Flow Simulation Of A System Of GroundwaterCirculation Well And Pumping Well For NAPLSite Remediation

Groundwater circulation wells (in German, Grundwasser Zirkulation Brunnen, GZB) have been established as an in-situ flushing method for the remediation of volatile contaminants in groundwater. Here the operation of a GZB with three well screens and numerical modeling of a field operating system of GZB and pumping well, for the remediation of volatile contaminants is presented. The GZB is used for the removal of volatile contaminants in a highly industrial polluted region and a pumping well is provided at the downstream of the GZB in order to capture the existing contaminants in the downstream which is recharged into the GZB. A threedimensional super position model coupled with finite element method is used to analyze the flow pattern between GZB and pumping well. The flow pattern for different quantities of circulation and pumping is also presented.
