Unconventional Natural Gas: Just a 'FRAC' Away

What about methane rising through the cracked rock and contaminating groundwater? That appears to be what happened in a few places already. I don't think enough is known about the long term problems of this hydraulic hydrofracking technology. Also, I believe that the author is wrong when he states that they only use sand and water. Typically shale formations require the addition of toxic chemicals to the frac slurry as the characteristics of shale are quite different than sandstone; one can not use just sand and water.
