Hydraulic fracturing, or “fracking” is a process in which natural gas and oil are extracted from shale rock layers deep within the earth by creating fractures below the earth’s surface. This is done by injecting a mixture of water, sand and chemicals at high pressure into wells. There are a number of environmental concerns related to hydraulic fracturing. One concern is the amount of water it takes to extract these resources – it could involve up to 5.9 billions gallons of water per day. In order for these fracking sites to get all that water 200 trucks are needed in order for this to happen. In drought prone areas of the country, this could create additional strain on the environment. The areas that are most prone to drought are areas like Texas, Florida, Georgia, Louisiana, Virginia, and Kentucky along with other states surrounding them. Droughts take place all over the United States but most severely in the south as shown in this map. The dark, dark red are the states that have the most number of drought evens occur per year.

In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
Hydraulic fracturing, also commonly referred to as fracking, is a type of drilling for natural gas and oil that started in the 1940’s. In the beginning, when a well was slowing down, dynamite or TNT were placed inside the well head and detonated to help the flow of gas and oil by expanding natural cracks and veins in the earth. This method of fracking was used extensively for almost fifty years in the United States until the easy to mine and profitable oil had been almost completely tapped. A new form of hydraulic fracking was created in the early 90’s to help capture the less available oil and gas pockets remaining in the United States. The current method of fracking begins by drilling a vertical shaft lined with several piping layers and an outer layer of cement up to 10,000 feet deep. After achieving the appropriate vertical length a horizontal shaft is cut off of the vertical shaft that can stretch to lengths up to one mile long. A mixture of sand, water, and chemicals are injected in the shaft fracturing the shale formations and release pockets of oil and natural gas. The water is brought back to the surface where the gas and oil is separated out. The issue many people have with fracking is the possible side effects of chemicals used and water contamination. With the use of fracking helping American’s reach energy independence, economic benefits, and a bridge to help attain a clean energy source; fracking should be expanded in the United States.
Ever since the process of hydraulic fracturing—or fracking—made its entrance to the oil industry, issues and problems surrounding the process have become a common occurrence. Fracking is the controversial process of horizontal drilling (see fig. 1), where millions of gallons of water mixed with sand and chemicals are pumped deep into an oil well to extract natural gas from the earth’s crust (Ehrenberg 20). This practice has even been banned in some places (see fig. 1). The methane that comes out of the earth and the water used—called fracking fluid—has the potential to cause problems with local ground water supplies. Whether or not fracking is the cause of these problems, concern should be observed during the fracking process to reduce the chances of water contamination among residential areas.
Fracking can cause harm to people, animals, and nature. When they drill into the ground they are pumping chemicals to extract the gas and oil, and this contaminates the water sources around it. “An editorial on gas extraction from the Marcellus Shale in the Post-Star, a newspaper in Glens Falls, New York, contends, “New York state simply can’t take the risk. There are plenty of places to find fuel. It’s not so easy to find a new water supply for 17 million people.”” (Hydrofracking
In the past couple of years the word fracking has been prevalent in the media whether its been mentioned in the news or in the movie Matt Damon stared in titled “Promised Land”. Many people know it as a method of extracting gas from the earth and don’t inquire further into what hydraulic fracturing actually is. Before the process is explained we should understand why it has become prevalent in the last decade. The reason Hydraulic fracturing has become so popular in the last couple of years is because of the passage of the energy policy act of 2005, which contained the Halliburton loophole. The Halliburton loophole stripped the Environmental Protection Agency of its authority to regulate hydraulic fracturing (New York Times 2009). Allowing Hydraulic Fracturing allowed companies to finally access the abundant sources of natural gas legally. This act made it possible to access the vast amounts of natural gas contained in the Marcellus Shale, which created a boom in hydraulic fracturing. What exactly is hydraulic fracturing? Hydraulic fracturing is a method of extracting oil and gas, that is not accessible by conventional drilling methods. The process, injects chemically treated water and sand at high pressures into shale rock to release the oil and gas (Pritchard 2013).
“Hydraulic fracturing involves the use of water pressure to create fractures in rock that allow the oil and natural gas it contains to escape and flow out of a well (Energy From Shale).” Fracking has served to extract natural gas and oil where other methods would not be as successful but many environmentalists argue that fracking is affecting the environment and our drinking supply of water. Although fracking is still a controversial topic, it provides Americans jobs, increases the economy of the region, and the natural gas and oil are cleaner and more affordable source of energy. The EPA recognizes that natural gas and oil are an essential part to help our planet survive but do not want fracking to come at an expense to the public health of the citizens or to the environment.
