Abstract:
Objective To investigate if the finished drinking water quality index (FDWQI) can comprehensively reflect the actual situation of finished water quality in Shanghai.
Methods FDWQI was used to evaluate finished drinking water quality of 13 municipal waterworks in Shanghai.
Results The average annual FDWQI of the waterworks, of which the water source is the Yangtze River, was 20.19, and the "excellent" and "good" monthly evaluation results were half-and-half. The average annual FDWQI of which the water source is upper stream of the Huangpu River was 24.25, and the monthly evaluation results were mainly "good". FDWQI showed minor fluctuation in summer and major fluctuation in winter.
Conclusion FDWQI results are consistent with the water quality in Shanghai. However, the scientificity and objectivity of FDWQI need to be validated in the future application.
