"DESALINATION OF DRINKING WATER IN FLORIDA
Water Supply Problems That Compel Desalination Generally.
Around the world, primarily in heavily populated zones of the temperate climes, available fresh water sources for municipal-scale, public water supplies have become overtaxed. Either there are shortages, net of demand, or water has been reused so many times that the remaining resource is saltier than is healthy for beasts, plants, or people. At the same time, accumulated brine and even abundant sea water remain available, even inexhaustible, if only desalting technologies can be applied feasibly. Even where fresh water is available, moreover, some commercial processes or machinery require waters of very low dissolved solids contents, such as soft-drink or medicine manufacture or industrial boilers or cooling towers. For these ..."

Abstract
The paper looks at the three main mechanical processes of desalination commonly used today: electrodialysis reversal, thermal desalination and reverse osmosis. The paper discusses how the preexisting water supply was not enough for Perth, Australia to handle all the new people moving to the city. The paper describes how Perth began using the desalination process of reverse osmosis to treat its seawater. The paper examines the problems of costs and energy sources as well as their solutions. The paper concludes that Perth's new reverse osmosis plant has proven to other parts of the world that desalination can be a clean, efficient and cost-effective process.
From the Paper
"Desalination is a mechanical process by which saltwater from oceans can be converted into drinking water for human consumption by removing the salt. There are three main mechanical processes of desalination commonly used today; electrodialysis reversal, thermal desalination, and reverse osmosis.
"Electrodialysis reversal is the most intricate and cost effective desalination system of the three commonly used processes. Electricity is used to ionicly charge the salt in the seawater molecules, and then it is passed through an ion permeable membrane filtering the charged salt molecules. On the other side of the membrane, the water is clean and safe to drink. This process is problematic because of its extensive use of electricity, which is expensive and sometimes unavailable."

Abstract
This paper is a literature review of the feasibility of desalination plants in New South Wales. The paper also explores the environmental, economic and social impact of desalination plants as well as offering some practical steps that can be taken to mitigate environmental degradation courtesy of these facilities. Finally, the paper concludes with some alternatives to desalination facilities that might just work.
From the Paper
"In recent years, the feasibility of establishing desalination plants in Australia has become a topic of much debate. The following paper will review the available literature on this subject and attempt also to shed some light on a matter that is often poorly understood by the average citizen. In particular, the paper will evaluate the feasibility of desalination plants in Australia and contemplate the long-term impact of these facilities upon the Australian environment, economy and Australian society. Moreover, the paper will look at how negative environmental factors arising from the creation of desalination plants in Australia (especially in New South Wales) can be mitigated; just as importantly, the following paper will explore whether practicable alternatives are available that might make the construction of these plants unnecessary."

Desalinization, 2005.
The paper discusses desalinization as a means of meeting the world demand for water.
2,475 words (approx. 9.9 pages), 8 sources, $ 97.95
»
Click here to show/hide summary
Abstract
This paper examines desalinization as a process of removing salt from sea water so that it can be used for drinking, watering crops or industrial processes. The author points out that, because water is so important to the very existence of life, the methods used in its allocation and distribution can't be ignored. The paper looks at two methods of desalinization.
From the Paper
"Water is a very valuable resource. Water is essential for every organism on the planet in one form or another. Human's are no exception to this rule. For example Stephen Brooks and Lydia Milijan in Water Policy say, Water is essential for human life. We require water to sustain our lives, and about 83 per cent of our blood is water. Water helps digest our food, take in oxygen, transport body wastes, and control body temperature (Brooks and Milijan 262). The fact that water is so important to the very existence of life means that the methods used in its allocation and distribution can't be ignored."

Abstract
This paper explains that ballast water brings along plants, animals, bacteria, and pathogens that have the potential to become aquatic nuisance species (ANS). The author points out that the Clean Water Act (CWA) of the U.S. protects the waters from chemical dumping, but does not regulate ballast waters. The paper relates that only 20 percent of the people residing in the U.S. are aware of the serious threats that ballast water poses to the marine ecosystem.
Table of Contents

From the Paper
"One predatory fish species could seriously harm the local ecosystem. The introduction of the Zebra mussels into the Great Lakes in USA has infested over 40% of internal waterways. It has already cost the United States of America $ 5 billion, a phenomenal amount. Moreover, even after spending this amount there is no solution in sight as to how they can be eradicated or even contained."

Abstract
In this essay, the writer looks at the articles "Water Is a Human Right" by the Council of Canadians' Blue Planet Project and "Water Wars: Bottling up the World's Supply of H2O" by Joshua Ortega. The writer notes that the two articles share a common theme: that the privatization of drinking water resources is harmful and dangerous. The writer discusses that authors differ, however in how they appeal to readers, the techniques employed to create common ground with their audience, the political/economic philosophy employed and solutions suggested.
From the Paper
"Ortega also uses an analogy between the oil crisis and an impending water crisis. He attempts to frighten readers that future wars over water will be far worse than today's over oil. He refers to the scandal-ridden former energy corporation Enron several times. Neither author acknowledges opposing points of view. It could be suggested that governments can regulate privatized water companies or that competition among such companies could lead to more and cheaper water - the idea behind free market capitalism.
"The authors differ in the techniques used to promote reader action. Ortega suggests a set of primarily feel good options for American consumers - all within the context of America's democratic process. The C.C. speaks to what organizations can achieve than what individuals can do."

