Even biodegradable pollutants can damage a water supply for long periods and the life forms within the water start to suffer damage due to pollution. Lakes are particularly susceptible to pollution because they cannot cleanse themselves as rapidly as rivers or oceans. In recent years, waste treatment plants have developed ways to deal with water contamination. Some places, however, still pollute streams by allowing raw sewage to run into them. Septic tanks and cesspools may also pollute the groundwater and neighboring streams.
Hydraulic fracturing is a dangerous procedure to those who live around it, so regulations on fracking should be more strict. First of all, the process of fracking is found to contaminate tap water. According a Yale study on fracking, there have been numerous reports by citizens across the country of fouled tap water. Some of the tap water has even turned bubbly and flammable, which means there is an amount of increased methane. Also, it was found that the companies involved cannot be trusted, and roughly one in five chemicals involved in the fracking process are still classified as trade secrets.
My argument is deductive because I say it the waste fluids pose a threat on humans and I will have more specific information of how it really affects humans. The type of argument is Modus Ponens because it affirms the antecedent.

People who live near the wells are at a high risk of getting cancer because of the chemicals that are spilled into the air. Even though when people talk about fracking mostly all think about how it contaminates water, but the big thing to worry about is the air that is being polluted.
INTODUCTION 1.0 Background of Study Nowadays industrial sector has grown increasingly higher thus produce more waste material that need to be drain out to the environment. Most of this waste contains a lot of chemicals that are dangerous to human and may corrupt the biodiversity of our ecosystem. Heavy metals in industrial waste are one of the problem encounter today as one of a serious matter that need attention to. Due to rapid industriallisation, heavy metals have been excessively released into the environment, with remarkable impact on humans and other organism. Cadmium, zinc, copper, nickel, lead, mercury, and chromium are often detected in industrial wastewater, causing an obvious or potential threat to water quality, human health and biodiversity in the ecosystem(Huidong et al.,2008).
In addition to water from lakes and rivers, groundwater can also be contaminated. Groundwater contamination can originate from several sources. First of all, groundwater can be contaminated by gas leaks from storage tanks, which have chemicals such as oil). In addition, toxic leaks from landfill sites and leaks of industrial chemicals from manufacturing sites can also cause groundwater contamination, as chemicals can leak into the groundwater if they are not managed properly. Bacteria can also contaminate the groundwater when fertilizers, pesticides, and septic tanks leak.
Marcellus Shale drilling is a hazard because it uses hundreds of dangerous chemicals in its process, it can lead to pollution and contamination, and it has few regulations applied to it; although, a solution to the major issues of this drilling is to create and enforce more regulations. Marcellus Shale drilling causes a problem because it involves the use of hundreds of deadly chemicals. Over three hundred chemicals are used in the Marcellus Shale drilling process (Environmental). As stated by Howells, author of the article “Don’t Frack with Our Water!”, these chemicals are especially dangerous because the companies that use them will not tell the public what specific chemicals are being used. However, through studies of the chemicals, some of them can be identified.
Most of the heavy metals are toxic or carcinogenic in nature and pose a threat to human health and the environment (Shakibaie et al., 2008; Vinodhini and Narayanan, 2009). Several conventional methods are used for the removal Heavy metals from wastewater includes chemical precipitation, ion exchange and reverse osmosis etc. but major drawbacks with such treatments are produces large amount of sludge and may be ineffective or expensive processes. So, the search for a new, simple, effective and ecofriendly technology involving the removal of toxic heavy metal from wastewater has directed attention towards phytoremediaton( Divya Singh et al., 2012).According to UNEPPhytoremediation can be defined as “the efficient use of plants to remove, detoxify or immobilise environmental contaminants in a growth matrix (soil, water or sediments) through the natural biological, chemical or physical activities and processes of the plants”. The ideal plants for phytoremediation should possess the ability to tolerate and accumulate high levels of heavy metals in their harvestable parts, while producing high biomass.
Along with drilling, explosions and toxic chemicals may be used. There are millions of gallons of water pumped into the crevices created by these methods to further help. This water becomes polluted by the oil and can seep into the groundwater. This may lead to the pollution of an entire town’s drinking water. The gas wells used may also explode from the pressure, which also would pollute the groundwater (Homme... ... middle of paper ... ...on is a helpful element but, emphasis should be on prevention, rather than just treating the problem.
Hydraulic fracturing, or fracking, was once considered a great way to get clean energy. It was considered much safer for the earth compared to coal mining and had support from big environmental organizations such as the Sierra Club. However, some issues have come up that put into question the actual effects that fracking has on the environment. Besides the noise and air pollution created by the drilling of wells and the truck traffic on the fracking sites, water pollution has become the greatest concern. When done incorrectly, fracking can load the water supply with thousands of dangerous chemicals and make it unsafe for drinking and other uses (Shan).
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.
