Drinking Water Supplies And Natural Aquatic Systems

Drinking Water Supplies And Natural Aquatic Systems
Sydney Water Supplies By: Dilu Arulanandarajah Describe why drinking water supplies and natural
aquatic systems are subject to regular monitoring. It is very important for that water quality is
monitored in water supplies and natural aquatic systems because it an essential resource for living
organisms, industrial process, irrigation and domestic use. Water quality monitoring can be defined
as a process used to monitor surface and ground water by using different methods to gain
information about a body of water. Monitoring water quality is important for a number of reasons.
Firstly so that trends in the water quality can be detected. These trends are important in in
determining the quality of water such the mineral content within it. ... Show more content on

These pollutants can also be consumed by people and animals which will lead to sickness and
disease. By monitoring the water quality pollution and contamination can be prevented in its early
stages and which can also improve water quality. What and where is Sydney's Catchment area?
Sydney Catchment Authority defines a catchment as "an area where water is collected by the natural
landscape.' When water is collected by dams or weirs or by tapping into ground water it is called a
water supply system. Dams are usually built are large rivers to give a more permanent supply of
water. There are 11 major dams in Sydney that store water in five catchments which are
Warragamba, Shoalhaven, Upper Nepean, Woronora and Blue Mountains. These 5 main catchments
of water cover 16.000 km2 of land and hold 2,500 billion litres of water while providing 4 million
people with water. Warragamba Catchment Warragamba Dam is the biggest catchment in Sydney
and voters about 9,500km2. This catchment is mainly used for cattle and sheep grazing because of
the wilderness in the centre of the catchment. More than 25% of the catchment is protected from
human activities for over 70 years because it is home to the spotted–tail quoll, eastern pygmy
possum, Rosenberg's goanna and three threatened species of owls. The dam is created by damming
the Warragamba River and flooding Burragorang Valley. This makes the lake four times the size of

Characteristics Of A General Green Roof Water Recycling...
This technical description will depict the parts and characteristics of a general green roof water
recycling system.
Introduction
Audience
This description is aimed toward the general public to be informed on this form of Green
Technology and how it benefits our environment.
Purpose
Sustainable and environmental technology, also known as "green" technology has become a trend in
the design world as our culture has began moving into this era of "going green." This roof system is
an example of green technology being implemented into buildings and structures that the average
person sees on a day–to–day basis. Essentially this description will help the general public will gain
knowledge on stormwater reclamation through green roof technology. The audience will also be left
with the ability to identify this technique on buildings that they might possibly see everyday.
Topic
Green roofs, also known as "living roofs" are a restorative and protective system applied to the roof
of buildings or structures. Essentially it is an extra vegetative layer on the roof of a building. Green
roofs collect rainwater to later be reused to run specific facilities. This rainwater is then run through
a series of tanks and filters before being reused as greywater. Greywater is non–potable water that
can be used for things such as flushing toilets and crop irrigation.
Overview
This description depicts the characteristics of a green roof and the process of recycling and
reusingthe water that

Global Warming And Its Effects On Water Storage Systems
Have you ever imagined picture of California arid and lifeless in the next few years because of the
drought? That is likely to come true if we don't know how to use water wisely. Now in California,
The valleys become barren and rivers and lakes are gradually drying up due to lack of
water.Because California is in serious shortage of water and the water reserves are being depleted
due to the prolonged dry heat and it has been happening for several years and have more negative
developments. Since records of researchers that 81% California in an " extreme drought " and the
main cause of droughts are climate change, overuse of groundwater resources and the issues of
water storage systems. Firstly, Human is cause climate changing and also contributed to raising
temperatures and dryness in the all world, especially made extreme drought in California. Global
warming caused effects to weather variations and dramatically amount of rain and snowfall in
California. With no winter snowpack to recharge its rivers and little rain to replenish groundwater

Columbia University said average temperatures in California have increased by 2.5 degrees
Fahrenheit over 113 years, and theorized that heat and dryness have intensified the state 's drought
by up to 25 percent ". (Fears, para.3) Addition, mountain snowpacks are frozen reservoirs, their

The New York City Water System Then and Now
New York City has one of the most top quality drinking water and is called "the champagne of
drinking water"[13] which is due to its unique water treatment system that consists of a vast
reservoir system. A reservoir is a natural or artificial source of untreated water that can be found
underground or at ground level that can include water treatment and associated equipment (pumps
and piping systems).[1] There are three major watershed systems in which New York receives its
water which are The Croton System, The Catskill System, The Delaware System. The reservoir
systems pump approximately 1.1 billion gallons of fresh and clean ... Show more content on

