My apologies for seeming so hateful and aggressive towards the gas industry and making this seem like a craigslist rants and raves ad, but what I am saying has everything to do with the O.P. The man wanted to know the pros and cons of hydrofracking and those are some that I have first hand personally seen. As for the overall safety, like many have said there is a lot of propaganda and no one can seem to give a straight answer, greenies hate it, gassers love it, all depends on which side of the fence you're on and how much your pockets have been lined. I personally can say I live in the area and have witnessed first hand the boom, it'll come and go and then what will be left behind? Take an educated look at the BIG picture and not just the money, water is the key to life, and I have been to town meetings where some farmer brought in his personal water after the drilling and asked the man from the gas company preaching about how safe fracing is to drink that water and he wouldn't. I haven't been wronged in any way by big gas and please don't misconstrue me as some gas hating greenie, I have worked construction my whole life and do know people involved in the gas field and they are not all bad people. Just be an informed citizen, go to meetings, talk to everyone, read the newspaper, watch the news and make your own decision, just remember, Hitler had a nation of people believing that the Jewish people were the cause of all of their problems, what I mean is, don't believe everything you hear, just whole heartedly think about everything involved from the roads, to the land, the towns, the economy, the families. Do the positives outweigh the negatives?
