Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
The chemical formula for water is H2O which means it contains 2 Hydrogen and 1 Oxygen atom.
71% of the planet we live on is water. Even our living bodies are 60% water.
However, every water we find is not drinkable. Drinking water, like every other substance, contains small amounts of bacteria. Most of these bacteria are common ones and they are generally not harmful. Chlorine is usually added to drinking water to prevent bacterial growth while the water streams through pipelines. This is why drinking water also contains minimal amounts of chlorine.
Water mostly consists of minerals and other inorganic compounds, such as calcium. There are several problems that can endanger the quality of drinking water.
Someone can detect coliform bacteria in drinking water. Coliform bacteria are a group of microrganisms that are normally found in the intestinal tract of humans and other warm-blooded animals, and in surface water. When these organisms are detected in drinking water this suggests contamination from a subsurface source such as barnyard run-off. The presence of these bacteria indicates that disease-causing microrganisms, known as pathogens, may enter the drinking water supply in the same way if one does not take preventive action. Drinking water should be free from coliform.
Yeasts and viruses can also endanger the quality of drinking water. They are microbial contaminants that are usually found in surface water.
