1. INTRODUCTION

Water resources are sources of water that are useful or

potentially useful. Water resources are used in various ways including direct

consumption, agricultural irrigation, fisheries, hydropower, industrial production,

recreation, navigation, environmental protection, the disposal and treatment of

sewage, and industrial effluents. Water has sources and supplies, economic,

social, and political characteristics which

make it a unique and challenging natural

resource to manage.

97 percent of the water on the Earth is salt

water and only three percent is fresh water;

slightly over two thirds of this is frozen in

glaciers and polar ice caps. The remaining

unfrozen freshwater is found mainly as

groundwater, with only a small fraction

present above ground or in the air.

Fresh water is a renewable resource, yet the

world's supply of groundwater is steadily

decreasing, with depletion occurring most

prominently in Asia and North America,

although it is still unclear how much natural renewal balances this usage, and

whether ecosystems are threatened. The framework for allocating water

resources to water users (where such a framework exists) is known as water

rights.

2. What is water Resources?

Water resources are sources of water that are useful or potentially

useful. Uses of water include agricultural, industrial, household, recreational and

environmental activities. The majority of human uses require fresh water.

3. Sources of Fresh Water

Surface water

Surface water is water in a river, lake or fresh water wetland.

Surface water is naturally replenished by precipitation and naturally lost through

discharge to the oceans, evaporation, evapotranspiration and sub-surface

seepage.

Although the only natural input to any surface water system is precipitation

within its watershed, the total quantity of water in that system at any given time

is also dependent on many other factors. These factors include storage capacity in

lakes, wetlands and artificial reservoirs, the permeability of the soil beneath these

storage bodies, the runoff characteristics of the land in the watershed, the timing

of the precipitation and local evaporation rates. All of these factors also affect the

proportions of water loss.

Human activities can have a large and

sometimes devastating impact on these

factors. Humans often increase storage

capacity by constructing reservoirs and

decrease it by draining wetlands.

Humans often increase runoff

quantities and velocities by paving

areas and channelizing stream flow.

The total quantity of water available at any given time is an important

consideration. Some human water users have an intermittent need for water. For

example, many farms require large quantities of water in the spring, and no water

at all in the winter. To supply such a farm with water, a surface water system may

require a large storage capacity to collect water throughout the year and release

it in a short period of time. Other users have a continuous need for water, such as

a power plant that requires water for cooling. To supply such a power plant with

5

water, a surface water system only needs enough storage capacity to fill in when

average stream flow is below the power plant's need.

Nevertheless, over the long term the average rate of precipitation within a

watershed is the upper bound for average consumption of natural surface water

from that watershed.

Natural surface water can be augmented by importing surface water from

another watershed through a canal or pipeline. It can also be artificially

augmented from any of the other sources listed here, however in practice the

quantities are negligible. Humans can also cause surface water to be "lost" (i.e.

become unusable) through pollution.

Brazil is the country estimated to have the largest supply of fresh water in the

world, followed by Russia and Canada.

Under river flow

Throughout the course of a river, the total volume of water transported

downstream will often be a combination of the visible free water flow together

with a substantial contribution

flowing through sub-surface rocks

and gravels that underlie the river

and its floodplain called the hyporheic

zone. For many rivers in large valleys,

this unseen component of flow may

greatly exceed the visible flow. The

hyporheic zone often forms a

dynamic interface between surface

water and true ground-water receiving water from the ground water when

aquifers are fully charged and contributing water to ground-water when ground

waters are depleted. This is especially significant in karst areas where pot-holes

and underground rivers are common.

6

Ground water

Sub-surface water, or groundwater, is fresh water located in the pore space of soil

and rocks. It is also water that is flowing within aquifers below the water table.

Sometimes it is useful to make a distinction between sub-surface water that is

closely associated with surface water and deep sub-surface water in an aquifer

(sometimes called "fossil water").

Sub-surface water can be thought of in the same terms as surface water: inputs,

outputs and storage. The critical difference is that due to its slow rate of turnover,

sub-surface water storage is

generally much larger

compared to inputs than it is

for surface water. This

difference makes it easy for

humans to use sub-surface

water unsustainably for a long

time without severe

consequences. Nevertheless,

over the long term the

average rate of seepage above a sub-surface water source is the upper bound for

average consumption of water from that source.

The natural input to sub-surface water is seepage from surface water. The natural

outputs from sub-surface water are springs and seepage to the oceans.

