Case Study: PFAS Removal at Bethlehem, PA Landfill
Implemented the innovative LEEF System® to efficiently eliminate PFAS from landfill leachate. This initiative sets a new benchmark for environmental responsibility & public health protection, further demonstrates the scalable, highly-effective PFAS removal technology.
99.99% PFAS Contaminant Removal Efficiency
PFAS (a.k.a. "forever chemicals") are notoriously persistent & challenging to eliminate from the environment, and their presence in landfill leachate poses significant health risks.
Project
Bethlehem Landfill, a subsidiary of Waste Connections Inc., collaborates with WCG to address PFAS prior to discharge.
Technology
Implemented the LEEF System® to remove PFAS from landfill leachate.
Multi-Stage Process
Using multiple stages of foam fractionation, 99.99% of PFAS is effectively separated and concentrated.
Benefits
Provides environmental safety, low energy consumption, minimal maintenance, and scalability.
Result
A new standard for environmental responsibility & public health protection in the waste management industry.

Discover how the LEEF System® can safeguard your community and simplify your landfill's regulatory compliance.
Patented Technology
The LEEF System® removes PFAS from landfill leachate using foam fractionation. This is a process of injecting air to create bubbles, which attracts PFAS compounds and creates air bubbles that rise to the surface and are separated from the water.
Continuous Flow
Simplifies operations & Increases throughput capacity.
Multi-Stage Process
Primary stripping & polishing stages maintain increased removal rates, preparing to meet regulatory requirements.
Low Residuals
By reaching 10,000x Foam concentration, waste streams that are typically 0.1 - 0.3% of daily capacity.
Minimal Energy
