Abstract
Through sorting out the current situation of environmental protection of urban centralized drinking water sources in Northwest China, and systematically analyzing the main problems and deficiencies in the process of standardization of centralized drinking water sources. Corresponding countermeasures are proposed from the aspects of system establishment and water source construction, source protection area division, water quality improvement, environmental supervision, etc., which provide references for the next step of water source management, environmental remediation and risk prevention and control.
Highlights
Drinking water safety is a necessary guarantee for social and economic development and residents ’stability, and the protection of drinking water sources is of great concern
Due to soil erosion, shrinkage of inland rivers and lakes, siltation of reservoirs, large water consumption for agricultural irrigation, and serious water pollution, the construction and protection of drinking water sources in the northwest region are difficult, and high-quality drinking water is even scarce in some areas with scarce groundwater resources [1]
In order to implement the "Water Pollution Prevention Law" and achieve the goals of residents' drinking water safety and environmental protection of water sources, the Ministry of Ecology and Environment organized a special action on environmental protection of drinking water sources, and comprehensively investigated the construction, operation
Summary
Drinking water safety is a necessary guarantee for social and economic development and residents ’stability, and the protection of drinking water sources is of great concern. In order to implement the "Water Pollution Prevention Law" and achieve the goals of residents' drinking water safety and environmental protection of water sources, the Ministry of Ecology and Environment organized a special action on environmental protection of drinking water sources, and comprehensively investigated the construction, operation,. Due to the regional natural environment, socio-economic level and water source distribution and other factors, under the new situation, there is still a certain gap between the environmental conditions of drinking water sources in the northwest region and the constantly strict requirements. It is necessary to sort out and analyze the standardized construction situation and existing problems of drinking water sources in the northwest region, and provide support for more reasonable water source protection, solving water source supervision problems, and ensuring drinking water health and safety in the future
