3. Introduction to Drinking Water:
Drinking water refers to water that can be supplied directly for human consumption without treatment. Water is the main component of body fluids and is an essential substance for constituting cells, tissue fluids, plasma, etc. Water, as the medium for all chemical reactions in the body, serves as the platform for transporting various nutrients and substances.
On October 27, 2017, the International Agency for Research on Cancer of the World Health Organization released a preliminary list of carcinogens, and chlorinated drinking water was listed in Category 3.
Water is first divided into soft water and hard water based on its own hardness.
The hardness of water refers to the content of salt substances dissolved in water, that is, the content of calcium salts and magnesium salts. The unit of hardness is ppm, where 1 ppm represents a calcium carbonate content of 1 milligram per liter (mg/L). Water with a hardness below 142 is called soft water, while water with a hardness above 285 ppm is called hard water, and water with a hardness between 142~285 is called moderately hard water. Rainwater and snow water are both soft water, river water, lake water belong to moderately hard water; spring water, deep well water, seawater, are hard water.
Hard water usually does not directly harm health, but because hard water contains more calcium salts, kettles used to boil water are prone to scale formation. The precipitation of scale is mainly carbonate salts, as well as magnesium salts. These salts, when partially decomposed in the intestine, can become constant elements for some people; if they cannot be dissolved and decomposed, they will be excreted with the feces and will not have a special impact on the body. However, if scale exists, it will adsorb more harmful substances, thereby posing certain hazards. If a person has stone disease and it is calcium stone, drinking hard water excessively will aggravate the condition.
Drinking water includes clean natural spring water, well water, river water, and lake water, as well as processed mineral water, purified water, etc. Processed drinking water comes in forms such as bottled water, barrelled water, and pipeline direct drinking water.
