Gasland (2010) was created by Josh Fox in reaction to gas companies seeking to buy his land. Disturbed by intrusion to his normal way of life, he searched for answers and documented them in a film. The documentary explains the hydraulic fracturing process and lists health interviews with residents living near fracking sites. Half a decade later, fracking has depleted shale areas and fluctuated past the original 34 states during the making of the film. The article “The Fracking Industry’s Dishonest Response to ‘Gasland’” from The Nation website announced that the gas industry released “Truthland” in order to improve relations with the public. The oil/gas industry has certainly had its moments in the spot light and have sat under the interrogation …show more content…
The chemicals used in fracking will first be examined. According to the World Book Encyclopedia of Science, hydrogen sulfide, benzene, and toluene are toxic aromatics derived from tar and naphthalene. Thiol groups (SH) are more reactive than alcohol groups, but less reactive than hydroxyl groups. Sulfur compounds typically have a pungent odor similar to rotten eggs. However, increased oxidation of hydrogen sulfide would result in sulfonic acid. “Benzene is the simplest aromatic compound.” As an excellent solvent, it can produce a variety of derivatives with minimal reagents. Its characteristic bonding, unconventional by regular electron bonding, makes it extremely volatile. As a result, its use is banned outside of laboratory and industry use. Toluene is described as “identical to benzene except that one of the hydrogen atoms has been replaced by a methyl group. It is easily synthesized from benzene, so it is also a powerful solvent. Applications range from adhesive purposes, surface coating, and as a starter for TNT (tri-nitro-toluene). Xylene is “similar to toluene in structure, except that a further hydrogen atom has been displaced from the ring by a methyl group.” It is another solvent derived from tar and naphthalene by the same technique used for isolating benzene and toluene. (74-76). Because these chemicals are sourced from oil and gas, their presence in other mixtures including water would introduce combustive properties to the solution. These volatile organic compounds are not only flammable, but also carcinogenic, toxic to life-sustaining processes. Glycol Ethers are toxic fracking chemicals that have the ability to burn through membranes, which can trigger extreme neurological damage. Besides from toxic, it is near impossible to remove even with reverse osmosis filters. Because it is impossible to remove glycol
The percent yield of products that was calculated for this reaction was about 81.2%, fairly less pure than the previous product but still decently pure. A carbon NMR and H NMR were produced and used to identify the inequivalent carbons and hydrogens of the product. There were 9 constitutionally inequivalent carbons and potentially 4,5, or 6 constitutionally inequivalent hydrogens. On the H NMR there are 5 peaks, but at a closer inspection of the product, it seems there is only 4 constitutionally inequivalent hydrogens because of the symmetry held by the product and of this H’s. However, expansion of the peaks around the aromatic region on the NMR show 3 peaks, which was suppose to be only 2 peaks. In between the peaks is a peak from the solvent, xylene, that was used, which may account to for this discrepancy in the NMR. Furthermore, the product may have not been fully dissolved or was contaminated, leading to distortion (a splitting) of the peaks. The 2 peaks further down the spectrum were distinguished from two H’s, HF and HE, based off of shielding affects. The HF was closer to the O, so it experienced more of an up field shift than HE. On the C NMR, there are 9 constitutionally inequivalent carbons. A CNMR Peak Position for Typical Functional Group table was consulted to assign the carbons to their corresponding peaks. The carbonyl carbon, C1, is the farthest up field, while the carbons on the benzene ring are in the 120-140 ppm region. The sp3 hybridized carbon, C2 and C3, are the lowest on the spectrum. This reaction verifies the statement, ”Measurements have shown that while naphthalene and benzene both are considered especially stable due to their aromaticity, benzene is significantly more stable than naphthalene.” As seen in the reaction, the benzene ring is left untouched and only the naphthalene is involved in the reaction with maleic
The boiling point of the product was conducted with the silicone oil. Lastly, for each chemical test, three test tubes were prepared with 2-methylcyclohexanol, the product, and 1-decene in each test tube, and a drop of the reagent were added to test tubes. The percent yield was calculated to be 74.8% with 12.6g of the product obtained. This result showed that most of 2-methylcyclohexanol was successfully dehydrated and produced the product. The loss of the product could be due to the incomplete reaction or distillation and through washing and extraction of the product. The boiling point range resulted as 112oC to 118oC. This boiling point range revealed that it is acceptable because the literature boiling point range included possible products, which are 1-methylcyclohexene, 3-methylcyclohexene, and methylenecyclohexane, are 110 to 111oC, 104oC, and 102 to 103 oC. For the results of IR spectroscopy, 2-methylcyclocahnol showed peaks at 3300 cm-1 and 2930 cm-1, which indicated the presence of alcohol and alkane functional group. Then, the peak from the product showed the same peak at 2930 cm-1 but the absence of the other peak, which indicated the absence of the alcohol
In order to separate the mixture of fluorene, o-toluic acid, and 1, 4-dibromobenzene, the previously learned techniques of extraction and crystallization are needed to perform the experiment. First, 10.0 mL of diethyl ether would be added to the mixture in a centrifuge tube (1) and shaken until the mixture completely dissolved (2). Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent.
