Contaminants removal stoked inside low permeability zones of aquifers is one of the most
important challenge of groundwater remediation process today. Low permeability layers can
be considered persistent secondary sources of contamination because they release
pollutants by molecular diffusion after primary source of contamination is reduced, causing
long plum tails (Back-Diffusion). In this study, the Groundwater Circulation Well (GCW)
system was investigated as an alternative remediation technology to the low efficient …
