Cleanup Objectives: Recover hydrocarbons from ground water at RCRA site

Greener Remediation Strategy:

Uses a hybrid system employing solar and wind energy

• Began operating four wind-driven turbine compressors in 2002 to drive compressed air into hydraulic skimming pumps
• Began operating three 55-W photovoltaic panels in 2003 to power some recovery wells
• Added three 110-W photovoltaic panels and two wind-driven electric generators in 2006 to power a total of nine submersible total-fluid pumps and the fluid-gathering system
• Recycles recovered petroleum product by transfer to adjacent oil refinery for use as feed stock

Results:

• Recovered 228,000 gallons of free-product oil (approximately 20% of the estimated volume) by the end of 2006
• Avoids off-site transfer and disposal of petroleum product
