Water Supply And Sanitation Within South Africa
Although there are a wide variety of contributing factors and issues related to water supply and
sanitation within South Africa, some are more prominent than others. One of these is the
continuously increasing amounts of people moving into the city from smaller areas and villages;
these larger, more dense populations of people have also increased the water demand. To keep up
and hopefully adapt to these largely increasing needs for clean and readily available water in the
cities, many plans to prevent a more widespread lack of water supply and sanitation in these areas
have been made. The issue is, however, that most of these plans have either not been funded, put
into action, or completed. In addition to this, the structures that are currently in place are in poor
condition or near collapsing. Some of these failed proposals include the construction of dams, to
help maintain the water supply, and more advanced filtration systems to ensure that the water is safe
for human use and consumption. Lack of proper implementation and maintenance of plans to help
with water supply and sanitation in more populated areas is, needless to say, a majorly contributing
factor in the history of South Africa's water crisis (Water).
As water supply and sanitation is either non–existent or ineffective in cities and more largely
populated areas, it is also struggling in rural areas such as smaller villages. Part of the reason why
access to clean, usable water is unavailable is because of

Decline in Water Supply in India
Introduction
The available water in India has declined drastically over the past several decades due to the rise in
demand for water sources across almost every industry. This shortage has greatly affected all
activity in India, including the agricultural industry and the available drinking water for domestic
life. The Food and Agriculture Organization of the United Nations, or the FOA, believes that India
will literally run out of water if certain steps are not taken to replenish India's aquifers. To fully
grasp the matter, an explanation of the problem is below.
The main cause for concern is that India's flourishing agricultural industry uses the 91% of water
throughout the country leaving aquifers at lower levels every year. ... Show more content on

Fluorosis Epidemic in India – Fluoride is a geologic material that lies underneath most of India. As
water tables decrease, farmers are forced to drill deeper into aquifers to unsafe zones containing
dangerous levels of fluoride. In India, the Fluorosis and Rural Development Foundation have
estimated that over 60 million people suffer from diseases caused by the overexposure of fluoride in
drinking water from underground aquifers.

A Brief Note On Water Supply And Sanitation
Water supply and sanitation is a problem in developing nations as they lack the proper resources to
install a water collection foundation. Bolivia can be considered a developing nation that has a water
supply problem as they do not necessarily have the proper infrastructure to supply their population
and they also lack a water regulation program. The village of Lupalaya is a small settlement located
at approximately –16.195 degrees latitude, –68.841 degrees longitude with an estimated elevation of
12,600 ft above sea level on the shore of Lake Titicaca. The village is also located 60 miles NW of
the largest populous city in Bolivia of La Paz. Due to Lupalaya's proximity to La Paz the village is
greatly affected by the La Paz–El Alto concession which led to the privatization of water supply and
sanitation.
Introduction
Bolivia is a landlocked country located in central South America. The village of Lupalaya is located
five miles from the west–central border with Peru on shore of Lake Titicaca. The village is also
located in a small mountain valley no more than .35 miles across. Lupalaya is also found on the
Altiplano at the high elevation of 12,600 ft above sea level. Even though Lupalaya is a small village
they are surrounded by many other villages and cities including the most populous city in Bolivia,
La Paz. Bolivia has a wet and a dry season throughout the year and this can turn into a problem
when the need for water is great but the groundwater levels are low,

Qatar is the largest global supplier of helium. On June 5, 2017, Qatar made an unexpected move to
cut down the global supply by 30 percent. Further, the government has threatened to inflate the cost
of instruments used for scientific and engineering purposes as reported in the "Chemical and
Engineering News" (Reisch p. 1). This news relates to suppliers since it focuses on supply
constraints for a scarce engineering resource. The global demand for helium has been growing over
time, and the gas is widely used in different fields, such as in the manufacture of electronic
equipment, in medical imaging, in magnetic resonance, in chromatography (as a carrier gas), and in
mass spectrometry (Reisch p.1). Current State of Affairs: The cost of helium in the United States
quadrupled between 2011 and 2013 due to supply limitations. As a result, the globe suffered from a
severe shutdown of scientific instruments (Reisch p.1).The current situation could be temporary for
some helium consumers with advanced recycling equipment. The move by Qatar was political.
Recently, the country was accused of supporting and funding Islamic religious extremists. In fact,

