I doubt this will be interesting to the Bill Nye / Neil deGrasse Tyson socialist crowd, but it will be interesting to conservatives, who do care about the latest peer-reviewed research.
This was reported by the radically leftist National Public Radio:
Fracking the Marcellus Shale did not pollute groundwater in northwestern West Virginia, but wastewater spills did contaminate surface water, according to a new study from Duke University.
[…]The study was unique in that it monitored drinking water wells and surface water over three years, a longer time period than previous research on the impact of fracking on drinking water. The study also used multiple methods of determining the source of the pollution, and was able to draw on baseline water quality data.
“Based on consistent evidence from comprehensive testing, we found no indication of groundwater contamination over the three-year course of our study,” said Avner Vengosh, professor of geochemistry and water quality at Duke’s Nicholas School of the Environment. ”
[…]The peer-reviewed study was published recently in Geochimica et Cosmochimica Acta, a European journal.
[…]Vengosh said the baseline data, gathered from drinking water wells before shale gas drilling occurred nearby, boosts their confidence in the results. A total of 112 water wells were sampled over three years, with 20 sampled before drilling or fracking occurred.
Now, I know that Democrats will not like this study, but the study was rigorous and thorough:
David Yoxtheimer, a hydrogeologist with Penn State’s Marcellus Center for Outreach and Research, who was not involved in the study, said the report is comprehensive in that it used a number of different tools to determine the source of contamination.
“This is a good example of an objective study,” said Yoxtheimer. “They kept their scientific glasses on and looked at it objectively. It’s the type of science we need more of out there. Collect data without motive and come back and report.”
Prior to this study, we had a peer-reviewed PNAS study:
Now comes a study, conducted by scientists at the University of Texas and published in the Proceedings of the National Academy of Sciences — and co-financed by one of the highest-profile environmentalists in the country — that shows much smaller amounts of methane emissions associated with fracking, far less than environmentalists and the Environmental Protection Agency have contended.
[…]The study, billed as the first to measure the actual emissions of methane from natural gas wells, finds these emissions were, in some cases, only about 2% of the most recent national estimate by the EPA in 2011. An upcoming EPA rule, effective January 2015, requires all methane to be captured when liquids are removed after drilling.
[…]“For those wells with methane capture or control, 99% of the potential emissions were captured or controlled,” the study notes.
[…]Thanks in large part to fracking, energy-related carbon dioxide emissions in 2012 were the lowest in the U.S. since 1994, at 5.3 billion metric tons. With the exception of 2010, emissions have declined every year since 2007.
Bill Nye and Neil DeGrasse Tyson didn’t like that study, because it was experimental science.
They also hated this report from the far-left EPA, also reported in the radically leftist National Public Radio.
The Environmental Protection Agency says it finds no evidence that hydraulic fracturing — better known as fracking — has led to widespread pollution of drinking water. The oil industry and its backers welcome the long-awaited study while environmental groups criticize it.
“We found the hydraulic fracturing activities in the United States are carried out in a way that has not led to widespread systemic impacts on drinking water resources,” says Tom Burke, Science Advisor and Deputy Assistant Administrator of EPA’s Office of Research and Development. “In fact, the number of documented impacts to drinking water resources is relatively low when compared to the number of fractured wells,” he adds.
The EPA’s draft assessment was conducted at the request of Congress. “It is the most complete compilation of scientific data to date,” says Burke, “including over 950 sources of information, published papers, numerous technical reports, information from stakeholders and peer-reviewed EPA scientific reports.”
I remember telling Democrats in my previous job about these peer-reviewed studies and DOE reports and EPA reports, and they denied all of this data. I guess they had their feelings roused by carefully produced Hollywood movies, and their worldviews have been set in stone. They believe what they believe, and the strength of their beliefs are not going to be affected by peer-reviewed science.
