Abstract—This study aims at evaluating the hydro-geological/hydrological conditions to measure the water levels/surface water conditions in Southern Ijaw Local Government Area of Bayelsa State passing through the following communities: Buluo-Orua, Toru-Orua, Kabiama, Amatolo, Okumbiri, Toru- Egeni and Toru- Ebeni. The investigation was carried out to ascertain the hydro-geological/ hydrological characteristics in the area. Water levels recorded in the site BH-1(1.0m), BH-2 (0.5m), BH-3 (2.0m), BH-4 (0.5m), BH-5 (1.0m) and BH-6 (2.0m), respectively. The physicochemical properties of surface water and groundwater in the area measured are within permissible limits, except pH and iron which needs treatment. All the heavy metals, except Co and Fe show values <0.01mg/l. Coliform counts of groundwater in these areas exceed the WHO (2011) guide value of 0cfu/ml and are generally unsafe for drinking. The low value of TSS in the area in site is due to very high static water level (SWL). Coliform counts of groundwater in the areas exceed the WHO (2011) guide value of 0cfu/ml and are generally unsafe for drinking. The groundwater pH should be treated with sodium bicarbonate to reduce the acidity content. Owing to high iron concentration, filtration process should be carried out to remove Iron. It is recommended that a regular monitoring and assessment of groundwater in the area is necessary to ensure that the quality is within regulatory limits.