Further population increase and the expansion of New York City to include five boroughs amplified
the need for more clean water circulation. In order to find new water sources the Board of Water
Supply built facilities in four watersheds that is now known as the Catskill System (which includes
the Ashokan Reservoir and Catskill Aqueduct). The Delaware System was fully constructed in 1944
which receives water from the Delaware River tributary. Located in current day New York Public
Library there once housed one of NYC's main water supply systems called the Croton Reservoir
(Murray hill reservoir). Built in 1842 in a style of an Egyptian Cornice it had an area of four acres
and held a capacity of 20 million gallons. As a result increases in population between 1840 and 1870
other reservoir system were built in place of the Croton Reservoir and it was shut down in 1890.[4]
NYC Reservoirs today
The NYC drinking water system is gravity driven and is sourced from 19 reservoirs and three
controlled lakes in a 1,972 sq mi watershed and has a storage capacity of roughly 580 billion
gallons.[5] During drought water is exchanged from one water system to the other.
The Croton System has 12 reservoirs and three controlled lakes that are positioned in Westchester,
Putnam and Duchess Counties. The newest Croton Reservoir

Project Water Level Indicator With Automatic Water Pump...
Water is the most important issue in our day to day life. But it is very pathetic when the owner of the
house faced that the water tank be empty without any alarming. The project is to design water level
indicator with automatic water pump controlling system. water level sensor is been made for sensing
water level accurately. Microcontroller is used to control the overall system automatically that
reduces the design and control complexity. Microcontroller takes input from the sensor unit which
senses the water level. After processing input variables, resultant output decides the water pump's
action (on/off) with respect to current water status of the tank. A display unit indicates the status of
pump and water level. The device also monitor the state of level of water whether it is stable,
increasing or decreasing with what velocity. It also stores the total time of pump being kept ON. It
also keep monitoring whether the pumping is working well or not. While Keeping the motor ON it
detects whether the motor pump is working well or not every minutes. If the level is increasing or
decreasing in each minutes then the indicator shows the motor pump is working well else after three
minutes if the level remains stable then it shows there is a problem in motor. Thus it also monitor the
working performance of the pump Introduction
An Water Level Indicator may be defined as a system by which we can get the information of any
water reservoir. Water level indicator system are quite

Prepaid Water Meter System
There is an increasing awareness in South Africa that water is limited and that careful management
should be applied when dealing with this scarce resource. In recent years, we have witnessed
recurring protests in townships and informal settlements around South Africa arising from disputes
over housing, water, and electricity, which are often accompanied by violence against material
infrastructures (ripping out of pipes and meters, spilling sewage and trash outside municipal
buildings).This essay will argue for and against the prepaid water meter system with regard to its
advantages and disadvantages as viewed by the people verses the government. What is a prepaid

Helpwriting.net ...
It is largely argued that the prepaid water meters are usually not promoted in wealthy areas. The
meter system violates the right to water; the human right to water has been recognised in the United
Nations International Covenant on Economic, Social and Cultural Rights. Yet, prepaid water meters
abuse the core of this international agreement by denying access to clean water to those in most
need. Instead, prepaid water meters force poor families to use unsafe water sources once they lose
their ability to pay. Lastly, I strongly believe that the prepaid water meter system undermines public
health; it forces households to decrease their consumption of water and to make difficult trade–offs
between food, medicines, school fees, transportation and other essential goods and services and the
consumption of water. As a result, families survive on less than the World Health Organization
recommended minimum water consumption for life of at least 25 litres of water per day for basic
survival (100 litres per day is needed to sustain human development). A lower consumption of water
severely limits the ability of development and creates an undignified situation for the poor. In the
United Kingdom, prepaid water meters were associated with an increase in dysentery when families
self disconnected after being unable to pay for service. In South Africa, Kwa–Zulu Natal, 113,966
people were infected with cholera after

The Portland 's Water System Essay
I have learned about the Portland's water system in the first of a few weeks. I have learned the
Portland's water resources, water quality management, history of water system, water transportation
system, and water issues in Portland area. Now, I compare Portland's water system to another city in
the United States. I pick up Seattle's water system because I lived in Seattle for two years before I
move to Portland, and I'm interested in the Seattle's water system. In this journal, I write about the
following sections: History of Seattle's water system, water resources, water quality management,
water transportation, water issues in Seattle, and conclusion (similarities and differences between
Seattle's water system and Portland's water system). History: In the 19th century, Seattle's water
came from springs, wells, and private water companies. However, the population of Seattle
increased in the late 19th century, and the demand for water supply also increased. In June 6, 1889,
there was a large fire what is called "Great Seattle Fire" in downtown Seattle. After this event,
government decided to establish municipal water system. After this plan was approved, the
government constructed the Cedar River water system. On January 10th, 1901, water from the
Cedar River flowed into Seattle's water system for the first time. A pipeline channeled water to the
Lincoln reservoirs and the Volunteer Park on Capitol Hill. When the water system constructed, the
water system capacity was 23.5

