Water of Kho River between stretches of Kotdwar to Najibabad was studied for pollution load by determining various physicochemical parameters. The samples were collected from different Sites. The Site-I is Kho River at Kotdwar near Siddhbali Temple, Site -II is Kho river at Jahanabaad Dam near Najibabad, Site-III is Kho River at Lalwala Village near Najibabad. The river is subjected to carry the pollution of agriculture and domestic fields. The Physio-chemical parameters of river water such as pH, temperature, Alkalinity, Hardness, Turbidity, Dissolved oxygen, Biochemical Oxygen Demand, Chemical Oxygen Demand & Total dissolved solids. Most of the physico-chemical parameters were determined by standard methods prescribed by APHA. Each parameter was compared with the standard desirable limit prescribed by WHO. Comparison showed that river water was highly turbid (around 14.86 NTU) and rich in oxygen level (above 6mg/l) at all study sites. BOD and COD values were near the permissible limit, which shows the presence of microorganisms and organic matter. Thus the water of Kho River was unsuitable for drinking purpose but could be used for bathing, irrigation and domestic purpose.
