American Thinker: New Study Settles the Science on Fracking & Proves It is Safe

Is a new study enough to definitively declare fracking safe?
From American Thinker:
The science is settled, as the climate change supporters like to say.  Only this time, science confirms the safety of hydraulic fracturing.  According to a new study published by the National Academy of Sciences, fracking is safe.  End of discussion. 
Funded by the National Science Foundation and Duke University, a team of scientists at Ohio State and other universities conducted extensive research into the purported link between groundwater pollution and fracking.  (The full title of the report, available online, is “Noble Gases Identify the Mechanisms of Fugitive Gas Contamination in Drinking-Water Wells Overlying the Marcellus and Barnett Shales.”)  In an examination of 130 wells, the researchers found that, when properly conducted, no groundwater or aquifer pollution resulted from the practice of fracking itself. 
Among the 130 wells studied, the researchers found only a subset of cases, including seven in Pennsylvania and one in Texas, in which faulty well construction or cementing was to blame for the seepage of gases into groundwater.  According to Professor Avner Bengosh of Duke University, “[t]hese results appear to rule out the migration of methane up into drinking water aquifers from depth because of horizontal drilling or hydraulic fracturing.”  That is to say, in the rare cases where it occurs, gases are entering the water supply from outside the borehead as a result of faulty well construction or poor cementing, both of which are manageable problems.
