Objective To study the bacterial contamination of barreled mineral water upended on water dispenders from Baise college/middle school students'dormitories.The total bacterial number,the coliform bacterial number and thermotoletant coliform bacteria of collected mineral water were monitored. Methods A total of 231 drinking water samples from the dormitory water dispenders were randomly collected from 5 col-leges/middle school students'dormitories in Baise city and then the samples were plated on culture media and detected according to GB/17324-2003 and GB5749-2006 criteria. Results Among the 231 water samples, the average qualified rate of the total baterial reached 72.29%,the average qualified rate of coliform bateria was 82.25%;the thermotoletant coliform bacteria,91.34%.After the water samples during spring and summer were monitored,results revealed that the summer water samples achieved a higher qualification rate of 85.84%than those of the spring samples.The qualification rates of spring water samples in the first three days since starting use were 90.00%,88.37% and 85.71%,respectively,while on the 1st day from beginning use,the summer water sample reached a higher rate up to 100%. Conclusion The total plate count and the duration of drinking are the two crucial factors that influence the qualification rate of barreled drinking water from students'dormitories of college/middle school in Baise city.Awareness of water sanitation should be strength-ened so as to ensure the quality of the drinking water and the physical health of the students.
