Investigation and analysis of drinking water quality in rural areas of Liuzhou City in 2018-2020 / 公共卫生与预防医学

ABSTRACT

Objective To understand the hygienic status of rural drinking water quality in Liuzhou City from 2018 to 2020, and to provide basic data for the government to formulate relevant policies. Methods The monitoring data of rural drinking water from 2018 to 2020 in Liuzhou City was collected and statistically analyzed. Results A total of 1 877 rural drinking water samples were collected from 2018-2020. The total qualification rate of the monitored samples was 69.26% (1 300/1 877). By chi-square test, the qualification rate of the water samples in different years showed an upward trend (χ2=39.548，P=0.000). The qualification rate in dry season (63.59%) was significantly lower than that in flood season (75.11%)(χ2=29.240，P=0.000). The qualification rate of microbiological indicators (71.12%) was obviously lower than that of other indicators, and the difference was statistically significant (χ2=1.062，P=0.000). The qualification rate of finished water (69.44%) was slightly higher than that of tap water, but the difference was not statistically significant (χ2=0.037，P=0.848). Conclusion Microbial contamination is the main hygienic problem in rural drinking water quality in Liuzhou area, which should be paid attention to by relevant authorities.
