fracking contaminates water, true or just a lefty concern?

what's up with the water contamination propaganda on fracking. Is that legit or the usual tree-hugging response to any sort of oil exploration type work?

If not properly done, sure it contaminates water. Just like the mess BP got into in the Gulf by taking short cuts.

If the well is not properly drilled, cased and cemented, then there is a small potential for groundwater to become contaminated. However, it is unlikley as the gas will most likely rise to the ground surface and NOT go into groundwater aquifers. The gas will want to rise upwards to where the pressure is lowest - almost always the atmosphere at the surface. Why would it push/force its way into a underground aquifer when it could more easily float upwards??

It's not the gas we worry about, it is the fracking chemicals and the by products of chemical reactions with the geologic formation and native fluids.

From the experts I have heard from, the actual fracking process where it relases the gas has not been known to continue up into aquifers, but the even without drilling we do get Radon gas at the surface that comes from the shale gas deposits. Fracking it can't help. The contamination we see to the water almost always comes from the associated activity at the surface. Well caseings do fail over time which could be a problem in years to come even after the well has been capped. Eventually all the fracking fluid and toxic chemicals from the earth will be dilluted into our environment. it will get into the food chain and damage life, including humans.
