PlumeStop sorbs organic contaminants from aqueous solution rapidly--within hours of application. Pollutants partition directly into the PlumeStop particles that are sorbed to the soil formation, thereby removing the pollutants from groundwater. Contaminant advection in the aqueous phase is therefore eliminated and partitioning into the vapor-phase is also reduced (Henry’s Law). Results can be dramatic, with groundwater cleanup objectives often met within days of PlumeStop application. The principles of contaminant sorption onto PlumeStop are described in Technical bulletin 2.1: Sorption of Contaminants from Solution. The present technical bulletin focuses on the sorptive capacity of PlumeStop within a permeable soil matrix as well as its resistance to wash-out once emplaced.
