The Need, Risks And Impacts

gallons of chemicals are used per fracturing (9). Pneumatic fracking has the same concept as

Hydraulic fracturing is also known as “fracking” is a technique which involves drilling down, then horizontally as far as 10,000 feet below the surface to release natural gasses stored in the sedimentary rock known as Shale. The channel is then encased with concrete or occasionally steel to allow millions of gallons of water to be injected into the wellbore. Most water used in fracking comes from surface water sources such as rivers, lakes, or other accessible bodies of water nearby. Not only is there water being funneled into the wellbore, but also a mixture of sand and other chemicals. When the high-pressure mixture is injected underground it fractures the Shale around the wellbore and creates fissures. The fissures are then held open with

The added chemicals help reduce problems such as a buildup of bacteria and mineral deposits (OSU). Fracking is a very water intensive process and uses up to four million gallons of fresh water for each well, and with about thirty-five thousand wells in the United States, fracking consumes the same amount of water as five million people (Schmidt). Most of the water used remains trapped down in the rocks where the natural gas previously was, but about thirty to seventy percent of the water resurfaces as what is called “flowback”. Flowback water is full of minerals, salts, and often times some radioactive materials.

Hydraulic fracking isn 't all good though, there are many controversial things about it. First off, water contamination is a hazard. There are many ways that the water supply could be contaminated by fracking. One way is by groundwater entering through cracks that fracking has made. The water solution that 's pumped into the ground is a mixture of water, sand, and chemicals. Water and sand make up 98% of the mixture, while the remaining 2% is chemicals. Although fracking companies have never realised the chemicals used, scientists studying wastewater have found many harmful additives. A few of these are benzene, toluene, and many acids, all of which pose huge threats to humans. For each fracking well, more than 8 million liters of

“Fracking” isn’t a word that most people are familiar with unless they are well informed or active in local government or natural gas extraction. “Hydraulic fracturing, or fracking, involves extracting natural gas from shale formations underground” (Collier, Galatas, Harrelson-Stephens, 2008). During the process known as fracking, millions of gallons of water are shot underground into shale formations to help bring the natural gas trapped inside the formations to be released so that it can surface and become available for extraction. This is the technique that is used for traditional fracking methods. Although fracking increases the states natural gas production, it also carries some negative side effects that are affecting the state and its people.

Fracking has become a highly controversial and publicized topic in recent years due to rising concerns into the potential benefits and consequences of using hydraulic fracturing to retrieve natural gas and oil reserves. With concerns over water pollution, mismanagement of toxic waste and irreversible environmental damage mounting, the practice of fracking has

Natural gas is a fossil fuel that plays a critical role in the demand and supply of energy in the United States. It is considered to be a clean burning transition fuel. Compared to coal and oil, natural gas combustion does not generate as much pollution and is therefore considered an ideal partner for renewable energy resources. Natural gas is extracted from shale formations underground that require horizontal drilling and hydraulic fracturing – “hydrofracking” or “fracking”. This drilling and extraction method is currently considered a global widespread issue due to the rapid increase in the amount of new gas wells that threatens the quality of water around the source (Entriken, Evans-White, Johnson & Hagenbuch, 2011).

In the process of fracking, the first step is to drill a hole deep into the earth vertically and then to drill horizontally and put in a steel pipe. According to EnergyFromShale.org, water, sand and other chemicals are fed down a thin pipe, or surface casing at high pressure to create cracks in the ground to release any trapped oil. A ton of water is used in this process. EnergyFromshale.com states that almost one-hundred percent of the materials used is water and part sand. According to dangersoffracking.com, one to eight million gallons of water are used for just one fracture per day. It is also stated that forty thousand gallons of chemicals are used to help the flow of the water. That is an immense amount of materials

To define fracking in latent terms, it’s the process of injecting liquids into rock at high pressures in order to extract oil and gas. The biggest concern looming over this growing industry is the environmental risks that it poses. Everyone wants oil, but no one wants it in their backyard. The cities of Texas are taking the position that fracking has more disadvantages environmentally than it has benefits that outweigh those costs. Not only is clean air in danger, but water sources are vulnerable to this environmentally-unfriendly commerce. The most common liquid used for fracking is water, and very large amounts of water are consistently required, but where is all of this water coming from? Other concerns that fracking causes such as contamination, “methane gas and toxic chemicals leach out from the system and contaminate nearby groundwater. Methane concentrations are 17 times higher in drinking-water wells near fracturing sites than in normal wells”

In Oroville, Calif. Enemies of Fracking have gained a potential argument: Drought. Fracking in one single oil well in the state of California uses roughly 87% as much water as an average family of four. The amount, why modest by National standards, has become an increasingly delicate topic when a drought was officially declared by the state earlier this year.

Another reason why the United States must make fracking illegal is because it can have a negative effect on water sources. During fracking, the fluid, which consists of over 596 toxic chemicals, is pumped into the ground, soon after, once all of the gas is extracted from the operation, some of that fluid stays deep underground, and becomes increasingly toxic as it comes picks up radioactivity, or other underground contaminants (White). These fluids can sink into aquifers and turn water into a noxious mix, even the water that comes back up is almost untreatable after coming in contact with these chemicals (Griswold). Although the dangers are well known, it is no surprise that water sources have already been contaminated due to inattentiveness.

In the last year, fracking has cost the U.S. a lot of water. Other countries and even places in the U.S. desperately need clean, drinkable water. Last year, all of the 35,000+ wells in the U.S. have used a combined total of 70 - 140 billion gallons of water.

When you look at the title of this paper you ask yourself, what is fracking, and you probably try to learn the definition so that you’ll actually understand what I am writing about. However, I am going to tell you what fracking is. What is fracking? Fracking is the injection of fluid into the ground in order to get natural fossil fuels to come to the surface, in order to use them for gas and other things (Fracking). How does fracking work? Water and sand are pushed into the ground horizontally and small explosives are inserted in order to push out oil and gas from the natural rocks that are there. Fracking has been going on for decades but there is a new type of fracking, deep fracking, that was first used in Texas in 1999 (MacDonald, 2004). There are good and bad effects of using fracking to get natural gas, many different things are effected on the Earth either way.

* Fracking will use up 4 to 5 million gallons water per well. Monthly usage would be 320 to 400 million gallons (assume 80 new wells per month).

While vertical wells do yield gas, they are mainly used as a base to connect several horizontal wells, which is where the money lies in the industry. After drilling, about “2 million to 10 million gallons of water [is used] to extract the gas” (Marsa 3-4). However, high pressured water alone will not break away the shale rock, therefore sand is added to enable further fracturing. The controversial issue fueling the debate is the third substances added to the water which allow the natural gas to escape for collection. “A cocktail of friction-reducing lubricants [are used] to make the water slick enough to slide through the pipes swiftly” (Marsa 4). A geochemist by the name of Tracy Bank conducted a study at SUNY Buffalo which concluded that the lubricant contained an abundance of toxic metals, “including uranium, barium, chromium, zinc and arsenic” (Marsa 2). This is just a short list of the negative compounds used in fracking. It is likely that the public will never get the full story as to the composition of the lubricants, as major fracking companies refuse to release that information, “claiming that doing so would reveal trade secrets” (Rahman 1). So where do these contaminants end up? After reaching the surface, the waste is emptied into tanks for storage. However, sometimes ponds are also used to hold the pollutants, therefore releasing the harmful toxins into runoffs. Once the gas has
