Water is the second most important basic need of man after oxygen which is the first. The quality of life in villages and cities depends on the regular supply of pure and unpolluted fresh water. The quality of water bodies depends on their physicochemical and microbial characteristics. The hand-dug wells and boreholes are charactacterised as groundwater under this study. Sampling was done on 21 points containing wells and bore holes within part of Mokola-Eleyele in order to assess their physiochemical contents. The sample was collected during September 2018 - February 2019. Laboratory analysis was carried out on them. The physical and chemical contents observed are; pH, total dissolved solids (TDS), Calcium (Ca2+), magnesium (Mg2+), Chloride (Cl-), Sulphate (SO4+), Nitrate (NO3+) and iron content (Fe2+) were analyzed for each water sample collected. The values of physical and chemical contents were compared with the standard values set by the Standard Organization of Nigeria (SON) and the results were within their safe limits. The t-test analysis carried out showed the correlation between chemical contents at 90%, 95% and 99% confidence level, the results shows that the significant differences exist for the parameters. It can be concluded that the qualities of both hand dug wells and boreholes water samples were suitable for human consumption.
