| Objective: Through the monitoring of drinking water quality in rural areas from 2008 to 2015 and in urban areas from 2013 to 2015 in Jilin Province,I aimed to analyze and summarize the qualified situation of drinking water for urban and rural residents in Jilin Province,and to provide scientific basis to improve the drinking water quality monitoring system for the relevant departments.In order to protect the residents' drinking water health safety,and to ensure healthy living and stability work for Jilin Province residents.Methods: The results of the monitoring of drinking water

microbiology indicators and the sensory traits and general chemical indicators.Main unqualified index of urban drinking water is the sensory traits and general chemical indicator.3.The qualified rate of overall water quality,microbiology indicators and toxicology index is higher than the plentiful water season except 2009.The qualified rate of the sensory traits and general chemical indicators is higher than the plentiful water season in 2011,that in 2008,2009,2013 is higher than the dry season.4.Percent of pass low project of rural drinking water is Total number of colonies,Total coliforms,Iron,Manganese.Percent of pass low project of urban drinking water is Turbidity,Total number of colonies,Total coliforms,Nitrate nitrogen,Iron. |
