Phytoremediation of organic and nutrient contaminants
Article Abstract:
One of the most promising technologies for treating contaminated soils and sediments involves the use of vegetation. Called phytoremediation, this new technology remediates organic pollutants by the direct uptake of contaminants, the release of exudates and enzymes which stimulate microbial activity and the mineralization of the root-soil interface. Although cost comparisons with techniques such as soil venting and bioremediation is still not possible, tests tend to show that phytoremediation would cost much less than other existing methods.

Integrated in situ soil remediation technology: the lasagna process
Article Abstract:
A modified in situ remediation based on the lasagna process was developed to improve the treatment of contaminated soils and groundwater. The approach, which integrates electrokinetics with sorption and degradation in treatment zones of the contaminated soil, could treat contamination due to organic and inorganic compounds and mixed wastes. Testing results showed that the process is an effective alternative for treating contamination in low-permeability soils.

Decontaminating soil with enzymes: an in situ method using phenolic and anilinic compounds
Article Abstract:
A soil decontamination technique, which would treat xenobiotics that have been transformed into toxic chemicals, involves binding halogenated phenols and anilines to humic material. The binding process is enhanced by enzymes and catalysts because these materials help improve the oxidative coupling of aromatic compounds. The binding reactions are affected by environmental factors such as soil acidity and the chemical structure of the chemical constituents.