If the surface water source is also subject to substantial evaporation, a sub-

surface water source may become saline. This situation can occur naturally under

endorheic bodies of water, or artificially under irrigated farmland. In coastal

areas, human use of a sub-surface water source may cause the direction of

seepage to ocean to reverse which can also cause soil salinization. Humans can

also cause sub-surface water to be "lost" (i.e. become unusable) through

pollution. Humans can increase the input to a sub-surface water source by

building reservoirs or detention ponds.

7

Frozen water

Several schemes have been proposed to make use of icebergs as a water source,

however to date this has only been done for novelty purposes. Glacier runoff is

considered to be surface water.

The Himalayas, which are often called "The Roof of the World", contain some of

the most extensive and

rough high altitude areas

on Earth as well as the

greatest area of glaciers

and permafrost outside of

the poles. Ten of Asia’s

largest rivers flow from

there, and more than a

billion people’s livelihoods

depend on them. To

complicate matters,

temperatures are rising more rapidly here than the global average. In Nepal the

temperature has risen by 0.6 degrees Celsius over the last decade, whereas

globally, the Earth has warmed approximately 0.7 degrees Celsius over the last

hundred years.

Desalination

Desalination is an artificial process by which saline water (generally sea water) is

converted to fresh water. The most common desalination processes are

distillation and reverse osmosis. Desalination is currently expensive compared to

most alternative sources of water, and only a very small fraction of total human

use is satisfied by desalination. It is only economically practical for high-valued

uses (such as household and industrial uses) in arid areas. The most extensive use

is in the Persian Gulf.

8

4. What is water pollution?

Water pollution is any chemical, physical or biological change in the quality of

water that has a harmful effect on

any living thing that drinks or uses or

lives (in) it. When humans drink

polluted water it often has serious

effects on their health. Water

pollution can also make water

unsuited for the desired use.

5. Various causes of water pollution

There are many types of water pollution because water comes from many

sources. Here are a few types of water pollution:

1. Nutrients Pollution

Some wastewater, fertilizers and sewage contain high levels of nutrients. If they

end up in water bodies, they encourage algae and weed growth in the water. This

will make the water undrinkable, and even clog filters. Too much algae will also

use up all the oxygen in the water, and other water organisms in the water will

die out of oxygen starvation.

2. Surface water pollution

Surface water includes natural water found on the earth's surface, like rivers,

lakes, lagoons and oceans. Hazardous substances coming into contact with this

surface water, dissolving or mixing physically with the water can be called surface

water pollution.

3. Oxygen Depleting

Water bodies have micro-organisms. These include aerobic and anaerobic

organisms. When to much biodegradable matter (things that easily decay) end up

9

in water, it encourages more microorganism growth, and they use up more

oxygen in the water. If oxygen is depleted, aerobic organisms die, and anaerobic

organism grow more to produce harmful toxins such as ammonia and sulfides.

4. Ground water

pollution

When humans apply

pesticides and chemicals

to soils, they are washed

deep into the ground by

rain water. This gets to

underground water,

causing pollution

underground.

This means when we dig

wells and bore holes to

get water from

underground, it needs to

be checked for ground

water pollution.

5. Microbiological

In many communities in the world, people drink untreated water (straight from a

river or stream). Sometimes there is natural pollution caused by micro-organisms

like viruses, bacteria and protozoa. This natural pollution can cause fishes and

other water life to die. They can also cause serious illness to humans who drink

from such waters.

6. Suspended Matter

Some pollutants (substances, particles and chemicals) do not easily dissolve in

water. This kind of material is called particulate matter. Some suspended

10

pollutants later settle under the water body. This can harm and even kill aquatic

life that live at the floor of water bodies.

7. Chemical Water Pollution

Many industries and farmers work with chemicals that end up in water. This is

common with Point-source Pollution. These include chemicals that are used to

control weeds, insects and pests. Metals and solvents from industries can pollute

water bodies. These are poisonous to many forms of aquatic life and may slow

their development, make them infertile and kill them.

8. Oil Spillage

Oil spills usually have only a localized effect on wildlife but can spread for miles.

The oil can cause the death to many fish and get stuck to the feathers of seabirds

causing them to lose their ability to fly.

6. Various effects of water pollution

Some people believe pollution is an inescapable result of human activity: they

argue that if we want to have factories, cities, ships, cars, oil, and coastal resorts,

some degree of

pollution is

almost certain

to result. In

other words,

pollution is a

necessary evil

that people

must put up

with if they

want to make

progress.

Fortunately, not

everyone agrees with this view. One reason people have woken up to the

11

problem of pollution is that it brings costs of its own that undermine any

economic benefits that come about by polluting.

