Drinking water resources have an irreplaceable effect on social and economic development and social stability. Once problems occur in drinking water sources, the consequences will be catastrophic. In recent years, drinking water sources in our country have frequent environmental pollution accidents. Compared with the conventional pollution, these unexpected pollution events have the characteristics of being uncertain, endangering the urgency and requiring quick response. In terms of types of accidents, the drinking water source of river-type drinking water is more likely to suffer the impact of upstream water and the probability of encountering unexpected environmental pollution incidents is greatly increased. Wuhan City, “the intersection of the two rivers” unique geographical location determines the city’s main source of drinking water are from the Yangtze River or the Han River, Wuhan is located in the middle reaches of the Yangtze River and the Han River
