Abstract
Ten vertical electrical soundings (VES) were carried out using Schlumberger electrode array at the locations where hand dug wells are situated within the village of Camp, Abeokuta, southwestern Nigeria. Eleven water samples were also collected from these wells and analysed. The geophysical study reveal that the depths of all the wells were below the standard recommended depth for deep wells in the basement complex area. The chemical analyses of the samples collected showed that the results when compared with the WHO/EPA standards were far below the recommended values for human consumption; which is suspected to have caused the water borne disease prevalent in this community.
