Sooner or later, all landfills reach capacity. But that doesn’t mean it’s the end of their useful life. By “capping” landfills with synthetic membranes, clay and topsoil, WM converts land surrounding closed disposal sites into beneficial community assets.
Modern Landfills
Today’s landfills are sophisticated, engineered structures that help us secure environmental safety and sustainability.
Engineering the Modern Landfill
At landfill sites across North America, we implement processes and technologies that ensure environmental safety and sustainability goals are met. At some locations, methane gas is harnessed for conversion to renewable energy. The modern landfill begins with a careful evaluation and preparation of the landfill base to assure the stability of the engineered landfill above.
Groundwater Monitoring
WM installs permanent groundwater monitoring stations at all of its disposal facilities, with well placement and designs adhering to American Society of Testing and Materials (ASTM) standards. Continuous monitoring of groundwater and leachate conditions protects the environment and ensures the integrity of capped landfills for decades to come. After closure, monitoring continues according to strict standards, ensuring long-term safety of the modern landfill.

The Leader in Landfill Operations
WM operates the largest network of landfills in the industry, managing the disposal of almost 100 million tons of waste every year. This requires nationwide reach and a forward-thinking approach to mitigate potential impacts from our landfills and ensure the safety of nearby communities.
