Cleanup Objectives:Remediate gasoline-contaminated ground water for 50 to 100 years

Greener Remediation Strategy:

Installed radial-flow engineered wetland

• Insulated with mulch to accommodate temperatures reaching -35o F
• Constructed treatment cell foundation out of crushed concrete reclaimed during refinery demolition
• Located treatment cell below ground to increase operational control and reduce offensive odors and insects
• Employed “Smart Growth” principles to complement conversion of former refinery to an office park and recreational facilities

Results:

• Treats up to 700,000 gallons of contaminated ground water each day,
• Achieves non-detectable concentrations of benzene and other hydrocarbons
• Operates year-round despite cold climate
• Incurred construction cost of $3.4 million, in contrast to $15.9 million for alternative pump-and-treat system employing air stripping and catalytic oxidation
