New report on Fracking and groundwater contamination

I work in geophysics, some of it oil and gas related, so I follow the fracking debate. Environmentalists oppose fracking. Movies and web sites devoted to the issue are widely available on the web and even streaming video services.  Strangely enough, the anti-fracking people are also supporters of efforts to limit CO2 production allegedly leading to global warming. They do this despite the fact that fracking has done more to reduce CO2 production than all the windmills and solar cells in North America. Because increasing the supply of natural gas, and lower its cost, gas is replacing coal as a source for electricity (incidentally, lowering your home heating bill).

Here's a new story about the environmentalists favorite study linking fracking to groundwater contamination.

Any natural gas in the ground water is the result of natural migration to the surface which occurred long before an fracking. This happens in lots of places, often to the delight of children that enjoy flames coming out of the ground.