Argumentative Essay: Storm Water Remediation System
During my senior year four of my friends and I entered into a storm water remediation system
design competition that was sponsored by the EPA. The point of the competition was for college
students, with the guidance of professors, to create a hypothetical storm water remediation system
that would benefit our college campuses. For our project, we created a system that would divulge,
filter and use the storm water runoff. This water would have otherwise flown into a drainage pool
owned by the city of Burlington Vermont. This drainage pool consistently would fill up with
sediment and cost the University of Vermont big money to clean. Our plan was also designed to help
curb the amount of pollutants like car oil and liter, that is carried by storm

Fluoride Water System
Understanding Fluoride Water Systems
Summary: The article highlights that there are certain water systems which use advanced technology
to get rid of harmful contaminants from water like fluoride. This is useful to attain pure drinking
water.
One of the main contaminants that are found in water is fluoride. One should know that the greater
amount of consumption of fluoride can be hazardous to health, so one has to keep in check the
consumption pattern. If you want to get rid of this from your drinking water, then you should install
a water filter that will remove the fluoride, and give you pure drinking water, that is safe from
harmful chemicals and contaminants.
The question that you should ask yourself before purchasing a water filter to ... Show more content
on Helpwriting.net ...
You can purchase an ion exchange based filter that will remove fluoride unlike simple distillation or
chlorine purification process. Again, you can also buy filters which make use of AquaMetix, a new
proprietary filtration technology which removes almost 50–85% of fluoride.
Some companies sell their products claiming that regular carbon filters will remove fluoride, but this
is not entirely correct. Also, you should not be fooled by single multi–media cartridge units that
contain a small amount of media in addition to carbon. A cartridge of 100% fluoride removal media
is needed to allow proper contact time for effective fluoride removal from the water.
The water system should remove chlorine, lead and mostly all other chemical and non–chemical
contaminants, but at the same time should ensure that the essential minerals are not filtered out and
we get pure drinking water. Take time to find out the most suitable filter at your home or office for
healthy drinking water. You should not hasten in these matters, and find out the system that will
make obtaining fresh fluoride free water

Contaminants In Water System
Few people give much thought to what's in the water that comes out of their faucets until a funny
smell or color alerts them that more than just water is coming from the tap.
Unfortunately, many pollutants don't taint drinking water with foul odors or colors, leaving many
people unaware of the contaminants their families are likely consuming on a daily basis.
Fortunately, Anderson Water Systems in Rochester, New York, has helped homeowners in their
region filter and purify drinking water for more than 60 years.

Roman Water System Essay
During the ancient Roman time period, there was a problem towards water. The Romans used water
every day in fountains and for recreational uses. But how could this water be transported for
everyday use and then how was the water to be disposed of? The Romans managed to find the
solution to these problems. They used the idea of the aqueduct to transfer the water from sprigs to
Rome. Once the water was in Rome, it went right to use, either by sending the water directly to a
bathhouse to be heated up by a hypocaust, or to a fountain to be seen by all the people of Rome. The
water would then be disposed of and travel to the sewer system where it was disposed of. But how
did these revolutionary water systems work and what good did they bring to ... Show more content
The sewer system would collect water from baths, latrines (a public pay toilet), palaces, fountain,
and other urban runoff (Hasan). From here, the sewers would flow through town to either the nearest
river or to out onto fields for irrigating and fertilizing soil (Wikander 176, 655). However not every
Roman citizen could afford the cost of a bath or bathroom in their house, so they would be forced to
either use a latrine or a chamber pot (Hasan). A latrine was a public pay toilet and a chamber pot
was a pot where bodily excretions went (Hasan). The chamber pot became a problem as most people
became too lazy to properly empty them, so they dumped the chamber pot out of the window. With
this problem rising, the Romans decided to use an open sewer system as well with the regular sewer
system (Wikander 168). The open sewer system is exactly how it sounds, it's an open sewer where
sewage runs through town to the nearest disposal sight. This helped with the disposal of the chamber
buckets. Later an emperor named Vespasian came up with the idea to collect all the urine (Hasan).
Vespasian had discovered that the ammonia in urine had cleaning properties, so he collected the
urine to wash clothes

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

Systems For Humans Can Not Function Without Clean Water
Many systems for humans would not function without clean water, such as: water supply, sanitation,
agriculture, and health, which are dependent on fresh water supply. We also often get our drinking
water from lakes and rivers and with healthier water systems come a healthier food chain. This is
because all animals and plants depend upon the water on the earth. There is a connection between
the changes in fish habitations and the composition of species in these habitats (Komatsu,
Fukushima, and Harasawa, 2007), and healthy water systems. Increased temperature due to global

