Production of healthy drinking water

One of the health problems of developing countries is the lack of safe drinking water. Since the axis of sustainable development is a healthy human being and human health depends on the benefit of drinking water, without the supply of healthy water, the health and well-being of society cannot be guaranteed. Water is important from both health and economic aspects. From the health point of view, it guarantees human health, and from the economic point of view, it drives the wheel of industry and the prosperity of the agricultural sector. According to the statistics of the United Nations Development Program in 2006, 1.1 billion people do not have access to drinking water and 2.6 billion people do not have access to sufficient water for sanitation, 700 million people in 43 countries face the problem of continuous water shortage and 1.8 Millions of children under the age of 5 die every day from diarrhea due to drinking unsafe water.

Water has many effects in the life of living beings, especially humans, in addition to providing the liquid needed by the body, it contains essential minerals and elements, the lack of which causes disorders in the body and disease. The lack of iodine and fluorine and their relationship with endemic goiter and tooth decay, respectively, express this importance. In addition to chemicals, some microscopic organisms in water cause dangerous infectious diseases. Water improvement has a direct relationship with the reduction of infectious diseases, so that after providing safe drinking water, the death rate from cholera is 1.74%, typhoid is 3.63%, dysentery is 1.23%, and diarrhea is 42%. It has decreased by 7.0%.

Below, you will get to know some concepts in the field of drinking water quality standards:

Drinking water: It is water whose physical, chemical, biological and radioactive characteristics are such that drinking it does not cause adverse effects to human health in the short or long term.

Optimal maximum: It is the maximum concentration of substances that is recognized as suitable for drinking water. If the water contains substances in a concentration higher than the maximum desired, it is at a lower level in terms of quality, but it is still drinkable.

Maximum allowed: If the concentration of substances in water exceeds the permissible limit, the water is not suitable for drinking and its continuous consumption in the long term will leave harmful effects on the health of the consumer.
