Abstract
Cases of water-associated diseases and deaths have been reported globally especially in
developing countries. Thus, a research was conducted to assess the quality of underground
sources in a growing urban centre, in Osun State, Nigeria. A sample of well water, that each
one was collected from each of the 15 political wards across the five quarters in the town.
Physico-chemical parameters were determined and analyzed using standard laboratory
techniques. Factor analysis was used to determine the dominant water quality parameters.
The results revealed that Nitrate, Phosphate, Sodium, potassium, Calcium, Sulphate, pH,
Total Alkalinity, Total Suspended Solids, Total Hardness and Total Dissolved Solids are
generally within the maximum permissible limits. Temperature, Electrical Conductivity, and
coliform counts were generally above the acceptable limits. The results showed that
underground water sources are susceptible to contaminations. It is recommended that proper
treatment of the water should be carried out before consumption to safeguard human health.
