Some Physico-chemical Changes in Surface Water caused by Contamination of Petroleum Oil from the NNPC Oil Pipeline in some Masev Communities in Benue State, Nigeria
The Nigerian National Petroleum Corporation (NNPC) oil pipeline project has left its mark in form of environmental problems in some Masev Communities of Benue State. An extensive area of prime agricultural land has been affected. Spilled petroleum oil is certainly responsible for alterations of surface water physico-chemical properties within the area. From five selected communities which had experienced oil spill, twenty four water samples were collected from surface water within oil spill sites. A similar exercise of surface water sample collection was carried out at three selected sites from three communities, unaffected by oil spill, within the same geographical area, Water chemical and physical property test was carried out in the Benue State Water Board Laboratory Makurdi for the affected and non-affected areas to assess the extent to which the surface water in the affected areas had been influenced by the project. The results of the tests were analyzed using some statistical methods. The result of the analysis showed that surface water in the affected areas were significantly contaminated by oil spillage from the NNPC oil pipeline and this, in turn had affected water resources, the agricultural productivity, and biodiversity within the communities. The laboratory test results were based on FEPA standards. It has been suggested that there is an utmost necessity to take some perfect steps either to control or to minimize the petroleum oil pollution in this area.
