摘　　要：生活饮用水质量的优劣直接关系到居民的健康水平和生活质量,公众对生活饮用水的安全性及品质日益关注。饮用水的感官性状作为公众判定水质安全性的最直观指标,直接影响人们的使用意愿。以北方某城市生活饮用水为例,应用感官指数和健康指数评价其水质。结果表明,该市供水水质能够达到安全饮用标准,但感官品质和健康水平有待提升。适当的硬度和较低的硫酸盐含量是健康、美味饮用水的有益特征。Directly related to health and living conditions,the public attentions on drinking water quality and safety have been constantly increasing.As an intuitive characterization of the supplied water, the levels of sensory parameters are directly correlated to consumers impression and.acceptability of drinking water.In a case study in a city in north China,sensory and health indices were applied to evaluate drinking water quality.The results showed that the sensory level and the health-based quality indices needed to be further improved although it had met the current standards.In addition,suitable hardness and lower sulfate were beneficial characteristics of healthy and tasty drinking water.
