Phytoattenuation, a novel green remediation concept, has been successfully demonstrated while
employing vetiver and biostimulator (gibberellic acid GA3 and indol-3-acetic acid IAA) to gradually
mitigate soil Cu levels. The effectiveness of stimulator GA3 and IAA was in the descending sequence
GA3> IAA. Biostimulator has been demonstrated plant growth enhancement and been employed for
agricultural operation. The on-site tests demonstrated Cu levels were gradually deceasing during one
month monitoring time periods. The soil metal level reduction achieved a satisfactory level which
complied with local environmental standards. After more rounds of planting and harvesting, the soil
metal concentration expected to be further dropped while on-site operation was executed. Green
remediation concepts such as phytoattenuation need to be taken as serious concern while the Earth
has faced recent unpresdent damage Japan tsunami, Green house effect, unpredicted weather
fluctuation worldwide, and serious endangered specie issues.
