Fracking: What's In the Water?
Fracking, or hydraulic fracturing, has been largely unregulated. The New York Times reports that the EPA is taking a closer look at the practice:
The Environmental Protection Agency sent letters to nine drilling companies on Thursday requesting detailed information about the chemicals contained in fluids used to crack open underground rock formations in the hunt for oil and natural gas.Natural gas companies are buying up the rights to drill the Marcellus Shale in Pennsylvania and New York in a later day land rush, with a paucity of environmental oversight reminiscent of the bad old days of wildcat drilling. As far as I know, one company has agreed to list the chemicals used in fracking. The EPA is right to seek information on the chemicals mixed with the millions of gallons used in the practice.
