Application of Geophysics in geo-environmental diagnosis on the surroundings of the Hulene-B waste dump, Maputo, Mozambique

Abstract This study aims to identify superficial and underground heavy metals contamination and outline contamination plumes on the surroundings of the Hulene-B waste dump. The electrical resistivity method was applied in 4 profiles of 400 m, 2D resistivity. The interpretation of the resistivity values allowed to identify three anomalous zones with possible contamination: (i) North (profile 2) with East-West orientation, perpendicular to the waste dump with resistivity values