Abstract
In this article, the writer discusses that the availability of potable water is a growing political, economic and humanitarian crisis facing many nations of the Middle East. The writer notes that the scarcity of water has become a political bargaining chip and source of conflict among many Middle East nations for years, and numerous threats could inflame this contentious issue. For example, the population of the Middle East is growing at a significant rate, which means less water is available per person, and some countries have not invested enough in water infrastructure. The writer maintains that for the region to have enough water to meet growing demand, it will have to focus on infrastructure development, equitable sharing, and new technologies, such as desalination. The writer concludes that while enormous challenges remain, nations that have launched bold water initiatives, such as the UAE with its aggressive deployment of desalination technology, have shown that successful outcomes can be achieved.
Outline:
Population, Access and Demand
Water Sharing Could Spark Conflict
Desalination Holds Hope
Conclusion
From the Paper
" Desalination may play a critical role in helping the Middle East contend with its growing water shortages. While fresh water may be in low supply in the Middle East, there is a great deal of oceanic salt water. Desalination uses a thorough filtration process called reverse osmosis to remove the salt from brackish water and turn it into potable water. Certain Middle East countries have been particularly aggressive about investing in desalination. As the chart below demonstrates, 70 percent of the water supply for the United Arab Emirates now comes from desalination. "

Water Geography, 2008.
Discusses terms related to water geography, safe water and dams.
2,150 words (approx. 8.6 pages), 4 sources, APA, $ 67.95
»
Click here to show/hide summary
Abstract
This paper commences by defining eight terms related to water geography such as a water surplus is a period in time when there is enough water for plants to feed and aquatic life to thrive. The author then examines that Safe Drinking Water Act (SDWA), a federal law first enacted in 1974 and revised in 1996, which promotes better standards for public drinking water under the responsibility of the Environmental Protection Agency (EPA). The third part of this paper considers the utility of dams by exploring the five primary advantages and disadvantages of dams. The author concludes that dams, as man-made structures, are neither good nor bad but rather neutral in value.
Table of Contents:
Eight Terms
Water Surplus/Deficit
Cloud Seeding
Giardiasis/Cryptosporidium
Doctrine of Prior Appropriations
Scour and Fill/Levees
Dissolved Load/Suspended Load/Bed Load
Chlorination/Trihalomethanes (THMs)
Anadromous Fish/Catadromous Fish
The Safe Drinking Water Act
Dams
Advantages
Disadvantages
Conclusions
From the Paper
"The collapse of a dam, while not often probable, is a real threat. Because of this dams require constant monitoring which can take a further toll on economic resources. Damns also redirect water, which may enable certain populations to benefit, including residents living near the dam, but may also harm the natural landscape and plant or marine life residing in the region a dam is created. While a dam may prevent flooding most of the time, it may result in the mass destruction of an entire residential area should the dam expire."

From the Paper
"Water is invaluable to the global world and to the lives of millions of people who struggle to obtain water. Water is important to economic activities including irrigated agriculture, transportation, hydroelectric energy, and other types of industries (Ghadar, 7). Many people do not realize that over 97% of earth's water can not be used for agriculture, drinking, or other uses (Ghadar, 7). Basically, many people never stop to think about the importance of water because they live in developed countries that have access to plenty of water. What these people fail to realize is that water will become scarce in these countries if water continues to be consumer faster than it is replenished."

South African Water Wars, 2004.
An examination of the struggle of 'water wars' and privatization of water in South Africa.
2,485 words (approx. 9.9 pages), 10 sources, APA, $ 75.95
»
Click here to show/hide summary
Abstract
Historically, the availability of water in South Africa has always been a problem, and this problem is mainly attributed to its geographical and climatic conditions. This paper explains that, out of the 40 million people of South Africa, 40% are deprived of the appropriate supplies of drinking water. Both urban and rural settlements are dependent on the scarce distribution of water resources by the state. It discusses how the state, on the other hand, has granted the distribution of the water supplies to a foreign company and has led to an increasing, ultimate deprivation of the water supplies for the poor, who had to choose between bread and water. It explains how this selection led to the outburst of cholera back in the year 2000, killing 300 people and infecting more than a quarter of million people.
From the Paper
"In the year 2000, Suez Lyonnaise Des Eaux, a French company, took over the majority of the water supplies in South Africa, and with this French company many other multinationals have also flown in to reap the profits like Vivendi, Saur and Biwater. It is a norm with privatization that state subsidies are reduced and the prices of the utilities goes up. The majority to suffer from the privatization reform is the general public and the poor. This is because the private companies operate under the motive of profit generation rather than the welfare of the public. This profit motive has resulted, in this case, in a four hundred percent increase in the prices of water in South Africa. Where the people who could not afford to ?buy? the water were dumped in to intense levels of poverty and the ones who could afford had to tolerate a more expensive standard of living. Poor, for whom it was even hard to live under a tin roof, were the majority of the sufferers. There were many incidents of aggression against the privatization policy and many incidents of breaking the water pipe lines for search of water. However, such aggression was conveniently dealt with force (Gleick et al., 2002)."

