The Impact

Waste disposal and management is a challenge in developing countries and has great influence on the groundwater quality. This research aimed at assessing the impact of leachate on nearby wells within the vicinity of active dumpsite in Yaba, Lagos, Nigeria. Four vertical electrical sounding and four electrical resistivity tomography using Schlumberger and Wenner electrode configurations respectively were carried out at the dumpsite. Physicochemical analysis of water samples from neighbouring wells were also conducted. The geo-electric curve showed four different subsurface layers. The electrical resistivity surveys revealed low resistivity values of s uspected leachate between 1.77 and 39.1 Ωm at a maximum depth of 20.8 m from the subsurface. The leachate polluted area is characterized by low resistivity values ranging from 1 to 10 Ωm, the thickness ranged from 0.5 to 9.2 m and the dir ection of leachate flow is from the northeast to southwest of the canal. The physicochemical analysis revealed that SO42- (70 - 89 mg/l) and Cl- (115.7 - 190.5 mg/l) have values within the World Health Organization (WHO) permissible limit. The pH (5.08 - 6.07), Electrical conductivity (774-1028 μS /cm) and the total dissolved solids values fall below WHO limit. The impact assessment of dumpsite effect revealed that the groundwater quality was affected by the leachate flow.
