TYPICAL LINED SANITARY LANDFILL
|
|
(A) LINER SYSTEM
|
Multiple, engineered layers of geosynthetic and natural soil materials underlying the disposal area, and preventing rainfall and other liquids that come in contact with the waste from escaping into the environment and restricting the underground migration of landfill gases. |
|
(B) CAP SYSTEM
|
A vegetated cover placed over the landfill at completion of filling, consisting of geosynthetic and natural soil materials, preventing the escape of landfill gases to the air and restricting the infiltration of rain into the landfill. |
|
(C) GAS MANAGEMENT SYSTEM
|
A series of extraction wells and piping that removes methane and other decomposition gases from the landfill for proper destruction or reuse. |
|
(D) LEACHATE MANAGEMENT SYSTEM
|
A series of pipes placed beneath the waste (and above the liner system) that remove leachate from the landfill for proper treatment. |
|
(E) EROSION AND SEDIMENTATION CONTROLS
|
A network of storm water drainage channels and detention ponds, which remove rainfall from the surface of the landfill before it comes into contact with the waste, and prevents storm water from flowing onto the landfill from surrounding areas. |
|
(F) MONITORING SYSTEMS
|
A comprehensive system of environmental monitoring locations and devices to promptly detect releases to air, surface water and groundwater resources, and to ensure protection of public health, safety and the environment. |
