EPA has yet to demonstrate any evidence of hydraulic fracturing linked to groundwater contamination. EPA’s work at Pavillion, Wyo., joins Parker County, Texas and Dimock, Penn., as examples of unsound science leading to unsupported conclusions. Technical reports released by the United States Geological Survey (USGS) showed that USGS groundwater sampling results contradicted EPA’s results and that the EPA monitoring wells created for the testing were unsuitable for groundwater quality assessment.
Hydraulic fracturing makes it possible to produce oil and natural gas in places where conventional technologies are ineffective. It uses water pressure, under tight controls, to create fractures in rock that allow the oil and natural gas it contains to escape and flow out of a well. Hydraulic fracturing is well-regulated and safe, and it has a proven track record.
A significant body of both government and private research, including DOI’s own research finalized since the original May 2012 proposed rule for hydraulic fracturing on public lands, continues to show that there are no documented cases of hydraulic fracturing contaminating groundwater, from the Marcellus Shale to California.
