Abstract: Groundwater has proven to be a valuable resource for the local population of developing countries. Medical hydrogeology, a concept that primarily studies the positive and negative health effects of minerals in water has rarely been studied in Nigeria. Hence, we quantified the percentage of recommended daily intake (RDI) of calcium (Ca), magnesium (Mg), and chloride (Cl−) in connection with groundwater physicochemical parameters occurring in groundwater wells found in Enugu Metropolis, Nigeria. The results showed that groundwater wells in the metropolis are deficient in Ca, Mg, and Cl− minerals. Even though the groundwater physicochemical parameters were within the WHO limits, lead (Pb) and acidic pH concentrations exceeding the WHO limits were observed in over 80% of sampled locations. Consequently, we conclude that groundwater in the metropolis is not a good source of Ca, Mg, and Cl− intake and harbours noxious Pb and pH levels.
