Despite our efforts to reduce, reuse and recycle waste, more than half of the garbage generate ends up in landfills. Landfills are designed, sited, engineered, operated, regulated, tested and monitored in a safe and environmentally responsible manner. It is a carefully designed and monitored facility that protects the environment (e.g., groundwater, air, surface water). This is accomplished through the use of liners and daily covering of soil. Landfills are carefully filled, monitored and maintained while operating. The monitoring continues long after they close. Permitting a modern landfill generally takes years – sometimes as long as a decade, costing millions of dollars due to the rigorous siting, engineering and environmental requirements necessary to demonstrate and ensure regulatory and safety concerns are satisfied.
