Phytoremediation) is a relatively new concept and the technology has yet to be extensively proven in the marketplace. Because of this, most information about phytoremediation comes mainly from field and laboratory research. However, the potential of phytoremediation for cheap, simple and effective soil and groundwater remediation is generating considerable interest. Phytoremediation may be used for remediation of soil and groundwater contaminated with toxic heavy metals, radionuclides, organic contaminants such as chlorinated solvents, BTEX compounds, non-aromatic petroleum hydrocarbons, nitrotoluene ammunition wastes, and excess nutrients [38].

It was estimated that it would take approximately 192 and 643 days to remediate the soil and lower reduce theTPH to 1,000 m g / L using the amendments of the reactors, respectively. Phenol is both a synthetically and naturally produced aromatic compound. Microorganisms capable of degrading phenol are common and include both aerobes and anaerobes [59]. Many aerobic phenol-degrading microorganisms have been isolated and the pathways for the aerobic degradation of phenol are now established [59]. The first steps include oxygénation of phenol by phenol hydroxylase enzymes to form catechol, followed by ring cleavage adjacent to or in between the two hydroxyl groups of catechol.

The technology requires the presence of indigenous organisms capable of degrading the contaminants of interest, as well as nutrients necessary for growth. Also, it is necessary that the contaminants be available to the organisms, and not tightly sorbed to soil particles. Bioventing is not as effective in treating areas where the water table is high, and soils with very low moisture content. ELEMENTS OF SUSTAINABILITY AND BIOREMEDIATION 11 Lastly, the technology is not applicable in sites where high concentrations of inorganic salts, heavy metals, or organic compounds are present, as these hinder microbial growth.
