Abstract

Abstract

To apply an improved integrated index method to evaluate the quality of three types of drinking water, the selected 26 indicators were classified into five categories according to various hygienic significances. And an appropriate weight was given to each category. Nemerow, minimum operator and five-color classification method were combined to evaluate the overall quality of the three types of drinking water from April to August in 2017. Except tap water in July and August, the quality index was at Level 2 (>0.5, blue), while other water all reached Level 1 (green). The organic pollution indicator was the most important impact of integrated index in different types of drinking water. Furthermore, the quality of two different water purifiers were better than the tap water, but some indicators require special attention.
- improved integrated index,
- water quality assessment,
- five-color classification method,
- tap water
