Fracking isn't bad for you?
The New York Times reports a study (recently published in the prestigious 'Proceedings of the National Academy of Sciences'), claiming that hydraulic fracturing or 'fracking' is not per se a cause of contaminated water. Instead, contamination is said to arise from leaks in the wells used to recover the gas, which has been liberated by the fracking process.

Of course the Times scrupulously avoids any countervailing opinion. They do nonetheless include some comments by Scott Anderson, of the Environmental Defense Fund, to the effect that many steps could be taken to avoid leaky wells.
My sense here (as a scientist and engineer with over 50 publications in peer reviewed journals) is that we are not getting the full story. Would anyone care to further enlighten me (and other readers at this site) ?
