Hundreds of chemicals are used during Marcellus Shale drilling; therefore, the process can cause contamination and pollution. According to Marc Levy and Mary Esch, because the Marcellus Shale drills go so far under the ground, the water there has a higher chance of being polluted. According to the article “Methane Gas and Its Removal from Wells in Pennsylvania” methane is a chemical that can contaminate drinking water because of drilling. Too much methane can be harmful to humans (Swistock and Rizzo). According to the article “Hydrofracking,” water sources also have an increased risk of being polluted when a drill is installed near them.
When water that is contaminated by chemicals is consumed by humans it can lead to sickness, paralysis or even death depending on the kind of chemical polluting the water and the concentration of the pollutant in the water. The Flint Crisis is an example of the damaging effect of chemical runoff, as the Flint communities ' water was contaminated by the lead pipes that carried the water resulting people in the affected communities ending up with lead poisoning. The environment and the animals are also impacted by chemical and radioactive runoff, increasing the death of organisms and decreasing biodiversity(3). Oil runoff water pollution is yet another example of water pollution. The effects oil runoff has on the environment are especially debilitating.
Also, recovery leads to discolored local creeks and rivers because of the acidic run-off of these waters (Lecture 3/11/02). Next, these resources must be transported all over the world, where they will go into the preparation and refining stage. During this stage, there is a risk that refuse or sludge will result from coal cleaning parts (Lecture 3/11/02). Also, air and water pollution may result from the process of petroleum refining, which involves the change of the chemical composition of petroleum to produce desirable chemicals and fuels. However, that means that the undesirable results are released to pollute the atmosphere.
Secondly, fracking results in water pollution, which affects the quality and quantity of water. An article by the Scottish Government (2014) states 25-75% of the fracking fluid returns to the surface as waste-water. This wastewater combines with salty water containing contaminants, forming a mixture of toxic and radioactive substances which could put people at risk of sickness, if this leaked into drinking water. It also reduces the amount of fresh water available for essential daily needs. In conclusion, fracking contributes to water shortage globally as it uses up such a large quantity of water
Fish, plants, water and other organisms are living in our ecosystems. This type of pollution is not only harming them now, but will continue to harm them in the future. There are many ways how water pollution is harming our ecosystem, whether it is oil spills, marine dumping, nuclear waste, or atmospheric pollution, it is all harming water. Underground storage leakages play a role, yes, they are useful in many ways, but they are also very harmful. “Over time the steel corrodes and causes leakages, affecting soil and groundwater” (“Underground Storage Leakages” 1).
According to Sharma (2005), water pollution is alteration in physical, chemical and biological characteristics of water which may cause harmful effects on human and aquatic biota. Industrial waste, oil leakage and chemical and pesticides are some of the sources of water pollution. Industries produce a large amount of waste that contains toxic chemicals. Most of the industries do not have proper waste management system and the waste goes into drain and later into sea. It leads to the increasing of temperature and mineral amounts in water.
Hydraulic fracking poses a huge threat to the environment in many ways. The pressurized liquids come in close proximity to drinking water, potentially contaminating it. In addition, dangerous chemicals are released into the air after the fracking process. Also, the excess water from each fracking site is transported by truck to be disposed of. This adds to pollution and increases potential chances of leakage.
This substance can vary and can highly increase the cycles inability to offer safe habitation to organisms and can even diminish clean drinking water for humans as well. The most common sources of water pollution include both point and non-point. For example, a point source refers to pollutants that can be traced back to a single source such as factories or oil spills. Whereas, a non-point source refers to pollutants that originates from pollutants emitted by multiple sources that are unable to be traced back such storm water runoff or even vehicles emitting pollution into the air. There are many indirect and direct causes that can negatively affect water quality all around the world, including turbidity, physical, and chemical agents that can lead to the destruction of the various significant freshwater ecosystems.
lead channels), high surrounding air fixations close to emission sources, or through food chain. Heavy metals are unsafe on the grounds that they have a tendency of bioaccumulation. Bioaccumulation implies an increment in the convergence of a substance in a biotic organism overtime contrasted with chemical concentrations in the environment. Mixes gather in living things at whatever time they are consumed and saved speedier than they are broken down (metabolized) or discharged. Through industrial and consumer waste, heavy metals can enter a water supply or even from acidic rain breaking down soils and discharging heavy metals into streams, lakes, waterways, and groundwater.
Water from nearby areas has shown to display anti-estrogenic and androgenic properties that can impact endocrine function. Direct exposure of some of these fracking liquids to workers caused gastrointestinal, dermatological and neurological problems. Moreover, there are a host of environmental issues such as noise and air pollution and an increase in seismic activities. Certain countries have gone as far as to temporarily ban or suspend the use of this method. In my investigation, I will attempt to analyse the exact risks that are posed by fracking and what aspect of the technique contributes most to these problems.
