Objective To understand the health status and changes of rural drinking water in this county, to standardize the health monitoring of drinking water in rural areas in this county and to provide a scientific basis for the construction of rural drinking water safety projects. Methods According to the requirement of “Sanitary Monitoring Program for Drinking Water Safety in Shaanxi Province”, a statistical analysis was made on the monitoring results of rural drinking water quality in 2013-2015 in Mian County. Results The overall qualified rate of water quality in 2013-2015 was 50.91%. There was no significant difference between the qualified rate of water quality in wet season and dry season and the qualified rate of water samples at different monitoring points. Significant differences were found in the qualified rates of different water sources. Microbiological indicators exceeded the standard. Conclusion Mianxian rural drinking water safety project is not optimistic about the quality of water hygiene, mainly due to imperfect water treatment process and disinfection facilities.