The Right to Adequate Water in Mexico, 2004.
This paper discusses the problem of water consumption in Mexico and the human right to water.
2,905 words (approx. 11.6 pages), 14 sources, MLA, $ 86.95
»
Click here to show/hide summary
Abstract
This paper explains, while the world consensus seems to be that the access to clean water is a basic human right, Mexico is facing one of the worst water situations in the industrialized world. The author points out that, because corporations are largely responsible for the problems now evident regarding water, they should also contribute to the provision of drinking water for the general population. The paper contends that government needs to refuse the attempt at privatization of water supplies; anytime this occurs, there is the risk of rising prices and monopolies occurring.
From the Paper
"Before one can begin to address the problem of water in Mexico one must have an understanding of the importance of human rights and what that means. Human rights are a basic core of existence for humans. It is the element that separates the humans from the animals. Human rights are things that are given to each human being so that they may exist and survive in basic need. Human rights are core needs and the meeting of them is something that each human being as the right to expect. Human rights include things like not being tortured, being able to eat, being treated without cruelty and the right to food and water at all times."

Portland?s Open Drinking Water Reservoir, 2002.
This paper is written as a report about the conditions of the water in Portland?s open drinking water reservoir.
1,435 words (approx. 5.7 pages), 11 sources, MLA, $ 47.95
»
Click here to show/hide summary
Abstract
The paper investigates many factors relating to open drinking water reservoirs such as water purification, toxic chemicals and testing systems. The paper shows the risks faced by Portland's reservoir which include the dumping of prescription drugs, waste from tankers and busses and the threat of radon in the drinking water. The paper suggests ways in which the Portland municipality could improve the situation through testing and legislation. It also includes maps of the area to illustrate points.
From the Paper
"While the water is safe perhaps it is not sterilized, which means that it does contain chemicals and other killer organisms. The best way to handle this situation is by protecting and regularly monitoring water from the main source so as to eliminate the possibility of potential contamination later on. To purify the water, treatment practices are used to get rid of the pathogenic organisms that are liable to enter into the water in the reservoir. Most of the water treatment techniques and technologies were actually developed several years ago to cure chloera and typhoid. These techniques are still applicable because they can still protect the public today like they have been for nearly a century. However, the new contaminants require new techniques to treat them, such as pathogens."

The Privatization of Water Resources in Bolivia, 2005.
Discusses the privatization of state-owned water companies in Bolivia as the government's solution to the extreme lack of access to water.
4,256 words (approx. 17.0 pages), 14 sources, MLA, $ 113.95

Abstract
Bolivia as a nation, and more specifically, the Cochabamba Valley as a region, have had significant problems recently with the lack of access to safe water resources, exacerbated by the pervasiveness of abject poverty of both the country and the region. This paper shows that the privatization of water services has been implemented as a solution to this lack of access, but so far, these reforms have been anything but successful, especially according to the majority of Bolivians. The paper shows that the results of privatization have included extreme increases in water prices, little improvement in expansion of access and extensive political protest, some of which became violent. However, the paper explains that the alternative of re-nationalization, or returning ownership and control of water resources to the state, has both potential benefits and drawbacks of its own.
From the Paper
"The policy of the privatization of Bolivia's water resources was implemented for many economic reasons, and was intended to improve upon the water industries already in place and under the ownership and control of the government. This issue has been characteristically unique from other types of privatization policies for one reason: the necessity of water for human beings to exist. Because of this universal human need for clean, drinkable water, many Bolivians claim that access to it is a right, rather than a privilege. Yet in the midst of a complete lack of alternative sources to safe water, some people will turn to possibly unsafe sources such as rainwater, lakes, and rivers. In the past, this has caused outbreaks of serious diseases such as cholera. In Bolivia, where the problem of poverty is extremely dire and millions of people cannot afford or obtain clean, safe water, the privatization of state-owned water companies has been the government's policy solution to the extreme lack of access to water."

Abstract
This paper discusses the constant population growth in Los Angeles County and the ensuing problem of water shortage. The paper presents the statistics of water consumption and explains that county officials are obligated to implement water conservation measures to curb problems of shortage. The paper examines several methods of water conservation and explores the option of a desalination plant.
From the Paper
"The population of Los Angeles County has done nothing but grow. As of 2004, it had reached approximately 10,103,000 (Overview, 2005), with only the promise of continued growth for the foreseeable future. For the period 2004 to 2014, the population of Los Angeles County is expected to increase by an average annual compound rate of 0.61%, according to a report from Integra Realty Resources of Los Angeles (Integra, 2005). According to the Los Angeles County Department of Public Works, the average Southern California household uses 500 gallons of water each day (Los Angeles, 2005). Assuming four people per household, that amounts to 1,262,875,000 gallons of water per day, or 460,949,375,000 gallons of water per year just for Los Angeles County. For the entire region of Southern California, the figure can only be higher."
