【 摘 要 】

The research was conducted in two notable oil producing communities inNiger Delta, South – South geopolitical zones of Nigeria with aim of assessing the impactand recommending a remediation technique for reclaiming the land for agriculturalindustrial, and residential purposes. The communities are; Ajoki Community in Ikpoba –Okha Local Government Area of Edo State and Koko Community in Warri North LocalGovernment Area of Delta State; both communities are located on050 25"E and 60 05"N. Eleven (11) soil samples were collected in and around the oilproducing communities, five from each community and one from Ugbowo Community inBenin City as a control site. The soils were first tested to ascertain the level ofcontamination before the experimental procedure began. The physiochemical parameterswere determined using standard chemical methods of soil determination whileremediation process was descriptive using denitrifying bacteria for 27 days at 7 daysintervals. The results obtained were subjected to statistical treatment using micro softexcel format, the results were presented in tables and in graphs for easy understandingand explanation. The geochemical results show that the pollution was mild while theremediation method adopted yielded a positive result which, however, reduced the soilorganic content, total nitrogen, nitrate and phosphorus.
