What’s With All this Fracking? Drilling May Endanger Drinking Water [VIDEO]

The drinking water in some 19 states may have been rendered less than safe for, well, drinking due to a controversial oil drilling technique called fracking. A recent Congressional investigation reveals that no oil and gas companies have gotten permits for using diesel fuel for fracking in an apparent violation of the Safe Water Drinking Act of 1974, and with unknown effects on public health.

Hydraulic fracturing, or fracking, involves the high-pressure injection of water, sand, and chemical additives including diesel fuel (which helps to dissolve other chemicals into the fluid) into a well, far below the earth’s surface. Fissures are created and propped up in the rock formations so that natural gas and oil can more readily flow out of the well. But environmentalists and regulators have become increasingly concerned that the fracking chemicals—including toluene, xylene and benzene, a carcinogen, which are all from diesel gas—are seeping out into underground sources of drinking water, in violation of the Safe Water Drinking Act.  

In a letter to the Environmental Protection Agency on Monday, Congressional investigators charged that fracking violates the Safe Water Drinking Act, the January 31st New York Times reports. From 2005 to 2009, oil and gas service companies including HalliburtonSchlumberger and BJ Services injected 32.2 million gallons  of diesel fuel into onshore wells, in 19 states, as Reps. Henry A. Waxman (D-CA), Edward J. Markey (D-MA), and Diana DeGette (D-CO) write in the letter:

According to EPA, any company that performs hydraulic fracturing using diesel fuel must receive a permit under the Safe Drinking Water Act.  We learned that no oil and gas service companies have sought—and no state and federal regulators have issued—permits for diesel fuel use in hydraulic fracturing.  This appears to be a violation of the Safe Drinking Water Act.  It also means that the companies injecting diesel fuel have not performed the environmental reviews required by the law. 

A key question is whether the unauthorized injection of hydraulic fracturing fluids containing diesel fuel is adversely affecting drinking water supplies.  None of the oil and gas service companies could provide data on whether they performed hydraulic fracturing in or near underground sources of drinking water, telling us that the well operators, not the service companies, track that information.  We also asked about diesel fuel use in coalbed methane formations, which tend to be shallower and closer to drinking water sources.  The three largest companies—Halliburton, BJ Services, and Schlumberger—told us they have stopped using diesel fuel in coalbed methane formations located in underground sources of drinking water.  Three smaller companies reported using a limited volume of products containing diesel in coalbed methane wells but did not provide information on the proximity of these wells to drinking water sources.  [my emphases in italics]

The New York Times further notes that, while oil and gas companies have ‘acknowledged using diesel fuel in their fracking fluids,’ they have rejected the charge that doing so was illegal. The companies have instead sought to shift the blame onto the E.P.A. by contending that the agency never ‘properly developed rules and procedures to regulate the use of diesel in fracking, despite a clear grant of authority from Congress over the issue.’ 

In 2003, three of the largest oil and gas services companies —HalliburtonSchlumberger and BJ Services — signed an agreement with the E.P.A. that was to ‘ curtail the use of diesel in fracking in certain shallow formations.’  A 2004  E.P.A. investigation in 2004 failed to find any threat to drinking water from fracking, but critics charged that this decision was ‘politically motivated.’ 

And then, in 2005, in the Energy Policy Act of 2005 (sometimes referred to as the Bush/Cheney Energy Bill of 2005), Congress amended the Safe Water Drinking Act to exclude oil and gas producers from having to follow certain of its requirements. This act also created the “Halliburton Loophole’ (so-called because former Halliburton CEO Dick Cheney was said to be instrumental in its passage) which exempts companies drilling for natural gas from disclosing the chemicals involved in fracking operations—a disclosure that, under laws such as the Safe Water Drinking Act, would normally be required. These exemptions would be removed under the proposed Fracturing Responsibility and Awareness of Chemicals Act, which was introduced to both houses of Congress in June of 2009. 

The E.P.A. has again started to investigate the issue of fracking’s impact on drinking water last year. Results are not expected until 2012 at the earliest. And in the mean time, who knows what is going on to our water supply, far beneath the earth?

Reality check...
We are using computers, watching TV, driving our own vehicle to work, and other hundreds of activities requiring energy. That's the reason Oil Co.s are drilling. The demand, OUR DEMAND for energy is driving the drilling and fracking activity. So there is no way we can continue our lifestyle without drilling... not for another century at least.

So, rather that pushing for stepping back in the middle of the 18th century, we should push for our governments to force the Oil Co.s to do it right. Yes there are ways to do it right, clean and safe. It just costs more money. Money that at the end we, the consumer, will pay anyhow, so lets push them to do it right.

In case you wander, yes there are ways for clean fracking, and a simple search will give you plenty of material to read about it.

Where are the petitions to ban gas fracking in North Dakota?

There is a proposed bill in NV AB329 which is trying to get the Wild Mustangs off the Wild list of protect so that they can refuse them the rights for life sustaining water. Fracking is used to extract oil and minerals from rocks. In doing this, the water is run off and pollute the area. Please oppose the bill NV AB329 and opposed Fracking. Fracking kills whatever wild life there is and destroys any natural resources. Remember water is tne new gold and oil!

According to press-releases of friday april 8th the french government is stepping back and laws will be voted soon to forbid fracking, for shale gas and fioul alike. The former minister who signed the permits for fracking stated "....based on the current knowledge of today, that fracking threatens the environment, these permits shouldn't have been given. I made a mistake....."

Wait and see, but this looks quite good.

Mass movement can achieve things!
