Abstract
In Sikkim, especially in the rural areas where there is no supply of treated water for drinking and other domestic uses,
natural surface water is the only source. The objective was to assess the water quality of natural sources of water in
the rural areas of East Sikkim using a water quality index (WQI) for different seasons. A total of 225 samples, that is,
75 in winter, 75 in summer, and 75 in monsoon were collected from different sources for physicochemical analysis,
and a WQI was calculated. The water quality values ranged 32.01-96.71. The results showed that most of the water
samples were in poor condition (85.3%) and very few of them were in good condition (2.6%). The water quality of the
natural sources indicated that the water is poor-quality and not totally safe for human consumption, and that it needs
treatment before consumption.
