New study: fracking doesn’t contaminate groundwater

Hydraulic fracturing also known as "fracking"

A new study was reported in the Daily Signal.

Excerpt:

Hydraulic fracturing hasn’t contaminated groundwater in Texas, isn’t an earthquake hazard, and has been a boon for the state’s economy, according to a study released Monday.

The new study’s conclusions on drinking water are in line with multiple other studies of hydraulic fracturing, popularly known as fracking.

Hydraulic fracturing is the process of drilling into rock and injecting a high-pressure mixture of water, sand, and chemicals to obtain shale gas and oil, which is produced from fractured rock. Some environmentalists argue that it can harm water supplies.

The report initiated by the Academy of Medicine, Engineering and Science of Texas, based in Austin, asserted that “direct migration of contaminants from targeted injection zones is highly unlikely to lead to contamination of potential drinking water aquifers.”

[…]“In Texas and pretty much everywhere, hydraulic fracturing has not been proven to have an adverse impact on drinking water,” Christine Ehlig-Economides, a professor of petroleum engineering at the University of Houston who is chairwoman of the task force, told The Daily Signal.

But that’s not all:

The study also explored the impact of fracking in five other areas: geology and earthquake activity; land resources; air quality; the economy; and society. It found generally positive results for each.

However, in a sixth category, transportation, the report found that fracking produced a surge of trucks, damaging pavement at an estimated cost to state taxpayers of $1.5 billion to $2 billion per year.

Even so, the study concluded that fracking adds $473 billion to the Texas economy and created 3.8 million jobs.

This isn’t the first study this year that found that fracking is safe for the environment.

The radically leftist National Public Radio reported on another study out of Duke University earlier this year:

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.

Prior to that study, there was this report from the far-left EPA, also reported in the radically leftist National Public Radio.

Excerpt:

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.”

Fracking reduces air pollution and lowers energy costs for consumers and businesses that employ consumers. What’s not to like? People on the political right like fracking, because they are aware of the science in these studies. People on the left hate science, and so they hate fracking. They don’t let science inform their views.
