New Study Supports Water Contamination Due to Fracking
U.S. Geological Survey Verifies EPA Findings in Pavillion, WY
PAVILLION, WY - An independent analysis of new U.S. Geological Survey (USGS) water monitoring data verifies a 2011 Environmental Protection Agency (EPA) investigation into whether hydraulic fracturing contaminated the Wind River aquifer near Pavillion, Wyoming - an important groundwater source that provides water to thousands of Wyoming residents and farmers.
The preliminary results of EPA’s study was one of the first to document hydrocarbons consistent with fracking fluid chemicals in drinking water wells and monitoring wells located near natural gas wells. EPA’s preliminary results have since been attacked by the oil and gas industry, as they seek to continue their dangerous practices and protect their own interests over public health and safety. USGS’s study was conducted specifically to check EPA’s results.
The Sierra Club, Earthworks, and the Natural Resources Defense Council worked with a hydrologist and independent expert, Dr. Tom Myers, to analyze the USGS raw data and compare those results with the original EPA report. Dr. Myers found that the USGS data support EPA's initial findings. EPA’s analysis should be widely accepted now that its findings have been replicated.
The USGS report found that thermogenic gas, which very likely comes from fracked deep shale formations, continues to increase in a monitoring well. This evidence strongly suggests that as a result of fracking, gas is seeping into Pavillion’s water. A range of chemicals associated with the fracking process also continue to appear in the monitoring well, showing that hazardous pollution is spreading towards the surface. This new information supports EPA’s hypothesis that natural gas drilling activities, including fracking, have contaminated the Wind River aquifer near Pavillion.

“The Sierra Club is concerned by the U.S. Geological Survey’s important conclusions, which further underline EPA’s report that fracking has contaminated Pavillion’s water,” said Deb Nardone, Sierra Club Beyond Natural Gas campaign director. “This report raises the alarm on the public health threats posed by dirty and dangerous fracking and the need to rein in a oil and gas industry that remains unchecked and unaccountable for their toxic pollution.”
“Dr. Myers’ analysis shows that the USGS upholds EPA’s preliminary conclusion that hydraulic fracturing contaminated Pavillion-area groundwater,” said Bruce Baizel, Earthworks’ Oil & Gas Accountability Project Senior Staff Attorney.” He continued, “It’s long past time for states and industry to stop denying oil and gas development’s environmental problems, and start working on fixing them.”
“This reinforces EPA’s findings – and the concerns of Americans in communities across the country – that dangerous fracking practices are putting our drinking water and health at risk,” said NRDC senior policy analyst Amy Mall. “That’s why it’s critical that EPA thoroughly investigate reports of fracking water contamination concerns. It’s essential that we protect Americans from a repeat of what we are seeing in Wyoming.”

The Sierra Club is the oldest and largest grassroots environmental organization in the United States. It was founded on May 28, 1892 in San Francisco, California by the well-known conservationist and preservationist John Muir, who became its first president. The Sierra Club has hundreds of thousands of members in chapters located throughout the US, and is affiliated with Sierra Club Canada.