The Effects Of Water Quality On The Water Supply Of...
Body Paragraph #1 – Background:
Water is perhaps the most important component of any ecosystem. All living organisms need water
to grow and survive. As human population continues to grow, we need to understand and determine
the effects our habits will have on the ecosystems and our water supply. Four factors that can affect
the quality and importance of water are its abilities as a solvent, dipolar, benefits and costs.
Acceptance and long–term sustainability of water quality interventions are pivotal to realizing
continued health benefits. According to the EPA (2015), "only 3% of the world's water is suitable for
drinking, 2% of which is found in glaciers and ice, so in reality, only 1% of the earth's water is
accessible and potable".
Body Paragraph # 2 – Objective:
This paper highlights the need to effectively involve and design interventions to determine human
factors that can cause damage to the supply of drinking water and the damage to the environment.
Furthermore, that interventions are required to improve water quality and supply. A number of
settings and experiments were conducted of initial water sources and the effects that household
factors can lead to determine water qualities and levels of contamination. The results would show
how such household chemicals like oil, vinegar and soap cause turbidity, odor and color change in
water supply.
Body Paragraph # 3 – Hypotheses:
The premise for each experiment would have different results for a conclusion

How The West Overcounts Its Water Supplies
Abraham Lustgarten has written a very informative article that is published by Pro Publica and titled
"How the West Overcounts Its Water Supplies." In great detail, he analyzes the drought situation in
Arizona and California to draw attention the underlying cause: the miscounting of available water.
There is miscounting because officials are refusing to legally accept that the major water resource of
the West–the Colorado River–is interconnected with underground water resources. All in all,

Matuska who is directly involved with the water accounting as a source. Another person he
mentions is John Bredehoeft, a leading hydrologist and former director of federal governments
Water Program, who clearly states the importance of accurate water counting. All these individuals
help a reader to trust the information that the author gives. Looking further into the author's use of
appeals, Lustgarten also uses Pathos (emotional appeal) and Logos (rationality), which help prove
his point. Lustgarten ends the article on a very skeptical note and an unpromising remark on the
future, which makes the reader feel the urge to take action upon the issue. He says, "Until state
officials do [realize the interconnection of ground and surface water legally], it seems unlikely that
there will be any real solution to managing the Southwest's strained water resources for the future."
Along with Pathos, Logos is also very well used. There are a lot of direct quotes from well–
informed experts that bluntly support his stance. These informed opinions from experts, help the
reader rationalize how valid Lustgarten's points are. Also adding to Logos is his overuse of multiple
facts to prove a single point. Further appealing to the audience's rationality, he explains why
officials aren't putting in the change to help solve the water accounting issue. He then very logically
proves where the fault in the official's mindset is. He states that officials don't want to inflict change
because

Pulaski County Water Supply
I conducted a survey of Pulaski county residents to get their opinion about the Pulaski county water
supply. The purpose of the survey is to get others viewpoint of Pulaski County drinking water so
that we can improve our waters system. In the Article "Arkansas Rivers is Too Polluted to Touch"
written on April 24, 2000, it states "The river is fairly clean as it flows into Wichita, but by the time
it leaves the city, the water is so dirty it is not safe for wading, fishing and touching, said Tom Stiles,
chief of the office of planning and prevention at the Kansas Department of Health and Environment.
The river also is not safe for canoeing, kayaking or water skiing." Have Arkansas Rivers improved
within 14 years? This question will help us to see how far Arkansas Rivers have come since the year
2000. According to Carl Safina in "Song for the Blue Ocean" he discussed how pollution can
interfere with not only wildlife and aquatic animals, but humans as well. Pollution can get into our
water system causing bacteria and diseases. These waters are the same that runs in our faucets and
pipelines. I will discuss resent studies of central Arkansas water quality later in the survey report.

to do some research on our water supply. In this country, we have 4.5 percent of the world's

system in the world, the Great Lakes, which holds 6 quadrillion gallons of water(Grace,2017). These

Glenton adds that "In 2000, Americans used a staggering 408 billion gallons of water each day."
Utilizing the given statistics, it's safe to assume that the number of gallons being used by american
daily have increased tremendously. Yet, these numbers are dramatically different if compared with
less–developed countries. In an article written by Mark Fischetti, an author for The Scientific
American, Fischetti demonstrates that "The U.S had the highest per capita water footprint, at 2,842
cubic meters per year." However, India's footprint is "only 1,089 cubic meters a year." Comparing
the population of the U.S (322 million) to the population of India (1.252 billion), it's clear that a
more developed nation takes advantage of it's water resources. As a result of more privileged nations
taking their water resources for granted, it has become apparent that less privileged nations
experience the most backlash. As a result, the fresh water scarcity has caused the rapidly increasing