Oil and natural gas companies have developed a way to drill for natural gas, a process called hydraulic fracturing, also known as fracking. Natural gas is a flammable gas mixture consisting of methane and several other hydrocarbons that occur naturally underground. Natural gas is used as fuel for heating, cooking, and even in some automobiles like the “RideOn” buses. This technique has only recently become economically feasible with the rising prices of fossil fuels, and there is much potential for recovering natural gas through fracking. However, fracking has many waste products and unusual side effects caused by the unnatural forces and materials used. Fracking has a detrimental effect on the surrounding environment through pollution and earthquakes.
Every resource on our planet is limited. This is not surprising information as humans have known this since the beginning of existence. Eventually, oil and other resources will no longer be viable sources of energy because they will be depleted. The simple answer to this inevitable issue is hydraulic fracturing. It is currently a controversial means of finding energy and was argued both ways by Josh Fox in his film Gasland as well as Phelim McAleer in his documentary FrackNation. Hydraulic fracturing, better known as “fracking”, is a safe and efficient way to acquire the copious amounts of energy needed to power the earth.
Hydraulic fracturing, commonly referred to as fracking, is a widespread practice in the United States. Fracking is a method used to extract oil and natural gas. Scientists and citizens report detrimental side effects of hydraulic drilling. New York and Vermont have banned fracking statewide. Maryland has set a two year moratorium on fracking, so that more research can be done to show the impacts of fracking on the environment. Nationwide, many other cities and counties have banned fracking as well. All states should look into finding alternative sources of energy, instead of using devastating practices like fracking to extract non-renewable resources.
Groundwater is one of the most important resources in the world, and also one of the most fragile. Recently, the effects on the groundwater supply by hydraulic fracturing, or fracking, has become a growing concern for many, especially as the water crisis persists. Critics of fracking accuse the practice of contaminating groundwater and using too much of the water supply. As water becomes more and more valuable all around the world, it is important that these claims be taken seriously.
Do you think that fracking is good for the environment? Some people think that fracking is a good thing for America and that it could bring more oil and natural gas. Fracking causes many issues for the areas around the site they are doing it and it uses to much water.
Imagine a world where fresh and clear water was a luxury. Imagine water so contaminated with chemicals that every plant it comes into contact with dies. As the trees begin to die, oxygen levels drop. As the vegetation dies, wildlife begins to die out. The polluted water which flows through the ground into wells causes instant contamination. As the water flows out of the sink, one can strike a match and light the liquid on fire. Showering in these chemicals is out of the question. Fresh water has become a comfort, rather than a given. Could planet Earth survive this existence? If hydraulic fracturing, otherwise known as fracking, were deemed legal, this question may be put to the test. Fracking is a process in which chemicals, sand and water are used in “high volumes… to fracture gas-bearing layers of rock” (Dolesh 2). As the rock breaks, natural gas is released and then collected to be used as energy. The United States is currently sitting on a gold mine of natural gas which could stimulate our ever declining economy. The question is what price are we willing to pay for a temporary fix? Fracking is a dangerous process that should be deemed illegal due to its harmful short and long-term environmental effects.
Fracking has become a highly controversial and publicized topic due to rising concerns and growing analysis into the mutual benefits of hydraulic fracturing to retrieve natural gas and oil reserves. With concerns of water pollution, mismanagement of toxic waste and irreversible
Numerous reports have been given on the dangerous affects of hydraulic fracturing. One such affect that has been noticed is that drinking water wells near the fracturing sites have been contaminated. During the hydro-fracking process, injected fluids that help to break and keep open the rock bed where the natural gas is kept, have “been known to travel three thousand feet from the well (Goldman).” This fluid could have the potential to enter and contaminate any water well for homes around hydraulic fracturing sites. This incident is one of the major problems that people want to figure out and know about before they allow a fracturing site by them. It has been the most feared outcome of having a fracking site nearby, and it is highly appropriate. One site in Wyoming had this happen, “…in August, EPA reported that eleven of thirty-nine drinking-water wells near a Wyoming hydraulic fracturing operation were contaminated with chemicals used in the fracturing process (Hobson EPA).” In Pennsylvania, another such case occurred, “There have already been severe pollution cases in Pennsylvania, mo...
Imagine having a loved one with cancer, organ damage, nervous system disorders, or your child having birth defects. Imagine running out of clean water because the only water available is capable of catching fire. Imagine oil in rivers and animals losing their homes. See yourself caught in an earthquake where there should not be one. All of this is increased by fracking and can be prevented. The question is should fracking continue or should it be banned.
