Abstract (in english)
   A range of long-standing contamination problems in the Czech Republic have been addressed since 1992. The major task is the removal of chlorohydrocarbons, mainly 1,1 dichloroethylene (1,1 DCE), 1,2 dichloroethylene (1,2 DCE), 1,1,2 trichloroethylene (TCE) and 1,1,2,2 tetrachloroethylene (PCE), from both groundwater and the unsaturated zone. In the case of the unsaturated zone, the most seriously polluted soils are excavated and removed, while the less affected areas are rehabilitated using venting techniques, the efficiency of which can be assessed by measuring the concentrations of volatile CLHCs in the soil, in the venting system and at the output of the filters. For the saturated zone, it is stripping techniques that are the most suitable and most often applied in groundwater remediation projects. An important supplement to all remediation projects is the monitoring of catchment areas in order to identify sites that remain affected by groundwater pollution.
   The Cretaceous groundwater system, which is the most important aquifer in the Czech Republic, has so far been the main target for research into chlorohydrocarbon decontamination. As a result of government regulations, the remediation of environmental damage caused by industry and agriculture prior to 1989 has been partly financed by the privatization of national industries
