Soil contamination has now become one of the major concerns over the past few decades. It has increased the concern over help and ecological imbalance, which has lead to the need for cost-effective remediation techniques for soil contamination. The use of plants and introduction chemical oxidants to contaminated soils are found to be extremely effective degrading several types of contaminants including polyaromatic hydrocarbon (PAH), high organic contents, metal concentrations, chlorinated compounds, polyvinyl chloride (PVC) and others. This paper deals with studying three types of contaminated soils, viz; Hospital waste contaminated soils, chemical fertilizer contaminated soil and slurry waste contaminated soils and their remediation techniques using chemical reagents including Condy’s crystals and sodium Hydroxide and phytoremediation using Arrowroot plants. It was found that chemical reagents are more effective than phytoremediation in concern with contaminant reduction and time. Remediation using Condy’s crystals gave best effective results than with other two remediation techniques for the differently contaminated soils.
