There is a lot of debate about fracking in the United States right now. There are valid arguments and scientific studies on both sides of the argument. This can make it hard to figure out who’s ultimately correct. On one hand, environmental activists argue that fracking is responsible for the pollution of drinking water. They point to the large number of chemicals used in the process of fracking, and make the point that some of these chemicals must be leaking into the watershed.

On the other hand, groups in favor of fracking point to the numerous safety precautions taken by drilling companies. These companies are regulated by a series of laws intended to protect the environment and local drinking water. Recently, defenders of fracking have been given another piece of evidence that is giving them a solid platform to backup their stance with.

That piece of evidence is a recent EPA (Environmental Protection Agency) report. In the report the EPA states that fracking does not threaten local drinking water supplies. The report took place over four years and looked at fracking activities across the United States.

The EPA concedes that in a few cases fracking wells have been responsible for contamination. However, they point out that these cases are few and far between. In fact, in cases where contamination has been detected, it almost always happens at wells that are violating one or more federal safety guidelines.

Fracking companies are also quick to point out that the chemicals they shoot into the ground are injected well below the watershed. In most places the watershed rests at about 2,000 to 3,000 feet. The wells that fracking companies drill go well below the watershed, up to depths of 9,000 feet. That means that these chemicals stay down in the ground, as they cannot go against gravity, and transition thousands of feet up to the watershed.

Companies also take extra precautions to preserve the watershed. All wells that are drilled have an additional amount of protection near the surface. Large amounts of concrete are poured around the fracking well closer to the surface, just as an extra precaution against any leaks.

All of these precautions protect drinking water from contamination. By following federal regulations and reinforcing wells near the surface, fracking companies strive to make their wells as secure as possible. These precautions are surely one of the reasons that the EPA concluded that fracking does not contribute to the contamination of drinking water.

However, no industrial process that uses as many chemicals as fracking can be completely clean and contamination free. Every year, rigs inject billions of gallons of fracking solution into the earth. Most of this solution is water and a small percentage is chemicals, lubricants and other compounds. Even though the solution is predominantly water, even just 2% of a billion gallons means 20 million gallons of pure chemicals.

One of the problems with fracking is that a majority of this solution is left behind in the earth. Depending on the well, only 30 to 50% of the solution used in fracking is recovered from beneath the ground. That means that every year a nearly unimaginable amount of polluted water is being left underground.

Problems also arise when that water is above ground. The fracking solution is usually stored in large tanks and ponds. Unfortunately, these storage areas are prone to dangerous spills. When fracking solution spills above ground, two things happen.

First, the solution sinks into the ground. Since thousands of gallons can spill at one time, this can add up to a significant amount of spilled solution. This water can sink down into the watershed. There, it gets mixed with clean water and is eventually used for drinking water.

The other problem associated with fracking solution spills happens when that water leaks into a local stream, river, pond or lake. When this happens the solution is carried off and it becomes mixed with pure, fresh water. This is a big problem because this type of leakage cannot be controlled. Once fracking solution leaks into a river, for instance, little can be done besides warning local residents about the danger.

More than anything else, there is one law associated with fracking that is alarming when it comes to the quality of drinking water. Fracking companies are exempt from the Clean Water Act and Safe Drinking Water Act. That means that their activities aren’t regulated by two acts which are explicitly designed to protect drinking water.

One of the larger problems with the question of fracking is that neither side has enough science to entirely disprove the other’s arguments. People who support fracking point out that spills are rare and many precautions are taken to protect drinking water.

Environmental activists argue that every year, fracking rigs use millions of gallons of potentially hazardous chemicals. Furthermore, they argue that by leaving these chemicals in the ground, fracking companies are risking watershed contamination.

Ultimately, the best way to solve the question is by doing your own local investigation. If you don’t live near a fracking rig then it’s likely you have nothing to worry about. If you do, you can take water samples and have them sent into the EPA for analysis.

It’s as likely as not that these samples will be fine and your drinking water is safe to drink. On the other hand, if there are chemicals present, you’ll be able to research them and discover if they potentially came from a fracking rig. Once you know what’s in your water, you’ll be able to take steps. Buying a water filter or filing an EPA complaint are all valid options.

North Carolina Fracking Bill That Would Block Chemical Disclosure

North Carolina Republican Lawmakers Push For A Bill to Give Jail Time To Anyone Who Discloses Chemicals Used In Fracking Operations.

Guest post by Wes Deyton, Wildlife Photographer and Activist

ncfrackingNine Republican lawmakers have co-sponsored a bill called the Energy Modernization act. This bill is coming up for a vote in the Senate. The Energy Modernization act will make it a class one felony to disclose the chemicals involved in the fracking process. The Energy Modernization act, if passed, would require companies involved in fracking to submit a list of their chemicals to the state geologist, who will keep the list locked away in case of accident or emergency.

