听Seneca Meadows, Inc. (SMI), a Waste Connections company, has partnered with The Water & Carbon Group (WCG) to design, build, and operate New York State鈥檚 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.听
The system will employ WCG鈥檚 patented LEEF System庐 (Low Energy Foam Fractionation) 鈥� 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.听
鈥淭his project represents a significant step forward for both Seneca Meadows and New York State,鈥� said Nick Ganzon, US President for the Water & Carbon Group. 鈥淪MI鈥檚 leadership on this issue demonstrates that responsible operators aren鈥檛 waiting for regulation, they鈥檙e acting now to ensure lasting environmental protection.鈥�听
SMI operates a regional solid waste management facility serving municipalities, businesses, and industries through environmentally responsible disposal and recycling services.听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.听
鈥淭he 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鈥慽n鈥慶lass environmental protections before regulations require,鈥� said Kyle Black, District Manager at SMI. 鈥淭his project reflects our team鈥檚 continued drive and financial听commitment to do what鈥檚 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.鈥�听
The Seneca Meadows project builds on the success of the Bethlehem Landfill LEEF System庐 in Pennsylvania, the first full鈥憇cale fixed鈥憄lant 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.听
Together, these projects underscore The Water & Carbon Group鈥檚 record of delivering turnkey, low鈥慹nergy PFAS treatment systems that are reliable, cost鈥慹ffective, and adaptable to different leachate chemistries and regulatory requirements.听
