Abstract
Objective To assess the drinking water quality in Hexi, and Palang village, Yuanmou county after the drinking water improvement project. Methods We collected peripheral water from the End of the village, the Middle of the village, and the start of the village, as the same as the source water, and there were 12 water samples, 8 of which were from Hexi, another 4 were from Palang. We tested 14 parameters including organoleptic and physical parameters, microbiological parameters, toxicological parameters, and general chemical parameters. Results (1) After the 2010 water improvement project, manganese, fluoride, total number of colonies and turbidity were still exceeding the GB/T5750- 2006 " Standard examination methods for drinking water" . (2) The parameters including PH value chloride, oxygen demand, tatal hardness, sulfate, total dissolved solids, floride had statistically significant difference with the GB/T5750- 2006 " Standard examination methods for drinking water" (P＜0.01) , they were all declined after water improvement project; (3) Principal component analysis showed that chemical parameters played an important role in the drinking water quality, comprehensive score of Hexi was lower than Palang village.
