The Skeptic’s Guide to the Universe this week (episode #346) has an interview with Gordon Maupin, about fracking. I think Mr. Maupin was very reasonable and it’s definitely a good interview to hear for a calm, measured take on the topic.
It would have been nice to hear more discussion of the geological issues, but Mr. Maupin also isn’t a geologist so that’s likely why he wanted to address it mostly as a policy issue and just stick to move of an overview with where the science is at. (At the moment inconclusive with a large side of surface contamination being the more likely culprit.)
Hopefully once the EPA finishes their study, maybe they’ll interview a geologist…
