Old Environmental Hazards

Old Environmental Hazards

In 2006, in the wake of negotiations with the Czech Environmental Inspectorate, Czech Airlines and Prague Airport decided to clean up an old environmental hazard in the vicinity of Hangar F, which was caused in the past by a leaky underground tank.  In the 1970s, this tank was used to store chlorinated hydrocarbons and oil products.  The cleanup work lasted from June 2006 to the end of 2006 and used the extraction of contaminated soil gas (i.e., the venting method) with subsequent incineration in a catalytic oxidation facility.  The results of the latest analyses of samples indicate that, compared to the situation in August 2006, there has been a significant reduction in the concentration of pollutants in the groundwater and soil gas.  On completion of the cleanup work, a risk analysis was conducted, which will be used as a basis for the planning of further steps.
