The process of Hydraulic Fracturing is a process that 90% of natural gas wells in the United States use to extract gas from the ground. The first step in fracturing is digging anywhere straight into the ground Fractures are created by pumping large amounts of fluids at high pressure down a wellbore and into the rock formation. Hydraulic fracturing fluid commonly consists of water, proppant and chemical additives that open and enlarge fractures within the rock formation. These fractures can extend several hundred feet away from the well. The proppants - sand, ceramic pellets or other small incompressible particles - hold open the newly created fractures.
Once the injection process is completed, the internal pressure of the rock formation causes

The contaminated water is used for drinking water in local communities. There have been over thousands of documented cases of water contamination near fracking areas as well as cases of sensory, respiratory and neurological damage due to ingested contaminated water. New York Times reported that it obtained thousands of internal documents from the EPA, state regulators and fracking companies, which reveal that "the wastewater, which is sometimes hauled to sewage plants not designed to treat it and then discharged into rivers that supply drinking water, contains radioactivity at levels higher than previously known, and far higher than the level that federal regulators say is safe for these treatment plants to handle."A single well can produce more than a million gallons of wastewater, which contains radioactive elements like radium and carcinogenic hydrocarbons like benzene. In addition, methane concentrations are a lot higher in drinking-water wells near fracking sites than in normal wells. And theses agents have had reported cases of Only 30-50 percent of the fracturing fluid is recovered; the rest is left in the ground and is not biodegradable.“We’re burning the furniture to heat the house,” said John H. Quigley, former secretary of Pennsylvania’s Department of Conservation and Natural Resources. “In shifting away from coal and toward natural gas, …show more content…
The study was done in over 860,000 buildings from varying counties, mostly homes. Radon is A gas that is radation formed by the decay of uranium in rock, soil and water, radon—odorless, tasteless and invisible—moves through the ground and into the air, while some remains dissolved in groundwater where it can appear in water wells. It is the second leading cause of lung cancer worldwide, after smoking. The EPA estimates approximately 21,000 lung cancer deaths in the U.S. are radon-related."Between 2005-2013, 7,469 unconventional wells were drilled in Pennsylvania. Basement radon concentrations fluctuated between 1987-2003, but began an upward trend from 2004-2012 in all county categories," the researchers
In the video “Fracking Hell: The Untold Story” by Link TV explains how natural gas has been a huge problem not only for the earth in general but for everyone and everything living in it. The video explains how North East of Pennsylvania is having difficulties to conserve a healthy environment and people. North East of Pennsylvania is the main sources to extract gas and send it throughout the United States for gasoline and so on. However, this action is wonderful for the cost of gas, but has a huge impact on the environment and the people living in Pennsylvania. A lot of people in this state are worried having health issues because everything is not usable is being thrown out to the rivers where they get their fresh water.
Hydraulic fracturing, also called fracking, is a technique designed to release the gas and oil from shale rock hidden underneath earth’s surface. The term fracking itself is referring to the point at which the shale rock is broken open by a high-pressure mixture of water, sand, and chemicals. Oil and gas fracking can be dangerous to the environment and also to humans. “In 2011, energy company Cuadrilla suspended test fracking operations near Blackpool, in Lancashire, after two earthquakes of 1.5 and 2.2 magnitudes hit the area. A subsequent study found it was highly probable that shale gas test drilling triggered the tremors” (BBC). Although these tremors were too small to do any damage above ground, this was still a test drill. If an oil rig were to become operational, the tremors could increase in magnitude, causing significant damage both above ground and underneath the earth’s
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.
Gas in shale formations are“low in permeability,” making it very tedious to extract, but with the increase in technological knowledge in fracking and horizontally drilling into shale beds, the vast reserves of natural gas resource could be extracted (4). Fracking is a large industrial operation that boost the “productivity of a oil or gas well” (5). It is a process by which, under very high pressure, a mixture of water, chemicals, and sand, are pumped into shale formations that causes fractures in the rocks to open wider or create new fractures that would allow otherwise trapped oil and gas to flow into the wells (6).
There are many potential adverse health impacts caused by the chemicals used at the drilling site, which are later often unintentional released into the environment. These chemicals are hazardous and as Witter et. al. (2008) state “some of the chemicals used in this process are brought to the surface, potentially contaminating soil, air, and water, while some of the chemicals are left underground, potentially subsurface aquifers” (4). This makes it difficult to track which chemicals are causing effects and where they are coming from. Another piece to the puzzle is that the drilling companies do not disclose the full-list of chemicals so there is a great mystery in what chemicals and what concentrations are used in the process (Lauver 2012:383). However, recently there researchers have begun to breakdown the chemical identities and concentrations.
