The federal government has returned to a Pennsylvania village that became a flashpoint in the national debate over fracking to investigate ongoing complaints about the quality of the drinking water.
Government scientists are collecting water and air samples this week from about 25 homes in Dimock, a tiny crossroads about 150 miles north of Philadelphia.
“Take a skunk and every household chemical, put it in a blender, puree it for five minutes and take a whiff,” said Dimock resident Ray Kemble, 61, describing the smell of his well water. “It burns the back of your throat, makes you gag, makes you want to puke.”
He said investigators from the Agency for Toxic Substances and Disease Registry, a federal public health agency, were at his house Monday to collect samples.
Fracking is a method that uses huge amounts of pressurized water, along with sand and chemicals, to extract oil and natural gas from rock formations deep underground.
Dimock was the scene of the most highly publicized case of methane contamination to emerge from the early days of Pennsylvania’s natural gas-drilling boom. State regulators blamed faulty gas wells drilled by Cabot Oil & Gas Corp. for leaking combustible methane into Dimock’s groundwater.
Cabot, one of the largest natural gas producers in the state, has consistently denied responsibility, saying methane was an issue in the groundwater long before it began drilling.
“Numerous sets of data collected over the past several years in Dimock, by both EPA and DEP, have confirmed there is no threat to human health and the environment,” said company spokesman George Stark, referring to federal and state environmental agencies.
The Agency for Toxic Substances and Disease Registry said Thursday it is testing the water for bacteria, gases and chemicals. The agency is also testing indoor air for radon. Sampling results are expected in the fall, which will be shared with residents. A report will be released to the public next year.
“Residents have continued to raise concerns about natural gas activities impacting their private water well quality,” the agency said in a statement to The Associated Press. It said the investigation will “determine if there are drinking water quality issues that may continue to pose a health threat.”
It’s the first time ATSDR itself has tested private well water in Dimock. The Environmental Protection Agency conducted testing in 2012. ATSDR analyzed those samples and found explosive levels of methane in…
