“WATER” What is water ?Meaning of water Based on dictionary,a transparent, odorless, tasteless liquid, a compound of hydrogen and oxygen, H 2 O, freezing at 32°F or 0°C and boiling at 212°F or 100°C, that in a more or less impure state constitutes rain, oceans, lakes, rivers, etc.: it contains 11.188 percent hydrogen and 88.812 percent oxygen, by weight.

Scientifically,Water is a basic molecule made up of two hydrogen atoms and one oxygen atom. When these three atoms come together, they form a strong bond that is difficult to break. The strength of this bond keeps a water molecule together for millions and even billons of years.

Bodies of water Brook

The smallest body of water is the brook. Natural stream of water that is found aboveground and is often called a creek as well.

RiverA river is a larger body of water that flows aboveground, in a particular direction, and usually has a large volume of water in it.

Problems quality Water quality is affected by both point and non-point sources of pollution.These include sewage discharge, discharge from industries, run-off from agricultural fields and urban run-off.

• Point source pollution results when the contaminants come from a single location. Examples of point source pollution in the air, water and soil.For example, Water. A company has a new tank. This tank is being treated with a special chemical. After the tank is treated, the treatment chemicals are drained into a stream that runs hear the building where the company is. The chemicals are released directly into the stream water without being treated or decontaminated to make them safe.

• Non-point-source pollution results when contaminants are introduced into the environment over a large, widespread area. For example, Water. Acid rain from the air can enter the water cycle. The result is that it enters the environment. The acid is harmful to fish and other creatures in fresh-water lakes and streams.

Water quality is also affected by floods and droughts and can also arise from lack of awareness and education among users.

The user need to be involved to maintain water quality and look at other aspects like hygiene,environmental sanitation, storage and disposal cause they are critical elements to maintain the quality of water resources.

Benefits• FOR HUMANS AND ANIMALS

It also helps in all major functions of the body like circulation, excretion, absorption, nerve conduction, respiration, reproduction etc.

• FOR PLANTS Plants can make up their own food material especially Starch a form of carbohydrate using water(from soil), Carbon-dioxide (from air) in the presence of sunlight.

• FOR OUR DAILY ACTIVITIES Water is also used for cooking, washing, bathing, and cleaning dirt around the house. Water is also used for industrial, agricultural, fire, recreation, transportation, and others.

Conclusion Water is so important to our life.Three-quarters of the human body consists of water. Water quality also determines our lives

How do we keep the water quality ?

• Minimize the use of chemical

• afforestation or reforestation maximize

• Use water as needed
