17.4.6.2 Phytostabilization

Phytostabilization, also known as phytorestoration, is a plant-based innovative
remediation technique that stabilizes wastes and prevents exposure pathways via
wind and water erosion; provides hydraulic control, which suppresses the vertical
migration of contaminants into ground water, and physically and chemically
immobilizes contaminants by root sorption and by chemical fixation with various
soil amendments (Cunningham et al. 1995 ; Salt et al. 1995a ; Berti and Cunn-
ingham 2000 ). It may also serve as an interim strategy to reduce risk at sites where
complications delay the selection of the most appropriate technique for the site
(Fig. 17.4 and Table 17.3 ).
