Abstract
Objective To understand the hygienic condition of drinking water quality in rural areas of Jiajiang county , Sichuan province and provide a scientific evidence for further strengthen sanitation management of drinking water in rural areas of this county. Methods The different types drinking water samples in the rural areas of this county were gathered respectively in low water period and high water period in 2014 and conducted supervision and inspection for water quality microorganism indexes according to GB/5749-2006 GB/T5750.1-13-2006 Drinking Water Health Standards and Drinking Water Standards Inspection Methods:bound volume. Results A total of 256 water samples were detected,in which,59.4%(76/128) of the water quality reaches the standard in the dry seasons,52.3%(67/128)in the abundant water seasons. There was no statisitcal significance in difference(P>0.05);The overall qualified rate of the total number of bacteria,coliform bacteria and heat-resistant coliforms in dif-ferent types of water resource were 51.6%(132/256),57.8%(148/256) and 59.0%(151/256) respectively,which had no statisit-cal significance in difference between the three(P>0.05). The qualified rate of coliform bacteria,heat-resistant coliforms in vari-ous periods were 51.6%(132/256),57.8%(148/256) and 59.0%(151/256) respectively,which had no statisitcal significance in difference between the three(P>0.05). The qualified rate of well water in different periods and various bacterial indexes was slightly higher than those of the source water and the table-water. Conclusion The qualification rate of the microbial indicators of drink-ing water for life in this rural area of this county is generally low. The major issues affecting the sanitary quality of water is micro-bial contamination,which instruct,that it should strengthen the health management,publicity and supervision of drinking water, and improve the disinfection of water processto ensure the rural residents′drinking water quality of this county safe.关键词
