Landfill Liner Systems &Environmental Containment
2,600+ active MSW landfills across the US depend on engineered liner systems to protect groundwater and the environment. EFI has 30+ years of landfill liner installation experience.
The Challenge
Protecting Groundwater from Landfill Leachate
Municipal solid waste landfills generate leachate, a toxic liquid containing heavy metals, organic compounds, and contaminants that can devastate groundwater supplies. Federal Subtitle D regulations require engineered liner and leachate collection systems for all new MSW landfills.
Landfill gas, primarily methane, must be collected and managed to prevent explosions, reduce greenhouse gas emissions, and meet Clean Air Act requirements. Proper cap closure systems are essential for long-term post-closure environmental protection.
- Leachate contaminates groundwater if liner systems fail
- Subtitle D and Subtitle C require engineered containment
- Landfill gas must be collected per Clean Air Act regulations
- Cap closure systems must perform for 30+ year post-closure periods
