Water quality analysis was conducted using the physical, chemical and biological analysis methods of water treatment for samples randomly selected from three (3) boreholes and three (3) hand dug wells in Uyo metropolis to determine their suitability for drinking in comparison of the WHO standards for drinking water. After the analysis, one (1) of the boreholes was found to be slightly acidic (pH 6.3) while others were within limit of WHO standards. The mean D.O for borehole (4.161mgl/l) were less than that of wells and did not meet the WHO limit. (5-14mg/l). The BOD of all samples did not satisfy the WHO limit of 2-4mg/l. lead concentrations in bored holes were slightly above WHO limits of 0.01mg/l. the concentration of ions (Fe4, Ca2+ and mg2+), sulphate, and Nitrate fell within the WHO limit. From analysis, it will be concluded that the different water sources are good sources of drinking water.
