Shale gas is a remarkable deposit of natural gas that is largely untapped because of the difficulty in obtaining it. Advanced petroleum extraction technics has made this untapped natural gas more lucrative. Hydraulic fracturing (fracking) is the advanced technic of extracting gas from shale rock formation. The environmental impacts of hydraulic fracturing have surpassed the endurance afforded it. This paper discusses the impact of fracking, the challenges of wastewater management, with a focus on the legal and regulatory hurdles associated with the practice of underground injection of wastewater, and ways in which the government through policies can curb the concerns.

Shale extraction has brought both economic growth and environmental destruction. The current United States shale gas thriving in the opinion of advocates has begun a new age of low-priced, clean domestic energy and widespread economic benefits. However, there have been strong calls to assess the public health impact; associated risks to human health and safety, the ecological impact; habitat fragmentation and toxic emissions (to air, water and soil), the socioeconomic wellbeing of impacted communities, as well as the overall effects on global climate.
In this article, while an attempt is made to discuss some of the many adverse impact of fracking, consideration is given to focus discussion on wastewater management, its challenges and

‘So companies drill down, often a mile or more. They drill sideways through a shale layer that might be only a hundred or a couple hundred feet thick. And once they’ve drilled out sideways a mile or two, then they’ll pump water, sand, and chemicals underground at very high pressure to crack the rock and free the gas’ . Fracking fluid is mostly water, and each fracking job takes 2 to 4 million gallons of water per well. Once pumped underground, several million gallons flow back to the surface as wastewater. Massive water withdrawals from rivers and streams occur to achieve this process, thus resulting in a major ecological impact; ‘stream/river stress’. Another ecological hazard is habitat fragmentation stemming from the siting of oil well pads, pipelines and supporting infrastructure. Aside these toxic emissions to air, water and soil also affect the ecological domain. Potent greenhouse gas such as methane and particulate matter from compressors and flaring5 pose potential damage to the quality of air inhaled by the residents and community in
Hydraulic fracking isn 't all good though, there are many controversial things about it. First off, water contamination is a hazard. There are many ways that the water supply could be contaminated by fracking. One way is by groundwater entering through cracks that fracking has made. The water solution that 's pumped into the ground is a mixture of water, sand, and chemicals. Water and sand make up 98% of the mixture, while the remaining 2% is chemicals. Although fracking companies have never realised the chemicals used, scientists studying wastewater have found many harmful additives. A few of these are benzene, toluene, and many acids, all of which pose huge threats to humans. For each fracking well, more than 8 million liters of
Fracking is a process that involves combining water with various toxic chemicals to create frack fluid. This chemical is highly toxic and can return to the surface, polluting water and destroying ecosystems and communities. This article includes various facts and statistics of fracking’s effect on the environment. The evidence of its harmful effects is laid out in an easy to read and cite format. “Fracking’s Environmental Impacts: Water” will provide supporting
The environmental risks that accompany fracking are potentially hazardous. In order to frack, thousands of acres of forests need destroyed to allow roadways the space they need to exist (Lampe 38). However, these roadways allow erosion to occur due to the lack of vegetation (Lampe 38). Along with erosion, siltation occurs and sand, soil, and mud sink to the bottom of rivers, and ponds (Lampe 38). Therefore, the animals living in these habitats may migrate, or simply just die. Trees situated on the acres of land for hundreds of years would have to be chopped down to make way for roadways. In some cases, depending on where the oil reservoir is located, the state declares eminent domain on houses and pays the landowners. Consequently, the houses will be destroyed and the oil reservoirs will be fracked.
Hydraulic fracking has been known to release ‘more than 650 chemicals”( source 3), because of this people who are living ‘near these wells fear their health may be harmed” ( source 3). Even though hydraulic fracking has not caused any known health problems there is still the threat that could come soon when more and more well build up. This could also harm the wildlife and could cause their habitat to be destroyed.
