The Ministry of Environmental Protection announced on May 20 the three new emergency drinking water protection standards, and asked all levels of government in disaster areas to strictly implement technical standards to ensure drinking water safety for the people in disaster areas.
At present, rescue and clean-up work has entered a crucial phase. The Ministry of Environmental Protection has issued relevant standards to guide people in disaster areas and rescue personnel, according to the Ministry's strict and well-conceived emergency measures, to ensure safe drinking water, said Minister of Environmental Protection Zhou Shengxian.
Zhou Shengxian said that the three new emergency drinking water protection standards, according to the main influences on drinking water sources, determine the technical measures and management methods of eliminating and controlling key pollution factors. For example, if water source sites become contaminated, the water supply treatment process will be adjusted to use activated carbon adsorption, advanced oxidation, and other emergency treatment processes.
The standard requires that drinking water plants must strengthen water quality monitoring, especially for pathogenic bacteria; pay attention to the effects of coagulation precipitation and the sterilization process; can increase the coagulant; and maintain a chlorine dosage.
The standards also required an increase in the frequency of water quality monitoring in regions where groundwater is used as drinking water, and add an organic compound monitoring index. If possible, pumping groundwater should be reduced or halted from groundwater drinking water sources close to the earthquake ruins.