Take oil spills, for example. They can happen if tankers are too poorly built to

survive accidents at sea. But the economic benefit of compromising on tanker

quality brings an economic cost when an oil spill occurs. The oil can wash up on

nearby beaches, devastate the ecosystem, and severely affect tourism. The main

problem is that the people who bear the cost of the spill (typically a small coastal

community) are not the people who caused the problem in the first place (the

people who operate the tanker). Yet, arguably, everyone who puts gasoline

(petrol) into their car—or uses almost any kind of petroleum-fueled transport—

contributes to the problem in some way. So oil spills are a problem for everyone,

not just people who live by the coast and tanker operates.

Sewage is another good example of how pollution can affect us all. Sewage

discharged into coastal waters can wash up on beaches and cause a health

hazard. People who bathe or surf in the water can fall ill if they swallow polluted

water—yet sewage can have other harmful effects too: it can poison shellfish

(such as cockles and mussels) that grow near the shore. People who eat poisoned

shellfish risk suffering from an acute—and sometimes fatal—illness called

paralytic shellfish poisoning. Shellfish is no longer caught along many shores

because it is simply too polluted with sewage or toxic chemical wastes that have

discharged from the land nearby.

Pollution matters because it harms the environment on which people depend.

The environment is not something distant and separate from our lives. It's not a

pretty shoreline hundreds of miles from our homes or a wilderness landscape that

we see only on TV. The environment is everything that surrounds us that gives us

life and health. Destroying the environment ultimately reduces the quality of our

own lives—and that, most selfishly, is why pollution should matter to all of us.

12

7. Different ways to stop water pollution

There is no easy way to solve water pollution; if there were, it wouldn't be so

much of a problem. Broadly speaking, there are three different things that can

help to tackle the problem—education, laws, and economics—and they work

together as a team.

Education

Making people aware of the problem is the first step to solving it. In the early

1990s, when surfers in Britain grew tired of catching illnesses from water polluted

with sewage, they formed a group called Surfers Against Sewage to force

governments and water companies to clean up their act. People who've grown

tired of walking the world's polluted beaches often band together to organize

community beach-cleaning sessions. Anglers who no longer catch so many fish

have campaigned for tougher penalties against factories that pour pollution into

our rivers. Greater public awareness can make a positive difference.

Laws

One of the biggest problems with water pollution is its transboundary nature.

Many rivers cross countries, while seas span whole continents. Pollution

discharged by factories in one country with poor environmental standards can

cause problems in neighboring nations, even when they have tougher laws and

higher standards. Environmental laws can make it tougher for people to pollute,

but to be really effective they have to operate across national and international

borders. This is why we have international laws governing the oceans, such as the

1982 UN Convention on the Law of the Sea (signed by over 120 nations), the 1972

13

London (Dumping) Convention, the 1978 MARPOL International Convention for

the Prevention of Pollution from Ships, and the 1998 OSPAR Convention for the

Protection of the Marine Environment of the North East Atlantic. The European

Union has water-protection laws (known as directives) that apply to all of its

member states. They include the 1976 Bathing Water Directive (updated 2006),

which seeks to ensure the quality of the waters that people use for recreation.

Most countries also have their own water pollution laws. In the United States, for

example, there is the 1972 Clean Water Act and the 1974 Safe Drinking Water

Act.

Economics

Most environmental experts agree that the best way to tackle pollution is through

something called the polluter pays principle. This means that whoever causes

pollution should have to pay to clean it up, one way or another. Polluter pays can

operate in all kinds of ways. It could mean that tanker owners should have to take

out insurance that covers the cost of oil spill cleanups, for example. It could also

mean that shoppers should have to pay for their plastic grocery bags, as is now

common in Ireland, to encourage recycling and minimize waste. Or it could mean

that factories that use rivers must have their water inlet pipes downstream of

their effluent outflow pipes, so if they cause pollution they themselves are the

first people to suffer. Ultimately, the polluter pays principle is designed to deter

people from polluting by making it less expensive for them to behave in an

environmentally responsible way.

8. Water conservation and the different ways

1. Check faucets and pipes for leaks

A small drip from a worn faucet washer can waste 20 gallons of water per day.

Larger leaks can waste hundreds of gallons.

14

2. Don't use the toilet as an ashtray or wastebasket

Every time you flush a cigarette butt, facial tissue or other small bit of trash, five

to seven gallons of water is wasted.

3. Insulate your water pipes.

It's easy and inexpensive to insulate your water pipes with pre-slit foam pipe

insulation. You'll get hot water faster plus avoid

wasting water while it heats up.

