Modern landfills have a four layered system that consists of a liner, drainage system, gas collection system and the trash itself. Each of these layers are closely monitored to ensure the landfill is safe for the environment as well as the people who work at the site.
What are the features of a landfill?
WHAT IS THE COMPOSITION OF A LANDFILL? There are four critical elements in a secure landfill: a bottom liner, a leachate collection system, a cover, and the natural hydrogeologic setting. The natural setting can be selected to minimize the possibility of wastes escaping to groundwater beneath a landfill.

How are landfills constructed?
Modern landfills are built using a layering system designed to safely isolate waste and monitor any byproducts, leaks and anything else that can harm the environment. Isolating the trash from air and water is vital for preventing contamination. We can learn more about how landfills work by examining each layer.
What factors must be kept in mind while planning a landfill?
