EPA Results Show Contaminated Water in Wyoming Fracking Zone

Residents told not to drink from contaminated wells

By Stacy Feldman

Government scientists have found that private water walls in Pavillion, Wyo. are polluted with toxic chemicals used in the controversial gas drilling technique of hydraulic fracturing, or fracking — and residents have been told not to drink from them.

The findings offer the latest evidence that the fast-spreading gas-extraction method could be endangering public health.

The U.S. (EPA) found methane from natural gas in seven of 19 wells that were tested in January of this year. Eleven had 2-butoexythanol phosphate, a common solvent in fracking fluids that experts say can cause kidney failure, toxicity to the spleen, liver cancer and fertility problems.

They also found traces of benzene, a cancer-causer, and other chemicals that come from crude in 17 of the wells, with "high levels" detected in groundwater that is connected to the drinking water aquifer.

At a public meeting Tuesday night, attended by around 100 residents, well owners were told by the to use alternative sources of water for drinking and cooking. 

Apparently, it wasn't news to many in attendance.

"For a lot of us it just confirmed what we already knew," said John Fenton of s, an organization formed to combat gas contamination.

Most important was the discovery that the methane detected in seven of eight water wells is coming from the natural gas reservoir and not bacterial action, Fenton told SolveClimate News.

"It shows there's communication between the natural gas production zone and the drinking water zones," he said.

A spokesman for ., the primary gas driller in the area, said the methane is “likely naturally occurring.”

"If it were coming from our production wells, much higher levels of methane would be seen," Doug Hock told SolveClimate News.

Second Round of Results 

The results from the tiny ranching town could be crucial in the national debate over the safety of fracking, currently exempt from federal regulation.

The process injects millions of gallons of water, sand and undisclosed chemicals at high pressure into horizontal wells to force open dense and deep shale rock and release natural gas.

This is the that EPA has tested water near gas wells that have been fracked in the central Wyoming community.

The first samples were taken last March and May, after Pavillion residents complained of foul smelling water and an increase in heath problems, including nausea, vision problems and fatigue, as well as rare cancers, seizures and liver disease.

The results showed that 11 of 39 wells were contaminated; three were filled with fracking-related 2-butoxyethanol phosphate. The EPA said further study was needed.

The town has 80 domestic wells and eight groundwater wells.

The latest report, issued late Tuesday night, said it has not reached conclusions as to the source of the contamination.

Richard Mylott, a public affairs specialist for EPA in the region, said its "investigation is ongoing."

"We will continue to collect and analyze groundwater samples to see what they tell us about potential sources," Mylott told SolveClimate News.

Hock said his company inherited the problem from a previous driller.

testing for well water

Hi, anyone have any ideas of where to get your well water tested for these type of chemicals coming from gas wells??
