Abstract
The remediation of contaminated groundwater by zero-valent iron Permeable Reactive Barrier(Fe0-PRB) was discussed and summarized.It was proved that the approach is characteristic with in situ remediation,good long-term performance,many remediable contaminants and low costs.And big progress has been made recently in remediation mechanism,design and construction of the system,the reactive materials and application in practical projects.It was also analyzed the technical difficulties and limitation of the approach.The researching emphases were analyzed at last to initiate a pilot study of the approach in China.
