The "fracking panic" is just that, a manufactured eco-nut non-event. There is ONE documented case of an improperly-cemented well casing leading to contamination of an underground aquifer by flowback of fracking fluid. Just one. In Wyoming. All the rest of the complaints I'm aware of have been duly investigated by state and federal authorities and it's been concluded that any methane contamination of aquifers is coming from NATURAL sources, and are unrelated to the drilling.
So long as the well casing is properly cemented, the fracking fluid, which is injected thousands or tens of thousands of feet below shallow aquifers, cannot move up on the outside of the casing, and whatever is produced from the well as a part of opening the bore for use is supposed to be disposed of properly.
Gas companies have no interest in contaminating aquifers because they can be held financially liable for doing so, and if it happens, it means that the multi-million dollar hole in the ground they just finished drilling is useless because the casing was improperly cemented and the gas they hope to bring up is now going somewhere else instead. It would be fiscal idiocy not to pay attention to cementing the well properly, and few and far between are the instances of a gas or oil company screwing up the procedure, particularly on surface wells.
The Deepwater Horizon accident in the Gulf was caused by improper cementing, but that was taking place thousands of feet underwater, and they certainly did not intend it not to work properly, and it's cost them billions to fix the problem.
All the rest is just horseshit concocted by know-nothings who are scrambling for yet another reason to impede domestic oil and gas production.
Yes, fracking fluid is pumped back to the surface into pits, but EPA regulations outlawed the abandonment or backfilling of pits years ago, and now the fluid must be pumped into trucks and taken to a licensed disposal location, and the pits (which are now lined by law) and liners must be cleaned up.
Accidents happen, but drilling companies have to pay for such accidents, so they work very, very hard to avoid them.
