Objective To understand the status of drinking water quality in rural areas of Ansai county and provide scientific basis for the relevant departments to select water,source and monitor plan. Method According to GB/T5750 - 2006, Standard Examination Method for Drinking Water, 240 rural drinking water samples from this county were collected and detected. Results 185 samples were qualified with the total pass rate of 77.08%. The qualified rate of microbiological and toxicological indexes were 90.41% and 92.5%, respectively. The qualified rate of groundwater quality was higher than that of surface water. The qualified rate of water colony was 78.75%, 78.75%, 78.75% and 72.50%, respectively. The total number of bacteria, heat resistant coliform bacteria, the visibility of the naked eye and turbidity were the main reasons for the low qualified rate of water samples. Conclusion In rural areas of this county, the management of drinking water sources is poor and lack of disin- fection measures, Therefore, it is necessary to strengthen the improvement and supervision and inspection as soon as possible to improve the quality of drinking water.
