People would freak out over the possibility of oil getting into the Great Lakes like it did the Gulf, but natural gas seems virtually harmless.
I happen to be a Directional Drilling Engineer working in the Marcellus Shale Region. Any drilling under the Great Lakes will be done from land with no possibility of a disaster like the one in the Gulf. On top of that, there is no way in hell that fracking can fracture the upper strata levels and cause gas or oil to migrate to the surface. It all occurres at 9 to 10 thousand feed deep, is highly contained and the fractures are less than 50 feet around the Well bore, with hundreds of non permeable formation layers above it, to protect the upper levels.
There are also strict safety standard in place that are closely monitored by State and Federal agencies to insure that these safeguards are in place, documented and tested.
The ignorance and stupidity I am reading from some of these morons who make these ridiculously uneducated claims, makes me furious. Even more so, they are the ones the public believes the most!