5). The high mortality rates are related to the environmental exposures of the coal mining along with other factors such as smoking, poverty, education, age, race and sex. “Higher lung cancer incidence and mortality in the Kentucky Appalachia is thought to result from higher smoking rates and correlates of poor socioeconomic conditions which limits the population access to health care” (Hendryx, O'Donnell, & Horn, 2008, p. 2). The population residing in coal mining areas, are exposed to contaminated water and air from the coal mining and there is a concern for respiratory illnesses related to the pollutants. The fumes or toxin released from the coal mine, this places the individual at a risk for respiratory issues such as emphysema, black lung, brown lung and
While methane is not a rare contaminant in drinking water wells, the fracking process seems to allow more methane to seep into the wells. A study headed by Duke University’s Robert B. Jackson, a professor of Environmental Sciences, shows that in Pennsylvania, drinking water wells within one kilometer of fracking sites contain nearly six times more methane than in wells farther away (Banerjee). Methane, no matter where it is contained, is flammable, thereby posing a risk for explosion, which is not good for homes. Reports show that a fracking site in Dimock, Pennsylvania caused methane to leak into a water well, where it detonated, leading to even further contamination of other water wells and homes (Henheffer 30). The domino effect presented here raises fear in critics of fracking, who seek only to stop the process from happen-
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
Fracking is quickly becoming a debatable topic in our society today. The practice involves injecting fluid into the ground to fracture rock in order to release natural gas. It sounds like it would be a safe way to harness fuels in the earth’s surface, but it actually is a danger to our environment. Because of the dangers of fracking, what little fresh water remains on earth is being contaminated. It is also releasing toxins into the airs creating contaminated air and acid rain. Because of the many health and environmental dangers of fracking, it should be stopped immediately to help prevent more worldwide health issues down the road.
Although there have been no intensive studies on the drinking water that could be linked to fracturing practices, many people believe it could be harmful to anyone that consumes the water. The EPA and other strong environmentalists are pushing towards more strict regulations on fracking. Contrary to that belief Dr. Charles Goat stated, “drilling for natural gas in itself doesn't pose a threat to air and water quality, if it‘s done properly.” Research has also been done that fracking has little to no impact on the groundwater. Companies also use safeguards to reduce the threat of air contamination from fracking engines and compressors. Local communities and fracking companies work together to reduce noise, traffic, and other environmental factors of fracking. Water is often recycled to use in other fracturing procedures. Fracking companies are working to make fracking less hurtful to the environment and to the local community (Energy from Shal...
EnergyFromShale.org shows the fluid mixture is comprised of 90% water, 9.5% propping agents such as sand, and 0.5% chemical additives. Some of the chemicals found in this mixture are: sodium chloride, ethylene glycol, borate salts, sodium carbonate, guar gum, and isopropanol. Proponents of fracking will lead you to believe that the chemicals used are essentially harmless, and found in such small amounts as to have negligible side effects. On the CDC website, ethylene glycol is described as an odorless liquid with a sweet taste. When ingested it breaks down into toxic compounds. A person’s central nervous system, heart, and kidneys are affected. Large amounts of ethylene glycol can be deadly. While many say that the 0.5% amount of chemicals used is such a small amount, they are traceable amounts. Additionally, drilling companies are supposed to treat the fracking fluid before it is injected into the ground, left to dissipate, or released into surface water. The EPA claims that flowback is properly treated before it is disposed of, and that it is regulated by the National Pollutant Discharge Elimination System. After treatment, the EPA Underground Injection Control program is supposed to regulate the flowback being injected underground to dispose of it (epa.gov.,
Radon gas was found in the 1870s, when some scientists were mining for ore in Ore Mountains in Schneeberg, Saxony. The area has a high content of radon in the tunnels because the area has been mined since the 1470s. The scientists later discovered that 75% of the miners died from lung cancer but it did not shut down the tunnels until 1950.
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.
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...
In her book Coal A Human History, Barbara Freese states "The mundane mineral that built our global economyand even today powers our electrical plantshas also caused death, disease, and environmental destruction" (front flap) Today, coal provides for more than 55% of the electricity generated in the U.S. (Cullen, Robert Vol.272) Coal miners have had one of the most dangerous jobs in history before government regulation. Many miners had to work underground for 10 + hours a day and 6 days a week(Cobb, James "Coal") The number of deaths per year is the equivalent of a Titanic going down in the nation's coal fields each year (Turkington, Carol) According to James Cobb from the World Book Online Reference Center mine safety involves four main types of problems including accidents involving machinery, roof and rib failures, accumulations of gases and concentrations of coal dust.