The main source of dissolved organic carbon and other organic matter for surface water is soil
leaching (Delpla et al., 2009). The rate of leaching increases with the amount of rainfall, high
temperatures, and the removal of protective vegetation. Increased rainfall and drought have affected
runoff distributions and therefore is a major influence on dissolved organic carbon levels because
dry–wet cycles have shown increased organic carbon following rewetting (Evans, Monteith, and
Cooper, 2005)(Kundzewicz, Mata, Arnell, Döll, Jimenez, Miller, Oki, Şen, Shiklomanov, 2008). The
increase in dissolved organic carbon in surface water shows indications of more acidity as
biodegraded organic materials in natural substances are inherently acidifying agents (Erlandsson et
al. 2011). Evidence collected indicates that the organic acidity is also affected by land use (Guo and
Gifford 2002) and climate changes (Worrall et al. 2004). However, dissolved organic carbon
supports growth of microorganism and plays an important role in the global carbon cycle. It is an
indicator of organic material amounts in water, as well as supporting land processes, within soils and
wetlands, of organic matter. Although there are benefits of dissolved organic carbon in soils and
wetlands, the potential when an abundance is leached into surface water to interfere with health
precautions, other organic and non–organic material, and microorganisms has caused these rising
levels to

The need for portable water purification systems across America is rapidly growing. Individuals all
over the world invest in portable water filters for various reasons. Outdoor enthusiasts, survivalist,
and individuals living in third world countries; consider it an emerging necessity.
Lifestyle Trends
Outdoor Enthusiast:
Hunting, fishing, camping, and backpacking are just some of the activities that an outdoor enthusiast

Survivalist:
The Survivalist is another group of individuals that highly value the benefits that portable water
filters offer. A survivalist is "someone strongly determined to survive".
(yourdictionary.com/survivalist) They are constantly prepping for uncanny events that they suspect
may occur. All survivalist share a deep desire to live, therefore overcoming obstacles to survive is
taken to an extreme. According to Dr. Stirling Silverman, the author of a survivalist blog, states that
disaster can be divided into two broad categories. First, are disasters resulting from human activity
and second are natural disasters. Terrorism, war, water pollution, and an economic collapse are just a
few tragedies resulting from human disaster. Hurricanes, earthquakes, epidemics, and droughts are
just some examples of natural disasters. (thenewsurvivalist.com) Survivalists also spend their time
studying and becoming knowledgeable on different types of scenarios. Preparing survival kits is a
top priority among these individuals. "Generally, knowing how to make a survival kit is good to
study up on prior to any disasters, because they have been proven to save lives when needed".

Because survival is essential to these individuals they prepare bug out bags. These bug out bags
contain: flashlights, emergency food, sleeping bag, canteens, knife, water, etc. Water is a very
important essential to have in the survival kits. Including a portable

The Water Systems And Landforms
Introduction While studying water systems and landforms in our lab, we begin to wonder about
certain climates and regions. In this paper, I will discuss the water systems and landforms found in
Baton Rouge, Louisiana, as well as two other cities in the United States. I will explore the amount of
water that comes and leaves their systems, as well as the natural landforms that occupy their regions.
Background Throughout this paper, there are terms you will need to know. While discussing the
water systems of Baton Rouge, we will discuss both precipitation and evapotranspiration.
Precipitation is the process of weather in the form of rain, snow, hale, or sleet falling to the ground.
Evapotranspiration is the process in which water is transferred from the land to the atmosphere by
evaporation (merriam–webster.com). Also understanding what a deficit is, or when the amount of
water being provided is too small an amount. While discussing the landforms of Baton Rouge we
will discuss the Topography, or the arrangement of the natural and artificial physical features of an
area (merriam–webster.com). Methods Data Baton Rouge, Louisiana is located at 30˚27'N, 91˚08
and has an average elevation of 51 feet above sea level. It is located in the southeastern part of the
United States. To establish data, I used the water balance charts that we completed during lab 6. This
analysis provided a collection of the average annual rainfall in inches and as well as the potential

Test The Water Usage Of The Smart Agricultural System
To test the water usage of the smart agricultural system, data was collected for the three different
types of algorithms implemented for this project: timed based, reactive, and proactive control of the
environment. The timed based algorithm turns the water pump on based only on the time of the day.
The reactive algorithm turns the water pump on only if the soil moisture falls below a certain
threshold. The first two algorithms only consider one type of data for their algorithms, either time or
soil moisture. Comparatively, the proactive algorithm actively monitors the environmental

This can be compared to high temperatures of 22 degrees Celsius and low temperatures of 18
degrees Celsius in the indoor environment. The reduced temperature variation helps to protect the
plants from the extreme weather conditions that the proactive, smart algorithm is able to compensate
for. However, since extreme environments would be difficult to reproduce accurately, this factor was
not considered for this test. Additionally, because the temperature variation would be applied
equally to each of the environments, it was deemed a non–significant factor for the purposes of this
test.
Rain however, was deemed a significant factor for this test. This test is centered on the water usage
of the system and as a result, it is important to see the effect of rain on the system. To accurately
simulate rain, 20mL of water was dispensed to each of the environments on the 3rd day of the test.
The water was dispensed using a measuring cup containing the set amount of water. The weather
data was also spoofed to change the weather status to rain. This was accomplished by replacing the
weather JSON file that would have been requested from openweather.org, with a fake weather JSON
file with the spoofed values. Finally, it should be noted that the sensor module pushes new data to
the Webserver at a rate of one packet every minute. Since the Webserver only updates the turn water
on command when new data is

