Aquifer transmissivity and protective capacity of the overlying rock materials in Agbarho Otor area, Delta State Nigeria was studied. The aim is to evaluate the potential to contaminant seepage employing the Da Zarrouk parameters. Fifteen (15) Schlumberger vertical electrical sounding stations were occupied. The results obtained show a lithology of predominantly sand of various grades with no significant delineable clay intercalations. Maps of aquifer transmissivity and longitudinal unit conductance show a high transmissivity/porosity of the aquifer and a low protective capacity of the overburden material. The low value of the protective capacities makes the aquifer system in the area highly vulnerable to surface contamination. A high transmissivity value of the aquifer materials implies that the storativity is high and this will enhance the migration and circulation of contaminants within the ground water system. It is concluded that the ground water quality may have been impaired in the area. Hence, Hydrogeochemical analysis should be carried out to ascertain the water quality in the area.
