Essay on Water Treatment Process
Clean water supply is essential in establishing and maintaining a healthy community. There are two
sources of water supply which are the surface water and ground water. Most natural waters are not
suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals.
In addition, as a city grew, wastes from human activities contaminate most of the water supplies.
Water treatment plays an important role to properly treat a contaminated source of water supply in
order to protect the health of consumers. Water treatment process is defined as a process of
eliminating pollutants from untreated water to produce a biologically and chemically risk–free
water, which is both potable and palatable for human consumption...show more content...
The second step of water treatment process is aeration. At the aerator, raw water is mixed with
air. The aeration process helps to provide oxygen to the raw water which is needed for the
oxidation process of dissolved iron and manganese in order for it to precipitate and therefore
enables its removal through filtration (SAJ Holdings Sdn Bhd., n.d.). Wormleaton and Tsang
(2000) stated that for water treatment process and also natural streams, it is essential to maintain a
high amount of dissolved oxygen. Aeration also provides the escape of dissolved gases, such as
carbon dioxide and hydrogen sulphide to reduce the corrosiveness of water, thus controls the tastes
and odors of the water (Shun, 2007). Groundwater with high dissolved carbon dioxide levels or
high concentrations of iron and manganese commonly require aeration as well as water drawn from
reservoirs that is low in dissolved oxygen.
Thirdly, the proceeding water treatment step involves coagulation and flocculation. The objective of
this step is to produce particles of a size that can be easily removed by settlement and filtration.
Coagulation destabilizes the colloidal particles followed by flocculation whereby larger particles
are formed from small particles through collisions. Conley and Evers (as cited in Hendricks, 2006,
p. 277) described coagulation as a process that reduces the surface charge

Argumentative Essay On Drinking Water
Water is a very important commodity to live. Some people say it's a right, but others at as if it's a
privilege, and as a result, people lack it. The human body is about sixty percent water, but in what
I have seen just in my twenty years of life, people do not drink merely enough of it. Instead, water
has been replaced as a go–to drink by things like milk, coffee, pop, or energy drinks, but natural
energy lies in water. With water we can be more energized, awake, and of course, hydrated, which
all together collaborate to help us flourish, stay healthy, and live long. It's most of the earth's
surface, too; water's all around us, but we neglect it and deny its crucial place in our health and
humanity. My parents always told me to "drink milk" at meals, so I grew up thinking water was
something one only drank at restaurants to save money. It's flavorless, not delicious, and lacks and
nutritional value. I have learned the necessity of water the difficult way. Safe to say, I did not care
about drinking water the majority of my life. I only drank approximately twenty–four ounces of
water a day, on a good day, if even that, and that's just in the past three years. The past two years I
have fainted, blacked out, and become dehydrated because I did not drink enough water, so I
learned pretty fast into college that if one is going to be running around going so many places and
doing so many things as a seminarian that energy was essential. Isn't coffee or pop a quicker method,

Descriptive Essay About Water
"Come on guys get together for a picture!" This is most likely what my mom said right before she
snapped this picture of my brothers and me in the water on this year's vacation to Silver Lake,
Michigan. As we smiled I'm sure both of my brothers, Jason and Nolan, just wanted to get back to
playing in the water as they were before. My dad was probably off drink in hand relaxing and
soaking in the rays. Ella, our dog, though was definitely barking and being a pain in everyone's
behind. And me, I was probably annoyed at yet another picture my mom needed to take. However
we smiled all happy to be in our favorite place, enjoying time together, and relaxing.
They aren't shown in the picture but to the right of us are beautiful mountains of sand that stretch for
miles and miles. Eventually they lead straight to Lake Michigan, a journey I have only ventured on
once a long, long time ago. All I remember was it being very far and getting a piggyback ride for
most of it. Now this year as yet another dune day was coming to a close, it was like 7 or 8 o'clock at
night, we let Ella off her leash and followed her as she headed toward Sugarloaf, the biggest dune.
As she start to climb my dad joined her because she obviously can't go alone. They both stopped
many time struggling up the big mountain but after quite a bit of time they both made it up. This is
the first year Ella has made it to the top. We were all impressed because usually she gets bored
halfway up and wants to turn around.

