Project Summary: Oil and Groundwater Contamination Remediation
location:Austria Europe
Issue: Leakage of 20,000–30,000 L of transformer oil contaminating approx. 10,000 m² (4,000 m² of soil, 500 m² / 2000 m³ in the unsaturated zone).
Key Activities:
Multiphase investigation (percussion drilling, groundwater monitoring wells).
Determination of current and historical groundwater currents.
Preparation and implementation of a remediation plan.
Remediation Approach:
Hydraulic In Situ-remediation:
Soil washing in the unsaturated zone using 55 infiltration pipes, clean groundwater, warm water (solar-heated), and H₂O₂.
Pump & Treat: 3 groundwater remediation wells with oil phase removal in 3 wells and 3 stand pipes.
Remediation container with gravel and activated-carbon filters.
Water leaching via drainage shaft.
Oil Recovery: Approx. 12,000 L of transformer oil recovered.
Remediation Duration:
Initial investigations (2002–2004).
Remediation equipment installed (July–Nov. 2007).
Operation ongoing since Nov. 2007; remediation expected to last 5 years.
Services Provided:
Percussion drilling, groundwater monitoring, hydraulic soil washing,
Pump & Treat, remediation container installation.
