GROUNDWATER QUALITY ASSESSEMENT IN IGUIHEYA COMMUNITY, BENIN CITY, SOUTHERN NIGERIA

ABSTRACT

Groundwater quality assessments of Iguiheya community in Ovia North East Area of Southern Nigeria have been carried out. This is to ascertain its potability. A total of six (6) boreholes were assessed for physiochemical parameters using Atomic Absorption Spectrometer (AAS modern 969 unicam series). The results show that there was a high concentration of hexavalent chromium across the wells. The study suggests that further research should be carried out to ascertain the course of the high concentration of the hexavalent chromium. Generally, the water quality can be said to be potable as a result of all other parameters being below the threshold value besides hexavalent chromium using both WHO and Nigerian Drinking Water Standards.
