There is an alternative to using water for fracking and that is using liquid petroleum gas. This is a fairly new method developed by a company in Canada. I am not saying I am for it either and it seemed a little counter productive at first but the process does make sense at least from an economic stand point. The LPG returns to the surface and can be re-pressurized and used again. This method eliminates the waste water flow back and the disposal issue. I also feel that there needs to be more research done with this method so we can put regulations in place. Here is a news article about LPG and the use of it in Ohio.

I agree we really need regulations in place for fracking, but neither side the companies or the groups against it are really willing to sit down and discuss all of the issues related to it.

This "fracking-earthquake" red herring is keeping all of us from dealing with those pro actively. I wish the public and the industry could have a legitimate discussion of these and that standardized laws and rules could be adopted nationally which insure public safety.
