Abstract: Soil contamination is caused by the presence of manmade chemicals in the natural soil environment. It is often caused by some form of industrial activity, agricultural chemicals or the improper disposal of waste. The most common chemicals involved in soil pollution are petroleum hydrocarbons, pesticides, lead and other heavy metals. Heavy metals are among the major environmental pollutants and the accumulation of these metals is a great concern in agricultural production due to the toxic effects it has on crop growth. Remediation of soil is a challenging process but if done perfectly it can yield very good results. The physical and chemical properties of the soil are tested. Test such as sieve analysis, liquid limit, plastic limit and specific gravity are done to understand the characteristics of the soil. The contaminants and their concentration in the soil is identified using SEM ANALYSIS and EDAX. Remediation of soil can be done using micro organism, chemicals, plants, high voltage current or by other physical means. Use of micro organisms is one of the advanced methods of remediation. Microbes, aerobes, anaerobes and facultative anaerobes have been contributing to soil improvement for billions of years. They help with nitrogen fixation, limiting growth of plant pathogens, and decomposition of heavy metals, pesticides and hydrocarbons in the soil. The remediated soil can even be used for construction purposes.
