Abstract

Protection and the provision of safe drinking water has become the focus of world attention, many research results show that: the quality of drinking water is directly related to public health and safety, and sustainable economic and social development. Our drinking water safety problems caused due to pollution of water sources is also quite prominent, and how to protect the quality of drinking water sources has become a government concern, the focus of public concern. To this end, the water quality is the primary task of the scientific and rational evaluation of existing drinking water evaluation mainly focus on two aspects of water quantity and quality. As the environmental pollution problems have become increasingly prominent, new environmental problems are emerging, existing evaluation urgent rich. Many pollutants exist trace, trace the form of detection difficulty of detection technologies, testing requirements are also higher costs at the same time, awareness of the many dangerous chemicals and environmental pollution problems often require lengthy process, water quality standards update can not be avoided, there is a certain lack of lag. Therefore, the existing evaluation methods need to be improved. Evaluation methods for the establishment of drinking water sources from the point of view of the system of control of the process of drinking water sources, runoff catchment and water impoundment in the quality of water resources are increasingly scarce situation seems urgent and necessary. 'Green' water source assessment proposition, trying to build a \Relatively closed papers selected in the catchment area, a weak human activities reservoir water sources to start exploratory study to establish a \system, the major findings: 1. aspect combined with the ideas to build a system of \Vertical select a characterization of the status of the ecological environment evaluation and characterization of the evaluation of the risk of contamination of future trends; horizontal precipitation, catchment and water the whole process analysis, combing the risk of threat to the safety of the source water quality, and to analyze the impact of each of the risk of pollution sources and water sources ecological environmental factors to ensure a comprehensive and systematic assessment method index selection. Combining the results of survey of pollution sources in China, to establish the source of drinking water sources of pollution hazard rating list. Draw on the idea of ??the State of California, by the different sources of pollution hazard rating, Census Industry Classification combination of our country is now widely used sources of pollution, and to consider the characteristics of our sources of pollution, with reference to the countries' national list of hazardous waste and hazardous waste identification standard, to tease out the clear and practical source of contamination hazard rating list. Paper selected three reservoir-type water source, Zhejiang (hills and valley reservoir water source, river-type reservoir water source in hills and plains Valley reservoir water source application objects) as a case study to assess the period to 2008, conducted the \assess water. Combined with a change between the reservoir actual situation and the evaluation value of the three reservoirs can be seen, the evaluation method of the \The evaluation findings provide an important basis for the protection and management of water sources.
