Project Highlight: In Situ Stabilization in Tight Urban Conditions

Remediating urban sites isn’t just about contaminants—it’s about access, coordination, and timing. At the Gowanus Nevins redevelopment site in Brooklyn, the client faced a tough challenge: stabilize coal tar-related MGP contamination between two 24-story buildings with limited access, dense infrastructure, and over 10 contractors working onsite.

With tight permitting windows, buried obstructions, and no room for error, the risks were high: delays, disruptions, and potential non-compliance with NYSDEC standards could derail the entire project.
Standard approaches wouldn’t cut it—Cascade delivered a purpose-built ISS solution using pre-treatment probing, phased execution, and specialized mixing equipment to navigate these constraints.
