A layer of clay at the bottom of landfills is used to create a barrier to prevent leachate (contaminated water) from leaking into the surrounding soil and groundwater. A layer at the top helps to prevent external water from entering the landfill, which can reduce the generation of leachate. Overall, these clay layers help to protect the environment from the potential pollution that can result from landfill waste.

What is on the bottom layer of a landfill?
The bottom layer of a landfill typically consists of a composite liner made of clay and a synthetic liner like plastic to prevent leachate from contaminating the surrounding soil and groundwater. Below the liner, there may be a system to collect and treat leachate, as well as a network of pipes for monitoring and managing landfill gas.
Why is clay placed at the bottom of a landfill?
Clay is placed at the bottom of a landfill to create a barrier that helps prevent contaminants and leachate (polluted liquid) from seeping into the ground and potentially contaminating the soil and groundwater below the landfill. Clay is effective at creating a natural liner that can help protect the environment from pollution.
How do sanitary landfill sites prevent chemicals from moving into groundwater?
To prevent chemicals from moving into the groundwater, sanitary landfills use plastic liners and compacted clay .
What earth material covering the surface of a landfill would permit the least rainwater to infiltrate the surface?
A material like a high-density polyethylene (HDPE) liner or a geomembrane would be ideal for covering a landfill to minimize rainwater infiltration. These materials are impermeable and provide a barrier against water seepage into the landfill. Additionally, adding a layer of clay or geosynthetic clay liner (GCL) can also help reduce water infiltration.
How is a landfill made?
A landfill is made by excavating a site, lining it with a protective barrier (such as clay or plastic liners), and then systematically filling it with waste materials. Layers of waste are compacted and covered with soil daily to minimize odor, pests, and litter. Once the landfill reaches its capacity, it is capped with a final cover to prevent water infiltration and gas emissions.
What is a landfill lind with?
A sanitary landfill is usually lined with a thick plastic layer and clay.

Why do landfills have liners?
Landfills have liners to prevent waste from contaminating groundwater and soil. The liners act as a barrier to keep harmful substances from leaching into the environment. This helps protect the surrounding ecosystem and human health.
Clay on the bottom of a pond?
Clay and loam are both commonly placed on the bottom of ponds.
Why do they bury the trash in a landfill?
Primarily to add more trash. When the landfill is full, it will be covered with clay and dirt. It will likely become a park and hopefully any contaminates from the trash will remained trapped there forever.
