Abstract

A preliminary study on the physico-chemical parameters of Kongba River was carried out on the parameters like water temperature, total solids, total suspended solids, total dissolved solids, turbidity, conductivity, pH, free carbon dioxide, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, chloride, total hardness, calcium, magnesium, total alkalinity, sodium, potassium, sulphate and inorganic phosphate at seven selected sites. Site I,II,III and IV are river water, while site V, VI and VII are major drain water which joins and pollute the river system. Water Quality Index value of Kongba river ranges from 159.16 to 272.36. Site III has the highest WQI value of 272.36, while site II has the lowest value of 159.16. Major drains and various anthropogenic activities played an important role in deteriorating the water quality of Kongba river.