Essay On Water Pollution
Water is one of the most needed elements for survival on Earth. All organisms contain it, drink it or
live in it. Water pollution has been an increasing problem for many generations. Pollution has been
around for more than a century, but people did not believe that it was a real threat until it became
more aggressive over the years. Pollution comes in many forms such as agricultural, runoff,
industrial, sedimentary, animal wastes, etc. For example, many industries began using synthetic
materials such as plastics, polychlorinated biphenyls (PCBs), inorganic pesticides, and among other
substances that many cases lead to contamination water systems. These materials are not only toxic,
but they are also detrimental to the environment and...show more content...
A nonpoint source is pollutants enter indirectly through environmental changes such as fertilizer

Essay On Water Science
The discussions on the experimental design methodology of this paper will focus on the
hypothesis that a lake is located directly adjacent to an agricultural field, then it will have higher
levels of phosphorous in the water than lakes located more than 500 meters from an agricultural
site. In general, water bodies that are located near agricultural grounds are likely to have their water
quality deteriorated compared to those far from farming land. In the context of this paper,
phosphorous in water near a farming area arises from a number of sources. These sources include
erosion from agricultural soils, as well as domestic, industrial and farm effluents such as silage
effluents, atmospheric disposition, and ground water discharge (Sliva &...show more content...
The location of the lake too near to the agricultural land makes it vulnerable to pollution due to the
numerous agricultural activities, thus greatly compromising the quality of water in the lake.
Methodology Random samples of water from taken from the lake, and others from a lake located
700 meters away from the agricultural farm. However, these samples featured different periods of
the year as a way of ascertaining whether the concentration of phosphorous in the water varied with
the level of farming activity. The intention here was to capture the pulses in phosphorous
concentration in the water as perpetrated by run–offs throughout the year (Sharpley et al., 2013).
The water samples were taken from different spots of both lakes and placed in clean polythene
bottles that were pre–rinsed and washed with acid to remove any contaminants, which would
otherwise interfere with the results of the experiment. These samples were then taken to the
laboratory for appropriate investigations (Macreadie, Hughes & Kimbro, 2013). Some parameters of
the samples, such as pH, temperature, transparency, and depth, were determined on the time of
collection. The rest of the parameters such as ortho–phosphorous and total phosphorous and water
hardness were determined in the laboratory (Sharpley et al., 2013). The data collected from the
water samples for the physicochemical parameters was presented in terms of mean values, and its
analysis was done on

Argumentative Essay On Water Pollution
In recent times, a popular issue that sparks much controversy amongst the population is Pollution.
Since the Industrial Revolution, pollution has been rapidly increasing, whether it be air pollution or
soil pollution, the effects are prevalent. From the Great Barrier Reef slowly dying, to the polar ice
caps melting to climate change, pollution has been much more noticeable than in prior times.
Although, it is clear that pollution is causing great issues for our environment, many fail to
acknowledge the issue and or simply overlook the issues, especially if they do not notice how these
issues affect them personally. These effects on our environment actually impact the human body and
can affect different systems within the body such as the respiratory, reproductive orimmune system.
An issue that deserves recognition would be that of the affects of water pollution and access to clean
water on the immune system. Water is an essential factor for the survival of human beings. As a
matter of fact, life can occur on Earth because of water. Although, waster is an essential to life,
there are many in have little to no access to clean water. Water is necessary because it can help
nutrients travel within the body as well as filter out the kidneys. If one was to drink polluted water,
then they are exposing their body's systems to harmful bacteria that can harm the different systems
such as the respiratory, immune and nerve system. Exposure to water pollution and lack of access to

