Arun stream was evaluated for its physico-chemical properties and mineral composition to know its suitability for human comsumption. The results obtained from the physical characteristics like colour, odour, taste, turbidity, temperature, conductivity and total Dissolve solids were within the permissible limits of World Health Organization (WHO) for drinkable water.The results for the chemical analysis were total hardness (22.00±0.20mg/l), calcium hardness (16.00±0.10mg/l) magnesium hardness (22.00±0.10mg/l), Nitrate (0.32±0.10mg/l), Sulphate was absent, chloride (8.99±0.20mg/l), total Alkalinity (6.00±0.10) and PH (7.80±0.20) respectively.The mineral composition Analyzed were Iron (0.02mg/l), Manganese (0.015±0.01mg/l), Copper(0.01±0.01mg/l), calcium (6.4mg/l±0.10),Magnesium (1.46±0.10mg/l) and sodium (5.84±0.10mg/l) for Arun stream respectively. These values were below WHO specification for drinkable water.
