Due to human activity and other natural influences, drinking water is seldom found in 100% pure forms in nature. Drinking polluted water is a major source of sickness in underdeveloped nations. The United States Environmental Protection Agency (USEPA) and standard methodologies for the investigation of water and wastewater were followed in the analysis of the collected water samples, which were conducted using automated instrumental methods. The obtained results indicated that the samples used had the following ranges of concentrations: SO₄^2- ranges from ND to 19.00 mg/L; NO₃^-  ranges from 4.40 to 100.32 mg/L; PO₄^2- from 2.02-11,34 mg/L; pH 6.64 to 7.70; Cd from 0.0020 ± 0.001 to 0245 ± 0.01 mg/L; Ni, from 0.0074 ± 0.003 to 0.848 ± 0.021 mg/L; Cr, ND to 0.386 ± 0.082 mg/L; Pb ND to 0.428 ± 0.003 mg/L; total bacteria count TaBC, 4 x 10² to 3.3 x 10⁴ CFU/mL. Most of the physicochemical parameters were above acceptable limits. The bacteriological study of the water samples also revealed that the water samples were all polluted with bacteria and coliforms. From the foregoing, these drinking water sources, therefore require treatment before consumption to minimize or avoid the incidences of water-related diseases.