Water Safety Reflection Essay
The goals and expectations I had for the adult swim lessons were to help adults reach a basic
understanding and skill level of water safety. From the start, I worked to ensure a clear portrayal
of by goals since, as Steven Covey and his fellow authors said in "The Power of Goals," "goal
setting is obviously a powerful process" (306). Planning and implementing my project took more
time than I initially believed on account of needing to secure pool space and at a time which
would work with both my swim coach's and my schedules. To start off, I put together a working
model for how to run it based upon the swim lesson program I work for, modifying for adults. On
the working model, I put floating as the first skill to learn and teach, then treading, being able to
move your way through the water and finally was endurance. These guidelines were set forth to
guide the instructors, yet not restrict them in what they can do, I told them they were not required
to follow them to the letter, as long as they are teaching the skills, David Rock talks about this in
"Scarf: A Brain–Based Model for Collaborating with and influencing Others" when he says,
"boundaries within which individuals can exercise their creativity and autonomy" (434). I ran this
model past my community partner and he approved it. Although we worked hard planning and
promoting the class via posters and online posts, only four adults showed up. Throughout the
project, I was in charge of making sure everyone working knew

Water Pollution In Florida Essay
Water is a necessity for human life and Earth's environment. As the Earth's population continues to
grow we continue to strain the Earth for its water supply. Water pollution is when there is a
biological change in the nature of the water biologically typically in a negative way. As water
pollution began as natural causes through animals and other environmental issues as the increase in
human activity over the years there was an expansion in water pollution. As the increase in
contamination is obviously due to the excess of human activity due to the earth's history it affects
them the most. With Florida being a highly populated state surrounded by large bodies of water puts
us at a greater risk of contamination. As Florida being a prime vacation spot the demand for clean
refreshing water should be high, but with the ongoing water contamination the likelihood of that isn't
very high. If this continues then Florida's being a beautiful vacation home would turn into an
environmental dump.
Many people do not acknowledge the importance of water in life and how polluted water can
become. The pollution of water in Florida is a factor that developed with time. Florida in the
beginning was completely underwater. Many settlers dug wells and built dams on the rivers to be
able to drink water (Florida's Water...2002). The population started to grow rapidly in Florida,
resulting in competition for survival.
Florida's population in the 1920's was about 970,000, the growth of the

Argumentative Water Essay
There is a water crisis which faces many parts of the world and it is a threat to survival of human
beings since humans are primarily dependent on water. Shortage in drinking water is beginning to
show its effects in first world countries, but is a current major problem facing lesser developed
countries which have not taken drastic steps to harvest water and purify it to make it safe for human
consumption. In developed countries the population growth has strained available water resources
and stretched the ability of governments and private firms to provide safe drinking water to the vast
majority of the population. Seventy one percent of...show more content...
Many populations, the majority being in Africa, face many water–borne diseases mainly due to
pollution of water resources. The option then becomes to either drink polluted water or not have
anything at all. Continual Human development such as population growth and industrial growth
have further drained water resources, causing a shortage of drinking water. As a result, there are
many conflicts over ownership of water resources and these lead to injuries or fatalities.(2) As
mentioned before, this shows why it is so important to find a solution to the issue of water shortage.
In the United States, the available water resources is also under assault. Half of water collected
and stored by existing infrastructure is usually used in the production of electricity. This forces
the population to use and divide what little there is left. This has always been a "good enough"
approach until now, when water prices and population is on the rise.(3) There are already calls for
charging water resources in order to increase efficiency of use.(3) Water protection is already being
carried out and has been for years, but there is still water pollution occurring within the United
States. After the Civil war, America strived to provide its population with clean water

Water Quality And Quantity Of Water
Water Quality and Quantity
Water quality focuses on the physical and chemical makeup of water samples (toxicity); water
quantity speaks to availability of water (scarcity) for human needs and industry. Linking water
quality and quantity is sustainability. An abundance of water does not necessarily ensure it can be
safely consumed if it's contaminated by sewage and/or industrial activities. In 2003, the United
Nations (UN) created the inter–agency "mechanism, UN–Water, to identify water quality and
quantity issues, facilitate the exchange of information, and develop programs to facilitate water
conservation. The UN–Water's activities are tied to the UN's eight Millennium Development Goals
(MDGs) established in the year 2000. Water management, access and quality are tied to each of the
MDGs. (UN–Water, 2012; Water Quality, 2014; Water Scarcity, 2014).
Two Water Facts
I was surprised to learn that by the year 2025, two–thirds of the World's population may experience
water stress (Water Scarcity, 2014). Based on the four year drought in California (United States), I
would surmise that that water scarcity will not be limited to developing nations. I was curious to
learn more about pharmaceutical contamination in municipal water supplies, which is at time, a hot
topic covered by the new media. I was surprised to read in a 2012 World Health Organization
(WHO) report, Pharmaceuticals in Drinking Water, that while recognizing there is limited data
because programs to monitor

