Quality Assessment of surface and underground Water in Ipoti-Ekiti, South West Nigeria

The quality of surface and underground water obtained from Ipoti- Ekiti, Southwest Nigeria were subjected to physicochemical and microbiological qualities assessment with a view to determine their level of pollution. The result of the analyses shows that the pH, SO42- and NO3- are below the World Health Organisation’s (WHO’s) recommended limits for domestic water while theCl-, BOD, COD and turbidity are above the WHO standard. Also, parameters like NO3-, SO42-, Cl-, BOD and COD are affected by seasons as their values in the surface water are less at dry season than the wet season. The result of microbiological analysis shows that some of the water samples contain pathogenic organisms and the bacterial counts reveal that the values for wet season for surface water are more than those of dry season. From the study, it could be said that the spring and borehole water are suitable for most domestic uses while other water would require one form of treatment or the other to make them suitable for all uses. Ways to improve the qualities of the surface and underground water in the community to assist government to achieve its Sustainable Development Goals (SDGs) on water are recommended.
