Awareness of People on Safe

Water by Using a Short Film

Water is a fundamental human need. Each person on Earth requires at least 20 to 50 liters of
clean, safe water a day for drinking, cooking, and simply keeping themselves clean. That is why
–the other name of water is life.
Polluted water isn’t just dirty—it’s deadly. Some 1.8 million people die every year of diarrheal
diseases like cholera. Tens of millions of others are seriously sickened by a host of water-
related ailments—many of which are easily preventable.
Education suffers when sick children miss school. Economic opportunities are routinely lost to
the impacts of rampant illness and the time-consuming processes of acquiring water where it is
not readily available. Children and women bear the brunt of these burdens.
To aware people we can use a short film. This is very fruitful and a strong media that can
connect the mass people in an easy way and help them to change their behavior as well. The
can also learn how to make water safe.

Contribution of short film to use safe water:

a. This is a very popular and common media to the general people. The message of the film is
accepted to them. When the watch the movie the find themselves in that film. Thus the
messages enter their brain in a very easy way. The other thing is that they also enjoy the movie.
It has great impact in society as well. After watching the movie they deliver the ideas to their
neighbors. That is why we can follow this media to aware people on using safe water. A proverb
goes- Safe water saves life.

b. It is very easy to demonstrate a shot film. A simple instrument is required to show the movie.
In a small place many people can enjoy the film. So, we can deliver our message on importance
of using safe water without any threat.

c. Now days any people of any place can make short film on the basis of his/her requirement. If
a person has a high resolution mobile, he can be a film maker. Besides, a cameras phone he
should have a knowledge of video editing. Thus he can make film on water and hygiene and he
can aware the unconscious people who living in the darkness.
d. We can deliver the message of using clean water in the remote places like hill tracts or in an
island through this media. The people of that places can get this messages and can be aware can
keep themselves away from various diseases like cholera, diarrhea and other water born diseases.

e. This media has acceptance to the mass people. So, the messages of the short films must be
accepted by the mass people. Therefore, when we make a short film must keep in mind the
message that we like to deliver. We have to select the place and person relating with our
messages. In this short film our content is making aware people on using safe water. We must
select the rural area and the person the films should be the common laborious people of our state.

Some adverse (bad) effects of water pollution are as follows:

Water pollution adversely affects the health and life of man, animals and plants alike. Polluted

water is also harmful for agriculture as it adversely affects the crops and the soil fertility.

Pollution of sea water damages the oceanic life.

1. Health Aspects of Water Quality:

Consumption of polluted water is a major cause of ill health in India. Polluted water causes

some of the deadly diseases like cholera, dysentery, diarrhoea, tuberculosis, jaundice, etc.

About 80 per cent of stomach diseases in India are caused by polluted water.

2. Effect of Organic Pollution on Water Quality:

All organic materials can be broken down or decomposed by microbial and other biological

activity (biodegradation). Organic and some of the inorganic compounds exhibit a biochemical

oxygen demand (BOD) because oxygen is used in the degradation process.

Oxygen is a basic requirement of almost all aquatic life. Aquatic life is adversely affected if

sufficient oxygen is not available in the water. Typical sources of organic pollution are sewage

from domestic and animal sources, industrial wastes from food processing, paper mills,

tanneries, distilleries, sugar and other agro based industries.

3. Effect of Nutrients on Water Quality:

Water supports aquatic life because of the presence of nutrients in it. Here the primary focus is

on fertilizing chemicals such as nitrates and phosphates. Although these are important for plant

growth, too much of nutrients encourage the overabundance of plant life and can result in

environmental damage called ‘entrophication’.

This can occur at both microscopic level in the form of algae and macroscopic level in the form

of aquatic weeds. Nitrates and phosphates are contributed by sewage, agricultural run-off and

run-off from un-sewered residential areas.

4. Effect of High Dissolved Solids (TDS) in Water Quality:

Water is the best solvent and can dissolve a large variety of substances which come in its

contact. The amount of dissolved solid is a very important consideration in determining its

suitability for drinking, irrigation and industrial uses. In general, waters with total dissolved

solids of less than 500 mg/litre are most suitable for drinking purposes.
Higher amount of dissolved solids may lead to impairment of physiological processes in human

body. Dissolved solid is a very important criteria for irrigation. This is due to the fact dissolved

solid accumulates on the ground resulting in salinization of soil.

In this way it renders the agricultural land non-productive. Dissolved solids are harmful for

industries also because they form scales, cause foaming in boilers, accelerate corrosion and

interfere with the colour and taste of many finished products.

5. Effect of Toxic Pollutants on Water Quality:

Toxic pollutants mainly consist of heavy metals, pesticides and other individual xenobiotic

pollutants. The ability of a water body to support aquatic life, as well as its suitability for other

uses depends on many trace elements. Some metals e.g., Mn, Zn and Cu present in trace

quantity are important for life as they help and regulate many physiological functions of the

body. Some metals, however, cause severe toxicological effects on human health and the

aquatic ecosystem.

6. Effect of Thermal Discharges on Water Quality:

The discharge of cooling water from industrial and commercial operations generally heats up

the aquatic environment. Organisms may become physiologically stress or may even be killed

when exposed to heated water. If water heating is supplemented by the summer heat, the

impact on aquatic environment can be disastrous.

Thermal pollution also causes a decrease on the driving force or oxygenation which may

directly kill aquatic life through asphyxiation. If toxic pollutants are present in the aquatic

environment, thermal pollution may increase their toxicity to the aquatic life. Bioavailability of
many pollutants may also increase due to thermal pollution, which may ultimately adversely

affect the aquatic life.

Conclusion:
In our short film the above messages of using polluted water must be include so that the people
understand the need of safe and clean water. We are using film media to aware people on
using clean water. So, in our film we must include the importance of safe water and bad effect
of using polluted water as well.