Persuasive Essay On Save Water
Water is something no one can live without. In fact, human bodies are about sixty–five percent water.
Therefore, water conservation is a project everyone should be willing to participate in. Specifically,
in the Logan, Utah area, water conservation is an important topic, as the citizens use water every
day. "In an interview with The Herald Journal, USU sociology professor Douglas Jackson–Smith
said the city's water concerns have the potential to increase, based on Logan's anticipated
population growth by 2050" (Peikes). There is a growing concern about the amount of water the
city will have or be able to produce for the growing population. Although it is important that each
citizen is staying hydrated and being hygienic, people do not need to use so much water in doing
so. Many people have cut back on watering their lawns, or started to take shorter showers, but there
are more options to choose from and ways to conserve water. This problem is solvable, if only more
people would participate and take steps to conserve water.
First, the citizens of Logan, Utah should act in conserving the water supply in Logan for now and for
the future. The actions they can take are simple, and come down to the basic rule "stop using so
much/ wasting water". Each individual resident can take steps to conserve water within their homes.
That is usually the easy part. The hard part about conserving water is getting businesses and the city
itself to conserve water. Businesses waste a substantial

Water On Mars
In the article "Mars Shows Signs of Having Flowing Water, Possible Niches for Life, NASA Says"
written by Kenneth Chang the central idea is that there is a probability of life on another planet
other than Earth. The reason this article is important to us is because with these findings,
researchers will be eager to follow up on the discovery so that we can find out if the probable signs
of liquid water flowing mean that life could sustain on Mars. For many years scientists have been
interested in knowing whether or not there is other life and if there has previously been life on other
planets. With this discovery, we are getting closer to coming up with possible answers.
In the past year, researchers have found probable signs of liquid water flowing on Mars' surface,
such as waterlogged molecules, leading to the idea that Mars could possibly sustain life. Hydrated

Or why do we care that there could have been life before us on another planet? The answer is simple,
we know that water is essential to life, so water on Mars means life. Mars is the only planet that we
have discovered with signs of water, which makes this an important discovery. Mars is also very
close to Earth in the solar system, which makes this relevant to us. If we could find evidence of life
on Mars it is possible that we could use findings to our benefit, we could use this as a reason to keep
looking further into Mars. If the research of Mars continued, researchers could dig deep into the
layers of Mars and possibly find even more clues all leading to the hopeful discovery that life does
live or has lived on Mars. It is possible that one day in the future NASA will be able to send an
astronaut to Mars. However, with everything stated above, there still needs to be more research
done to find out if life could really sustain on

Persuasive Essay On Water Of Water
Introduction The use of chemicals in a school environment cause several issues in not only our
health, but our watersheds as well. The chemicals in use in our school are those that cause
damage to our health, they cause this damage with ingredients that are not completely user
friendly. A watershed is a drainage basin, which is a natural depression in the earth's surface,
usually containing water, and a divider that separates different areas. Here in Colorado we have
two main watersheds, but we also have several streams considered watersheds. We are in the
Cache La Poudre watershed. A watershed is the transport of different water and it is what is used
to drain water into other basins, or oceans or any bigger water masses. It has stream valleys that
bring water to other bodies of water, in which evaporate and return to the top. This is a constant
stream in which is basically recycling water, so we want to keep the water healthy and ready for
us to use. In a certain quote, we understand the dangers of what we do to our watersheds with
urbanization,"flooding becomes more prevalent as the area of impervious surfaces increase."
(Perlman, 2016). This quote is saying that the more surface area that was given, such as parking
lots, the more runoff comes from our flooding periods. This could be a danger in our school
environment, because we use several chemicals as cleaners. I found greener cleaning supplies from
not only our current distributor, but one of distributor that

