The Standards for Drinking Water Quality of China (2022 Edition) Will Take Effect.

Safe drinking water is a valuable public health resource that affects people’s livelihood and is essential for human health, making it an international concern for drinking water quality improvement. The Standards for Drinking Water Quality of China (China SDWQ) is a legal document approved and issued by the Standardization Administration of the People’s Republic of China that serves as a starting point for protecting public health and ensuring the quality of human life. There are three versions of China SDWQ, including the 1985 edition, 2006 edition, and 2022 edition. China SDWQ (2022 edition) sets a wide variety of indices covering biological, chemical, physical, and other risk factors in drinking water. Additionally, it establishes management requirements for the entire water supply process, providing a technical basis and criteria for ensuring drinking water safety and a scientific basis for developing drinking water safety policies and proposing targeted public health protection measures.
