EPA Claim Fracking Caused Wy. Water Contamination
Note also the following from the Rig Zone Article linked above:
“The latest test results came from two wells that EPA itself constructed, and which reached to depths of about 775 and 970 feet, deeper than other private water wells in the area. It detected levels of benzene, a carcinogen, that exceeded safe drinking water standards as well as synthetic chemicals—glycols and alcohols—used in hydraulic fracturing fluid.”
They didn’t find those chemicals in people’s water wells. They dug extra deep wells below where people were getting their water and found chemicals at the lower depths, not a health hazaard at the drinking water depth.

This field is rather unique in that decades ago, they actually did hydraulic fracturing IN the drinking water Aquifer rather than thousands of feet below it.
“The agency also stressed that the findings are unique to Pavillion, where fracturing has taken place both in and below the drinking water aquifer and very close to drinking water wells conditions that are not common elsewhere in the U.S. The region has been home to oil and gas drilling since the 1950s, and some of the 169 gas production wells in the area were fractured at points just 1,220 feet below the ground.
By contrast, in South Texas, energy companies are extracting natural gas from the Eagle Ford shale formation at depths ranging from 4,000 to 14,000 feet below the surface.”
