MONITORING OIL SPILL REMEDIATION USING GEOGRAPHIC INFORMATION SYSTEM: CASE STUDY OF THE OGONI CLEAN-UP IN RIVERS STATE, NIGERIA.

This research was carried out based on the need for creating a digitalized environmental resource database for Ogoni (comprising its four Local Government Area of Eleme, Khana, Tai and Gokana in Rivers State, Nigeria). Leveraging on the Engaged techniques in monitoring oil spill Remediation management. The research was proposed towards monitoring Remediation with various degrees of impact resulting from oil spill contamination within the study area, through the knowledge of spill sources, contaminated area, degree of impact and sizes, from which a viable database is built. List of the impacted 64 UNEP facts sheets sites, list of 12 sites undergoing Remedial work, spill investigation area and their reference GPS coordinates as provided by HYPREP was analysed using the Geographical Information Systems. collected dataset was analysed using ArcGIS 10.5 as imported in Geographical Information Systems environment, suffer was used in producing maps and contour. Indications from result shows that each impacted site, has an associated source with the contour showing point of high and low impact of contamination. The research has therefore conclusively shown the effective use of Geographical Information Systems, in creating a spatial database in monitoring and modelling oil spill trend for the purpose Remediation putting in place adequate Remediation Management System in the study area. I recommend that Remediation Management System maps covering study area be consistently made available and accessed when needed for upward review.
