Since 1958, the World Health Organization(WHO) has published, at approximately ten-year intervals, several editions of international Standards for Drinking-Water and, subsequently, Guidelines for Drinking-Water Quality. In 1982, WHO shifted its philosophy from one of promoting "standards" to one of publishing "guidelines" so that individual countries could establish specific national standards and regulations appropriate to each ones own sociocultural,environmental and economic circumstances. 自1958年以来，世界卫生组织（世卫组织）已发表了大约10年时间，对饮用水和后来的几个版本的国际标准，指南的饮用水质量。 1982年，世卫组织已从促进“标准”一出版“指南”，使个别国家能够制定具体的国家标准和规章适合每个人的自身的社会文化，环境和经济情况之一的哲学。