California Water Irrigation System
Resource: Water; Country: United States of America; Activity: Water Irrigation
The main goal of this essay is to understand the impacts of the water irrigation system, within
California, United Sates. And discuss solutions that could reduce the impact on the biophysical and
socio–economic environment.
Key Issues: (Biophysical): Due to the water irrigation system that has been set up for many years in
California it has caused a large ground water depletion in areas, such as the Sierra Nevada. It now is
causing animals like the Southwestern Willow Flycatcher species to become endangered.
(Socio–economic): Water wastage is now proving more difficult for farmers to farm in the
California area. All from the fact that, within irrigating the water,

Supply Irrigation Water Irrigation Systems
Increasing threats of freshwater shortage, reduction in arable land, and more frequent and severe
droughts due to climate change has stimulated research into water–saving irrigation strategies
aiming at producing more 'crop per drop' (Morison et al., 2008). The trend in recent years has been
towards conversion of surface irrigation to drip irrigation to improve water use efficiency, plant
quality and, crop yield. Drip irrigation systems have increasingly been used to supply irrigation
water, fertilizers, and pesticides to a wide range of vegetables, field crops, and fruit trees due to their
ability to enable highly localized application of water and nutrients to crops (Kandelous et al., 2011;
Selim et al., 2013). Drip systems can achieve ... Show more content on Helpwriting.net ...
Saito and Kitahara (2012) used ground penetration radar to predict the changes in water content
under subsurface drip irrigation. Studies also used disturbed soil samples by gravimetric method
(Al–Mefleh and Abu–Zreig, 2013; KUMAR et al., 2015) and point based soil water sensors such as
TDR (da Silva et al., 2009; dos Santos et al., 2016) and capacitance probes (Fernández–Gálvez and
Simmonds, 2006) to estimate SWC variations under drip irrigation. Most of these studies have
investigated two dimensional (2D) wetting patterns changes while three dimensional (3D) wetting
patterns could provide more insights into the changes of wetted radius and depth under drip
irrigation. This is due to the fact that spatial variations in soil properties induce spatial variations in
water distribution patterns between drippers (Or, 1996) and consequently sensor placements to
detect wetted soil volumes around drippers become challenging. Because it requires large number of
measurement points distributed vertically and horizontally around an emitter to monitor variations in
wetting patterns which is laborious and time–consuming and practically infeasible sometimes if
point based sensors used. Therefore, it is necessary to explore alternative soil water sensing
techniques which could provide spatially dense measurements at small to field scales.
Distributed temperature sensing (DTS) systems are optoelectronic devices which

Sanitation Practices And Sustainable Water Systems
This paper explains the issues involving the Earth's most vital resource – water – and how problems
with access to it are on the rise due to a lack of sanitation practices and sustainable water systems.
Especially in developing countries, preventable diseases have become a top 10 global killer,
claiming the lives of nearly 730,000 innocent people per year (Water.org, 2015; Prüss–Ustün,
Bartram, Clasen, et al., 2014). As the world's population's need for water increases and the amount
of water on Earth remains constant, different issues stand out regarding the quality of water
resources. In Western societies, people pay little attention to the issue of water scarcity, yet, in the
developing world, access to water is a daily struggle ¬– ... Show more content on Helpwriting.net ...
(Water.org, 2015; World Health Organization & UNICEF: Joint Monitoring Programme, 2012).
When people in developing parts of the world do find water, many times it is not from a clean
source.
The lack of safe water supplies and abundance of preventable diseases that result have together
become one of the modern world 's top 10 global killers (WHO, 2015). Water–related illnesses claim
the lives of more than 2,000 people per day (Water.org, 2015; Prüss–Ustün, A., et al., 2014). A
recent United Nations Educational, Scientific and Cultural Organization (UNESCO) report states
that 10% of the global disease burden could be reduced by improving water supplies, sanitation and
hygiene practices, and water resource management in these areas (World Water Assessment
Programme, 2009, p.88).
While the costs associated with the loss of human life are immeasurable, the World Health
Organization (WHO) estimates unsafe water and lack of sanitation costs $334.5 billion across the
globe annually. WHO also estimates a one–time cost of $540 billion to secure safe water and
sanitation (Hutton, 2012). Because economic gains would likely recoup in about two years, it is in
the world's best interest, from an economic and humanitarian standpoint, to address the water supply
and sanitation issue.
However, in 2012, United Nations (UN) member states only committed $10.9 billion toward the
United Nations High Commissioner for Refugees (UNHCR) WASH program,

