Even if migration of hydraulic fracturing fluids into water aquifers were possible, hydraulic fracturing fluids are typically 90% water, 9% sand, and less than 1% other compounds, many of which are common household products that appear in foods anyway.
FORBES: The Sierra Club Fails An Environmental Consistency Test
The Research Council study was not tasked with assessing water quality surrounding hydraulic fracturing.
This view is echoed by Robert Jackson, professor of environmental sciences at Duke University in the US, who has published research on ground water contamination through hydraulic fracturing.
After suffering a punishing year because of low natural gas prices, the wind power industry is keeping close watch on the prospect that water pollution from hydraulic fracturing may lead to regulation of shale gas drilling.

The EPA has never found a single instance of drinking water supplies being contaminated by hydraulic fracturing.
FORBES: The Sierra Club Fails An Environmental Consistency Test
The problem is, because of this seemingly endless flow of misleading information, the public is led to believe that any incident of water contamination was caused by hydraulic fracturing.
However, the shale rock containing natural gas is separated from underground water aquifers by impermeable layers of rock that do not allow any hydraulic fracturing fluids to migrate into underground water aquifers.

According to environmental activist groups, hydraulic fracturing puts drinking water at risk.

To get at the oil and gas trapped in shale, drillers use powerful hydraulic pumps to force water and chemicals through holes punched in the concrete-and-steel well casing.
Further, although thousands of CBM wells are fractured annually, EPA did not find confirmed evidence that drinking water wells have been contaminated by hydraulic fracturing fluid injection into CBM wells.
Shale gas is natural gas that is trapped inside shale rock and is extracted by using a technology called hydraulic fracturing, where highly pressurized water mixed with sand and chemicals is used to crack open rocks.

In its review of incidents of drinking water well contamination believed to be associated with hydraulic fracturing, EPA found no confirmed cases that are linked to fracturing fluid injection into CBM wells or subsequent underground movement of fracturing fluids.
The Energy Policy Act of 2005 exempted hydraulic fracturing operations from the Safe Drinking Water Act, freeing drilling companies from the obligation to disclose the chemicals injected into deep shale formations to shatter shale and convey gas back to the well.
Environmentalists have loudly worried that hydraulic fracturing, or fracking, may threaten water and air, though the Obama administration and many state regulators say the practice is safe when done properly.
Many federal and state regulators say hydraulic fracturing, which injects a mix of water and chemicals thousands of feet underground to crack open shale and release natural gas, is safe when done properly and thousands of sites have few complaints of pollution.
Concerns also have been raised about the possibility that hydraulic fracturing could contaminate the aquifers that supply drinking water.

New York City gets roughly half its water from the Delaware River Basin, a key area for hydraulic fracturing.
Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).
Opponents fear UK Methane will use hydraulic fracking to extract gas which they say could pollute water supplies.

The industry has boomed in recent years, thanks to a stunning expansion of drilling in previously untapped areas because of the use of hydraulic fracturing, or fracking, which injects sand, water and chemicals to break apart rock and free the gas inside.
Hydraulic fracturing, or fracking, pumps millions of gallons of water mixed with fine sand and chemicals deep into oil and gas wells to crack gas-bearing rock.
Hydraulic fracturing or "fracking" is a process of forcing water mixed with chemicals through deep wells to shatter and crack hard shale rocks to release the gas inside.
Cuomo said late Monday that he hasn't given a deadline for the state health and environmental conservation commissioners he appointed to advise him on a decision on whether to drill for gas using hydraulic fracturing, or fracking, which injects a mix of water and chemicals thousands of feet underground to crack open shale and release natural gas.
Romp the throttle at mid-rpm in third gear and you'll get a huge, hydraulic shove in the back, like God has hit you with a water balloon.
WSJ: 2014 Aston Martin Vanquish Review: No, Mr. Bond, I Expect You to
There's no doubt that critics of hydraulic fracturing a practice colloquially known as fracking that involves injecting water, sand and chemicals into underground rock to free vast reserves of gas have some legitimate concerns.
The EPA maintains that two water wells in Parker County, west of Fort Worth, were contaminated by gas from hydraulic fracturing more than a mile below it.
WSJ: Daniel Yergin on the Shale Gas Revolution: Stepping on the Gas
Hydraulic fracturing involves the injection of fluid consisting of approximately 99.5% water and sand (the rest consists of common industrial or even household chemicals or materials) through wells constructed with protective casing and cement, into producing shale formations.
FORBES: Why Anti-Fracking Groups Are Shifting Their Story From Water To Air Quality
The ingredients used in hydraulic fracturing include a small dose of chemicals (0.5%) mixed with water and sand (99.5%).
Although methane itself is not regulated as a water pollutant, the study could lead to federal regulation of the heretofore largely unregulated practice of the hydraulic fracturing, or fracking, of deep layers of shale to tap vast reservoirs of natural gas in the United States.
