Abstract: Water pollution accidents occurred quite frequently in China, seriously threatening drinking water safety and water environment. Data and information of the 373 water pollution accidents that occurred during the five years from 2011 to 2015 collected and collated were for statistics and analysis of type of pollution, pollutants, measures taken to address the pollutions, scope of impacts and area of distribution. Results show that sudden pollution discharge, pollutant accumulation, pollution leakage, and piping accidents are the major sources of pollution risks and wastewater, chemicals, and oils are the main pollutants. Of the 373 accidents, 284 or 76.14% were addressed and 80 or 19.48% not. Most of the accidents occurred in the economically well-developed coastal areas in east and south China, like Shandong, Jiangsu, Fujian, Zhejiang and Guangdong, where the industry is highly developed and discharges large volumes of wastewater. The accidents have caused great concerns in the country. Besides, cases typical of sudden pollution discharge, pollutant accumulation, pollution leakage, and piping accidents were studied and analyzed for rationality of their addressing. On such a basis, more effective and rational pollution accident addressing programs were put forth for discussion.
