This study evaluates the impact of the compost technology in bioremediation of the crude oil polluted soils in a53-day screen house experiment. The aim of this work was to evaluate the composting technology in the treatment of soils contaminated with weathered hydrocarbons and drilling cuttings commonly placed in repositories under specific regional condition. Oil contaminated soil was collected from Ibadan and worked on. There were two different composts used for the study, they are Poultry Manure and Goat dung with three replicates each. The control was also studied using three replicates to know the impact of the compost on the contaminated soil. Effects of the technology on soil pH, Total Petroleum Hydrocarbon (TPH) and Electrical Conductivity (EC) were investigated. Soil Temperature profiles were taken on daily basis for each system and chemical analyses were conducted using standard procedures. TPH was determined using standard extraction procedures and qualified by UV – Visible Spectroscope at 510nm. The resulted compost technology increased soil pH and EC. The composting technology to remediate contaminated -soils consists in the addition of organic material and periodic aeration so that the biodegradation of hazardous organic pollutants and organic matter is favored in a simultaneous process.
