Water is the source of life. No matter who we are, what we do, where we live, we depend on it to live. However, great as it is the importance of water, people continue polluting the rivers and its sources, forgetting how much it is essential to our lives. The majority of each of the cells in our body has water. We use the water for drinking, preparing meals for the personal and home care, or for fishing, transportation, electric power production, irrigation etc.
In nature, there are several types of water, depending on the elements it contains. Some are ideal for consumption, while others are harmful to health. They are:

1. Drinking water: the ideal type for consumption, is fresh and free of impurities;

2. Polluted water: it is dirty or contaminated water, i. e., it contains impurities, microbes, viruses, etc;

3. Fresh water: the water of rivers, lakes and sources;

4. Salt Water: is the one that contains many dissolved salts, for example seawater;

5. Distilled water :is composed of hydrogen and oxygen only, no impurities and any dissolved salt.
