Abstract: Physico-chemical parameters of River Katsina-ala at Buruku were investigated to assess the level of water pollution of the river which is a major tributary of River Benue in Nigeria. Monthly sampling from all the sampling stations was done for a period of 12 months (January to December 2016) between 7:00 and 11:00am. The water quality parameters studied include dissolved oxygen, water temperature, pH, alkalinity, total dissolved solids, Carbon dioxide, chloride, hardness, NH₃–Nitrogen, N-Nitrogen, biological oxygen demand, transparency and water depth. Standard methods were used to analyze the water samples collected. There was no significant difference in the mean location variation of all measured water parameters except dissolve oxygen (6.82±0.22, 6.01±24, 6.38±0.28 for stations A, B and C) hardness (25.17±1.93, 31.38±1.52, 28.08±1.36 for stations A, B and C) Biological oxygen demand (1.88±0.13, 2.57±1.13, 2.28±0.17for stations A, B and C) and Water Depth (0.94±0.04, 1.03±0.05, 0.91±0.03 for stations A, B and C). All the parameters measured were within the acceptable limit for drinking water and fish culture except Ammonia nitrogen (2.07±1.18) which was slightly above the safe standard by WHO and NIS indicating a slight pollution of the water body.
