Contamination of Water Essay

Method of pathogen introduction to a non-pathogenic environment includes brood stock, Aquaculture feeds and equipment. But the main method of disease introduction is due to movement of contaminated animals. Assessing of the antimicrobial use is a difficult task due to more than 200 aquatic species are

In his book, An Economic Interpretation of the Constitution of the United States (1913), he supposed that the Constitution was an elaborate ploy to support the economic superiority of the Federalists. His reasoning behind this was due to his observation of the Founding Fathers, for he realized the three leading authors were all Federalists. These three men, like several other Federalists, were members of the upper class; a social class of land owning white men. This exemplifies why Beard would believe that the Constitution was created due to greed. The Federalists that created the Constitution were elites who simply wanted more money, more power, and more land to their names. According to the Progressive Historians, this amount of power came at a cost for the Anti-Federalists. They thought the Federalists would steal power away from the state, and with it the power of the common people. Although Beard and the Progressive Historians are correct to an extent, the principle of Federalism counters these

Flint in Michigan is located 70 Miles away from the shores of large fresh water bodies, the Great Lakes. Despite this close proximity to the fresh water bodies, the residents have not been able to get the clean water. The water supply of Flint in Michigan in the United States has undergone serious water contamination crisis. The water crisis started in April 2014 (Massachusetts Water Resources Authority, 2016). The contamination of drinking water began when the source of water was changed from the treated Detroit Water and Sewerage Department to the Flint River. This later led to a serious contamination of the water due to lead contamination hence creating more danger in the public health. The Flint River had a corrosive nature and caused lead from the old pipes to leach into the water supply. This caused heavy metals in the water supply. This posed serious health problems. For example, six thousand to twelve thousand children were exposed to the contaminated water. The blood-lead level in children increased. The alteration in the water source was the main reason behind the water crisis in Flint.

The results of the experiment supported the aim by identifying whether or not microorganisms found in dam water were disease- causing pathogens. The pathogens that were identified are opportunistic and can cause disease to the host by interrupting normal bodily functions.

Water contamination in America has been caused by numerous things that we do on the everyday Bases before we rest around evening time. For instance Driving, Placing oil in the auto , tossing unfilled jug, manufacturing plants that work regular in morning the significant reason for contamination to america soil, there are 43 thousand of plant in america that work ordinary and evenings.Without sound water for drinking, cooking, angling, and cultivating, humankind would die. Clean water is additionally fundamental for recreational interests, for example, swimming, drifting, and water skiing. However, when Congress started surveying national water quality amid the mid 1970s, it found that a great part of the nation's groundwater and surface water

Methods: In this experiment, results were found by discovering the kinds of bacteria found in the given pond water samples. The first step in this experiment was to prepare the pond samples by completing serial dilutions of the pond water to the 10-4. We then had to prepare five separate plates by streaking the 10-4 dilutes. These plates all had different treatments. The treatments were pond 16, pond 22, pond 22 with penicillin, pond 22 with ampicillin, and pond 22 with colistin sulfate. The plates that were treated with antibiotics required 0.1 mL of the designated

Flood waters contain high levels of bacteria. (2) (The samples taken for the experiments include creek water. This means that the creek water samples should have a high percentage of bacterial colonies.) Bacterial contamination cannot be detected by smell, taste or sight. The only way to see if the water supply contains bacteria is to have it tested.

My lab report was based on how ground water could be affected by contaminants that surround us everyday. “ Access to safe drinking water depends not only on the quality of water at source but also on contamination throughout it's way to the user and practices related to purification and sanitation” ( Mishra, S., & Nandeshwar, S. 2013).I was very surprised that the detergent contaminated the water. I thought that the detergent would stay in the soil but it ended up going through the soil into the water. Which then left the water bubbly and dark. These labs may show that we may need to look into more

Ciprofloxacin is a fluorinated antibiotic which is used to treat different types of bacterial infections. There is significant concern that antibiotics and hormonal based medications particularly those found in the pill are effecting the breeding cycles of animals, in particular in the oceans. These chemicals are found in domestic waste and pass through waste water treatment facilities (WWTF) into the water ways. This experiment determined the ciprofloxacin concentration in the sea water at three locations in major city (See map below, red dots indicate locations, red arrow

To develop a better understanding of water contamination, a field comparison between two separate water sources was conducted. The first water sample was gathered from the Simmons Park Pond and the second from a NES water fountain. The data gathered from this experiment was used to answer several questions regarding the prevalence of contamination in nearby water sources. The field analysis ultimately concluded what contaminants had the greatest prevalence, thereby exemplifying the defining differences between the two water sources.

That is why it is of the utmost important to check the effectiveness of a hiker’s equipment. Water purification is the most important thing to have while out hiking in the backcountry. A real world scenario was the only way of being able to properly tell whether or not the Iodine tablets could be counted upon, when they are the only thing being used for water remediation. The lab procedure start by taking a river water sample from the Menomonee River, which was then separated into three 1L beakers which were then filled to the range of .95L to 1L. The water samples as is, were then swabbed for bacteria, and rubbed across a Tryptic Soy Agar plate (TSA), to facilitate growth of bacteria if any was present in the water. The water was then treated with the drinking water tablets per their instructions, and was then swabbed again for bacteria after the 35 minute mark. This second swab was then also streaked across a TSA plate in order to check if there was any bacteria still present in the water. The previous methods were also performed concurrently with three identical amounts of water from the city of Milwaukee tap water. This was done to account for any bacteria that could have entered the water from the air, due to the open air beakers. The bacteria, if present on the TSA plates, were then allowed to grow over several days, and the resulting bacteria colonies were then counted, and purification levels were compared between the drinking water tablets and the treated city

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

Domestic wells are usually shallower than public wells and are more susceptible to contamination from surface waters (Kumar et al., 2010). From 1971-2008, private wells were responsible for 67 percent (n=40) of reported outbreaks from groundwater (Wallender et al., 2013). Contamination of the groundwater that feeds drinking water wells results from infiltration from rivers, septic tank leach fields, and leaking sewer lines (all sewer lines leak). Cross contamination with septic system wastes due to poor design, maintenance or improper spacing is listed as the primary cause. Contamination of groundwater is reportedly widespread (Auld et al., 2004; Curriero et al., 2001; Fong et al., 2007; Thomas et al., 2006; Tornevi et al., 2015) and

This study was done to determine unknown microorganisms that were retrieved from pond water in Rocklin, California. If the study involves identifying microorganisms from water, various amount of test are done to find what type of bacterias are in water. The most common bacteria in the genera Eschericha, Pseudomonas, Acinteobacter, and Aeromons are amongst the top bacteria found in water. As a result, one or more of these microorganism will be found in the pond water collected. It is important to specify one of these bacteria in the water sample as it is potentially harmful. Some strains of Eschericha Coli are known to cause “serve gastrointestinal infection, dysentry and even death in susceptible individuals”(Wilson, 2015). Most importantly, it is important to find these species that can cause danger to humans. So, they can be treated accordantly with the right antibiotics if they presented any of the side effects.

Freshwater sources are open to vulnerabilities, such as pollution from the environment and the presence of bacteria. Because the Koi Pond is out in an external environment, it was reasonable to assume that contaminants and bacteria could enter the water source. As mentioned in the results section, the Koi Pond was the only water sample that exhibited E. coli; the hypothesis was supported by the lab results. The Koi Pond water sample looked identically to the other types of water samples; however, it would be wrong to assume that just because the samples had similar appearance, they were also similar in quality. For instance, the Deer Park water sample was also clear, but it had no presence of E. coli. Furthermore, the aquarium water sample
