The Physicians for Responsible Medicine (www.PSR.org) have complied scientific studies related to the impacts of fracking. The conclusion is that the technology as done today nation wide, has inherent deleterious health and environmental impacts.
There is no such thing as safe fracking!!! From health impacts, to contamination of drinking water, methane gas pollution, geological agitation, increased earthquakes, the compendium PSR has created should be used by every State and County fighting to place a complete moratorium on all fractured rock gas extraction.