4. Take shorter showers.

One way to cut down on water use is to turn off the

shower after soaping up, then turn it back on to rinse.

A four-minute shower uses approximately 20 to 40

gallons of water.

5. Turn off the water after you wet your toothbrush.

There is no need to keep the water running

while brushing your teeth. Just wet your brush

and fill a glass for mouth rinsing.

6. Rinse your razor in the sink.

Fill the sink with a few inches of warm water.

This will rinse your razor just as well as running water, with far less waste of

water.

7. Check your toilets for leaks

Put a little food coloring in your toilet tank. If, without flushing, the color begins

to appear in the bowl within 30 minutes, you have a leak that should be repaired

immediately. Most replacement parts are inexpensive and easy to install.

15

8. Use your water meter to check for hidden water leaks

Read the house water meter

before and after a two-hour period

when no water is being used. If the

meter does not read exactly the

same, there is a leak.

9. Install water saving

showerheads or flow restrictors.

These can save a household 500 to

800 gallons per month.

10. Run only full loads in the

washing machine and dishwasher.

This can save 300 to 800 gallons

per month.

11. Shorten your showers.

Even a one or two minute reduction can save up to 700 gallons per month.

12. Turning off the water while you

wash your hands.

Turning off the water while you lather

uses 11.26 ounces of water on average.

By allowing the water to run while you

wash your hands you waste more than

three times the water than if you turn

off the water while you wash your

hands.

16

9. The various steps about Water pollution and water

conservation awareness

Understanding causes: If we don't understand why pollution happens, how can

we hope to stop it? We need to know whether pollution is point source or

nonpoint source—and what causes it

in each case.

Legislation: There are many different

anti-pollution laws and agreements

in operation in the United States,

Europe, and worldwide. Examples

include the US Clean Water Act, the

EU Bathing Water Directive, and the

MARPOL International Convention

for the Prevention of Pollution from

Ships.

Regulation: Sometimes pollution

seems unavoidable: from

papermaking to oil refining, many

industrial processes create pollution

as a byproduct. But instead of

accepting that as a fact, we can

regulate factories and allow them to

emit or discharge only limited

amounts of carefully controlled pollutants. By slowly reducing the levels of

permitted discharges, year by year and decade by decade, we can gradually bring

pollution under control.

Effective enforcement: Laws and regulations are worth nothing unless we're

prepared to enforce them—and punish offenders with fines or jail sentences. This

is part of an idea known as the polluter pays principle, which means people who

produce pollution should have to pay the costs they inflict on society.

17

Public awareness: The more people know about the causes and effects of

pollution, the more likely they're going to be to avoid adding to the problem.

Community action to tackle pollution, such as voluntary cleanups of rivers and

beaches, is very important.

Education: If we teach schoolchildren that pollution is a problem, perhaps we can

avoid turning them into future polluters?

Political pressure: If we want to create laws and regulations that effectively tackle

pollution, against the wishes of powerful companies, we're going to need ordinary

people to apply considerable pressure to their elected political representatives.

That's where campaigning groups and activists can play an important role.

Cooperation: It's easy to point fingers and blame "greedy corporations" for

polluting the planet, but we all have a share of the responsibility for pollution: if

you drive a car, travel by bus, or buy any goods that have been transported, you

use oil, directly or indirectly, and you're partly to blame for oil spillages in the

ocean.

Science: Understanding how pollution travels and persists in the environment can

play an important part in public awareness, education, and applying political

pressure. Good science can inform policy and legislation and empower

campaigners, but science alone rarely makes much difference.

Technology: There may be superb technological ways of cleaning-up pollution we

haven't yet discovered; similarly, there may be ways of avoiding pollution (for

example, by switching from gasoline-powered cars to electric ones to reduce our

dependence on oil).

11. Opinion, analysis, and experience

Three things no one can’t live without are Oxygen, Water and

Food. No one can live without Water. But do you know how precious is water and

how much pure water we have in world.

If 10 years ago someone had given

suggestion to sell the pure water, I’m

sure people made good joke or laughed

a lot on him. But nowadays mineral or

purified water is billion dollar industry.

People are ready to spend 20 rupees for

water bottle, because we know it’s not

easy to get pure or clean water.

One thing is sure; in future we are going

to get shortage of clean water. In India

you can see water shortage in every

state, whether it’s capital of India, Delhi

or a village of Kolkata. People can’t get

clean water easily.

Make "Water Conservation" compulsory

in all buildings, apartments. Privatize "Water Management" systems which will

bring in more efficiency. Spread awareness about the potential problems arising

due to water scarcity. I think this is more an awareness issue. There is attitude

which has to be eradicated. For this each one can take steps by spreading

awareness among friends, relatives and neighborhood.

