[0002] Water is the source of life. Human beings cannot live without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Since the formulation of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, level of scientific and technological development, water resources and their water quality status, there are differences in the requirements for drinking water quality not only between countries, but also between different regions in the same country.
