Coal seam gas (CSG) is mostly composed of methane and is typically attached to coal underground. This gas is released when pressure on the coal seam is reduced by removing water from the seams (Queensland Government, 2014 ). In order to obtain the gas, wells are drilled into the coal seams, bringing water from the coal seams to the surface. This process reduces pressure and allows the gas to be released (Queensland Government, 2014 ). CSG is an important energy resource in Queensland and production of this gas takes up an ever-increasing proportion of Queensland gas use. Almost every farmer in Queensland depends at times on underground water. The effect of CSG extraction using underground fracturing on underground water is not clear. Basic sets of impacts that are broadly well understood are that aquifer levels will sink dramatically and will depressurise. It also risks groundwater contamination and the salt that is present in the water of coal seams will be brought to the surface as well, in a quantity of about 1.8 million tonnes of salt per year (ABC, 2010). There are several types of water contamination that are possible. One is through the injection of chemicals through the fracking processes, which will go underground and can travel to nearby water systems that are in use (Gasfield Free Northern Rivers, 2014). Another is through chemicals that naturally exist in coal seams being taken out of the coal seams and exposed to other the various water systems nearby. Some of
I would have to say that from the reading that it can be very harmful for the coal mining chemicals to seep into the ground into our drinking water.
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
Few issues have recently gotten as much attention as the energy extraction activities involving a controversial procedure called "fracking." As reports of drinking water becoming tainted with fracking fluid flood the news, both oil and gas companies as well as environmental groups are presenting competing "facts" about the effects of drilling on ground water.
Coal-bed methane is naturally occurring methane with some amounts of hydrocarbon gas as well as non-hydrocarbon gas that is contained in coal seams resulting from chemical
Do you feel that your leaders ever fail to use their authority in the way you believe they should? James Madison believes that government is power, and since humans are in charge of the right, it always has the ability of being misused. Communities revert to chaos when the authority figures abuse the influence they have. Madison’s argument is correct because people in general need strong rulers, so if the privilege given to the superiors is exploited, society begins to break down.
The greatest common concern on the subject today is water contamination. Individuals grew worried that the chemicals used to gather these natural resources will seep into the water and contaminate the United States. The water necessary to frack is gathered from rivers, lakes, ponds, and even aquifers. This is then combined with chemicals and pumped into the ground. Fracking was exempted from the Federal Safe Drinking Water Act and the chemicals used to frack are not tested frequently in our water (Lampe 34). Bordering on 20 to 40 percent of the water used to frack rises back up to the surface and is stored on site (Lampe 34). An
The west was swept by enormous change after the civil war. There was a lot of mining that was started because gold and silver was discovered and when people heard about it, many people poured into an area that was ill prepared for their arrival.
Stephen holditch of the department of petroleum engineering, Texas A&M University believe that hydraulic fracking does not cause pollution and has not contaminated any water in any known cases when fracking was used in wells; however there have been many cases of this and could cause a more serious problem if it continues. ‘The oil and natural gas industry support more than 2.1 million jobs according to IHS. Economics” (source 8). ‘Other policy experts say hydraulic fracturing could supply more than half of U.S. natural-gas production by 2030” (source 5). With this being said if we stop hydraulic fracturing we could have millions of people lose jobs and would have a great energy shortage. Though if Hydraulic fracturing continues, climate change could speed up, lots of ground water sources could be polluted and some of the ‘650 chemicals that can cause cancer” (source 3) could spread and there could be a cancer epidemic. Going back to loosing ground water sources, it was found that ‘scientist discovered methane in 115 out of 141 shallow drinking-water wells. It [was also] found the closer the water source was to the natural gas well, the more methane it contained.” (source 4) taking this information in there are also other ways to generate power such as solar farms and hydraulic
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
The mismanagement of the practice has the potential to create environmental damage such as water contamination, radioactive spills, and increased seismic activity that could cost thousands in dollars in damage. Furthermore, the unintended consequences of fracking can have detrimental effects on the environmental. The potential for water contamination can pose both an immediate and long term risk to environmental stability, including landscape distortion, inhabitability and ecological displacement. This contamination of drinking water can also be detrimental to the human environment, limiting the amount of safe water available for both the residential and commercial human environment. With the increase of fracking, the level of disapproval for the practice has only mounted. Concerns including overconsumption of
“DEC 's own review identified dozens of potential significant adverse impacts of (fracking)” (Krisberg 18). There are some potential impacts in the fracking process, it will bring a lot of health risks to people. The major constituents of produced water are salt content, oil and grease, various inorganic and organic chemicals, and naturally occurring radioactive material. Salt content in produced water makes the freshwater to salt levels up higher than seawater. Oil and grease makes freshwater is getting oily. Various inorganic and organic chemicals are found naturally in the formation or are chemical additives used during drilling and operation of the well, such as benzene and methane. “Many of the fracking additives are toxic, carcinogenic or mutagenic” (Howarth, Ingraffea 272). This quote tells us that why fracking is contaminating the drinking water. Benzene are one major concern. “The state of Texas reports benzene concentrations in air in the Barnett shale area that sometimes exceed acute toxicity standards” (Howarth, Ingraffea 273). It shows benzene makes drinking water is getting contaminated. “Methane contamination of drinking water reservoirs has been documented in fracking-rich areas of the US. Leading to dramatic videos of seemingly ignitable tap water” (Benusic, 238). This quote tells us that the drinking water is getting contaminated by Methane is proved already. Radioactive material in
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
Since the start of our country, America has been known as a land of immigrants, a melting pot of different cultures and ethnicities working towards the American motto of the land of the free, home of the brave. Since colonial times, immigrants have been an integral part of society, majorly contributing to U.S culture and economy, yet many Americans have always had very conflicting ideas on immigration. Many people look past the benefits immigrants bring to our economy and society and instead scapegoat them for many of the United States’ problems surrounding unemployment and budget. The positive effects of immigrants, both legal and undocumented, in our country far outweighs the negative effects because of their important impact on society and the economic help that American relies on.

As Australia’s energy demands rise along with a rising population it is likely that fossil fuel consumption will also rise despite concerns about climate change. This energy demand as well as government debt has seen the start of hydraulic fracturing in Queensland. The development of coal seam gas is to create thousands of jobs while providing a boost to the state’s economy. Many Australian landowners are allowing the fracking on their properties because they will receive income from the well (De Rijke 2013). The decision of the government to commence fracking has been opposed by the wider public. Local governments are virtually powerless to stop fracking as this power lies with the Australian state and