As the water supply decreases, humans and animals don't have as much to drink, and it kills many
plants that are evolved to living in and around the water. When the water is poisoned, it kills many
species that live there by making the water undrinkable. Then it gets into our water supply, as
mentioned in source 1, (Past and Present: The Florida Everglades), paragraph 1, "The Everglades
have always existed in a delicate balance – even the smallest change can have a large impact." This
basically proves that if you throw one small factor into the delicate ecosystem, (such as harmful
chemicals or a lack of water), it can have big changes and cause many problems, (such as killing
thousands of species and shrinking a beautiful national park). The beauty that was once expressed in
this diverse terrain is now crippled due to human activity, and despite acts to preserve it, the Florida

Water is the most important substances on Earth as it is essential for the survival of all species.
Water covers seventy–six percent of our planet, and it is easy to think that it will always be plentiful
(Girard). However, the way society misuse the substance makes freshwater start to become
incredibly rare. The global water supply is becoming more of an issue every day. Water is a resource
that much of the developed world takes for granted, but that many in the developing world struggles
to find enough of everyday and even in developed nations, where a plentiful supply of water is
sometimes taken for granted. The struggle for fresh water could spread as climate change and other
manmade pressures change the availability of water around the globe, and as Earth 's population
grows ever larger. If we continue to misuse the Earth's water supply, society will be at war over
water because of the high rise in pollution, climate change, and the privatization surrounding the

Unique to Melbourne's Water supply is it protected catchment areas, and is the key reason for very
little treatment required (Melbourne Water 2014). Majority of the water feeding into the dams comes
from the Yarra catchment regions, starting in the Great Dividing Ranges; figure 1.1 shows the
regions for the catchments. The vast majority of the area is in protected National Parks.

Protected Catchment
The protection of the catchment allow for a natural filtration system to occur before water enters
reservoirs. This is important as "deeps soils acts like a sponges to hold rain water, the filter and
slowly release into springs, stream, creek and river" (Melbourne Water 2014) that feed into to our
dams. This is the factor that decreases that amount of treatment required for a clean drinkable water
supply.
Melbourne has 90,800 hectares National Park (protected) – majority of area is inaccessible for
public, limited to low impact activities such as bush walking
Water Catchments – Open Catchments
While most of Melbourne's catchments allow limited public access, a smaller proportion of our
water comes from open catchments. These areas contain farmland, rural properties and state forests
that are open to activities such as camping and four–wheel driving and small amounts of timber
harvesting.
The water from open catchments is put through a filtration treatment process, so it meets the same
drinking water quality requirements as water from protected catchments.
An open catchment is considered to be from area with no/ minimal protection. This mean that the
water from these areas can be highly polluted and require extensive treatment. Farming land,
recreational areas, run off from roads are all considered to be open catchment areas.

Benefits Of Water Supply On Earth
Limited amount of water supply on Earth will lead to negative effects. The depletion of our water
resource is more serious than that of our current oil depletion. There are substitutes for oil but
nothing can replace our drinking water. We are in a generation where people believe that water is a
reusable resource that we will never run out of. But in the future, it is bound to not be able to keep
up with us. Global conflict will happen over this natural resource if nothing is done. Food
production will not be able to keep up with the speeding population increase, and our overall
economy will suffer. Due to the limited amount of fresh water in this world, and the demand going
up due to populations, many people of the world are suffering or will be suffering. Before I talk
about the issues of having a lack of fresh water I must talk about how water is becoming scarce and
if we don't start preserving it, we may have a serious epidemic in our future. Also, people in certain
locations end up in poverty because of the lack of fresh water in their area. Water is a human right
and every person deserves access to it. The location of where you are living plays a big role in if you
are being effective by the water crisis. Many people in other countries are struggling due to limited

The Challenge Of Sustainable Water Supply
1.0 Introduction The challenge of sustainable water supply and management in arid areas is
magnified by the climatic condition of these regions. The areas often experience a period of six
rainless months every year. The areas also experience low and unpredictable annual precipitation of
around 100 to 500mm per year as well as extreme potential evaporation (Bunn et al. 2006, p.174).
The impact of climate change primarily affects the amount of fresh water supply in arid regions.
There is a substantial decrease in the amount of fresh water in the regions due to these climatic
variations. The plan outlines two techniques of creating a diversified, and adaptive freshwater
supply system in the arid regions worldwide. 2.0 Background Water is an ... Show more content on

