Abstract
This study was conducted in Kajola a town near Owu falls in Kwara State. It was aimed at assessing the quality of groundwater and its suitability for drinking and other domestic use. Groundwater from 2 boreholes and a reservoir (containing well-water) were sampled and analysed for the following physico-chemical water quality parameters using standardized procedures: (pH, dissolved oxygen, Electric conductivity, Turbidity, Total dissolved solids, Total solids, Chloride, Alkalinity, Magnesium, Sodium, Biochemical oxygen demand, Chemical oxygen demand, Total hardness, Nitrate, Total suspended solid, Sulphate) and Temperature which was measured in-situ. Results obtained from the laboratory shows that all parameters tested for except BOD and Temperature of all samples were within the permissible limit of World health organization for drinking water, Nigerian standard for drinking water quality and other agency’s guideline available for comparison. The temperature of samples 1, 2 and the reservoir having a mean value of 28.7OC was slightly higher than the desirable limit of 25OC indicating thermal pollution which can be corrected by installing Thermostatic mixing valves to ensure safe temperature. Also, the BOD concentration can be reduced by application of hydrogen peroxide hence making the water in Kajola safe for drinking and other domestic purpose.
