In Wyoming (elevation circa 5000 feet) some ground water could be thousands of feet below the surface. But the oil would still be thousands of feet below that.
But the EPA is still lying. That is what they do.
I wonder why getting accessible oil out the ground never presented that ground water problem to the degree that it all had to be banned?
By my definition, if subterranean water is “thousands of feet” below the surface, it is not “ground water.”
I can dream up a situation in which any improperly completed oil or gas well pollutes fresh ground water. Fracking has been around at least 50 years.
Obama’s hysteria is driven by politics (as if people on this forum didn’t know that! LOL).

Around the coal fields in Eastern Wyoming, the NG is mixed with shallow ground water. Doubt they have to frac, only go down to the coal seam and pump out water and gas.
