Hi there everyone,
Here is a gchat interview I had with Dr. Dan Bain. He’s a geology professor here at the University of Pittsburgh who spoke at a conference on Shale Drilling put on by the University of Pittsburgh’s school of Public Health. Here you are. Enjoy.
Dan: Hi Maegan
me: Hi Dr. Bain. Thanks for chatting with me today. Before we start, I just wanted to let you know that at least part of this conversation will appear on our blog; so I just wanted to give you a heads up on that and to make sure that’s ok with you.
Dan: I understand that this chat may be included on your blog and am fine with that
me: ok great. So I actually saw that this past Friday was the conference on Shale drilling run by the school of public health. I heard that you were one of the speakers and I was wondering if you could maybe just give a brief summary of what you spoke on?
Dan: Sure, my presentation was mostly on my best guesses of unintended consequences of shale gas extraction. Particularly in SW PA, we have littered the landscape with contamination from coal extraction and steel production. Much of this contamination is said to be “naturally attenuated.” That is, it has been sequestered by natural processes. However, the salinity that is produced by shale gas extraction is not something our systems are accustomed to. In laboratory systems such a change in water chemistry can mobilize materials from the sediment.
The question is, how does it behave in environmental systems? And that is hard to say. But I do think we have to consider it as we continue gas extraction.
me: I see. So you’re basically saying that because the environmental impacts of shale drilling are unknown, it is something we must be cautious about?
Dan: As with any human action.
But this system is particularly worrisome in that the rate of activity is increasing at an accelerating rate.
History shows that this characteristic, common in resource extraction economies, often leads to environmental messes without responsible parties to “clean up”
Aka a “boom and bust” cycle
me: I think it’s very interesting to know that you’ve looked into how resource abstraction has occurred throughout history. Could you give us an example of an instance when this “boom and bust” has happened in the past?
(Dr. Bain later e-mailed me this link in answer to the prior question.Here’s an interesting story from Wyoming.)

me: Do you think there are any safer methods of unconventional gas drilling?
Dan: I do not know of any
me: Another question I thought I would ask is more directed to the general public. There may be people who follow our blog that have been approached by gas companies for leases on their land but are wondering what to do. What kind of advice would you give someone in that situation?
Dan: Test your water several times before signing anything. Ask your neighbors what the conditions of their lease are and ask for more to get at least as much. In fact, check the lease conditions on PA state land and ask for better conditions than those. Be informed and don’t be afraid to walk away. If you have gas, they will come back..
me: interesting…I think that will be very helpful for people to hear. Thanks for your input, Dr. Bain. I believe we’ve reached the end of our interview so I won’t take up any more of your time. I really appreciate your contribution to our blog and I think people will be very interested in reading what you had to say during our g-chat. Thanks again and have a great Thanksgiving break!
Dan: Thanks for your patience. I hope your Thanksgiving is fun too.
If you have any follow up, feel free to please send me an email.
me: Oh great thanks again and I appreciate your willingness and availability Take care and have a good night.
Dan: good night.