That is more people who live in New York City and in Michigan. Drilling and extraction of natural gas are known to be seriously toxic to humans and animal. A few of the many chemicals are hydrochloric acid, benzene and formaldehyde. Which all have a serious effect for human health and wildlife. Fracking can cause birth defects, cancer, bloody noses, asthma, diarrhea, dizziness, migraines, nerve pain, and skin rashes. Fracking causes earthquakes more and more frequent and the cause is almost certainly fracking and the disposal of wastewater. The earthquakes caused by fracking have not caused much damage yet, but with a call for more drilling. Seismologists are learning more about faults no one knew existed. Fracking has contaminated lots of peoples water some people have complained to be able to light their water on fire because of large amount of methane gas. It has added to the problem of are air
The issue of whether we should continue fracking without research has been widely debated around the world. The issue is important because it has fundamental environmental concerns and economic questions about the process of hydraulic fracturing. “Fracking” is the process of penetrating down into the earth before a high-pressure water mixture is absorbed at the rock to release the gas inside. Water, sand, and chemicals are then inserted into the rock with compression which allows the gas to flow out to the head of the well. Fracking fluid, which can be polluted with heavy metals like arsenic, known human carcinogens, has seeped into local waterways and polluted groundwater. People who live near fracking wells have a heightened danger of developing cancer, asthma, and other serious ailments associated with inhaling or ingesting the toxic chemicals involved in the fracking process. Countries approach fracking and researching much differently from each other. The injection of fluid into shale beds at high pressure to extract petroleum resources has been happening across the United States of America at rapid pace. By 2003, a gigantic public relations campaign was launched to lobby Congress to pass what is
The actual technique involves “pumping a slurry of water, sand and chemicals underground to fracture shale formations and release hydrocarbons” ("Fracking", 2013, p. 276). Modern procedures use a high degree of manipulation in order to extract the natural gas. The natural gas from fracking is dispersed in rock, and can only be retrieved by using specialized removal techniques (Palliser, 2012). These specialized techniques have many unintended consequences. For instance, the current method of fracking may cause the issue of flowback. Flowback occurs when the internal pressure of the rock formation causes the injected watery, chemical mixture to return to the surface with other naturally occurring substances (Palliser, 2012). This flowback is often injected back underground or can be processed by wastewater treatment plants, where it is later discharged as surface water (Palliser, 2012). Indisputably, the disposal and generation of flowback is one of the main concerns regarding hydraulic fracking. The wastewater developed from fracking procedures is often inappropriately handled and is sometimes sprayed onto rural roads and forests (Finkel & Hays, 2013). As a result, the surface water may come in contact with living organisms and can cause a plethora of issues. For fracking opponents, their driving force is the ill effects of fracking on the environment and overall health. Similarly, the possibility of drinking or coming in contact with chemically laden byproducts
Hydraulic Fracturing (fracking) is the process of drilling into the ground and pumping sand, water, and fracking fluid at high pressures in order to extract natural shale gas that was previously unattainable. This process comes with environmental issues: the chemicals from the fracking fluid can contaminate nearby drinking water wells and harm the citizens of that area. Despite the fact that there have been several contaminated drinking water cases reported, there is little being done about this matter. This paper analyzes the available research that asserts why fracking is a dangerous process that should be banned immediately. The intended audience is my peers and instructor, as well as anyone interested in the debacle of fracking-caused water contamination that may come across this piece. As you are reading, I ask that you keep in mind that this is a very perplexing issue that has not been given much of an opportunity for true research and investigation. Therefore, the data discussed has not been officially proven or disproven to be directly related in every way to local fracking. However, the research gathered on the proposed danger of the Hydraulic Fracturing process is solely based on science that has already been proven as well as documented illnesses and symptoms from residents and contractors around or near fracking operation sites.
Hydraulic Fracturing is a process where high-pressure fracking fluids are forced into rich shale to extract natural resources. These fracking fluids are a mixture of proppants and “chemical additives such as surfactants, biocides, fiction reducers and other compounds meant to help in the process of freeing the trapped gas”. In addition, the million gallons of water injected along with the fracking fluids return as flowback water and this produced water have the “potential to mix with nearby aquifers and surface water”. As a result, there is a considerable amount of public concern about water contamination due to this process of hydrofracking (Thurman, Ferrer, Biotevogel & Borch, 2014).
