In the present research, a total number of 17 tap water samples were collected and analyzed for radon concentrations. There are two potential factors that may affect the radon concentration in tap water, which is building age and water sources. The values of radon concentration of tap water samples are listed in Table 1, which represents a comparison between the values of radon concentration with building age factor and water sources factor. The radon concentration in building that built in before the year 2001, after 2001, after 2005 and after 2010 ranged between (30.5±1.2 to 119±2.0) Bq/m3, (6.58±0.6 to 71.0±1.8) Bq/m3, (16.3±0.9 to 65.1±1.8) Bq/m3 and (8.65±0.6 to 44.4±1.4) Bq/m3. It showed that there was a trend in increasing order as building

    A Summary Of Lead Contamination In Flint

    In “Lead Contamination in Flint - An Abject Failure to Protect Public Health” David Bellinger examines the impact Flint’s contaminated water has and will continue to have on its population, primarily the children. In 2014, executives from the Flint Water Treatment Plant decided to use the Flint River as the main source of water instead of Lake Huron as a “cost saving measure.” The river is polluted with lead from older, now defunct industrial factories which specialized in products that contain harmful byproducts. One of the water-purifying agents used in the Flint River is ferric chloride which has an effect on naturally occurring bio-matter in water, increased corrosiveness.…

    The quality of water in this case is inhibited during the Hydraulic Fracturing where chemicals are used to release gas within the formations. These chemicals pose a threat to the quality of water thereby making it impure for consumption by human beings and animals. The chemicals and their concentrations are regarded to be more dangerous since their sources are unknown. The concentration of these chemicals in water causes unbearable symptoms of nausea, respiratory irritation, kidney, liver and heart damage, chemical burns and rashes that affect many…

    Lead-Contaminated Drinking Water Summary

    The article Fetal Death and Reduced Birth Rates Associated with Exposure to Lead-Contaminated Drinking Water by Marc Edwards discusses some incidents regarding lead exposure, along with the correlation between this complication and fetal death, as well as miscarriages. At first glance the observation and claims being shown seem constructed with specific diction concerning a science, more precisely, ecological science. Throughout Edwards’s article, the claims presented are accompanied with the use of charts and notation. When viewing this notion of lexicon, it is suggested that the intended audience should possess knowledge and be familiar with certain vocabulary, as stated in the first sentence, “in children at thresholds >5 μg/dL and also >10 μg/dL” (739). We assume this as Edwards does not further elaborate on his charts and notations, leaving a portion of audience unsure of the truth and meaning behind these claims.…

    Flint Water Problem

    Flint, one of the largest cities in Michigan, has been recently in news for its very high lead concentration in drinking water. The problem started when the city temporarily changed its water source as a cost saving measure. Lead in Flint’s municipal water came from the old lead pipes, which reacted with highly corrosive Flint River water in the absence of proper treatment measures. Lead concentration in Flint water is found to be so high that it can be easily considered as hazardous waste. Although, the residents of Flint were complaining about their water from the very beginning, neither the local and the state government nor the EPA considered that as a problem.…

The reason many people are not lead poisoned despite the fact that most of the pipe use to travel the water are made of lead.

    Water Quality In Raccoon River

    From my understanding, the issue of water quality in Raccoon River is an integrated issue. Who is truly responsible for excess nitrate pollution? As a government the state of Iowa is responsible for enacting policy that would limit the amount of nitrate runoff from underground drainage tiles. The government of Iowa must also be responsible for enforcing policy, or delegate the authority to enforce. Whether it’s a state agency, or the drainage districts, there needs to be a policing authority.…

    Arguments Against Fracking

    There have also been studies that suggest that chemicals used during fracking, such as methanol, formaldehyde, sodium hydroxide etc., are carcinogens 2. When fracking occurs in a specific site, the chance for contamination is low but as the number of sites increase, the chance for contamination increases 4. It is suggested that advanced testing should be used to trace chemicals used in water during fracking to groundwater and determine if there is a correlation 4. It is projected that many shale productions around the country will have an increase in water usage and it is very important to determine if this will be harmful to public health…

    What Is Fracking?

    Fracking has been a controversial topic for many years now and continues to be questioned. There are debates about the definition of fracking and whether the term refers to the entire industrial process or just the underground water blast that fractures the rock after the drilling is finished. One of the concerns about fracking are the flow back water containing a cocktail of chemicals used for many beneficial purposes but often contains radioactive materials and salts from the underground layers. This toxic water must be stored on site and later transported to treatment plants or reused. Another major concern is the idea that water blasts deep underground can directly contaminate drinking water, by creating unexpected pathways for gas or…

    The Importance Of Water Quality In Canada

    The Canadian Drinking Water Guidelines was issued to serve as a guideline for the quality of drinking-water. According to Eggertson (2015), the guideline did catch some of the mines and projects which caused the water quality to fail, but only few provinces specified the reason, such as source water is contaminated, but not relating unrelated projects to the water quality. This shows that the government’s guideline was not useful in terms of finding the true reason of the failing water quality and solving the situation. Another example is in Quebec, where the provincial government had tried to tackle with the water quality for 30 years, in the way of reducing river pollution (Patonine, Hébert, & D’Auteuil-Potvin, 2012). The programs had been only partially successful since they recognized the main source of the pollution was actually agriculture, where they dumped a large amount of phosphorus (P) and nitrogen (N), which lead to the water quality not meeting its standards (Patonine, Hébert, & D’Auteuil-Potvin, 2012).…

    Analysis Of So Much Water So Close To Home

    In his short story “So Much Water So Close to Home,” Raymond Carver criticizes the lack of sensitivity society has in regards to the power imbalances between men and women by depicting domestic discord and a community’s response to violence that specifically targets women. The reader is introduced to gendered modes of experiencing the world since the story is told from the wife’s perspective instead of her husband’s. Carver’s narrative choice to frame the story from the perspective of Claire, places the reader into Claire’s shoes to piece together how small instances create her overall psychological turmoil. Claire’s relationship with Stuart perpetuates the demise of her psychological health since she feels uncomfortable to explicitly…

    What Are The Arguments Against Water Pollution

    The fact that fluoride in polish drinking water is prevalent in many United States households, similar to Arizona events where tap water has been flooded with a high containment of lead that can cause severe health problems. This results because of the amount of fracking and drilling operations currently enacted. Humans can be exposed to the adverse effects by being exposed of water pollution. “results of some animal and epidemiological studies suggest that fluoride demonstrates nephrotoxicity, neurotoxicity, carcinogenicity, genotoxicity, and may adversely affect thyroid function and fertility”( Lewicka 2) to show the range that excessive fluoride exposure has on all organisms. A similar experiment held by “The YRWQM predicted the variations of water quality resulting from agricultural pollution, which flowed into the reservoir with a flood lasting for 12 days in 2009” (Zhang 3) and compared to the information revealed in Lewickas research can be looked upon as the contamination of water with fluoride that damages drinking water for both man and wildlife.…
