Abstract

The hydrogeophysical and hydrochemical analysis of the shallow wells around Ire-Akari area Orita-Obele Akure, Ondo state was carried out to understand the geologic layer constituting the aquifer, its suitability or otherwise as source of potable / drinking water and the tendency of the overburden to naturally protect the aquifer. The result of the hydrochemical analysis showed that most of the physio-chemical and microbial parameters are found within the WHO permissible limit. Also, the overburden serves as the protective capacity to prevent surface infiltration/leachate effect particularly at depth greater than 10 m. Therefore, wells of appreciable depth (> 10 m), well ringed, and covered could serve as source of drinking water with minor treatment.

Key words: Hydro-geological, Hydro-chemical, physiochemical microbial parameters and infiltration/leachate.
