Objective To understand the quality of rural drinking water in Fuling District and its existing problems, and provide a scientific basis for the construction of rural drinking water safety project in our district. Methods According to the method in GB / T 5750-2006 Standard Test Method for Domestic Drinking Water, samples were taken, stored and sent to laboratory for testing. Results A total of 140 monitoring samples throughout the year, 106 qualified, with a pass rate of 75.71%. The pass rate of toxicological indicators were 100.00%, some of the sensory indicators and general chemical indicators exceeded the standard in some extent, the microbial indicators exceeded the standard, the total number of colonies, Escherichia coli, total coliforms, heat-resistant coliform bacteria pass rate Respectively 90.00%, 90.71%, 83.57%, 85.00%. The results of wet season test pass rate (82.86%) higher than the dry season (68.57%) (P <0.05). The pass rate of water sample completely treated with water (91.00%) was significantly higher than that of precipitation and filtration (37.50%) (P <0.05). Conclusion Fuling District Rural Drinking Water Safety Project seriously exceeded the standard of water quality microorganisms. Relevant departments should strengthen supervision and management to improve the quality of drinking water health in rural areas.
