Excavation & Landfarming
Removal of soils and placement in an enclosed soil berm with sufficient freeboard to contain heavy precipitation events.
• Removal of source material to prevent contaminant migration
• Backfilling with permeable material enhances soil vapor extraction
• Increased exposure to oxygen accelerates natural attenuation of soils
• Variety of backfill materials available
• Plastic liners can be placed on top to prevent surface air infiltration