Water is an essential ingredient for the existence of life as we know it. Biochemical processes

This results in a concentration of negative charges nearer the oxygen atom and thus further from the
positively charges protons that make the nuclei of the hydrogen atoms. The bond formed is
intermediate between a fully ionic bond and a purely covalent bond. There is a separation of charges
but not complete as in the formation of ions. The partial charge that is produced is symbolized by
d. In Water, one side of the molecule, where the hydrogen atoms are, will be partially positively
charged. The other side with the unshared pairs of electrons will be negatively charged. As a whole
the molecule is polar. So it can be said that the water molecule has a polar covalent bond. The
polarity of the water molecule makes mutual attraction between water molecules possible.
The Hydrogen Bond
Each molecule has a d– and d+ region. The attraction occurs between the d– and d+ regions
(remember unlike charges attract). This means that each water molecule attracts four other water
molecules to it. The hydrogen atom is attracted to the oxygen atom of the adjacent water molecule.
Each oxygen atom can associate with two hydrogen atoms of other nearby water molecule through
its unshared pair of electrons. The force of attraction between these polar molecules is not as strong
as a covalent or ionic bond but strong enough to be significant. It is important enough to be called
the HYDROGEN BOND.

Essay On Water In California
California has always had a warm climate, yet its supply of water has rarely been affected. In 2014
California's water shortage issue truly began. Due to low amounts of snow in the winter in recent
years, California has tried to equal out these shortages by drilling water from underground aquifers.
Yet, underground aquifers recharge much slower than surface water sources. California has already
made significant drawbacks to attempt to limit the amount of water they use, so these aquifers can
recharge. But still resources continue going down and the Central Valley Aquifer's water level is
rapidly declining. Luckily, on April 7, 2017 the drought stage of emergency in California was ended.
Yet the issue isn't truly resolved. Glen MacDonald...show more content...
440). The main way for most aquifers to be recharged is through surface runoff. The rainfall sinks
into the ground and percolates or accumulates to a common place (usually an aquifer). Yet this
process takes lots of time. Scientists believe it may take centuries to refill some of the deeper
aquifers. Water travels especially slow underground. It could take water up to 500 years to travel 15
meters. Aquifers are depended on for roughly 40% of California's water supply. This number can
escalate to 60% during droughts such as the one that just occurred. Yet, humans have limited control
on natural events, so this only reinforces the importance of managing water wisely. Recently
California's government has begun to focus more on sustaining and restoring the water supply.
Dale Kasler (2016) articulates in his article some of the steps they have decided to make to solve
this serious issue. The government has made the following investments: "$415 million for
watershed restoration and other environmental aid for Lake Tahoe; up to $335 million for two
proposed reservoirs in California, including the Sites reservoir north of Sacramento; $880 million for
flood–control projects on the American and Sacramento rivers in Sacramento; and $780 million for
flood–control projects in West Sacramento" (para. 10). This could be the first step to restoring the
water to California. But these

In David Foster Wallace's graduation speech, This Is Water, he uses logical and emotional appeals
to discuss the importance of critical thinking. Wallace uses the term "conscious" to signal critical
thinkers, while those who do not think critically are referred to as "unconscious." Wallace's main
argument is that a person has the choice to think critically and should do so every day. Wallace's
analysis of consciousness and unconsciousness focusses too heavily on the logical and emotional
appeals and ignores the possible ethical arguments that support the development of conscious
societies, such as activism. In doing so, Wallace favours the self–interested members of the audience

