>Hydraulic fracturing is not contaminating drinking water. These fractures are being created about 6,000 feet below the surface. That’s four Empire State Buildings stacked on top of each other between the aquifer and the hydraulic fracture. If anything is going to risk the integrity of the drinking water, point the figure at the construction of the well, the steel and concrete barrier that is built to isolate that aquifer from a flowing well.

Don't the companies doing the fracking usually build these barriers? How is it not their fault if they don't hold.
