？？ Contaminant retention on geosorbents is controlled by their physicochemical properties, their structural pattern as well as the properties of the contaminants themselves.？ The properties of these adsorbents control their capacity to retain release contaminants in thesubsurface environment

？Contaminants may reach the subsurface liquid phase directly from a polluted gaseous phase, from point and nonpoint contamination sources on the land surface, from already polluted groundwater, or from the release of toxic compounds adsorbed on suspended particles.？ Moreover, disposal of an aqu...

？Volatilization (also referred to as vaporization or evaporation) is the conversion of a chemical from the solid or liquid phase to a gas or vapor phase.？ The partitioning of a volatile compound in the subsurface environment comprises two distinct patterns: volatilization of contaminant molecul...
