<p>A process of phytoremediation is provided in which the above-ground surface is first amended with stabilizing additives which will react with and blind subsurface contaminants. As the contaminants are brought to the surface through the growth of phytoextracting plants (20), the plants vegetation is left to die in situ. As the plant biomass decomposes, the soil contaminants brought to the surface react with and/or are bound by the soil amendments (10). The soil amendments may further be provided in the form of a geotextile barrier or mat (12) having one or more additive layers present within the mat structure.</p> |
