With the frequent reports of oil spillages in the Niger Delta area, there is need to seek for a cost effective method for remediation of crude oil impacted soils. In this research work a mathematical model for petroleum spill absorption from contaminated soil remediation with goat droppings was developed. The field test was carried out on the effect of nutrient sources NPK Fertilizer and goat droppings of 1, 5, 10, 20 and 50g added to crude oil contaminated soil in 20 polyethylene bags at random design. The treatment samples were tested at 2 weeks interval for 10 weeks. It was observed that the application of goat droppings was able to ameliorate the levels of total hydrocarbons form 7568mg/g to 439mg/kg as against 500mg/kg produced by NPK fertilizer which indicates a better remediation in goat dropping application. The model developed can be used to generate the level of reduction of the Total Hydrocarbon with respect to time. The predicted residual concentration of THC was compared with the measured values which show a very strong correlation 0.932 and 0.937 for F1 and F2 respectively at 50g. The rate of degradation was computed as follows; 0.016 and 0.054 days-1 for F1 and F2 at 50g. The study revealed that goat droppings can degrade THC faster than NPK fertilizer.
