During the process in which the fracking solution is forced into the ground at high pressures, occasionally toxic fluids can leak out from the system and contaminate nearby drinking water. Environmental studies have concluded that methane concentrations are seventeen times higher in drinking water wells near fracturing sites. There are at least 1,000 documented cases of water contamination next to fracking areas as well as cases of sensory, respiratory, and neurological damage due to ingested contaminated water. Up to six hundred chemicals are used in the fluid solution they send into the ground, including carcinogens and toxins such as uranium, methanol, mercury, hydrolic acid, ethylene, glycol, and formaldehyde. When they bring the fracturing fluid back up after fracturing the shale rocks, to release the natural gas, only thirty to fifty percent of it is recovered. The waste solution recovered is then left in open air pits to evaporate, releasing harmful VOC’s (volatile…
They are concerned that millions of gallons of contaminated wastewater are produced from fracking methods and that there are currently no facilities operating to remove these pollutants. When separated by a mile or more from groundwater sources and the earth’s surface, the ancient marine waters along with naturally existing toxic compounds are not an issue, but “Fracking disturbs, distributes, and carries upward with the fracked gas ‘produced waters’ containing radioactive materials, heavy metals, hydrocarbons such as BTEX (benzene, toluene, ethyl benzene, and toluene [sic.]), bromide, highly concentrated salts, and many other organic and inorganic compounds that, when exposed to our environment, are dangerous health hazards—many are known as carcinogens and toxic to biological life” (Carluccio “Destroying Our Groundwater” Para. 1). Which brings up the question of why can’t they use less toxic chemicals in the fracking process? Tracy Carluccio, the Deputy Director of the Delaware Riverkeeper Network, continues by stating, “even if companies were to switch to ‘green’, ‘non-toxic’ fracking fluids, drilling and fracking in these deep formations will always deliver potentially deadly chemical hazards, even in a perfectly regulated world” (Carluccio “Destroying Our Groundwater” Para. 1). The cement and steel casings used in combination with the methods for sealing post-production gas wells do not confine the methane along with other dangerous gases and contaminated fluids that are pressurized within the aquifer.…
Hydraulic fracturing, otherwise known as fracking, is a 60 year old practice of pumping high pressure water into shale rock thousands of feet below the earth’s surface. The pressurized water is pumped through cement encased pipes at pressures reaching 9000 pounds per square inch. The treated water is forced into small cracks in the gas-rich shale rock, resulting in the breaking of the rock and the release of natural gas that would otherwise be unobtainable. Hydraulic fracturing is a safe, economically efficient way to drill for natural gas, create jobs, and lessen America’s dependency on foreign oil.…
Hydraulic Fracturing or fracking was first introduced in 1940s and has then been a key provider of natural gas and oil worldwide. Despite its expansion and customary use, fracking still poses many health and environmental concerns. During fracking, pressurized liquids are injected into drilled wells, which cause the surrounding rock to crack open allowing gas and oil flow through the fissures. Millions of gallons of water are used and a similarly large volume of waste water is generated. Most of the water is never restored and the stored waste water and fracking fluid can adversely affect the animals and vegetation around it. Along with the water, other chemicals are injected into the ground as far as 10,000 feet below the surface and enter groundwater, polluting drinking sources for many. Fracking may be a key provider of oil but this expensive, polluting, low energy-return process is not worth the loss of wildlife habitat, natural land and innumerable water resources.…
Fracking, also known as, hydraulic fracturing is the idea of using hydraulic pumps mixed with water, sand, and chemicals to break rocks apart at high pressures which then will release gasses. The chemicals used are not really known, but are said to be extremely hazardous to people, animals, and etc. The pumps on these machines use water from creeks as a water source. The sand that is used, is removed from the bottom of a local creek bed or can be manually added into the mixture. By removing it from a local creek bed, this could endanger local species that call the creek bed home.…
Fracking requires up to 5 million gallons of water per well and perhaps even more in which case, the tons of water used would create a huge demand of local water supplies (Dong). Unlike agriculture or domestic water uses, gas drilling does not return the used water back into in the ground (Myers). The water can not go back into the ground because the returned water not only has added chemicals that helped with fracturing but also has about 40,000 gallons of chemicals that were previously added (Dong). Sometimes, the used water can leak out in surrounding lakes and rivers. Those lakes and rivers supply the surrounding communities with water but now since fracking, the water is polluted. The chemicals that are in the water can cause serious illnesses and possibly be life threatening since most chemicals are poisonous.…
In addition to the need for large quantities of water needed to do a frack job, it is controversial. In rare cases, when proper cementing procedures are not followed, frac fluid, which is a mixture of water and chemicals such as acids, can migrate or be forced into groundwater. (Baker, 2001) In most situations, the groundwater lies from zero to one thousand feet deep, while the natural gas bearing formation lies at several thousand feet. In the case of the Marcellus Shale the gas is not that far in the ground, so to extract the gas the people fracking will be in danger of contaminating the groundwater. In New York the issue has raised particular concern because part of the Marcellus Shale lies underneath the city’s drinking water supply, not to mention the contiguous forests of the Catskill Mountains and many upstate counties. Aside from the chemicals used, the building of roads, heavy truck traffic, the installation of drill pads, and the massive…
