Challenge Dense non-aqueous phase liquids (DNAPL) of Tetrachloroethylene (PCE) had migrated through 11 m of clay till into a sandy groundwater aquifer. The aquifer is confined by the low-permeable clay till layer and is remarkably high-yielding. The contamination was situated beneath a dry clean- ing facility in which activities had to remain in operation throughout the whole remediation period. The project addressed numerous complexitie
