Cleanup Objectives: Remove volatile organic compounds (VOCs ) from soil serving as a contaminant source within a 2-acre landfill
Green Remediation Strategy: Rely on wind-driven vacuum process rather than electrically powered air blowers for soil vapor extraction (SVE)
- Delineated an unsaturated area with VOC contamination that remained after conventional capping and upgradient ground-water diversion
- Installed a single windmill (with 12-foot blades) to extract VOCs for aboveground carbon treatment
- Constructed a vacuum system enabling windmill blade rotation to reciprocate a single 10-inch air cylinder fitted with check valves
- Connected the cylinder intake piping to a network of nine gas vents on the landfill cap
Results:
- Avoids air emissions associated with consumption of grid electricity during soil treatment
- Generates 85 ft3/hr of vacuum capacity per mph of wind
- Capitalizes on wind intermittency to provide the pulsed effect that is typically effective in venting operations
- Reduced VOC concentrations in soil gas more than 90% over five years
- Removed 1,500 pounds of total VOC mass over the same period
- Recovered $14,000 in capital costs for the wind system within one year due to avoided electricity
- Accrues annual O&M costs below $500, in contrast to potential $75,000 for a conventional SVE system
Property End Use: Long-term landfill containment