This paper explores the hydraulic fracturing process, exactly what it is, what the fracturing process does to the earth and the surrounding environment in addition, to the consequences. Hydraulic fracturing is fracturing of rock by pressurization. This process by which oil and natural gas can be forced from the earth. The hydraulic fracturing process takes millions of gallons of clean water, sand, chemicals and pumps them underground at high pressure to break apart rock to release gas and or oil. My research has led me to the discovery that there are as many proponents for fracking as that are those that oppose the process. One thing no-one can deny or easily hide is that once the damage is done and something has gone wrong, the evidence usually speaks volumes that this is not something we should be doing to our planet or its people. The diagram on page 3 outlines the process defined as fracking for an easier understanding of how invasive the process is to the environment.…
Fracking is the process of drilling and injecting fracking fluid into the ground at high pressures in order to fracture shale rocks to release natural gas. The fracking procedure is different than the usual oil technique used to get oil. First, they drill vertically into the ground. After drilling, they inject chemicals, water and sand into the well. When the shale rock is finally cracked they begin extracting the natural gas. There are more than 500,000 active natural gas wells in the U.S. (Dangers of Fracking). The materials required at a fracking site are large amounts of water and sand. A fracking site needs one to eight million gallons of water and about four million pounds of sand (Dangers of Fracking). The graph below shows the process of how fracking is done.…
Hydraulic fracturing, also termed hydrofracturing, hydrofracking, or simply fracking, is hotly debated for its economic and environmental impacts. Fracking is the process by which rock is fractured by a pressurized fluid containing water. chemicals and sand to access natural gas, petroleum and brine from great depths of the Earth’s surface. Fracking produces the economic benefit of more accessible hydrocarbons, not to mention the 2.5 million fracking related jobs that were recorded in 2012 worldwide, one million of which were in the United States alone (FracFocus: ECHO-EPA Violations). However, many fear the environmental effects. Risks include ground and surface water contamination, air and noise pollution, and an increase in seismic activity. Hazards to public health and the environment are yet to be discovered, because the first commercial application did not begin until the late 1940’s; however, hydraulic fractures have been recorded naturally throughout time (The Truth about…
While fracking accidents are mostly harming the animals, fracking also pollutes the water, consequently people are noticing a huge change in water quality. Fracking contaminates the water in a very obvious way. Fracking could had been done only using water and clean sand. However to make the job easier and cheaper, the process includes many other 596 or more chemicals, many were harmful and some were unknown. Even though the fluid used in the process is pumped out after doing its job, it's impossible to get it all out. People found black grease, odors, methane, a gassy taste, and black sediments in their drinking water after the…
Hydraulic fracturing is a 21st century method applied to extract gas from the rock bed in the Earth’s crust. It is commonly referred to as ‘fracking’. The process is carried out by breaking apart the rocks by the addition millions of gallons of water, sand and chemicals preceded by the explosion of the rock bed. It is most commonly practiced in the United States; this technique hasn’t been applied in other countries a lot. It is predicted that this would be a solution the ever rising prices of oil and natural gas due to abundance of potential shale gas reserves. Hydraulic fracturing is not a method used for extraction of conventional natural gas.…
Fracking occurs when “water wells become plugged up with sand and other minerals. A machine is brought in to inject water into the well at extreme pressure to blow out the tiny cracks and fissures in the rock through which the water flow.” (Fracking Threatens Everyone) Completely harmless. Or so it seemed at that time. Today dealing with increased pollution, it contaminated this ‘wonderful’ thing. “Fracking injects large quantities of water under great pressure with sand and many toxic chemicals mixed in. Many of these are can cause cancer…Unfortunately, when fracking goes wrong, sources of drinking water ca be ruined and all different types of pollution can happen in a second.” (Fracking Threatens Everyone) Just like that, in a blink of an eye, something wonderful was turned around and causes more problems than we can…
Water is one of our important resources that were given to us by mother nature. We see water as a source for survival and many more advantages. It's fragile, and the smallest amount of contaminants could ruin it for a population, yet one of the major ingredients in fracking processes is the water. Reports of accidents involving water contamination are everywhere. The basic process of fracking is its uses of incredible amounts of gallons of water per drill and drilling so close to groundwater sources risk contamination. "Accidents have already been documented and citizen's well waters have been tainted with toxic chemicals", according to the Climate Progress. (Foster) Many of the chemicals used in the fracking process are proven toxins. These include benzene, ethyl-benzene, toluene, xylene, naphthalene, and other hazardous chemicals that are harmful if any contact is made.…
Fracking causes water and soil contamination. Every fracking job requires 1 to 8 million gallons of water. With this massive requirement of resources comes a…