Under the Energy Modernization act, unauthorized disclosure of the chemicals involved in fracking can result in up to 1 year in prison, or community service, depending on a person’s previous criminal record.

From BillMoyers.com: The disclosure of the chemicals used to break up shale formations and release natural gas is one of the most heated issues surrounding fracking. Many energy companies argue that the information should be proprietary, while public health advocates counter that they can’t monitor for environmental and health impacts without it. Under public pressure, a few companies have begun to report chemicals voluntarily.

North Carolina has banned fracking until the state can approve regulations. The bill introduced Thursday, titled the Energy Modernization Act, is meant to complement the rules currently being written by the North Carolina Mining & Energy Commission.

Fracking is controversial method of extracting oil and natural gas from rock, deep within the earth. Fracking uses high pressure water sand gravel and chemicals to extract the natural gas from between layers of rocks.

Fracking has been blamed for contaminated ground water, birth defects, and cancer. All this secrecy begs the question… Is the Energy Modernization act about protecting trade secrets or preventing a public outcry, if the public found out what kind of chemicals will be used at fracking sites in North Carolina?

Gasland: The Dangers of Fracking to People and Wildlife

The Oscars are coming on Sunday, and one of the movies up for best documentary, Gasland, has a scene in which a woman goes down to her local creek and discovers that after fracking wells had been dug on her land, animals, including rabbits, birds, frogs, began dying. She is horrified and keeps the animals in her freezer as evidence, but no one takes her seriously.

What is fracking?

I hadn’t even heard of fracking until we received our annual holiday letter from a friend in Pennsylvania who spoke about how her town is being invaded—not by an army, but by the gas and oil industry. Her family has lived in the same farmhouse for generations, but now her way of life is threatened because of fracking.

Fracking, or hydraulic fracturing, is a means of natural gas extraction used in deep natural gas well drilling. Once a well is drilled, millions of gallons of water, sand, and chemicals are injected, under high pressure, into a well. The pressure fractures the shale and props open fissures that allow natural gas to flow more freely out of the well. Fracking uses a mixture of hundreds of chemicals and millions of gallons of water per frack. This water then becomes contaminated and must be cleaned and disposed of.

Fracking is being touted as an alternative energy source that has few environmental consequences and as a means of employment for people in depressed areas. That’s all fine and good, except there are huge problems with fracking, namely that it may taint drinking water, its waste water potentially harms both people and wildlife, and it causes innumerable other problems, including possible health issues for people who live near the wells.

Here are just a few of the problems of fracking, from the Gasland site:

–For each frack, 80-300 tons of chemicals may be used. Presently, the natural gas industry does not have to disclose the chemicals used, but scientists have identified volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene and xylene.

–In 2005, the Bush/ Cheney Energy Bill exempted natural gas drilling from the Safe Drinking Water Act. It exempts companies from disclosing the chemicals used during hydraulic fracturing. Essentially, the provision took the Environmental Protection Agency (EPA) off the job. It is now commonly referred to as the Halliburton Loophole.

–The average well is up to 8,000 feet deep. The depth of drinking water aquifers is about 1,000 feet. The problems typically stem from poor cement well casings that leak natural gas as well as fracking fluid into water wells.

The Halliburton Loophole

The filmmaker Josh Fox interviewed people all over the country, people who were desperate to get help, but couldn’t. Why couldn’t they get help? Because of the Halliburton Loophole, people are powerless because the gas and oil industry is not obligated to report which chemicals have been used in fracking. Therefore, they aren’t responsible for any possible health or environmental problems associated with fracking.

For me, the saddest interview was one with a rancher whose way of life for generations is threatened by fracking. He’s trying to raise cattle in the old-fashioned way on a small family-owned ranch, but he is worried that the water the cattle drink and the grass they eat is now tainted and he might have to leave his land.

The filmmaker visited fracking sites where the waste water had collected near the wells, a virtual petri dish of toxic chemicals, which wildlife, including, of course, frogs, could easily have access to. What surprised us was how widespread fracking has become. It isn’t just in a few places here or there, but in hundreds of places across the country.  Click here to see the areas of the U.S. where fracking is occurring.

The oil and gas industry is so powerful in this country that it actually tried to have the Academy of Arts and Sciences retract the Oscar nomination from Josh Fox. Luckily the issue is starting to get some publicity. The actor, Mark Ruffalo, for example, has taken up the anti-fracking cause.

We highly recommend seeing this film (it’s easily available; we rented it from Netflix). The film trailer from HBO is below.
