About the Project

The 68th Street Dump encompasses a 239-acre area and encompasses multiple landfills. After accepting industrial and commercial waste for years, the site was recently designated as a Superfund site, necessitating a comprehensive remediation strategy.

GEOWEB® for Landfill Cap

51,000 square feet of the landfill (all slopes steeper than 3:1) was capped using GEOWEB® GW30V 12-inch depth geocells, infilled with topsoil.

GW30V12 was the perfect solution to the site because it isolated the hazardous material, ensured compliance with the EPA’s 12-inches of cover requirement, successfully managed the steep and complex topography, and provided a durable solution that could provide lasting erosion protection against environmental conditions.
