SUCCESSFUL LNAPL REMOVAL USING AIR SPARGE/ SOIL …
SUCCESSFUL LNAPL REMOVAL USING AIR SPARGE/ SOIL VAPOUR EXTRACTION TECHNOLOGY Jamie Natusch, , Manager Remediation Services Lynda Smithard, , Senior Remediation Engineer INTRODUCTION The application of Air Sparging (AS) technology coupled with Soil Vapour Extraction (SVE) for the recovery and remediation of Light Non-Aqueous Phase Liquid ( LNAPL ) hydrocarbons presents a number of challenges. AS applicability is governed mainly by geo/hydrogeologic conditions and contaminant type and distribution. It is typically not applied to mobile- LNAPL plumes where the enhanced risk of product migration is not manageable.