Arid areas need a concerted effort of every individual to contain this situation. This report offers two
techniques that can be effectively used to ensure availability of fresh water in arid regions. These
techniques include artificial ground water recharge and desalination technology. The two methods
will be characterized by increased storage capacity to supplement the unreliable rainfall and lack of
new fresh water supply in these areas during dry spells (Kingsford, Biggs & Pollard 2011p.1196).
Finally, the techniques will improve the production and supply systems for desalinated fresh water.
The graph represents fresh water supply in arid areas. With the change in climate conditions, the
water supply level falls from 6.3mm/household to 5.4mm. The supply decreases further as shown by
series 3 to a bear 2.0mm. This drastic fall must be deterred using the techniques that would be
proposed in this report. 3.0 Presentation of the two techniques 3.1Desalination technology
Desalination is the process through which pure water is recovered from saline water using various
forms of technology. The two major commercial desalination technologies include thermal
desalination and membrane processes. Osman (2005, p.209) asserts that the technology is critical to
water management, and it works independently of climatic factors. Thus, the method can be used to
supply fresh water consistently regardless of the weather in the arid regions. However, the

Water Supply As A Critical Infrastructure
One of the basic elements required to sustain life is water. Water is of extreme importance as the
body cannot go without water for more than a few days. Therefore, the supply of water is a
paramount concern amongst society. The availability of water is not the only concern. Another
factor is the purity of the water supply. Imagine the catastrophic sequence of events if the water
supply for a region were to be contaminated with Ebola or any plethora of deadly viruses. Following
such a tragedy to conclusion would leave thousands or possibly millions dead depending upon the
detection and response procedures. It is no surprise that water supply is considered a critical
infrastructure. This paper will discuss these topics in depth to cover what measures are currently in
place to detect water anomalies and response methods to any such contamination, accidental or
intentional. Furthermore, we will look at how water is scrutinized in many different areas from
chlorine levels to salt levels. The level of scrutiny in water will likely shock anyone, yet fear will set
in at the reality of how vulnerable this water supply system is to attack.
In society we take many things for granted, especially those that would be deemed a basic necessity
such as water. Nevertheless, we give no thought to the consequence of disruption in availability until
it happens. Natural catastrophes have recently reminded us of how vital these necessities are that we
take for granted.

However, summary and Statistical Report of the 2007 Population and Housing Census of Ethiopia
does not show the inter–censual growth rate by place of residence. The inter–censual growth rate by
place of residence would have shown urbanization and urban population increase in the three census
years (1984, 1994, and 2007).
According to WSDP (2002) in 2001 urban water coverage of Ethiopia is 74.4%, and population
served reaches 9,886,000.The water coverage ranges from 25% in Harar to 96% in Amhara region.
However there are discrepancies among different documents regarding urban water coverage. For
instance WSDP (2002) in Assefa (2006) indicated the urban water coverage of

Water Scarcity Of The Colorado River Water Supply
As humans, we have a few basic needs. Some of these being security, shelter, food, clothing, and
arguably most important, water. When living in a desert though, water may not be quite so readily
accessible. With recent droughts in the southwest and the already relatively scarce amount of water
and rainfall in Arizona, now is the time when Arizona should begin to make itself more efficient and
conservative with its water consumption, because of our reliance on the Colorado River and rapidly
depleting groundwater sources and the rapidly growing population and its water demands.
Arizona has an incredibly large dependence on the Colorado River and groundwater. In fact, 39% of
all water usage in Arizona is comprised of Colorado River water. Any dependence of that scale on
any resource that originates in another area is always a major risk, as any major disaster or drastic
change to the source of the river can cripple the state's water supply. Furthermore, while Arizona
does house the majority of the Lower Basin of the Colorado, the Colorado's Upper Basin is shared
between 4 other states, all with their own water needs and all with a susceptibility to drought. On the
other hand, another 40% of all water Arizona uses is from groundwater sources. However, the
Colorado River and these groundwater sources in the Colorado River basins have lost over 65 cubic
kilometers of water over the last 9 years, with nearly 2/3 of it from groundwater loss due to over–
pumping. This is because

