Seneca Meadows And The Water & Carbon Group Partner To Deliver New York's First Full-Scale Foam Fractionation System For PFAS Treatment In Landfill Leachate

Seneca Falls, NY – Seneca Meadows, Inc. (SMI), a Waste Connections company (NYSE: WCNX), has partnered with The Water & Carbon Group (WCG) to design, build, and operate New York State’s first fixed-plant PFAS leachate treatment system.
The 300,000-gallon-per-day facility will establish a new standard for environmental protection and proactive landfill management across the region.
The system will employ WCG’s patented LEEF System® (Low Energy Foam Fractionation) – a technology that uses fine air bubbles rather than chemicals to separate and concentrate PFAS compounds from landfill leachate. Engineered to handle complex leachate chemistries, the process achieves high removal efficiencies while maintaining low energy demand and minimal residual generation.
“This project represents a significant step forward for both Seneca Meadows and New York State,” said Nick Ganzon, US President for the Water & Carbon Group. “SMI’s leadership on this issue demonstrates that responsible operators aren’t waiting for regulation, they’re acting now to ensure lasting environmental protection.”
A Proactive Approach to an Industry-Wide Challenge
SMI operates a regional solid waste management facility serving municipalities, businesses, and industries through environmentally responsible disposal and recycling services.
SMI is a passive receiver of PFAS, which enter the waste stream through everyday consumer products such as packaging, textiles, cosmetics, cookware, and cleaning agents. While SMI does not manufacture or use PFAS, SMI has chosen to take this important step as an environmental leader in the community and the industry.
“The Seneca Meadows team is very proud of our track record investing in and implementing industry leading technologies that achieve our incessant goal to provide the safest, best‑in‑class environmental protections before regulations require,” said Kyle Black, District Manager at SMI. “This project reflects our team’s continued drive and financial commitment to do what’s right before it is required, to listen, to learn, and to keep improving the way we safely manage and protect our environment, our team, our neighbors, and the communities we serve.”
Proven Platform, Expanding Impact
The Seneca Meadows project builds on the success of the Bethlehem Landfill LEEF System® in Pennsylvania, the first full‑scale fixed‑plant PFAS leachate treatment system using foam fractionation in the United States. Commissioned in July 2024, that facility has demonstrated consistent, reliable PFAS removal performance under varying seasonal and flow conditions.
Together, these projects underscore The Water & Carbon Group’s record of delivering turnkey, low‑energy PFAS treatment systems that are reliable, cost‑effective, and adaptable to different leachate chemistries and regulatory requirements.
