| Drinking water should be of high standards that upon | | | | drinking water is usually set by the specific |
| consumption there would be no eminent risk of | | | | government of that area or by the international |
| harming one's health. The human body is estimated | | | | standards. |
| to contain 60% to 75% percent water and the | | | | Access to Water |
| brain, 85%, with most of the human body parts | | | | We can measure the access to drinking water |
| containing a lot of water. The human body requires | | | | through the number of masses who the ways and |
| drinking H2O for various functions such as the | | | | means of having safe and adequate amount of |
| regulation of body temperature and provision of a | | | | drinking water. Inability to finance and maintain the |
| means through which nutrients are transported to | | | | involved infrastructure has led to the poor |
| other organs of the body. | | | | accessibility to safe drinking water. |
| In most regions of the world, humans consume | | | | Improved H2O drinking sources have been but in |
| water that is contaminated with disease vectors. It | | | | place and they include: household water connection, |
| is not safe for consumption and may result in chronic | | | | boreholes conditions, public standpipe, protected |
| illnesses, hence the need to put up water distribution | | | | spring and rain water. In coming up with safe water |
| systems and also put into use purification | | | | sources there also has to be the access of good |
| technology. Water purification is basically the | | | | sanitation facilities such as the connection to public |
| elimination of contaminants from raw water. | | | | sewers and septic systems. |
| Purification can be carried out through either the | | | | Sources from which water can be found include: |
| physical process which can be through filtration or | | | | ground sources, precipitation (rain, snow), surface |
| sedimentation. Secondly it can be purified through the | | | | water etc. With advancement in technology, |
| biological processes like the activated sludge or the | | | | purification methods have also advanced for the |
| slow sand filters. Chemical processes of water | | | | better filtration machines ranging from products such |
| purification include flocculation and chlorination and | | | | as vending dispensers, vending units and reverse |
| finally we can apply electromagnetic radiation through | | | | osmosis vending machines. |
| the use of ultraviolet light. | | | | Lack of water is among the major problems in |
| Purification reduces concentration of parasites, | | | | developing countries. But thanks to the Water aid |
| bacteria, viruses, algae, suspended particles and other | | | | program, that has helped provide water has seen |
| matters that may have come into contact with the | | | | improvement of hygiene to the people living in areas |
| water as it falls into the rain. Basically, the quality of | | | | where by safe drinking H2O was a problem. |
