In rhizofiltration, plants are effective only if their roots are exposed to contaminated soil. C. Phytostabilization reduces contaminant mobility, but the total pollutant load in the soil remains unchanged. D. Bioventing involves the injection of air or oxygen into soil to stimulate aerobic microbial degradation. E. During in situ bioaugmentation, the remediation is achieved by physically removing contaminated soil for off-site treatment and replacing it with decontaminated soil.
