Fracking may have caused the contamination, but it's by no means certain. And when did the EPA turn into a welfare agency? Oh, never mind. I answered that one myself.
Welfare agency? This sounds a lot like the modus operandi of the Superfund system which fixes alleged problems then goes and sues the alleged offender for the cost. Which situation Rats would have been drooling to have go down at a fracking site. They will probably kill this contractor or make him say uncle with court costs even if the case evidence itself is dubious. Every fracker from coast to coast would be wise to get behind this guy.
