【 摘 要 】

This study was conducted to assess the impacts of industrial activities on the ground water quality in industrial and non- industrial area in Ilorin Town. The quality assessment was focused on physico-chemical parameters. Groundwater samples were collected from industrial area and from non-industrial area which were used as control. The results obtained were compared with standards prescribed by WHO. Total of 5 parameters were investigated. It was found out that all the sites had pH values between the permissible limit of 6.5 to 8.5 indicating that they are fit for domestic purpose. Sites 1 and 3 recorded highest conductivity of 285 to 320 µScm-1which was above the acceptable limit, this could be as a result of industrial activities taking place in the area, that is, influence of dissolved ions from the effluent coming from soap, cement, sawmill industries located in the area. The alkalinity value recorded ranged between 3.00 to 19 mg/L. The values obtained in all the sampling sites are well below the limit. Seven out of the ten sites had total organic carbon (TOC) higher than the acceptable limit. Analysis of variance (ANOVAs), Pearson correlation and principal component analysis (PCA) were used to evaluate the data.
