چکیده	Despite extensive research about soil contaminant interaction, there is limited research on the geo-environmental behavior of smectite with different contaminants while the double layer thickness is remained similar. The main objective of this paper is to study the mechano-chemical behavior of smectite samples which are contaminated with different organic components at a similar double-layer thickness. The experimental study includes a series of unconfined compression tests, Atterberg limits, and XRD tests to address the microstructural changes and engineering properties of contaminated smectite.The results suggest that even though according to the double layer theory the dielectric constant is the major factor which controls soil-organic interaction process, the influence of other characteristics of organic compounds such as molecule weight is the dominant controlling factor. This indicates some of the major limitation of double layer theory for clay-organic contaminant interaction.