Urban Water Supply and Demand
1 – INTRODUCTION Water availability critically influences human well–being and directly affects
ecosystems and the environment. Water supply and demand issues are especially more complicated
in areas of rapid urban and population growth. Projections say that 46 to 52 countries and a total
population of 3 billion people will be water stressed by 2025 (Rosegrant, 1997). And to increase a
little bit more the complexity, there is the fact that water availability is not homogeneous. Water is
irregularly distributed and, consequently, water problems are region–specific. Water supply and
demand problems usually fall into the wicked problem category. Their complexity is based on the
fact that they have many interdependencies, are ... Show more content on Helpwriting.net ...
Groundwater supplies and surface water supplies outside of the local catchment area are commonly
used when the local surface water supply is insufficient. Increasing levels of groundwater
exploitation can significantly decrease groundwater levels, leading to several environmental
problems. An example is what's been occurring in the North China Plain, where the mean depth to
water changed from 7.23 m in 1983 to 11.52 m in 1993, characterizing a decrease of approximately
0.5 m per year (Changming et al, 2001). Groundwater table drops at those rates can severely impact
the environment. Groundwater depletion can lead to the formation of depression cones, which can
often cause land subsidence. Water level drops in coastal areas result in intrusion of seawater,
deteriorating the water quality. And, in urban centres and surroundings, water resources are
threatened by untreated urban and industrial wastewater discharge. The increasing demand for water
resources can severely affect natural ecosystems. For the construction of a dam, a large area is going
to end up under water, severely impacting terrestrial ecosystems. Overexploitation of water for
irrigation can seriously affect aquatic ecosystems. An example of that is what happened in the
Klamath River (Oregon, USA): more than 30,000 salmon perished because farmers were allowed to
withdraw unsustainable

Water Supply And Its Effects On Earth
At this point in time, most of the inhabitants of this planet have learned to survive. One way or
another, every living creature on earth has used one of its resources to live. One of the greatest and
most important resources the earth has is its water supply. Plants, wild animals, and specifically
human beings use what the earth has given us every day. This being a fact of life, we as humans
have constantly examined the state of the earths resources to make sure we have enough. Sadly, the
facts are true. One of the most valuable resources on our planet is quickly being depleted. It is
arguably the most necessary factor to sustain life on earth, and we as humans use it more than we
know. Water used to cover up at least 75% of the earths surface, though scientists believe that
number is rapidly decreasing as time goes on. As the human population increases, the need for water
also increases, making it difficult for the rest of planet to flourish. One might think, "Why should I
worry about the water supply? There will be enough for me to live till I die, so who cares?" This
foolishness is very common among many, not only around the world, but especially in the United
States of America. As Americans, we feel a constant entitlement to all that might be out there in our
vast land. This means opportunities for a better life, but it also sets precedent for taking our
resources for granted. Yes we might have plenty of water for our lifetime, but what about the next
generation? What

Contamination Of The Water Supply Of Flint Essay
Contamination of Water Supply of Flint, Michigan
Name:
Institution:
Contamination of the Water Supply of Flint 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 lead effects in the drinking water have caused a massive public health crisis ("Scientific
Opinion on the risks", 2015). The whole crisis was as a result of poor management practices
employed in the Flint water plant. The city decided to switch the

The Scarcity Of Water Supply Crisis
Over the past decade, many brows have begun to raise about the current issue regarding water
supply. The water supply crisis is a major world problem, and many countries around the world have
started to feel the effects of water scarcity. There is a picture in the Few Resources article that shows
the predictions of the world's water scarcity in the year 2025 if the rate of water extraction remains
the same as it is now. In the picture, almost every country will be facing some sort of water crisis,
whether it be an economic shortage, or a physical shortage of water. As stated in the Few Resources
article, "By 2025, 1.8 Billion people will be living in countries or regions with absolute water
scarcity, and two–thirds of the world population could be under stress conditions." (Powers) This
statistic is very startling, as the majority of the world's population will be effected by this problem
regarding water supply. Many people wonder, how did this crisis come to be and what can be done
in order to prevent any future problems? Both of those questions will be discussed within this essay,
starting first with the history of this water crisis and how it came to be as big of a problem that it is
today. Water is the building block for everything else in the world today. Without water, almost
nothing is possible. Arguably the most important aspect of water is that it enables humans and all
other walks of life to survive. But with this comes the ever–growing problem, how will the

The Current State Of Water Supply
Introduction
Water, although considered a renewable resource is not available for infinite use as only six percent
of the world's total supply is fresh water. Only this fresh water can be directly used for daily human
needs and thus the amount of water actually available for use is much lower than the total amount of
water present on the earth. The limited amount of water then poses the issue of water scarcity in
some areas and makes the wise use and sustainable management of water extremely important. To
ensure this sustainable management of water and prevent any misuse, it is important to have an
appropriate institutional framework that looks after the water supply. The lack of a proper
framework in the past has lead to the shifting of water management from the hands of the
government to the private sector (Prasad, 2007).
The purpose of writing this essay is to look into the current state of water supply, the issues
surrounding the water supply and the correct method to overcome the prevailing issues. This essay
will answer the question is privatization of water the solution to solving the current water crisis in
different parts of the world? I will argue for the need of a public–private partnership to ensure a
balance between the private sector and the government. In Section (1) of the essay I will talk about
the failings in the current water system and the reasons leading to a shift towards privatization.
Followed by Section (2), which will simultaneously address the

