Ojo %P 01-06 %X The effect of seasonal variation on the physicochemical properties of Ala river in Ondo state Nigeria was studied in this research. Thirteen water parameters including Total Hardness (TH), Turbidity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Conductivity, pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Chlorine (Cl), Mangnesium (Mg), Iron (Fe), Zinc (Zn) and Manganese (Mn) were analyzed on the three samples (Ala-Elefosan, Araromi and Oba-Ile) that were considered. From the comparison made between the obtained results and the Nigeria Standard for Drinking Water Quality (NSDWQ) permissible limit, it can be inferred that there were variations in the water quality from dry to wet season for all the parameters and recommended that adequate water treatment should be carried out before usage irrespective of the season. %K Seasonal Variation, NSDWQ, Physicochemical, Samples. %D 2022 %I Scienceline Publication, Ltd %T Seasonal Variation of Physiochemical Properties of River Water Samples in Akure, South-Western Nigeria %J Journal of Civil Engineering and Urbanism %N 1
