USING AIRLIFT PUMPING AS AN IN-SITU AQUIFER REMEDIATION TECHNIQUE

The global attempt to protect and restore the major water resources en couraged hydrologists to develop new, simple and effective aquifer rem ediation methods. A new in-situ remediation procedure is proposed to r emove Volatile Organic Compounds (VOC) dissolved in groundwater. This is accomplished by injection of air into a well, using a combined tech nique of air-lift pumping with a form of vapor stripping. The feasibil ity of the proposed method was analyzed using concepts of mass transfe r of VOCs from water to air-bubbles and transport of VOCs in porous
