Tests were conducted under the directions of “Standard Test Method for Drinking Water” GB/T 5750- 2006, and the creterion of results was according to “Drinking Water Health Standards” GB5749- 2006. The results showed that in the investigated 28 farms, 17(60.71%) of which did not have regular sterilization and 24 farms (85.71%) did not have bacterial tests recently. There were only 3 chicken farms (10.71%) met the standard. As water flows through the waterline, the amount of bacteria becomes larger and larger. The qualification rate of E. coli bacteria in water samples was 50%, while the qualification rates of thermotolerant coliforms and Escherichia coli were both 82.14%.
