A study published in May 2011 in the peer-reviewed Proceedings of the National Academy of Sciences found a link between methane in drinking water supplies and proximity to shale gas drilling. Seven months later, the EPA said for the first time that chemicals used in fracking had been found in drinking water in Pavillion, Wyo., home to hundreds of natural gas wells. And in July 2012, the U.S. EPA said its tests of wells around Dimock, Penn., had revealed barium, arsenic, or manganese at levels high enough to present health concerns in the water supplies of five households.
