Geoelectric study of Abule Egba, Igando and Olushosun landfills within Lagos municipality has been undertaken to determine their hydrogeologic implications. The field technique involved vertical electrical soundings utilizing Schlumberger electrode array. At Abule Egba, landfill materials are defined by resistivity varying between 1.6 Ω-m at decomposed stage and 144 Ω-m within fresh dump. The Igando landfill is defined by resistivity varying between 2.5 Ω-m at decomposed stage and 26.1 Ω-m at fresh dump. Olushosun landfill is defined by resistivity varying between 2.4 Ω-m at decomposed stage and 51.5 Ω-m at fresh dump. Interpretation of sounding curves showed that Abule Egba is underlain by fairly thick column…
