Objective To analyze the microbial detection results of drinking water in a certain area.Methods 77 water samples submitted for inspection in 2022(including 60 for agricultural drinking water and 17 for urban drinking water)and 88 water samples submitted for inspection in 2023(including 74 for agricultural drinking water and 14 for urban drinking water)were studied.The total number of bacterial colonies,total coliforms and thermostable coliforms were detected according to the Standard Inspection Method for Drinking water.Compare the relevant differences.Results(1)The qualified rate of microbial indexes in 2022 and 2023 was 73.94%;In 2022,77 water samples were collected,and the total number of bacteria,total coliform,heat-resistant coliform and three comprehensive passrates were 62.34%,58.44%,58.44%,58.44%,respectively.The total number of bacteria,total coliform,thermostable coliform and the comprehensive pass rates of 88 water samples in 2023 were 87.50%,87.50%,88.63%and 87.50%,respectively.The total qualified rate of agricultural drinking water in 2022 and 2023 is 56.67%and 60.81%.The total qualified rate of urban drinking water in 2022 and 2023 is 94.12%and 92.86%;In 2022 and 2023,the total number of bacteria,total coliform,heat-resistant coliform and three total pass rates of agricultural drinking water and urban drinking water were compared,and the difference was statistically significant(P<0.05).Conclusion According to the results of sampling inspection,the qualified rate of urban drinking water is still not 100%,the qualified rateof rural drinking water is lower than that of urban drinking water,there are serious water pollution problems,relevant departments should strengthen the supervision of water quality in the future,and actively improve the disinfection work.
