Analyzing the current statues of t urban drinking water source in China, we elaborated some ideas about risk assessment, risk assessment management, risk reduction and avoidance, the whole process of risk monitoring and information release and accident response for urban drinking water sources. Some advices were brought out as follows: 1) Risk assessment and management of urban drinking water sources should be carried out nationwidely. 2) Risk management for urban drinking water sources should cooperate with emergency management of basin environment. 3) The function of the governmental supervising and public service should be enhanced. 4) The mechanism of water source protection and corresponding compensation should be probed. For those cities with high risk of drinking water sources and having difficulty in eliminating or reducing the risk, change their water sources and choose lowrisk water sources for them if necessary.