Flint Water Supply Case Study
Flint, Michigan is a city in a dire financial situation. In 2011, the state of Michigan assumed
complete budgetary and financial control of the city and began implementing several cost–cutting
measures in an attempt to alleviate the situation. Of these cost–cutting measures, one of them was
changing the source of the municipal water supply source. Flint's water supply was sourced directly
from the city of Detroit, whose reservoir came from one of the Great Lakes, Lake Huron. In an
effort to save money over an extended period of time, the state devised a plan to construct a new
water supply line which would directly provide water from Lake Huron to Flint, Michigan.
However, given that the construction of a direct pipeline would take several years to execute, the
state of Michigan devised an alternative short–term plan to acquire water from the nearby Flint
River. ... Show more content on Helpwriting.net ...
Nonetheless, there was a major flaw with their short–term plan. Michigan's Department of
Environmental Quality failed to take into account the treatment of river water for human
consumption. Initial planning and gathered evidence suggested the purification of the river water for
human consumption. This was clearly a requirement. Furthermore, more important was the
mandatory introduction of an anti–corrosive agent in the water supply. Since the Department of
Environmental Quality failed to implement both of these essential requirements, the water from the
Flint River began corroding the water supply pipes that led directly to homes. Several of the pipes
were antiquated and composed of lead. This caused an excess in lead in the water supply, way above
the maximum imposed by federal guidelines. The combination of all these problems generated
severe health problems within the community of Flint,

Public Water Supply For Drinking And Agricultural Water
Brazos River, the streams and lakes along the river are a major source of public water supply for
drinking and agricultural uses for communities in around the Brazos River basin. Segment 1242 of
Brazos River and the watersheds (Leon River watershed and Lower Brazos–Little Brazos
watershed) and their tributaries flowing into Brazos river in this segment are known to be impaired
for bacteria, salts, nutrients and chlorophyll–a (TCEQ, 2013). The flow of nutrients from rain water
run–off from land into Brazos River results in eutrophication of the river and algae (Chlorophyll–a)
bloom, thereby reducing the dissolved oxygen content in the water. This hypoxia in the water causes
the death of fish and other living organisms in the river. This can ... Show more content on

4.2 Objectives
The purpose of modeling the fate and transport of pollutants in surface water is for a better
understanding of the relationship between pollutant loads during rainfall events and to be able to
simulate and make predictions of future water quality conditions. By connecting stream flow rates
model to pollutant loads, the relationship between pollutant transport and water quality can be
determined. For this research, models of the fate and transport of the chloride and sulfate in Leon
River was constructed.
4.3 Conceptual Model
The conceptual model for this research is a network model which models the rate of flow of
pollutant through a connected network of points in surface water. The water quality monitoring
stations represent such points and serve as containers. From analysis of the water quality monitoring
measurements of pollutants at each chosen station, it is observed that the concentration levels of
pollutants tend to be high where it has not rained for a long time compared to where it rained the
previous day or few days ago. This then can be interpreted to mean that the concentration of
pollutant in surface water is proportional to the amount of water in the surface water body. Drought
condition will concentrate the pollutants, while on the other hand rain events help to dilute the
pollutes because of increase of water and also contribute to the flow of the pollutant from one point
to the other

Water Supplies In Ancient Civilizations
Earliest civilizations developed in major river valleys, yet they developed different strategies to
manage water supplies. The way that societies addressed these central concerns was oftentimes
dependent on the nature of the rivers that they tried to manage" (Backer, 2016). Civilizations were
dependent upon water for its bountiful resources and advantages. Water fueled and made possible
adequate agriculture and as well, provided a natural resource for clean drinking water and bathing as
well as a resource for building materials.
"Persian laborers built aqueducts and cisterns to store water, and the government built thousands of
miles of canals known as qanat to move water some distance– usually many miles–from an original
source, such as

