The EPA is as crooked at the FDA and USDA. Fracking should be an issue left to the community that it effects. Some communties will welcome it because it brings jobs, others will close their doors because of possible side effects. Longmont, Colorado is a good example of this. The people of Longmont were given the choice of whether or not to allow fracking through a vote, and fracking lost. Rightly or wrongly I can not say, but it was a choice that was given to the people, not the government or the gas/oil companies, so Id say it was a success.
And hey, look what it says: "Several different hydrocarbon gasses, including methane, ethane, propane, and several higher molecular weight compounds, were detected in the groundwater-quality samples." And a separate statement from them: "Oil and gas development and production operations at the surface and below ground can affect water quality." Only took me 5 minutes to find.
USGS statement to NY: [link] If it's too hard for you to read, it was awfully nice of them to have underlined sections. Oh, look what's in the 3rd paragraph: "Methane contamination of domestic water wells has occurred near selected shale-gas development sites in north-central Pennsylvania (Osborn and others, 2011)"
Either way, every state is different. What Just because a well in Arkansas doesn't show contamination doesn't mean a well in Wyoming or Pennsylvaia won't and vice versa.
YO DAWG WE HEARD YOU LIKE NATURAL GAS SO WE PUT NATURAL GAS IN YOUR WATER SO YOU CAN BURN WHILE YOU DRINK
I'm not totally opposed, but right now there's too little information, the technology hasn't caught up enough, and asking the companies to be responsible is like asking the banks to stop fucking up the economy again and again.
Well, I guess let's hope the EPA takes a second look at their studies then.
I rather doubt that Fracking is innocent of problems... there are things that go on which are pretty bad. On the other hand, I know the rumors can also be unrealistically exaggerated, like they are in Gasland.
