Feasibility Studies of Soil Remediation for Kenya

Soil remediation technologies have been developed to remediate the contaminated soil. There are several types which categorized into physical/chemical, biological and thermal methods. Physical/chemical method involves physical removal and uses of chemical to destroy, separate, or contain the contaminations, biological method uses plants and some microorganisms to degrade pollutants accumulated in the soil, while thermal uses heat energy to treat contaminated land. The main objective of this report is to analyze the remediation technologies that are feasible to be implemented in Kenya by the use of summarized studies done by environmental expertise in UK. By comparing cost and time used to implement each of the technologies, the study found out that eight technologies are most feasible technologies identified after analysis. These technologies are soil washing & separation, soil flushing (In situ), Vitrification (In situ), chemical oxidation and reduction (Ex situ), vitrification (Ex situ), phytoremediation (In situ), permeable reactive barrier (In situ) and thermal treatment (Ex situ) that likely to work well for the remediation of contaminated soil in Kenya.
