According to the Daily Mail, at 10: 33 on May 10, 2011, a controversial gas production technology is polluting drinking water for thousands of families.
Scientists collected 68 samples of drinking water near gas drilling sites in Pennsylvania and New York.
They found that since methane is close to the hydraulic process, the methane content in the water may be harmful
Fracturing or fracturing.
The report released by the National Academy of Sciences said: "in the aquifer above the northern Marcellus and Utica shale formations --
We recorded systematic evidence of methane contamination in drinking water related to shale gas extraction in eastern Pennsylvania and northern New York.
"The fracturing method is to release natural gas trapped in shale formations by blasting a mixture of water, sand and chemicals into the Rock.
It has unlocked reserves that can supply the United States. S.
Although environmental activists say fracking can pollute water resources, in 100,
At 60 drinking water wells in the area, 51 were detected for methane concentrations, regardless of the operation of the natural gas industry, but the concentrations were much higher than those of natural wells
There are natural gas wells reported.
The average level of shallow wells in active drilling areas is 17 times higher than that in inactive drilling areas
Active areas, the report said.
The researchers concluded that "in order to ensure a sustainable future for shale gas exploitation and increase public confidence in shale gas use, more management, data and possible regulation are needed ".
Last week, President Barack Obama asked the U. S.
S. Department of Energy's academic and environmental experts group into a group to determine any immediately available measures to improve environmental performance after a series of fracking
Leakage of natural gas drilling.
Fracking opens up a lot of new gas supplies, which will reduce the import of fuel, and drilling workers argue that there is methane contamination in drinking water before drilling begins.
Supporters also said that if vehicles were converted to natural gas, oil imports could be reduced in the future.
But residents near the well complained that fracking contaminated groundwater supplies, enough to ignite drinking water.
In addition, the oil well accident caused a fire, and the flood of hydraulic fracturing fluid reached the stream.