A Brief Note On The Water Treatment Systems
Water treatment systems The groundwater source is from GoldCentury gold mine, whereby excess
groundwater is pumped out of mine at a maximum volumetric flow rate of 477L/s. It contains
contaminants such as volatile organic compounds (VOCs), heavy metal impurities, sulphates,
bicarbonates, microorganisms, dissolved minerals and objectionable gases, but focuses on the
removal of dissolved inorganic contaminants such as calcium and iron. The most prevalent
dissolved minerals which are Calcium and Magnesium, also known as hardness, can be removed by
precipitation, requiring softening steps. The purification system designed is based more on
efficiency over cost effectiveness. The purpose of treating the groundwater in this assignment, is to
purify it to drinking standards to hydrate mineworkers underground during heated, intense mine–
work operations, and for operating certain equipment and tools. Figure 1: Mine groundwater
treatment plant schematic Figure 1 shows the following unit operations: A settling tank is installed
to allow large particles such as to settle so that they can easily be removed. The retention time is
around 30 minutes or 0.5 hours. Aeration removes excess and objectable gases. A packed tower
stripping system is used which removes 99.95% (or 179.91mg/L) of VOCs. This process also
reduces the pH of the water and has a retention time of 22.716 minutes (0.3786hr). Chemical
precipitation is performed on larger molecules which make up the suspended solids

Walkerton Water System Case Study
The Walkerton water system was supplied by three groundwater wells: wells 5, 6, and 7.
Contamination into the drinking water supply was through Well 5. Well 5 was a shallow well, and
all of the water drawn from the well came from a very shallow area. This water was drawn from an
area of highly fractured bedrock. This fracturing, and the geological nature of the surrounding
bedrock, made it possible for surface bacteria to quickly enter into the fractured rock (O'Connor,
2002, pp.166).
The water distribution system in Walkerton included 41.5 km of water mains as well as two
standpipes, which provided water storage and pressure equalization for the system. It is estimated
that in the Walkerton system, between 33 and 35 locations were "dead ends." There is a greater risk
of bacterial contamination in dead ends, because water does not adequately circulate in them and
may become stagnant (O'Connor, 2002, pp.57). The water system had a reserve capacity of 20
hours. ... Show more content on Helpwriting.net ...
One important purpose of the chlorine residual is to retain a capacity for disinfection in treated water
as it moves throughout the distribution system. Another is to provide a way to determine whether
contamination is overwhelming the disinfectant capacity of the chlorine that has been added to the
water (O'Connor, 2002, pp.14).
Well 5 was supplied by a groundwater source that was under the direct influence of surface water.
For such sources, the Ontario Drinking Water Objectives, required the continuous monitoring of
chlorine residuals and turbidity (The requirement for turbidity monitoring was to take four samples a
day or to install a continuous turbidity

A Modern State And Public Water Systems
A modern state is a set of organisations and institutions related to the function of the government; its
role is to provide order, policy, revenue, internal and external representation, and services.1 When
the state fails to govern the commons, that is, the land or resources affecting the whole community,
private companies take over. Within the past several decades privatization of the freshwater sources
and public water systems is widespread worldwide. Yet, private companies provide water guided by
the principle of the financial gain and not based on the equal distribution paradigm, and such
approach makes poverty–stricken suffer the most, while the wealthy remain intact. In California, the
region of the world having the seventh largest world 's economy,2 billionaires "hoard water in the
"water banks" that have been quietly gifted to them by the government."3 These water–bank–
systems allow to accumulate water in the underground reservoirs for water–bank holders ' needs or
for purpose of leasing.4 One such system, Kern Water Bank, a thirty square miles of marshland
filled with flocks of birds,5, is used to water pomegranate trees, a key ingredient in production of the
fruit–drink by POM–Wonderful, a company owned by the billionaires Stewart and Lynda Resnick.6
Ironically, Kern Water Bank Authority, technically a public agency, is subsidized by the Paramount
Farming Company, a company with world 's largest pistachio and almond production, which is also
owned by the Resnicks.

Role Of The Systems Approach For The Water
The Role of the Systems Approach for the Water – Food – Energy Nexus The role of the systems
approach when dealing with the water, food, and energy nexus is to understand and depict the
interconnections between all parts, to ensure the parts are divided equally, and that the sum of all
parts equals the whole. By focusing on just one part, for instance water – trying to make the heating
of water and the extraction of water better, you can actually be causing more issues at the expense of
the energy sector. According to the Food and Agriculture Organization of the United Nations, "This

responses, allowing for more integrated and ... Show more content on Helpwriting.net ...
One notable energy source is biofuel. Biofuel is made from agricultural efforts. While this seems
like a win/win for the energy industry, and the agricultural industry, it's detrimental to the water
industry. How? If you take a step back, you will see that the demand for fresh irrigation water is
increased, so is the increase for pesticides and fertilizers. With unsustainable irrigation practices,
water run–off, the lack of watershed management programs, and unpredictable climate changes and
weather patterns, surface and ground waters are more susceptible to pollution and contamination.
This is a reality that Lake Okeechobee knows all too well right now. Back pumping from sugar cane
agricultural land into Lake Okeechobee has caused surface water contamination, and a call for a
"state of emergency" for the lake and its water quality.
Water and Energy Nexus of Providing Hot Water Since water isn't naturally "hot", it takes energy to
get it to a desired heated temperature. There are different types of energy used to get water to a
heated temperature: solar energy, electrical power, hydro–electrical power, etc. Knowing the linkage
between what energy makes water heat up the fastest, yet is the cleanest would be the most desirable
choice for the water–energy nexus in providing hot water. Ideally, to collect and store solar energy
for water heating usage would solve two

