This work assesses the hydrochemical properties of groundwater in parts of Afikpo and its suitability for human uses. Groundwater samples were collected from boreholes for hydrochemical analysis in dry and rainy season. Twelve 12 doublet samples collected in each season were analyzed for various physicochemical parameters and the results compared with World Health Organization (WHO) standard for drinking water. The results indicate that majority of the water samples were within the WHO standard for drinking water. About 11Percentage of the samples were contaminated with Calcium, Magnesium, Lead, Arsenic and Mercury which could be as a result of anthropogenic sources such as poor waste management, poor sewage disposal and application of fertilizer and pesticide.
