Oil exploration and production activities can cause severe environmental damage due to crude oil discharges to the environment. Remediation of impacted environment follow a general framework hinged on legal/regulatory framework and site specific risk assessment of the levels of contaminants present. Within this general framework of regulations, site specific constraints and cost-effectiveness, the best available technique (BAT) for remedial actions is usually proffered. In this study case of crude oil contaminated soil remediation, composting of the contaminated soil in bio-piles using wood shavings (saw dust) as bulking agent and a commercial product as source of both commercial microbial inoculums and nutrient (N, P, K), was adopted. The major activities in this project involved composting in windrows, broadcasting of the nutrient source and laboratory monitoring. The Total Petroleum Hydrocarbon (TPH) degradation was most rapid during the first 5 weeks of the remedial activities and thereafter followed a typical first order degradation curve. After, 22 weeks of treatment 93% from 3830mg/kg dry weight to 268.1mg/kg dry weight degradation of TPH of the contaminated soil was achieved and a corresponding increase in number of bacterial populations was also observed.
