Assessment of Water Quality Index of Nambol River, Manipur, India
Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 3
Abstract
Water Quality Index (WQI) Nambol River was analysed from July 2014 to January 2015 based on various physicochemical parameters obtained during this period. Nambol river flows through the small town of Nambol in Bishnupur district, Manipur and drains into the Loktak Lake which is included in Ramsar site. The water quality of this river has been severely affected while passing through Nambol town due to various anthropogenic activities. The physico-chemical parameter of water such as water temperature, free Carbondioxide, Dissolved Oxygen, Alkalinity, pH, Turbidity, BOD, Ammonia, Phosphate, and some metal elements were analysed. Water samples were collected from four sampling sites. The WQI value for these samples ranges from 67.878-85.276. The highest WQI value of 85.276 was recorded from Site IV which shows very poor water quality. The analysis indicates that the water is nearly polluted and not suitable for human consumption. Thus, river needs treatment so as to conserve this water body from future contamination and pollution. These findings have been discussed in the light of recent published literature.