Fracking has become a highly controversial and publicized topic in recent years due to rising concerns into the potential benefits and consequences of using hydraulic fracturing to retrieve natural gas and oil reserves. With concerns over water pollution, mismanagement of toxic waste and irreversible environmental damage mounting, the practice of fracking has
The most dangerous consequence of fracking is that hundreds of chemicals are blasted into the Earth’s crust, which creates cracks in the bedrock. Many times, these cracks lead to an aquifer, in which case, all of the water in the aquifer becomes contaminated with these chemicals (Jackson, 2014). Additionally, when the natural gas is being pumped out of the wells, methane is released into the atmosphere. A study conducted by NOAA found that approximately 4% of the methane is being released into the atmosphere. This same study found that methane pollution increases climate changes because it traps heat in the atmosphere 25 times more than carbon dioxide (Hoffman, 2016). Furthermore, fracking waste wells are the primary cause of the increase of earthquakes in the Central U.S. This is because these wells operate for a longer period of time, which means that they inject more “solid ‘cake’” into the Earth than the actual fracking process (USGS, n.d. and StateImpact, 2017). Finally, recent studies have found that people who live near a fracking site are at higher risk to develop respiratory problems, which is due to the increased levels of pollutants. These pollutants are not only affecting the people who live in close proximity to these sites, but to the workers, as well. The most common type of respiratory problem reported was lung
In recent years, the subject of hydraulic fracturing, better known as fracking has been a constant subject of interest in the news media. The pros and cons of fracking are passionately debated. However, the public should become educated on the subject of fracking prior to choosing a side of the argument. In the scholarly article, “Super Fracking,” published in 2014, by Donald L. Trucotte, Eldridge M. Moores, and John B. Rundle, a detailed description of fracking is provided, followed by their analysis of current issues surrounding the controversy. According to Trucotte, Moores, and Rundle, fracking saves the consumer money. The wellhead cost to produce natural gas in January of 2000 was two dollars and sixty cents per one thousand cubic feet. At an alarming rate, the cost at the wellhead to produce natural gas had risen to eight dollars per one thousand cubic feet by January of 2006. Comfortingly, the wellhead cost dropped to two dollars and eighty-nine cents by the end of 2012. Impressively, gas production increase and price decrease over the time period are a result of fracking. In their article, Trucotte, Moores, and Rundle describe in great detail that hydraulic fracturing, most commonly referred to as fracking is the process of drilling down into the earth to fracture the layers of rock so that a high-pressure water mixture is directed at the rock to release the oil or natural gas inside. This method of fracking has been used commercially for the last fifty years.
While it is true “fracking”, a procedure to obtain natural gas removal from shale formations, it is also true there have been infrastructure security issues associated with this practice. Furthermore, there have been ecological considerations from fracking brought to the forefront by countless environmentalists. Indeed, hydraulic fracturing, as it is referred to, is a process by which shale gas and oil is uprooted from a depth far below the earth’s exterior. The process of extracting shale gas and oil is employed aggressively while water is forced deep beneath the earth surface through a geological arrangement. From this arrangement, oil and gas is exerted back to the earth’s surface. Moreover, once the hydraulic fracturing process is
Another problem that we know exists with hydraulic fracturing is the contamination of the water, the ground, and the air around the sites (Goldman pg. 2). It has been shown that “…residents living near the hydraulic fracturing sites are increasingly worried that the drilling process might be contaminating their well water, polluting streams, and releasing toxic gases into the air (Hobson).” Water sources, as well as the soil, are often polluted from flowback fluid and from production brine (Hydro-Fracking pg.4). Flowback fluid is “the contaminated fluid that returns to the surface during the drilling process, and is estimated to be between 9% - 35% of the fluids injected during
“Fracking: the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc., so as to force open existing fissures and extract oil or gas”(Google). Ten years ago no one would have thought hydraulic fracturing or “fracking” would have caused such environmental harm; infecting public and private water systems, cutting down national parks, and causing extraneous health problems.
