Abstract

This study was conducted in K-Dere, Rivers State, Nigeria to determine the impact of oil spill contamination on soil and groundwater resources in the area. A total of twelve (12) wells were drilled at random to a depth of 10 m using an auger. The method of soil and groundwater analysis involved visual examination and laboratory analysis. Characterization of soils in the area revealed a predominance of fine and medium grained sand underlain by alternating layers of fine, silt and clayey formations. Soil samples from BH-04, BH-05, BH-06, BH-07, BH-07 and BH-11 have a weak to strong hydrocarbon smell and shows light to heavy sheen. Groundwater in all drilled holes was turbid and encountered at depths from 4.27 to 6.37m. BH-06 has a very strong smell and heavy sheen. Free phase hydrocarbon was also found in BH-06. The chemical concentration of Total Petroleum Hydrocarbons (TPH), Poly Aromatic Hydrocarbons (PAH) and BTEX (Benzene, Toluene, Ethylbenzene, Xylene) were determined from the groundwater samples. TPH ranged from
