Abstract
[Objective]To comprehensively understand the development of drinking water quality standards in Shanghai and align with the requirements of standards such as Standards for Drinking Water Quality(GB 5749-2022),the Hygienic Specification for Facilities of Secondary Water Supply(draft for approral)(GB 17051),and Water Supply Quality Standards for Urban Water Supply(draft for approral)(CJ/T 206),and further strengthen the comprehensive management of water quality throughout the entire supply process-from the source to the tap-this initiative aims to ensure the safety of drinking water.[Methods]Present the full text of Shanghai Clean Tap Water Standards(1927)and Shanghai Tap Water Quality Standards(1950),introduce the indicates,implementation effectiveness,revision background,and principles of Standards for Drinking Water Quality(DB31/T 1091-2018),interpret the main content and rationale for setting specific water quality indicators and limits in the Drinking Water Quality Standards(DB31/T 1091-2025),and discuss challenges and countermeasures in formulating and revising drinking water quality standards.[Results]The 1927 Shanghai standard was China's first drinking water quality standard,the 1950 standard was the nation's first drinking water quality standard established after the founding of the People's Republic of China,and the 2018 standard was the country's first local drinking water quality standard following the establishment of China's standard system.Compared to the national Standards for Drinking Water Quality(GB 5749-2022),the Shanghai local standard,which will take effect on June 1,2025,introduces 5 new water quality indices,upgrades the limits for 38 indices,and significantly adjusts the reference indicates.This fully reflects the concept of standard leadership,Shanghai's unique characteristics,and the comprehensive protection of the entire water supply process.[Conclusion]The 2025 new local standards places greater emphasis on the impact of raw water quality,the effectiveness of treatment processes,changes in indicator risks,and alignment with relevant standards.In response to the challenges faced during the formulation and revision of drinking water quality standards-such as the diversity of pollutants,the complexity of limit value research,and technical-economic considerations-the strategy proposes to establish and dynamically update priority pollutant lists for drinking water.关键词
