scientists battle it out over whether fracking is contaminating groundwater

EDIT: For an excellent primer on shale gas, fracking and both pros & cons, check this out:

I wanted to point this out not only because the subject matter is appropriate for this blog, but an example of how evidence is presented and debated and through additional studies, conclusions and consensus are reached.  I imagine within the next year, there will be a consensus on this issue.  I’m a little torn on the press release the authors made, and that this was attacked in one of the responses.  Seems out of place.

Basically, the authors argue that the isotope signatures of the carbon in methane in water samples matches the carbon of methane being extracted from nearby wells, and other scientists have issues with sample size and conclusions without considering other sources of methane in the region.

So the original article is here:

some objections are raised here and here, and the rebuttal:
