Ideally, the water we drink must be clear, taste, smell, and contains minerals. Proper water consumption must be free of harmful substances like heavy metals, nitrates, bacteria, viruses or infectious agents.
Water that comes from the bowels of the earth is in principle possible to use. But rising sea levels and causing contamination of groundwater is no longer included in the category of consumption. To meet the needs of water, now water it consumes each day are made from a river or lake that is processed in such a way that is free from harmful substances before it finally empties into the house.
The World Health Organization (WHO), there are several types of pollutants that can be carried out in water, namely:
- Mikroorganiseme, such as bacteria, parasites and viruses. Most bacteria and parasites can be killed by the chlorine contained in the process of purifying water. Unfortunately the virus is more resistant and difficult to be removed.
- Mineral poisons, such as aluminum, arsenic, asbestos, Florine, nitrates, or mercury, can be found in tap water. Usually relatively small, but pollution from industrial and mining can make a number of toxic minerals increases.
- Organic compounds, such as remains of animals, pesticides, oil, paint, or hair.
- Radioactive materials such as uranium or radiokatif gas in very small quantities can be found in pure water.
- The remains of the chemicals used to treat water in a clean river water.
- Microbial contamination of water and water carried on a random distribution.
Contaminated hazardous materials may be carriers of disease transmission, such as cholera, typhoid or hepatitis A. Therefore, do not forget to consume clean water and cooked until done.
