Abstract：OBJECTIVE To evaluate the water quality of public direct drinking water(DDW)and municipal water in a riverside pedestrian area of Pudong New District of Shanghai sourced.Through data collection and analysis,aim to provide scientific evidence for optimizing water treatment processes and DDW equipment.METHODS A total of 23 purified drinking water treatment devices along the riverside walkway were selected as study subjects.In June and July 2024,two rounds of sampling were conducted at 23 DDW points and their corresponding municipal water sources,yielding 115 samples(46 municipal water samples and 69 DDW samples).RESULTS Drinking water samples exhibited significantly lower levels of total bacterial count,turbidity,pH,total chlorine,aluminum,and trichloromethane compared to municipal water samples(Z=-2.595,-4.850,-3.304,-10.123,-1.982,-9.794;P＜0.05).Zinc content in drinking water samples was statistically higher than in municipal water samples(Z=-2.135,P＜0.05).Both municipal and drinking water samples showed positive correlations between aluminum content and pH levels(P＜0.05).All 46 municipal water samples passed quality testing(100.00%compliance rate,46/46),significantly higher than drinking water samples(97.1%compliance rate,67/69),though the difference was not statistically significant(P＞0.05).The main non-compliant indicators in drinking water samples were total bacterial count and zinc content.CONCLUSION Direct drinking water management units need to strengthen daily maintenance and management.For areas with less water consumption and remote areas,the water quality can be improved by strengthening the frequency of maintenance,flushing the pipe network and water intake regularly.
