Soil contamination is essentially the introduction of any physical, chemical, biological or radiological substance or matter into it (Adesodun, 2004). Contaminants generally include all solutes (organics or inorganics) introduced into the soil environment as a result of human induced activities regardless of whether or not the concentrations reach levels that cause significant degradation or any harm (Adesodun, 2004). Common forms of soil contamination are spent lubricant oil, crude oil, gas flaring and grease. Once these waste materials enter the soil, they become part of a biological cycle that affect all forms of life.