Community Water System
The environmental justice hypothesis as stated by Brown, P. is that "hazards in the physical and
chemical environmental disproportionately affect those individuals and households that also face
hazards in their social environment. " What Brown is indicating is that environmental justice is
mostly seen being acted upon people belonging to the groups of poor, minority and color. The issue
of injustice of exposure of arsenic in poor, minority and color groups is a complex one because of
the natural occurrence of arsenic in ground water shows no bias in who it affects. It can only be
avoided through adequate testing and treatment. The injustice stems from the legal enforcement of
new regulation of the Safe Drinking Water Act (SWDA), updated on January 22, 2001, and the
differences in detection and treatment as subject to different racial and socioeconomic groups.
Regulated communities are asking for flexibility in design of enforcement because it is harder for
small public water systems (PWS) to adhere to new regulation. Smaller systems are unable to adhere
to new regulation in time because they do not have the finances to update technology and
machinery. Since they serve a smaller number of people the cost of updating their facilities is higher
per person. Larger systems are able to spread out the cost more efficiently among a larger number of
people making it easier for them to comply (Cory, D.C.).

Case Analysis Of The Clean Water System
Summary:
The petitioner, Los Angeles County Flood Control District (District), controls a municipal separate
store sewer system, also known as MS4, which was discharging polluted storm water into four
rivers (Los Angeles River, San Gabriel River, Santa Clara River and Malibu Creek) that exceeded
pollutant standards into navigable waters beginning 2002 or 2003. The MS4 is a system of
conveyances that is designed to collect polluted storm water and discharge the water into navigable
waters. It is not a combined sewer or a part of a sewage treatment plant. MS4 operates are required
by the Clean Water Act (CWA) to obtain a National Pollutant Discharge Elimination system
(NPDES) permit before discharging water. The respondents, Natural ... Show more content on

The data from the stations allowed the Ninth Court of Appeals to hold the District liable for the Los
Angeles and San Gabriel rivers.
On June 25, 2012, the Supreme Court granted review of the case only to answer the following
question: "Under the CWA, does a discharge of pollutants occur when polluted water flows from
one portion of a river that is navigable water of the United States, through a concrete channel or
other engineered improvement in the river, and then into a lower portion of the same river?". Using
the S. Fla. Water Mgmt. Dist. v. Miccosukee case, they answered with the following statement;
"pumping polluted water from one part of a water body into another part of the same body is not a
discharge of pollutants under the CWA. For the reasons stated above, the supreme court reversed
and remanded the case.
Analysis:
The main issue of the case was that the Los Angeles County Flood Control District allowed storm
water runoff that exceeded pollutant levels to discharge into rivers that flows into the ocean. The
case mainly focuses on defining the Clean Water Act,

Water Filtration Systems And Its Effect On The Environment
With the rising popularity of bottled water, which at that time was a billion dollar business, the sales
of Clorox's company Brita water filtration systems began to decrease. Instead of being defeated by
this, Clorox saw an opportunity to reposition its Brita brand as a "green" product to replace plastic
bottled water, which was causing landfills to become clogged. By using Brita water filtration
systems instead of bottled water, consumers would prevent millions of empty bottles each year from
being dumped into landfills and Clorox saw this as an opportunity to revive the fast dying Brita
brand. By conducting a successful marketing campaign, which promoted the green attributes of its
water filtration system, educating customer about bottle waste and its affects on the environment,
and encouraging them to switch to the Brita brand, sales of Brita water filtration system began to
rise. To get consumers excited about the product and involved in the bottle "saving" process, the
company created a website called FilterForGood which allowed consumers to pledge that they
would reduce waste by switching to Brita. It also totaled the amount of bottles saved so that
consumers could see how they were saving the environment and encourage them keep on using the
Brita water filtration system.
As Brita's filter cartridges also had to be replaced every few months, a recycling solution had to be
developed. To dispose of these filters, the company then formed a partnership with Preserve

Why Do Biological Systems Need Water?
Biological systems need water because it provides many functions. Water is a unique molecule that
is known to mankind and it is also important to the biological systems. Water exists in three states of
matter including solid, liquid, and gas. The solid phase of water is known as ice. Water is mainly a
liquid at room temperature. Water at room temperature supplies an environment for organisms to
live in as well as providing a liquid environment inside cells in order for them to live. The gaseous
phase of water is known as water vapor. Water is made up of 2 basic components called Oxygen and
Hydrogen. Water is known to be a polar covalent molecule and is the main indication of
transportation of substance between cells and tissues. Water acts as a solvent for chemical reactions
which helps transport dissolved compounds into and out of cells. Since water is ionized, it can be
used for many functions such as transportation in the body, nutrients, sugar, and salt can be
transported throughout the body through the bloodstream. Molecules such as glycogen are not
soluble and cannot be transported therefore will used for storage. Water can also act as a base and an
acid.

