Remedia completes remediation work at Brooklyn’s 175 Third Street Superfund site

By AI, Created 6:16 PM UTC, May 29, 2026, /AGP/ – Remedia says it successfully deployed its Aqueous Catalyst technology at the 175 Third Street redevelopment in Brooklyn’s Gowanus Canal Superfund corridor to reduce hydrocarbons, contamination and odors during excavation. The project highlights how in-situ treatment can help keep construction moving while meeting regulatory and community-safety requirements in a densely populated urban cleanup zone.

Why it matters: - The 175 Third Street project sits inside the Gowanus Canal Superfund area, where redevelopment depends on controlling contamination without disrupting nearby residents and businesses. - Remedia’s approach is meant to treat impacted soil before excavation releases vapors and odors into the air. - The project shows how in-situ remediation can support construction schedules, compliance and community trust at complex urban brownfield sites.

What happened: - Remedia deployed its patented Aqueous Catalyst technology platform at the 175 Third Street redevelopment site in Brooklyn. - The work covered hydrocarbon mitigation, contamination stabilization and odor control during remediation and material handling. - Charney Companies is the general contractor on the project. - Impact Environmental is providing environmental consulting services. - The site is within the Gowanus Canal Superfund corridor, one of the most closely watched environmental cleanup zones in the U.S.

The details: - The Gowanus Canal has been a U.S. Environmental Protection Agency Superfund site since 2010. - The corridor has a long history of industrial use, including manufactured gas plants, chemical processing facilities and petroleum storage operations. - Remedia says the Aqueous Catalyst platform is designed to address contamination within the soil matrix before excavation disturbs impacted materials. - The system was used for hydrocarbon mitigation and stabilization before and during material handling. - The platform also addressed VOC suppression, off-gas control, coal tar and petroleum impacts, and odor mitigation. - Remedia says treating soil in place reduced off-gassing potential and lowered the concentration of volatile compounds released during excavation. - The approach also reduced reliance on secondary controls such as foam applications and tarping. - The project team was able to handle soil more efficiently and keep the construction schedule on track. - The integrated odor controls were intended to protect nearby residential buildings, commercial establishments and public spaces from nuisance odors. - The technology was used as a compliance tool to help the project align with EPA standards, New York State Department of Environmental Conservation protocols and New York City Department of Environmental Protection requirements.

Between the lines: - Traditional reactive controls such as tarping, foam suppression and perimeter air monitoring can be less effective on sites with dense, mixed contamination. - Source-level treatment shifts the work upstream by trying to neutralize contaminants before they become an air-quality or odor problem. - In a neighborhood with new housing and retail growth, odor complaints can quickly become a project and public-relations issue. - The result is not just environmental control, but fewer work stoppages, less material use and more predictable execution.

What’s next: - Remedia says it is active at multiple Superfund and brownfield sites across the eastern seaboard and beyond. - The company plans to keep applying the same in-situ treatment approach on projects involving former industrial complexes, decommissioned fuel storage sites and urban infill developments. - As Gowanus redevelopment continues, similar remediation strategies are likely to remain central to moving projects forward safely and compliantly.

The bottom line: - Remedia is positioning its Aqueous Catalyst platform as a practical way to clean up contaminated urban sites without slowing construction or triggering neighborhood disruption. - More information is available in the company’s announcement.
