A remediation technology for contaminated soil and groundwater, an innovative version of pump and treat technology applying a sugar, a cyclodextrin (hydroxypropyl cyclodextrin) for the enhancement of the solubility of organic contaminants. It was developed in the USA and applied with success for remediation of military sites contaminated by e.g. trichloroethylene. Injecting the cyclodextrin solution into the injection wells, the ground water containing the contaminant in enhanced concentration is extracted from the extraction wells and treated by activated carbon or by distillation. The regenerated cyclodextrin solution is re-injected into the ground water.
