Media outlets and industry figures often refer to Jackson's testimony during a May 2011 Senate Hearing Committee that she is not aware of any cases where hydraulic fracturing itself has contaminated water.[1] A 1987 EPA report and reports released since May 2011, however, have identified hydraulic fracturing as the likely source of water contamination in several cases.[2][3][4][5][6][7][1][2]

federal environmental regulators have made a direct link between the controversial drilling practice known as hydraulic fracturing and groundwater contamination...The EPA found high concentrations of benzene, xylene, gasoline and diesel fuel in shallow groundwater supplies that they linked to wastewater pits. But the report also found a number of fracking chemicals in much deeper fresh water wells.
