摘要 进行了一项实地研究，以评估喜马拉雅中部城镇边界内饮用泉水的泉水的理化特性的变化。对12个泉水进行了三个季节(冬季、夏季和季风)的监测。结果表明，计划外污水排放对泉水水质的直接影响，反映在硝酸盐、氯化物、硫酸盐、硫化物和电导率的显著区域差异上。城镇内的人口密度在3110至14 137人/公里-2之间变化，与水质有直接关系。位于人口稠密地区的泉水中所有这些化合物的浓度都较高。在一些泉水中观察到的硝酸盐浓度高达60 ppm，使水不适合人类饮用。泉水水质在不同季节没有明显变化。
Abstract A field study was conducted to assess variations in physico-chemical characteristics of water of the springs located within the boundary of a Central Himalayan town where the springwater is used for drinking purposes. Monitoring of 12 springs was carried out for three seasons (winter, summer and monsoon). The results indicate direct influence of unplanned sewage disposal on the springwater quality as reflected by significant regional variations in the concentration of nitrates, chlorides, sulfates, sulfides and electrical conductivity. Population density varies within the town from 3110 to 14 137 persons/km–2 and has direct relationship with water quality. Springs located in the densely populated area had higher concentrations of all these compounds. Concentrations of nitrates up to 60 ppm were observed in some springs, making water unsuitable for human consumption. No significant changes were observed in springwater quality during different seasons.
