(1) Although using chlorine to purify water in tap water production can kill harmful substances such as pathogenic microorganisms, adding chlorine itself will cause new chemical pollution. Chlorine can react with organic matter in water to form chloroform, which is a carcinogen. At the same time, chlorine also destroys nutrition and easily leads to heart disease.
(2) In the water supply network, long-distance pipeline transportation, old and rusty pipelines, unclean water tanks and reservoirs in urban high-rise buildings, or years of non-disinfection can all cause secondary pollution. Secondary pollution makes bacteria, viruses and algae multiply, and the original chlorine and chloride, rust, heavy metals and radioactive substances make the water turbid and smelly, endlessly.
So tap water is not standard drinking water. In the increasingly polluted environment, people must have strict standards for drinking water in their bodies. To restore the true nature of water, drinking mineral water is in line with human needs, and drinking mineral water is more beneficial to people's health than drinking boiled water. Because boiled water loses too much oxygen, drinking boiled water is not conducive to oxygen supply to the human body.
