Objective To understand the quality of rural drinking water in Shangri-La County, analyze its influencing factors and provide a scientific basis for strengthening the supervision and management of rural drinking water safety. Methods The data of rural drinking water testing in Shangri-La County from 2009 to 2013 were analyzed. Results From 2009 to 2013, a total of 1244 water samples were tested, passing 280 samples with a pass rate of 22.51%. The passing rate of water quality was 18.21%, 19.64%, 27.14%, 29.64% and 8.75% respectively from 2009 to 2013 (P <0.01). The passing rate of factory water in dry season was 37.30% and the passing rate of factory water in wet season was 8.68% (P <0.01). The dry water at the end of dry season was 36.33% and the end of wet season was 7.72%, the difference was statistically significant (P <0.01). Sensory and general chemical indicators, toxicology indicators pass rate of 91.80% or more (with the naked eye visible, the pass rate was only 40.27%); the total number of colonies, total coliform bacteria, heat-resistant coliform bacteria pass rates were 47.91% 40.11%, 50.48%. Conclusion The quality of drinking water in Shangri-La County was poor from 2009 to 2013.
