Water quality testing

Water is the source of life and an indispensable resource for humans. It is used in human life and production activities, and the quality of water quality directly affects human health.

. Water quality pollution has also become a major factor causing human diseases, so water quality testing has also shown great necessity. 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 continue to increase, and drinking water quality standards are also continuously developed and improved accordingly. Due to the fact that the formulation of drinking water quality standards is related to various factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources, and water quality status, there are differences in the requirements for drinking water quality not only among countries but also among different regions of the same country