Many substances dissolve in water, and it is commonly referred to as the universal solvent. Animals
need a continuous supply of water for maximum efficiency. Because water functions as a lubricant
in the transport of feed and aids in the excretion of waste products from the body, the intake must
equal the output lost through urine, feces and evaporation otherwise known as sweat. Water also
plays a key part in digestion. Zaitseva, Danilov, Kalnin'sh, Lavrik, Fokin (2013), discovered that

Many American homes could benefit from water purification and filtration systems. Anderson Water
Systems explains that although municipal water systems have come a long way in terms of water
purification, there are still other possible sources that can cause unclean waters. Having been in
business for more than 60 years, they want you to be aware that old pipes can carry traces of lead
and that natural deposits and groundwater can contain various chemicals like arsenic, iron.
To combat these issues, Anderson Water Systems has crafted filtration systems that will purify the
water before you come in contact with it. By utilizing reverse osmosis, these systems can filter out
any contaminants and impurities. Whether we're drinking it from a tall glass or soaking in it in the
tub, water is such an integral aspect of our daily lives. Thanks to Anderson Water Systems, not only
will the water be cleaner and healthier, it will also taste much better.

Water Treatment Systems Should Be Banned
Many people in the United States, and in other parts of the world, take water for granted because all

world." (Adams 2003) What if clean, drinkable water was available to those people? Water is
needed to produce crops; it is also needed to hydrate people to keep them alive as well as feed
animals. Water treatment systems can be used to take contaminated water, like that which is found
all over the world in rivers and lakes, after it is run through a treatment system the water is lacking
contaminates and drinkable.

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

The Water Quality Of Freshwater Systems
Introduction The goal of this lab is to test the water quality of freshwater systems around the Roxana
area to determine if the local petroleum plant is causing a decrease in water purity. Literature review
To believe that human development has not increased our impact on the world we live in is a blind
mans assumption. In fact, scientists are able to detect even the incredibly small actions we have on
the world around us (National Geographic Freshwater 101: Pollution). New technology allows us to
see that our pollution is causing a great deal of damage, especially in aquatic ecosystems.
Freshwater ecosystems are often the receiving end of our pollution because they are abundant and
water will quickly wash our byproducts away. However, to say these byproducts do not affect other
locations is false. Often times, runoff of human sewage and waste will find its way to freshwater
ecosystems and harm the wildlife that resides there. Even humans can feel the affects of our own
waste. Pollution is just as likely to work its way into our drinking water as it is a nearby pond. And
in some parts of the world, there are no regulations to make sure that people are not consuming this
tainted water (National Geographic Freshwater 101: Pollution). There are many ways pollutants can
harm an ecosystem, but how they actually harm it is an unknown to many people. In a freshwater
ecosystem, the pH level of the water can greatly affect living organisms within the ecosystem. There

The Drought In California's Water System
Right now there is a drought in California and it is due to the water usage. Bach in the gold rush due
to miners mining for gold, the rivers became polluted and freshwater became limited. After the
earthquake in San Francisco that cause a big fire, San Francisco was in dire need of water so they
made a plan to built a dam in Hetch Hetchy. Many people argue as to whether to build the dam and
in the end the dam was built and that has shape California's water system hugely. The use of water in
California now has not been in the best interest of the state because The amount of water use for
agriculture is disportional, laws are making us use more water than needed and the Indians and
environment are being harm.

Indians for example are being poorer. In 1853 E.A. Stevenson states, "The Indians in this portions of
the State are wretchedly poor, having no horses, cattle or other property. They formerly survived on
game, fish,acorns, etc. but it is now impossible for them to make a living by hunting or fishing"(Doc
2). This is due to miners turning the stream to mines to look for gold and they can do that because of
the law of prior appropriations And after being use up, the stream become muddy causing fish to
seek for new houses which will also be destroyed due to more miners using the streams carelessly.
This causes Indians, animals and habitats to die. It is stated by Jerry Stanley in 1997, "The gold rush
meant death by starvation for thousands of Native Californians, and death from disease for
thousands more"(Doc 7). This shows the consequence made by the miners. They use the water for
their gold, polluting the rivers with mercury and to the Indians that drink the water they are die and
if they don't they will sooner ar later die of dehydrations. It also stated by Jerry Stanley that due the
tree being cut downs, animals left which were a food source for Indians. The Indians are not the
only one who were being harm. The environment is being harm. They cut down tree which are
habitats for animals and the animals have to leave home and find a new one buts people will
continue cutting trees and polluting water, and taking their home away again and the animals will
sooner or later die out This create a cycle that will end with animals becoming endangered or extinct
so we should start changing our water
