MODELING SOIL PH FATE IN CRUDE OIL CONTAMINATED SOIL IN THE NIGER DELTA

Abstract: Environmental degradation issues are of topical concern to communities in the Niger Delta region of Nigeria. Over the years, there has been strong agitation over polluted farm lands in the Niger Delta region by oil companies operating in the area. This is as a result of oil exploration and exploitation in the region. The people in the region can no longer expect good harvest from their farm lands due to oil pollution. This paper is set to investigate the effect of crude oil pollution on soil pH with time. The soil sample collected from the university research farm was artificially polluted with 0.05, 0.1, 0.15, 0.2, and 0.25 liters per kg of soil. The polluted soils were tested using standard methods at 14days interval. The panel Data Regression model (PDRM) was used to analyze the data. The result reveals that the soil pH content of the soil at various level of crude oil pollution varied with time. This can be attributed to mineralization and immobilization processes in the polluted soil environment. Over time, the soil pH content of the control sample was two (2) times lower than the values of soil pH content at various level of crude oil pollution. The high soil pH at various crude oil pollution level could also be due to reduced microbial activity and depressed soil pH mineralization occasioned by the alkalinity of the soil as a result of the carbonaceous substance in the crude oil. A model which can be used as a predictive tool to determine the level of soil pH fate in crude oil polluted soil has been developed.
