Geophysical investigation of the effects of waste dump on groundwater quality in Rukpokwu, Port Harcourt Metropolis

Vertical Electrical Sounding (VES) was carried out in Rukpokwu, Obio/Akpor Local Government Area, Rivers State, Nigeria to investigate the effect of waste dump on groundwater quality study area. An ABEM SAS 300 terrameter used. Schlumberger configuration adopted for sounding acquire a 4 point data, and at Rukpokwu adjudged be free from dumps which served as control. The result resistivity survey interpreted by IPI2WIN computer software, revealing subsurface lithology, thickness prolific auriferous zones, curve types zones contamination. Niger Delta has shallow water table makes it prone easy Different values were obtained; high are an indication uncontaminated lithologic while low contaminated dissolved ions metals decomposing through biochemical reactions, hydrolysis, oxidation reduction processes subsequently leads formation leachate. This leachate is hydraulic continuity with flow eventually Therefore geophysical essential necessary before borehole drilling project order ascertain depth aquifer will give potable
