Marcellus Shale drilling causes a problem because it involves the use of hundreds of deadly chemicals. Over three hundred (environmental) chemicals are used in the Marcellus Shale drilling process. According to Howells, author of the article “Don't Frack with Our Water!”, these chemicals are particularly dangerous because the companies that use them do not tell the public what specific chemicals are used. However, through the study of chemicals, it is possible to identify some of them. Some of the chemicals found in fracturing fluid and wastewater have been identified as carcinogenic. Many of the other chemicals have been found to be harmful to humans (environmental). According to Griswold, author of the article “The Fracturing of Pennsylvania,” wastewater is a combination of several chemicals resulting from the fracking process. Not only does this wastewater contain chemicals originally used in drilling, but it also contains harmful substances that come from the earth such as salts and other compounds (Griswold). Hundreds of chemicals are used when drilling in the Marcellus Shale; therefore, the process can cause contamination and pollution. According to Marc Levy and Mary Esch, because Marcellus Shale drills go so deep underground, the water is more likely to be polluted. According to the article “Methane Gas and Its Removal from Wells in Pennsylvania,” methane is a chemical that can contaminate drinking water due to drilling. Too much methane can be harmful to humans (Swistock and Rizzo). According to the article “Hydrofracking” water sources are also at greater risk of being polluted if a drill is installed nearby. Some of the contaminated wastewater created by this process remains in the… middle of the paper… and regulations are now in place covering enclosures and other equipment (Regulations). If there were more rules like this, there would be fewer disruptions and less contamination. There may also be fewer spills or related accidents if there were more regulations on the disposal of these dangerous chemicals. The way chemicals are disposed of should be monitored (Howells). Drilling the Marcellus Shale is a dangerous process with many consequences. The Marcellus Shale industry is said to create new jobs and be a “clean” (environmental) energy source (Griswold). However, this process uses hundreds of deadly chemicals, causes pollution and is subject to few regulations. One solution to these negative consequences would be to create and enforce more regulations. After all, if you had to choose between safe resources and a cheap, risky energy source, which would you choose??
