Water Quality Evaluation and Countermeasures of Drinking Water Source in Guangyuan City
Analysis of the water quality and health risk assessment of centralized drinking water sources at the municipal,county-level,and rural levels in Guangyuan City in 2022 reveals that the overall water quality of centralized drinking water sources in Guangyuan City is good,and the content of heavy metal elements meets the water quality standards.However,some water sources did not meet the water quality standards,and the main pollution factors were total coliform count,permanganate index,and total phosphorus.In the health risk assessment of carcinogens,it was found that the health risk of arsenic in centralized drinking water sources at the city and county levels is level Ⅰ.Among rural drinking water sources with a population of ten thousand tons,10 water sources have a health risk level of level Iarsenic,and 24 water sources have a health risk level of level Ⅱ arsenic.From both water quality assessment and health risk assessment,the situation of rural drinking water sources is not as good as that of municipal and county-level drinking water sources.Analyze the reasons for the differences and provide corresponding countermeasures and suggestions.