The process of hydrofracking allows for a new source of renewable energy, but it takes a toll on the environment. Five-hundred plus of toxic chemicals like hydrochloric acid, sodium chloride and formic acid are left in the ground. The chemicals produce gases, there...
The documentary ‘Gasland” is a telling tale of the terrible consequences of natural gas mining in the US. The filmmaker, Josh Fox, travels around the country visiting different homes that are in very close proximity of natural gas drilling sites after receiving a $100,000 offer from a natural gas company to use his land as a drilling site . The film focuses on how the drilling sites not only leave ugly scars on the land, but also the horrendous health problems people get from drinking the contaminated groundwater.
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.
The United States has an immense amount of proven natural gas reserves that could become a major source for the nation's energy future (1). The mining of the natural gas resources have become feasible and cheaper due to the advancement of hydraulic fracturing technologies which have increased the amount the extraction and enabled “greater access to gas in shale formations” (2). Hydraulic fracturing, or fracking of shale formations has positive benefits that includes economic growth and the natural gas extracted is cleaner than coal and oil, however it has caused serious environmental problems and possibly could be the cause of recent seismic activity in areas where fracking operations exist (3).
The people who are being asked permission to transform their land into drilling sites for natural gas have more reason to be concerned than most because it will affect them more directly than people who do not live in that specific area (although it does affect people who do not live in the vicinity as well). Although fracking may seem to concern to only a small group of people, it should also concern anyone who cares about doing what is safe for our country's citizens. The truth is, fracking is extremely dangerous, not only because of the negative effects on the environment, but also because it could make people ill.
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 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.
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.
He set the record state by tracing Josh Fox’s footsteps in Gasland. One of the most important discoveries found in his research was the absence of toxic water in Dimock, Pennsylvania. Other interviews and research uncovered citizens with no health issues as a result of fracking unlike Josh Fox’s take on children acquiring asthma and older men and women with cancer. The scientists involved in the film speak in a clear, and understandable voice and explain those nasty sounding chemicals that frightened Gasland viewers. Seismic activity near fracking sites was also analyzed and found to show no direct effect on earthquake happenings. McAleer also makes a point to show why fracking should be available in other countries. A poor, old woman in Russia explains her extremely high energy bills are causing her to sell her belongings. The documentary is narrated and filmed in a way that triumphed over Gasland in every aspect.
Before one can see the devastating effects of fracking, one must first understand how fracking works. As previously stated, the main intent of hydro-fracking is to access and harvest natural gas that lies below the surface of the Earth. Having formed over 400 million years ago by the collision of tectonic plates (Marsa 3), the Marcellus Shale plays host to a gold mine of natural gas, which is currently at the center of the fracking debate in the Northeastern region of the United States. Unfortunately, access...
environmental damage mounting, the practice of fracking has only quietly expanded and profited. This concealed expansion into the nation’s backyard has only
Segments of mini interviews were included to provide a firsthand perspective on the disturbing reactions of the effects of the oil wells. This is where the “fracktivists” discussed their experiences of health concerns with their families as well as the lack of say they have in the companies bringing in these pads to their neighborhoods. I found this to be very informative because not only are the families facing health concerns from the fracking, but they also have no say in the production of the oil wells and can only relocate to escape the issue. However, this idea plays an important role within the film to the parents of children who have experienced health concerns from the fracking; they choose to take a stand against the industries and show that no profit should out weight a child in harm. In a short clip, we see how the hydraulic fracking has exposed serious health concerns on many different levels.
