Water quality is not only an environmental problem associated with people's life, but also a nation's political, economical and social problem. In order to investigate the quality of drinking water source, Wanjiazhai reservoir, the quality of water at cross section of Wanjiazhai reservoir is analyzed referring to current relevant water quality standards in China. As to those items exceeding relevant standards, their exceeding rate and maximum exceeding times are analyzed and calculated. Before and after draining from the reservoir, the main items exceeding the standards are determined, the quality of which varies with time and characteristic pollution are also analyzed. Their causation is analyzed and relevant solutions are suggested. All these are effective in being further polluted and protecting the cleanness of the drinking water source, which are beneficial in further improving the water quality and optimizing regulation of the water source so as to provide scientific criteria for ensuring people's health and friendly ecological system.