Essay On Water Supply System
In a recent proposal the state of California has decided we need to take further action into protecting
our water reliability. Officials are suggesting that we should spend $20–50 billion into creating a
two new tunnels known as the California WaterFix system from the Sacramento River to the Delta
pumping plants in the Southern Delta, with funding being allocated from both agricultural and urban
users. Although there are some benefits from creating a new water project, it would have far more
negative externalities when it comes to economical, environmental, and corrupt agribusinesses. To
invest in a completely new water supply system is economically unreasonable. The total costs to
build the tunnels could go over $20–50 billion, ... Show more content on Helpwriting.net ...
The California Waterfix proponents often mention that building the new tunnels will be safer and
more reliable towards the fisheries and the ocean outflows. However, the co–plan Bay Delta
Conservation Plan is deceitful in its true intentions. By shifting the Sacramento River with the flow
of fresh water, it would lead to an even greater rise in sea levels along with climate change. By
focusing our investments into restructuring the current Delta levees with an increase in outflows and
state of the art fish screens, it would preserve the endangered marine life. Also, there is an ongoing
fear within Southern California residents with the topic of earthquakes, finding comfort with the
"reliability" of the new Waterfix systems. In the case of the surrounding areas of the Delta, it's
almost impossible for the system to be completely protected against water breaks. Investing in new
tunnels won't change anything in how our system will put up against a natural disaster. The main
audience that benefits from building the new Waterfix system are the agribusinesses and oil
companies. In particular, the Kern County Water Agency, Metropolitan Water District, and the
Westlands Water District are big proponents in building the tunnels for their own personal gain, even
though they already receive plenty of water from the Bay Delta. Instead of paying directly for the
regulation of the WaterFix tunnels, taxpayer money would subsidize water for private

Water Supply In California
The second largest consumer of California water is public supply. Public supply has to do with both
public and private water suppliers, which provide water to others. Public supply water usages would
have to deal with domestic, commercial, industrial purposes, and public serves such as pool, parks,
firefighting, etc. Public water supply plays a huge role in many counties, and communities. The
reason why is because the public water supply systems that are located in these
counties/communities are government or facilities that are privately run. These public water supply
systems are what provides people with water to use on an everyday basis. The water that is
contribute to humans from the public water supply is taken from rivers, lakes, reservoirs, and ...

But humans are not the only species that need water. Animals and plants need water as well and
without it there would be nothing to live off and everything and everyone will just fade away. In
California, water is used mostly every day and it has to start when someone starts there day.
According to Environmental Protection Agency (EPA), stated that "the average American family
uses more than 300 gallons of water per day". This means that an average household would contain
at least three people, that max would be four. If one average family uses up to 300 gallons a day.
Then who can imagine how many other average families use 300 or more gallons of water per day.
But this only includes the amount of water that is used inside the house and does not include the
amount of water used outdoors. Outdoors water usage is only 30 % of the household use while the
other 70 % is indoors. Outdoor water usage may include watering lawns, flowers, washing cars,
kidding pools or slid n slides for when the weather is

Global Sustainability and the Water Supply
The increase of global urban population has become a critical issue that the world is facing; as the
world population continuously increases, the need for natural resources (Land, water, energy and
food) also increases. However, natural resources are known to be finite. Which is why sustainability
has become a major concept during recent times. Based on the US Environmental Protection
Agency (ND), Sustainability is based on a simple principle: "Everything that we need for our
survival and well–being depends, either directly or indirectly, on our natural environment.
Sustainability creates and maintains the conditions under which humans and nature can exist in
productive harmony, that permit fulfilling the social, economic and other requirements of present
and future generations." Bloomberg, an international news agency in the US, reported that it was
recently found by an Ernst & Young study that 76% of corporate representatives think water, which
is what this essay will discuss, is the top resource at risk. (Bloomberg: 2013) Water makes up around
70% of the world's surface. Less than 1% is freshwater, and only 0.4% of it is accessible for human
use. (Global change: 2006) These statistics prove to show how water is limited within the cycle it
goes through. The global demand for water has vastly increased in the past few decades, making
demand exceed what is available for direct use. Nearly 768 Million of the human population,
roughly 1 in 10 people, does not have access

