Title: Proof-of-Concept of the Phytoimmobilization Technology for TNX Outfall Delta: Status Report

Technical Report ·
DOI:https://doi.org/10.2172/783813· OSTI ID:783813

A series of proof-of-principle studies was initiated to evaluate the soil remediation technology, phytoimmobilization, for application at the TNX Outfall Delta (TNX OD) operable unit. Phytoimmobilization involves two steps. The first step is entitled phytoextraction, and it takes place mostly during the spring and summer. During this step the plants extract contaminants from the sediment into the roots and then translocate the contaminants to the above-ground plant parts. The second step is referred to as sequestration and it takes place largely during the autumn and winter when annual plants senesce or perennial trees drop their leafs. This step involves the immobilization of the contaminant once it leaches from the fallen leaf.
