Fracking is not new. It has been around for 40 years. It's just being used with new horizontal drilling techniques.
Anytime there is the slightest water contamination, it has nothing to do with fracking.. You are getting waste water discharge and fracking confused. Fracking goes on 10's of thousands of feet away from any water tables and they are sealed and isolated by thousands of tons of concrete.
You don't know enough about the process to even speak intelligently.
