  Electrical resistivity method was used to investigate the open dumpsite at Gosa, Abuja in order to determine the vulnerability of the groundwater in the area as well as the surrounding environment to leachate contamination. A total of sixteen (16) vertical electrical sounding points with maximum current electrode of 100 m were investigated. The data were analyzed and used to establish the parameters required to fulfil the objectives of this research. A maximum of four geoelectric sections were identified in the area. They included sandy topsoil, clayey sand, weathered basement and fractured/fresh basement. Apparent resistivity values obtained for the four layers delineated were between 64.6 Ωm and 215.5 Ωm for the first layer; 19.0 Ωm and 295.6 Ωm for the second layer; 66.9 Ωm and 1003.7 Ωm for the third layer; and 438.0 Ωm and 1719.9 Ωm..
