton honcho, when VP under Bush jr, created a genre of drilling that would be totally exempt from all environmental protections.
Fracking requires huge amounts of water, and the process just happens for foul the waters when leaks occur & the fractured zones happen to leak into drinking water aquifers, ponds, lakes & waterways.
Toxic Chemicals contaminate drinking water, making it unsafe. This toxic water can actually ignite, has killed massive farm animals & resulted in massive fish kills.
Leave it to Dick Cheney to come up with one of the most vile, life-blood-sucking, environmentally horrific loopholes to foul up the nation's drinking water. There has to be a special place in hell for Cheney.
