The present study aims to provide pollution status and the extent of disturbance made by the anthropogenic activities in the study area located in the Mizoram University. Different physico-chemical parameters of water, soil and Important Value Index (IVI) of vegetationwere analysed in this study. In the water quality analysis, the pH value 6.490.03in winter season at Site II is lesser than the permissible limit set by the World Health Organisation (WHO) and Bureau of Indian Standard (BIS-10500). The soils pH value which ranges from a maximum of 4.430.04 in rainy season at Site I and a minimum of 40.46 at Site III in winter seasonwere also slightly acidic which may due to high litter fall and its decomposition. In the vegetation analysis, 12 different tree species of 9 families were found and Schima wallichi got first rank with the highest IVI value followed by Phoebe lanceolata and Toona ciliata respectively. The overall analyses of different aspects with different parameters is barely done in this particular area which serves as one of the important source of fresh water and also its catchment areas provides a place for some wild animals.
