Teterboro Landing Site Remediation

Like many sites of its era, the 63-acre Teterboro Landing site (formerly Bendix Aviation Corporation) in New Jersey, USA manufactured aircraft technology that supplied both World Wars and the nation’s fledgling space race. Decades of industrial use had left the site’s soil and groundwater with extensive and complex contamination, including TCE, PCE and Freon, in a varied clay formation.

The site is served by an extensive network of interstates, highways and bridges leading to New York City. After securing a grant through New Jersey’s SmartGrowth Program, the client wanted to speed up the project to make way for a $100 million redevelopment program.

Ramboll, in partnership with its client and regulatory officials, developed a remedial strategy using in situ thermal remediation for the areas of greatest contamination, combined with in situ chemical oxidation for the less contaminated zones, and an 800-foot in situ biodegradation permeable reactive barrier as a polishing step to treat remaining impacts to groundwater.

In just over 30 months, Ramboll completed the comprehensive $45 million remedial program, including site investigation, design and remediation of the site, ultimately removing more than 35,000 pounds of chlorinated volatile organics over 3.2 acres and depths to 40 feet, making the program one of the largest in situ thermal remediation projects completed to date.
