Assessment of Groundwater Quality in Parts of Ijoko Area, Sango-Otta Axis of Southwestern Nigeria. Scientific Review. 5(6); 103-111.2412-2599https://repository.crawforduniversity.edu.ng/handle/123456789/244A total of 26 water samples comprising of well, river and borehole waters were subjected to physico-chemical tests to evaluate its quality. The result of the physical characteristics shows that the average pH value, total dissolved solid and electrical conductivity is 4.9, 1027.31mg/L and 1526.92mg/L respectively. Thus, relatively above the desirable limit for drinking water while the ionic dominance of the major cations and anions reveal high concentration of Na+ and Cl- amidst other ions in the order of Na+>Ca2+>Mg2+> K+ and Cl->HCO3- > SO42- respectively wherein the water was classified as belonging to Na-Cl facies and unsuitable for irrigation purpose.enArticle
