Can We Prevent Water Contamination Caused By Hydraulic Fracturing?
“In 1821 decades before the first oil well was drilled, commercial shale gas was extracted in Fredonia, New York”(Sovacool 250). The availability of natural gas and its relatively clean properties has allowed the expansion of natural gas extraction. By the year 2005, the extraction of shale gas had expanded with the discovery of hydraulic fracturing. In the United States alone it has led to an enormous growth in the oil industry and this technology has been adopted by many other countries around the world including Iran, Canada, and Europe. As a result, the country is less dependent on foreign countries to meet the growing demand for natural gas, and it has improved the country’s economy while producing less carbon emissions into the atmosphere. But what is hydraulic fracturing?
Hydraulic fracturing or fracking is part of a process known as unconventional natural gas development, which refers to all operations associated with fracked wells, from well construction to the transport

If we are to make fracking safe we have to start early, by making sure that fracking sites have good safety measures in place. For example, state permitting process must make sure that these wells are not constructed poorly. In Michigan fracturing operations must construct a well pads at least 1320 feet away from the nearest stream for state leases (Burton et al 1686). I believe this will lessen the chances of contamination to nearby streams because it will make it possible to try and fix leakages before they can reach water bodies. When we do the construction properly it will be much easier to contain and mange 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.
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).
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.
Hydraulic Fracturing is a process that releases trapped natural gas by expanding cracks in the surrounding rock via the pressure created by pumping a concoction of water, sand and chemical additives, like benzene, deep underground via a well. Hydraulic fracturing dates back to the 1940’s, however it did not become popular until 2003 when natural gas companies began to explore alternative energy resources. Although hydraulic fracturing is an efficient engineering process, the act, by the engineers, of allowing it to continue is unethical because it violates the first canon of the ASCE Code of Ethics which is "Engineers shall hold paramount the safety, health and welfare of the public and shall strive to comply with the principles of sustainable development in the performance of their professional duties" (ASCE.org). It is unethical by the engineers who allow the continuation of a potentially hazardous process to continue and expand across the U.S. and the world without first proving to the public that hydraulic fracturing is safe or not through clear and concise unbiased research.
The ethical issues regarding hydraulic fracturing to extract natural gas in the Karoo are abundant and complex. Although it is not a new procedure with new technology, South Africa and especially the Karoo is not use to this term and what it entitles. There is no reason why the shale formations should not be developed to its full potential but the crisis is balancing the development and not effecting the residence living there in a negative manner. Communities was built where water was availability, industries contaminating that supply is simply unacceptable (Potter & Rashid, 2013).
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).
...t decades but recently the government has been more involved trying to regulate fracturing processes so that they are safe to the environment and to the people. Although fracking is not very well accepted, many believe that fracking is the only way to extract natural gas and oil efficiently. While others believe that it is harmful to the drinking supply of water and to the environment as all other extractions of natural resources are. Today states, the House of Representatives, and the Senate are all working to help minimize the effects that hydraulic fracturing has within communities and the environment by enforcing stronger laws and regulations within fracturing wells and fracturing companies. Hydraulic fracturing provides sufficient and clean energy that will help minimize the impact on other natural resources that are used for energy as well.
Conflicting reports make it difficult to discern just how detrimental the practice is to the environment and people. What is known is that fracking uses phenomenal amounts of water, which is becoming a scarce resource in many parts of the country. There is no doubt that the fluid used in the fracking process contains chemicals, and when released into water supplies has negative effects on these sources. Injection of flowback materials into deep wells has been definitively linked to increased seismic activity. Damage to roads due to the high traffic of trucks shipping equipment and product is astronomical. Worldwide, four countries have outright banned the practice and others are waiting for more research to be done before they continue to allow it. A few states know the devastating side effects that come with the practice, and have banned hydraulic fracturing. While there is no doubt that fracking can produce resources that are used by Americans, there is a lot of doubt as to whether it is safe or not. Hopefully, the country will follow those that have banned the practice, and adopt other safer forms of energy
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.
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...
Fracking is a pressurized, chemically treated mixture of water and sand to release and extract natural gas and petroleum from shale rock. There are many articles, studies being done, and organizations fighting for what they think is right. Environmentalist want the technique of fracking banned because it plays a part in global warming, affects our water, and causes human health problems. If fracking cannot be banned because of its necessity then it should be made safe and eco-friendly. The process involves a well being drilled vertically to the desired depth, then turns ninety degrees and continues horizontally for thousands of feet into the shale believed to contain the trapped natural gas. A mix of water, sand, and various chemicals is pumped into the well at high pressure in order to create fissures in the shale through which the gas can escape. Natural gas escapes through the fissures and is drawn back up the well to the surface, where it is processed, refined, and shipped to market. Flowback returns to the surface after the
