Methods According to the standard test method of drinking water in GB / T 5750-2006, three kinds of water samples collected during the past three years in the dry and wet season respectively were collected for sensory traits, general chemical indicators, toxicological indicators, microbial indicators, disinfection Indicators 28 and 20 were measured. Results A total of 124 centralized water supply systems at county and townships, 76 decentralized water supply in rural areas and 162 centralized water supply in the “Eleventh Five-year” rural areas were monitored. The passing rates for comprehensive indicators were 29.0%, 19.7% and 21.6% respectively. Higher than the standard rate of bacteriological indicators and disinfection indicators, decentralized water supply by pollution. Conclusion There are hidden dangers in drinking water safety of residents in this county, poor water source protection and lack of effective disinfection measures.
