Hydrocarbon contamination is commonly associated with abandoned wellsites. The cause of this
contamination can be related to drilling waste material and/or the result from operations which took place on the site. Prior to the commencement of land reclamation, these sites often require an appropriate treatment to enhance remediation and degrade the hydrocarbon which is present in the soil. Landfarming is a recognized approach in the bioremediation of hydrocarbon contaminated soil. This land treatment method involves cultivating the soil surface and is normally aided with fertilizer amendment to provide a nutrient source for the microbial population involved in the degradation of hydrocarbon.
It has been generally found that landfarming is a viable approach to the bioremediation of contaminated sites. However, several factors including landscape, soil properties, and chemistry need to be taken into
consideration to ensure the success of this form of land treatment.