Water Supply In Canada Essay
Canada should do a Better Job Protecting Its Water Supply Since the start of time human kind and
all other living things on earth have been dependant on a clean and smooth flowing water supply.
Water is an essential part of survival on earth and that has stood true since the start of time. As
droughts around the world increase and areas turn in to "dust bowls" the demand of exportation of
water from countries like Canada grows tremendously. Due to this I whole heartedly disagree with
the topic and in fact encourage the Canadian government to send large bulks of water to areas of
need. Statistically speaking Canada's water consumption levels are very high. "Canada owns about
9% of the world's freshwater while only having 1% of the world's population. An average Canadian
uses about 1600 cubic meters of water yearly, this is double how much the French use and 8 times
the world average." We as ... Show more content on Helpwriting.net ...
Another reason I am not in favor of Canada protecting its water supply is because of the difference
between us and others around the world. Considering currency change and the amount of resources
surrounding us, we have a lot more goods including a strong water supply from the Atlantic, Arctic
and Pacific oceans, the Arctic ocean also leads in to the great lakes which is very beneficial to
Canadians from an economic standpoint. A research done proved that "20% of the world's richest
own about 86% of all goods on earth, while the 20% poorest own as little as only 1% of the world's
goods." If we were to use this information and applied that to "Canada vs The World" we would all
clearly understand that it is our duty as a nation to unite together and create equality around the
world by sharing goods such as water. The earth is something we are all part of, when something
goes wrong in one part of the world it has a ripple affect somewhere else. As citizens of a strong
state it is our duty to think about the common good of

New York City Water Supply Systems
HISTROY OF NEW YORK CITY WATER SUPPLY SYSTEMS
Historical Overview
Between the 1840s and the 1960s, New York City established the greatest metropolitan water
distribution system internationally. Even though NYC's Water system is a work in progress it can be
considered one of the best in respects to its quality, reliability and innovative management.
At the beginning of the 19th Century, most American cities were small in size and usually coastal.
Their infrastructure was primitive even by the standards of that time period. Street lighting was rare,
roads were unpaved, and water supplies were really inadequate. The water surrounding NYC was
tidal and mostly saltwater. They had no direct access to fresh water. Initially, Residents depended on
wells or rain–water cisterns for their water needs. External wastes contaminated the water aquifers.
Rain–water did not help increase the main supply. Flush toilets were introduced to the city in 1819
that increased the need for water usage. (Weidner, 1974, p. 55)
The establishment of city water supply was regarded as a private, residential matter rather than a
public function in the early 19th Century (Blake, 1956). The State depended on privately owned
companies to supply water for its residents rather than undertaking the responsibilities themselves.
The Manhattan Water Company was chartered in 1799. They had the sole rights to supply water to
the city. They had a reservoir built in the city to provide over 400 of NYC most elite

Water Supply At Risk Of Depletion
Water is a crucial component to sustain human, animal, and plant life. When a problem that puts
water supply at risk of depletion is encountered, people should concern themselves with the
inevitable detrimental effects of water shortage. California inhabitants are currently faced with this
problem. Although all of California's citizens have some awareness to California's drought issue,
many are oblivious to the drought's severity. They continue to leisurely use water due to
assumptions that the drought is short term or that the lack of water is normal because the state is a

Fortunately, there is a solution, and it can be implemented in every household in California. A
greywater system is a noteworthy solution, although extremely unknown to the general population.
Greywater is generally known as water that has already been used from different household
appliances such as the kitchen sink and laundry machine, but excludes water from the toilet. It
"constitutes 50–80% of the total household wastewater" (Li 3439). Greywater makes up the majority
of a home's wastewater. As a result, the greywater system focuses on recycling the wastewater in
order to promote water conservation. In "About Greywater Reuse," the article explains that the
system recycles greywater by trying to find a way to "pipe it directly outside and use it to water
ornamental plants or fruit trees." In addition, the system provides homeowners a convenient way to
complete the daily chore of watering their plants. The greywater system is innovative and provides
homeowners a chance to contribute to California's relief from its drought. Although unknown to
many, the greywater system proves to be the most promising solution to preserving California's
water supply with its benefits to homeowners and ability to conserve large quantities of water. There
is already a plethora of solutions to California's drought that people are more aware of than the
greywater system. One solution that has been persistently advocated is to simply reduce daily water

Once a light beam shines through the flame, the atoms absorb some of the light. It is then detected,
recorded and compared to a series of standard solutions. In the absorption spectrum, the absorbed
light show up as black gaps. These distinctive gaps indicate the difference in energy levels for a
particular element. If this can be compared to the concentration of its standard solution, then it can
form a calibration curve. c/ an assessment of the importance of the technique in developing chemical
understanding and as an application in other fields AAS has contributed to the understanding of
elements having different absorption emission spectra due to their difference in energy levels. In the
absorption spectrum, the absorbed light are shown as black gaps. As the number of electrons
increase, the number of spectral lines also increase. Hence, by measuring the absorption of light, the
concentration of the element within a sample can be determined. By knowing the concentrations of
an element, scientists are now aware that even the smallest amount can make a significant impact
towards the biological system. Therefore, scientists have brainstormed ways to monitor the use of
