Abstract : Levels of Physicochemical and Irrigation Properties of surface water from Okochiri creek in Rivers State, Nigeria were assessed in this study. Physicochemical properties were determined by using standard methods recommended by the American Society for Testing and Materials (ASTM) and American Public Health Association (APHA), water quality index was determined using an adopted mathematical model, and classification of water for irrigation purposes was made by plotting the Wilcox diagrams and other irrigation parameters such as Sodium Absorption Ratio, Soluble Sodium Percentage, Residual Sodium Bicarbonate, Permeability Index, Magnesium Adsorption Ratio and Kelly Ratio. The results show maximum mean levels of pH (7.3±0.1), pH levels were generally within set limits. The levels of chloride, hardness, total dissolved solids, conductivity, calcium, magnesium, sodium, dissolved oxygen and chemical oxygen demand (46.80 – 485.06 mg/l) exceeded their permissible limits. Water Quality Indices showed that the water in the area is generally unsuitable for drinking. Plots of the Wilcox diagrams indicate that the surface water in the area is unsuitable for irrigation. The results showed that the water is very poor for consumption and therefore should not be used for both drinking and irrigation purposes without proper treatment.
