ABSTRACT
The study examined the status of some physicochemical parameters in River Rido one of the tributaries of River Romi, Kaduna. Water samples were collected from January to October 2016 at four sampling points. A total of 40 samples were collected in dry and wet seasons. The physicochemical parameters were analyzed using standard methods. The results show that the Conductivity, Turbidity, Total Hardness, TSS, TDS, COD, and Oil and grease are above the permissible limit of NESREA and WHO guidelines indicating some level of pollution in the stream. Chemical Oxygen Demand (COD) with mean value ranging from 105.2mg/l -161.4mg/l and 72.4 mg/l -197.6 mg/l for dry and wet seasons respectively, these values are above the acceptable limit of WHO and NESREA guidelines for surface water of 15 mg/l and 40 mg/l respectively. Result of the t-test shows that there is no significant difference in the levels of concentration of the parameters between the dry and wet seasons. The result also shows that there is an adverse impact on the physiochemical characteristics of the receiving river as a result of the effluents discharge from Kaduna Petrochemical Refinery, sewage waste water, surface run-off and from agricultural chemicals. This may pose a health risk to the communities which rely on the receiving water bodies as their sources of domestic water and for agricultural uses. The study therefore, recommends that industrial waste water should be properly treated.