Apart from the ideas mentioned initiatives need to be taken for Rainwater

harvesting at the village level. Ponds need to be created and they need to be

maintained. A lot of water is rendered useless because its polluted.

Lot of awareness needs to be spread at village level. A lot of awareness needs to

be spread in young students who are more receptive

21

Those who wish to protect environment of India they have to concentrate on

political pressure groups. Present laws, constitution, administration network,

awareness is quiet enough to protect our environment, animals, water sources

and pollution controls. People seating in ministries are not fool they know about

environment. Problems are in willingness and decision making. With Our whole

country reeling under a ubiquitous water crisis, we must spread awareness about

how this problem could

be contained. For that,

we ourselves have to

know how to deal with it.

People in India have no

care as to whether they

save water or not. Simple

steps like turning water

off while brushing or

shaving, cleaning of

porches and balconies

with buckets of water

rather than running

hoses, cleaning cars with

bucket water than

running hoses etc.

Each part of the chain worsens the water problem. No single way to stop this

exists. Everybody from individuals to companies to politicians should stricken up.

Otherwise we're looking at water wars real soon. This is not a one day problem;

this is not even one city or village problem. People in our country give damn for

this have any one constructed their house with few pot hole for rain water

harvesting or the villagers have removed the silt form their ponds without waiting

for the Government to come and help had they used drip irrigation and sprinklers

or the people in the city have have disposed their waste properly without

disposing them on roads and open spaces which is the major obstruction for the

22

water to get sunk into ground. If they have prevented the rapid decline of water

table by not exploiting it by bring well (especially commercial use).

Here are some water facts to remember:

Less than 1% of the earth’s water is suitable for drinking

More than a billion people around the globe survive on just over 1 gallon (4 liters)

of water per day

Potentially more than 3 billion people may suffer from water shortages by the

year 2025

66% of the human body

is water

A person can only live

without water for

approximately one week

Some of Facts about,

how valuable clean

Water is:

· More than 4 million people died due to water related diseases.

· 98% of water related diseases occurred in developing countries.

· It takes about 300 litres of water to make the paper for just one Sunday

newspaper. So use paper as less as you can, use E-mail and electronic sources

more.

· On average, women in Africa and Asia have to walk 3.7 miles to collect

water. It can be more in rural villages of India.

· In India alone, water born diseases cost the economy 73 million working

days per year.

23

· Global sales of bottled water account for over $60-$80 billion each year.

· A child dies of water born diseases about every 15 Seconds.

Aren‘t we aware of the different problems occurring in

our nature, especially in different bodies of water? Water pollution is the cause of

our undisciplined actions and irresponsibility. We, humans are only creating

problems that consequently we will also carry the burden of these problems. We

all know that water pollution can affect our health badly and seriously. It can

cause such sicknesses and diseases that

will badly affect our health. We all know

how important water is. Water is

essential to our body. Neither or every

living thing can‘t survive without water.

And so therefore, we should keep,

protect, save, and help prevent our

waters from being polluted ,we should

act as early as now, we should save

rivers, seas and oceans, and other bodies

of water because we will also bear the

burden of this problem. We should not

wait for the time until people are

competing just to get sufficient, fresh

and clean water, the time where clean

water is insufficient to the people and

animals, and the time where in our

sources of water are diminishing or until

the time where there are totally no sources of water. And so, let us be disciplined

and responsible enough to save, protect and conserve not only sources of water

but also our mother nature because our nature provides and helps us in our daily

lives. Let‘s just realize how important our mother nature is. It is our only source of

living. Let us not destroy it nor pollute it. Let us act for a change. We need and we

should help save and conserve our mother nature, especially the different bodies

of water. Absolutely, there are many simple ways in how we can help. Change

24

ourselves before we construct changes in our nature.

Life is ultimately about choices—and so is pollution. We can live with sewage-

strewn beaches, dead rivers, and fish that are too poisonous to eat. Or we can

work together to keep the environment clean so the plants, animals, and people

who depend on it remain healthy. We can take individual action to help reduce

water pollution, for example, by using environmentally friendly detergents, not

pouring oil down drains, reducing pesticides, and so on. We can take community

action too, by helping out on beach cleans or litter picks to keep our rivers and

seas that little bit cleaner. And we can take action as countries and continents to

pass laws that will make pollution harder and the world less polluted. Working

together, we can make pollution less of a problem—and the world a better place.

So please. Act right now!
