Filling Station Remediation in Leopoldsdorf
Contamination in the saturated and unsaturated groundwater zone of the geological underground on a filing station site
Pollutants: gasoline, mostly BTEX
Investigation, preparation of a remediation plan and performance of Ex-Situ and In-Situ remediation measures
Dimensions of contaminated area: ca. 800 m²
Ex-Situ Measures: excavation in the area of the unsaturated soil zone (well remediation)
In-Situ Measures:
Immediate Measures: securing and stabilisation of the contamination flag using hydraulic measures. Installation of the depression well, “pump & treat” remediation technology followed by wet activated-carbon filter cleaning. Additional treatment of the groundwater surface using an oil phase pump. Groundwater remediation: removal of the pollutant from the aquifer using combined hydraulic measures (pump & treat) and IAS (In-Situ Air Sparging). Remediation is performed by three remediation wells (total capacity 12 L/Sec), 10 suction pipes, 15 injection pipes and 8 combined pipes.
The remediation unit (container) can be remotely controlled.
