Soil pollution causes different negative chain reactions, that can lead to environmental catastrophes. In the world. Nigeria is one of the biggest oils producing regions in the world, but Niger Delta has suffered and still experiencing serious oil spills covering large areas. Which become one of the most polluted places on the earth.
This thesis focuses on testing remediation technology, that uses microbes capable of degrading petroleum hydrocarbons. That technology offers combined remediation of petroleum hydrocarbon for the contaminated soil and groundwater treatment. The remediation is started by non-toxic bio activators and high-performance enzymes, bioremediation solution is mixed with the excavated soil. The electrokinetic oxidation solution covers the whole polluted soil volume, further enhancing the bioremediation.
The aim is to restore the soil and maintain the optimal environmental conditions for the area, by applying efficient remediation technology to meet the goals set by the authorities. The target value of Total Petroleum Hydrocarbon (TPH) was set to 50 mg/kg.
In this study remediation technology was tested on polluted soil samples from depths of 3 to 5 meters. Applying the remediation of hydrocarbon technology, the TPH level was lowered below the set target value, the highest level remaining at 23,2 mg/kg and the lowest at 2,6 mg/kg. Based on the results, this remediation technology is proven to be efficient to turn polluted soil suitable for agricultural use.
