Hydraulic-fracturing is poisoning ground water: Report
Methane levels 17 times higher near active fracking cites
Researchers at Duke University have analyzed methane levels in 68 drinking water samples collected across 5 counties in New York and Pennsylvania and found “evidence for methane contamination of drinking water associated with shale-gas extraction.”
The potentially harmful levels of methane gas were found in the samples near drilling sites, where natural gas is extracted from shale formation using a process called hydraulic-fracturing, or fracking.

“We found no evidence for contamination of drinking-water samples with deep saline brines or fracturing fluids,” researcher said. “We conclude that greater stewardship, data, and possibly regulation are needed to ensure the sustainable future of shale-gas extraction and to improve public confidence in its use.”

“But residents near drilling wells have complained fracking has polluted ground water supplies enough that they can light their drinking water on fire. In addition, accidents at wells have led to fires and floods of fracking fluids have reached streams.” Said a report.
“At least some of the homeowners who claim that their wells were contaminated by shale-gas extraction appear to be right,” said Robert Jackson, lead author of the study.
“It comes as no surprise that natural gas is not as clean as the industry pretends,” said an attorney with Earthjustice environmental group. “The gas industry has made it virtually impossible to do base-line testing because in order to do that, researchers need to know what they’re testing for – not just methane, but the variety of other contaminants being injected into the ground.”
One reason why poisons chemicals used in fracking were not detected/reported in the study samples might be because it would take “decades from now” for them to appear “as they work their way up from deeper levels,” a report said.
EPA scientists have already revealed that drinking water wells near natural gas [and oil] drilling operations contain chemical contaminants. They found dangerous chemicals in the water from 11 of 39 wells tested near the Wyoming town of Pavillion in March and May 2009. They admitted that the gas drilling was a potential source.
Researchers say these chemicals may cause cancer, kidney failure, anemia and low fertility problems, and pose serious health risks to people who live close to the drilling sites, a report said.
Currently 32 states are using fracking to release natural gas from shale formations, according to an Earthjustice.
The report was released by the National Academy of Sciences said on May 9.
Chesapeake Energy
In April, Chesapeake Energy suspended fracking in Pennsylvania after blowout spilled toxic fluid into river.
The Chesapeake well spewed thousands of gallons of toxic fracking fluid into a nearby waterway immediately after the blowout on Wednesday, said the Bradford County emergency management officials.
In March, Philadelphia officials asked the Delaware River Basin Commission on Thursday to stop prospectors using the hydraulic fracture shale gas extractions in the City’s watershed, until a full environmental impact assessment is conducted.

Philadelphia City Council
The City Council, in a unanimous resolution, has formally asked the Commission to stop all fracking operations in the watershed and deny a drilling permit to Stone Energy Corp, a Louisiana-based energy company prospecting for natural gas, and all others that propose to use fracking to extract shale gas in the Basin which supplies drinking water to more than 15 million people, including 2 million plus in the Philadelphia metro area.
Stone Energy
In march 2010, Stone Energy spokesperson, Tim O’Leary, reportedly said that fracking posed no danger to the drinking water in the region.
Truth and Financial Profits are Mutually Exclusive
FIRE-EARTH has always maintained that the energy companies cannot be telling the truth AND making a profit both at the same time!
Fire Earth has earlier noted that
In Dimock, Pennsylvania, drilling for natural gas has clouded the drinking water, sickened people and animals and made their wells flammable.
Now, for the first time ever, EPA scientists have revealed that drinking water wells near natural gas [and oil] drilling operations contain chemical contaminants. They found dangerous chemicals in the water from 11 of 39 wells tested near the Wyoming town of Pavillion in March and May 2009. Unfortunately, their report falls shy of concluding what causes the contamination, though it admits the gas drilling is a potential source.
Residents of Dimock, a small rural Pennsylvania town, have sued Cabot Oil & Gas Corp, claiming the company’s natural-gas drilling has contaminated their wells with deadly chemicals, causing sickness and reducing their property values
