| Popis: | The water quality is one of the major criteria for the environmental evaluation based on the parametric changes in the physicochemical and biological properties of water. The distribution patterns of physicochemical and biological characteristics of the various rivers in the Imphal Valley have been studied in this work. The objective of the work is to determine the surface water quality of Imphal Valley to assess its suitability for domestic purposes. The physicochemical parameters of water such as water temperature, pH, hardness, alkalinity, EC, TDS, chloride, calcium, magnesium, sodium, potassium and nitrate were analysed for the experimentation. The biological characteristics were estimated from the Total coliform and Escherichia coli content of water. The physicochemical parameters were within the acceptable limits on the other hand Total coliform, and E. coli values were exceeding from the acceptable and permissible limits as prescribed by Bureau of Indian Standards (BIS). The study suggests untreated domestic disposal from market and household to the water body causes heavy pollution in rivers of Imphal Valley. |
