摘要：An assessment of aquifer protective capacity was investigated in some towns of Yenagoa. Fifteen (15) Vertical Electrical Soundings (VES) stations were occupied using the Schlumberger electrode configuration. The VES data interpretation involved quantitative modelling and the curve types obtained were HA, KHK, HK, AK, HKQ and KH. The modelled geoelectric parameters (layer resistivity and layer thickness) at each station were used to compute the Dar-zarrouk parameter (i.e. longitudinal conductance LC). Longitudinal conductance values showed areas with poor (less than 0.1 mho), weak (0.1 mho – 0.19 mho), moderate (0.2 mho – 0.69 mho) and good protective capacity (0.7 mho– 4.9 mho). Results showed that 53.3% of the area had a weak aquifer protective capacity, 33.3% had poor protective capacity and 13.3% had good and moderate aquifer protective capacity. The longitudinal unit conductance indicated that the Southern Yenagoa had good to moderate aquifer protective capacity rating, while the Northern area had poor to weak aquifer protective capacity.
