Abstract
Various techniques for remediation of soil and groundwater contaminated by volatile organic chlorinated compounds (VOCs) are developed and applied for many sites. Reactive barrier technique by usingzero-valent iron as tractive agent has applied to remediate VOCs contaminated site. It has developed and used as apassive remediation to prevent contamination leakage. In this repot, test scale field experiment is conducted to clarify the effectiveness of reactive pile using zero-valent iron for VOCs contamination source. Trichlomethylene decomposed from over 200mg/L to regulation revel by iron powder during 2 months monitoring. Zero-valent iron powder is applicable for degrading high concentration of dissolved VOCs, and active remediation by reactive pile technique is applicable for contamination source.
