Physicochemical parameters of kafin-chiri were investigated for three seasons. Concentration of metals and physiochemical parameters were determined from water, soil and plant from four sampling locations. Water, soil and plant samples were collected from each reservoir in four sampling locations during Rainy, Dry and Cold season. The result of the parameters; such as Dissolved Solid, Biochemical Oxygen Demand, Total Dissolved Oxygen, Suspended Solid, Total Solid, Temperature, Turbidity, colour Total Hardness, pH of water, pH of Soil, Conductivity of Soil, Conductivity of Water, Nitrite, Nitrate, Chloride and Phosphate ; Mg/L 1.40-4.0, 2.0-3.3, 27.9-50.0, 30.0-44.5, 2.140-164, 48.0-190, 30-34, 125-142 NTU, 200-350 Hazen, 35.4-115, 7-8.8, 4.28-6.16, 522-772,60-90.6, 0.012-0.02, 8.4-24.5, 18.54-28.5 and 1.1-3.0. The result shows a spatial and temporal variation p>0.05in all the sampling location. The value of pH in Water is 7-8.8Mg/L for Soil 4.28-6.16 Mg/L and Conductivity of Water 60-90.6µscm-1, for soil is 552-772µscm-1 it shows that soil has lower pH value and higher conductivity than water. The values obtained for all the parameters were found to be comparable to those reported by other researchers in similar environment. The result of metals analysis in water mg/L (Cr, Cu, Pb, Zn, Co, Cd, Fe, Mn and Ni) 0-0.73, 0-0, 0.058-0.07, 0.11-0.34, 0.045-0.197, 0.1-4.2, 0.02-0.06, 0.28-0.7 and 1.2-4.2 that of metal analyzed in Plant mg/kg, okra (Cr, Cu, Pb, Zn, Co, Cd, Fe, Mn and Ni) 0.78-0.94, 0.38-0.64, 3.1-4.24, 0.69-1.13, 0.65-1.1, 2.21-3.26, 2.12-2.67, 1.26-1.78 and 2.47-3.01; Spinach mg/kg, 0.52-0.68, 0.41-0.6, 0.48-0.69, 1.29-2.02, 0.63-0.91, 5.17-6.63, 4.98-6.01, 4.67-6.87 and 6.23-7.2; maize mg/kg, 0.04-0.1, 0.12-0.21, 0.23-0.48, 0.01-0.04, 0.06-0.418, 0.047-0.09, 0.01-0.23, 0.1-0.10 and 0.2-0.33 and level heavy metals in soil mg/kg (Cr, Cu, Pb, Zn, Co, Cd, Fe, Mn and Ni) 0.02-21, 0.2-0.35, 0.1-0.2, 0.019-0.02, 0.3-0.9, 0.4-1.2, 0.019-0.02, 0.57-1.0 and 8.4-14. Most of the elements analyzed were within the acceptable limit set by WHO. Some of the heavy metals in water, soil and plant are higher than the recommended values indicting the extent of pollution in the study location.
