Abstract:
Objective To find out about the sanitary conditions of drinking water along the border line of Inner Mongolia via safety evaluation of drinking water along the border line of Inner Mongolia.Methods 108 samples of drinking water along the border line of Inner Mongolia(70 samples of self-supply source water,21 ones of self-supply tap water and 17 ones of municipal tap water)were collected.Hygienic evaluation of sensory indexes, normal chemical indexes, toxicological indexes and microbiology indexes of water quality was performed according to hygienic standards for drinking water(GB 5749—2006).Results 58 samples were qualified with a total qualified rate of 53.7%.The unqualified rate of the total number of coliforms was the highest(20.4%),followed by fluoride(19.4%).As for deep wells, shallow wells and surface water,there was no statistically significant difference.Compared with municipal tap water,the unqualified rate of self-supply water(28.6%)was higher(17.7%).Conclusion The qualified rate along the border line of Inner Mongolia of drinking water is low.Treatment and disinfection facilities for drinking water,detection devices of water quality are needed.The cleaning and disinfection of storage tanks should be performed periodically in oder to prevent waterborne infectious diseases.
