According to the World Health Organisation, the quality of drinking water available to a person is a major determinant of his/her health. This is why it is important to pay attention to the quality of water available at home or in the office. The drinking water should be clear, colourless, and have no unpleasant odour or taste.

1. According to the World Health Organisation, the quality of drinking water available to a person is a major determinant of his/her health. This is why it is important to pay attention to the quality of water available at home or in the office. The drinking water should be clear, colourless, and have no unpleasant odour or taste.
Drinking water can either be bottled or come from the tap, and may contain small amounts of contaminants. The presence of contaminants in the water does not mean that it is not safe for drinking. Some contaminants are essential to the body and can give water a distinctive flavour.
Here is a quick guide to the most common types of drinking water:

2. Tap Water
This kind of water is drawn from the ground and surface water and varies in every location. Tap water can be processed, purified, or even treated with chlorine or filtered through activated carbon. This water, however, can never be turned into mineral water.
Purified
This water has been treated to remove pathogens and chemicals. Purified water is essentially free of all chemicals and may be free of microbes. This is usually cleansed and purified through processes such as reverse osmosis, deionisation, or distillation. It has a higher purity than spring water, filtered water, or tap water.

3. Natural Mineral Water
Mineral water must come from a subterranean source that is protected from potential contamination. Before it can be recognised as mineral water, it must be demonstrated by authorities through microbiological testing.
This kind of water is also subjected to ongoing testing and maintenance after its original qualifications.
Distilled Water
This kind of water is treated by condensation or boiling to remove solid components, inorganics, and a few organic chemicals. The distillation process kills microbes and removes minerals from the water, giving it a flat taste.

4. Filtered Water
The filtered water a person drinks is usually tap water that has been filtered to remove chlorine residue to improve the taste. Many filtered water systems are available and can be installed at home. There are also whole-house filtrations systems that provide clean water for the whole family.
The body depends on water for survival, so it is important to haveaccess toa clean supply at all times. Homeowners can have a supply of fresh and safe water by purchasing a home filtration system that removes bacteria in the drinking water.
