See, what happens is, the companies who are doing the fracking drilling won't do it the way it should ideally be done, but if they would do it the way it should be done, there wouldn't be groundwater contamination! And as my mother used to say, if pigs had wings, they could fly.

In any event, we should all feel a lot better now, knowing that the reason the water is being contaminated is completely different - if related:

The hydraulic fracturing of shale formations to develop natural gas has no direct connection to groundwater contamination, according to a study released Feb. 16 by the Energy Institute at the University of Texas at Austin .

The study reported that many problems blamed on hydraulic fracturing are related to processes common to all oil and gas drilling operations, such as casing failures or poor cement jobs.

University researchers also concluded that many reports of contamination can be traced to above-ground spills or other mishandling of wastewater produced from shale gas drilling, rather than from hydraulic fracturing, Charles “Chip” Groat, an Energy Institute associate director, said in a statement.

“These problems are not unique to hydraulic fracturing,” he said.
