Pennsylvania Wells Found to Have Fracking Chemicals
Drinking water sampled from wells in Pennsylvania has tested positive for 2-Butoxyethanol, a chemical used in Marcellus Shale fracking operations. While the substance, thought to be a carcinogen, is used in products such as paint and cosmetics, the authors of the paper reporting these findings describe a plausible mechanism for the chemical originating from fracking. As one of the authors, and geoscientist, Susan Brantley put it, “This is the first case published with a complete story showing organic compounds attributed to shale gas development found in a homeowner’s well.” The New York Times has the story: http://www.nytimes.com/2015/05/05/science/earth/fracking-chemicals-detected-in-pennsylvania-drinking-water.html?smid=tw-nytimes&_r=1 

Pennsylvania Pipeline Threatens Streams and Fish
In another story concerning Marcellus Shale fracking in Pennsylvania, the proposed construction of a natural gas pipeline in the state is said to pose a threat to streams and wildlife. The disruption caused by such construction projects is well known to generate sedimentation in adjacent waterways. This can spell disaster for creatures living in affected streams. It doesn’t help that in 2005 oil and gas companies were exempted from federal government permit requirements to control erosion.
