Remediation of an industrial landfill with CHC- and vinyl chloride-contaminated groundwater

Remediation of an industrial landfill with CHC- and vinyl chloride-contaminated groundwater

In a former landfill for industrial waste in Southern Germany, St. Georgen, a mixture of chlorinated solvents, heavy metals, cyanides and organic material had been deposited. The groundwater was affected by this because there was no soil protection sealing.
Furthermore, high concentrations of vinyl chloride developed by bioconversion. The groundwater outflow reached over 3,000 µg/l. This situation required a remediation.
For this purpose, Prantner delivered the following systems:

Groundwater treatment:
strippers with catalytic air treatment and air scrubber, multi-layer and activated carbon filters as well as ion exchangers for the post-treatment of groundwater

Soil vapour extraction:
19 extraction wells, 3 extraction systems, catalytic air purification and air purification