Through proving that we are not always correct, and reminding the audience that different people
can have different views of reality, Wallace is able to use logical reasoning to show that humans
have the ability to change their perspectives. Wallace's use of negative emotional words and the
parable of the college graduate who goes grocery shopping evoke negative emotional responses to
unconscious thinking, resulting in a strong, convincing emotional appeal. Throughout the speech,
Wallace stresses the tediousness of everyday life, dwelling on negative emotions such as "tired,
hurried," "somewhat stressed," and "pissed and miserable." Through these negative words and
more, Wallace shows how awful life is for unconscious people. In addition to the negative
emotions, Wallace implicitly refers to suicide in phrases such as: "...[living] in the day to day
trenches of adult existence, banal platitudes can have a life or death importance." By this statement,
Wallace is arguing that unconscious thinking can lead to death. He also claims that consciousness
is a way "...to keep from going through your [...] adult life dead, unconscious, a slave to your
head," and that "most of these suicides are actually dead long before they pull the trigger." This
selection reinforces the negativity of unconsciousness (through the words "dead" and "slave") and
Wallace's claim that a person can become a

Salt water refers to water that contains dissolved salts, known as saline water or seawater, water
from oceans or seas. It is a home to varieties of aquatic animals, for example, fishes and snails.
Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh
water they can not adapt the environment led to die to them. This essay aims to discuss the
importance of salt water and the sub– types namely ocean, sea, and coral reefs. It will also show

Coral reefs are home to a variety of tropical or reef fish, such as the parrotfish, angelfish,
damselfish and butterfly fish, and over 4,000 species of fish inhabit coral reefs. The fish species
that inhabit coral reefs are able to coexist in such high numbers because any free living space is
rapidly inhabited by the first type fish larvae that occupy it. These fish then inhabit the space for the
rest of their life and the species that inhabit the free space is random.
Due to their vast biodiversity, many governments world–wide take measures to protect their coral
reefs e.g. in Australia, the Great Barrier Reef is protected by the Great Barrier Reef Marine Park
Authority.

Major plants and animals found on Coral Reefs.
Thus, primary productivity on a coral reef is very high and producers in coral reef communities

called turf algae, although scientists disagree about the importance of these particular organisms.
The threats to the world's coral reefs are:
Coral reefs are in crisis, dying at an alarming rate worldwide with and an estimated 25% of coral

Water Inequality Around The World
Around the world there are many inequalities which can affect ones happiness, health and prosperity
in life. One inequality affecting peoples well–being is the inequality of water. Water inequality is a
result of many factors and indicators such as which has been impacted by multiple factors such as
pollution, high population rates, geographical barriers and climate change. A massive factor in the
inequalities of water is the pollution, up to 90% of waste water in developing countries flows
untreated into rivers, lakes and highly productive coastal zones, threatening health, food security and
access to safe drinking and bathing water. Another factor is high population rate, every year the
demand for water has been increasing. Due to the increased

So shouldn't we be more concerned about keeping this small amount of water the most healthy and

unregulated chemicals in our drinking water every single day. Thousands and thousands of
chemicals are made and proposed to the EPA every year to be tested and decided whether or not
they would be harmful to humans and to publish their effects. This paper will outline regulation on

The EPA also uses the Unregulated Contaminant Monitoring Rule to collect data for contaminants
that are suspected to be present in drinking water and do not have health–based standards set under
the SDWA. This provides EPA and others with scientifically valid data on the occurrence of these
contaminants in drinking water, allowing the public to know the effects and health risks of these
unknown chemicals. But, the EPA is also restricted to how many chemicals it can monitor and
regulate for a given time. The SDWA amendments of 1996 provide for monitoring of no more than
30 contaminants per 5–year cycle and also monitoring only a representative sample of public water
systems serving less than or equal to 10,000 people. The EPA is also required to publish a list of
contaminants every 5 years under the SDWA, and directs the Agency to consider the health effects
on humans and occurrence information for unregulated contaminants. The Agency makes decisions
to place contaminants on the list that present the greatest public health concern related to exposure
from drinking water. It uses this list to make regulatory decisions regarding contaminants.
Every day we are exposed to contaminants in drinking water and are most likely not even aware of
the harmful effects to human health and to the ecological systems as well. One harmful effect is the
use of perfluorochemicals (PFCs) found
