The discharge of untreated wastewater into the surface water bodies such as streams and<br>rivers results in the pollution of such water environments. We aimed to determine the physicochemical parameters and also<br>determine the seasonal variation of the physicochemical parameters river Kaduna.<br><strong>Methodology:</strong> The research was carried out within four areas in Kaduna North, Kaduna state, Nigeria. Selected sampling sites<br>include; Gamji Park, Kabala Costain, Malali and Unguwar Rimi. Monthly sampling of the four sites was carried out from each<br>sampling site for a period of eight months covering both the dry and the rainy season between 6:00 am and 8:00 am every sampling day. The following parameters were determined using standard laboratory techniques; temperature, pH, turbidity, total<br>dissolved solids, electrical conductivity, dissolved oxygen, biological oxygen demand, water hardness, nitrate-nitrogen and<br>phosphate-phosphorus. Data was analyzed using simple descriptive statistics to calculate the mean, standard error (SE) and<br>standard deviation of the parameters.<br><strong>Results:</strong> The mean water temperature was 23.6±0.90C with a standard deviation of 2.5, the highest temperature (25.7±0.60C)<br>was recorded in the wet season. Mean pH was 7.9±0.1 with a standard deviation of 0.4, the wet and the dry season had the same<br>mean values of 7.9±0.1. The mean turbidity was 60.3±4.6 with a standard deviation of 12.8, the wet season had the highest value<br>(72.5±2.4 NTU). Mean TDS was 72.1±13.9 with a standard deviation of 38.9 and the highest TDS value of 92.7±22.9 mg/L was recorded in the dry season. The mean values of electrical conductivity, dissolved oxygen and biological oxygen demand was<br>135±27.7µs/cm, 2.6±0.1mg/L and1.3±0.1mg/L respectively whereas water hardness, nitrate-nitrogen and phosphate-phosphorus<br>had means of 143.5±13.0 mg(CaCO3L-1, 0.3±0.0mg/L and 0.1±0.1mg/L respectively.<br><strong>Conclusion:</strong> physicochemical parameters were determined to be within the permissible level and wide seasonal variations were<br>seen among some parameters.</p> ER -
