What is a landfill?
Answer:
A landfill, also known as a dump, is a site for the disposal of waste materials by burial and is the oldest form of waste treatment. Historically, landfills have been the most common methods of organized waste disposal and remain so in many places around the world.
Landfills may include internal waste disposal sites (where a producer of waste carries out their own waste disposal at the place of production) as well as sites used by many producers. Many landfills are also used for other waste management purposes, such as the temporary storage, consolidation and transfer, or processing of waste material (sorting, treatment, or recycling).
A landfill also may refer to ground that has been filled in with soil and rocks instead of waste materials, so that it can be used for a specific purpose, such as for building houses. Unless they are stabilized, these areas may experience severe shaking or liquefaction of the ground in a large earthquake.
It's a site, typically an old disused quarry or some such, used for the long-term storage of garbage.

A landfill is literally just a place, pre-existing naturally or carved out of the earth, that serves as a dumping ground for rubbish. It is the easiest way to deal with rubbish, but is not exactly kind to the environment.
A landfill is a structure built into or on top of the ground in which trash is isolated from the surrounding environment (groundwater, air, rain). This isolation is accomplished with a bottom liner and or daily covering of soil.
yes, these are all correct answers to what a landfill is..a place to dump trash. but i wanted to add some thigns and tell you that although they aren't exactly environmentally friendly, there is a lot that goes on inside of a landfill to keep it friendlier.
1) Municipal Solid Waste (MSW) is dumped in the landfill in grids. Typically, the waste is filled and a layer of soil is placed over the MSW. Water is sprayed and the next day, MSW is placed on TOP of this.
2) As the material breaks down, it leeches. It produces leachate, a liquid. This liquid is typically pumped into the MSW from top to bottom to speed the degradation process. The byproduct of the trash is used to break down the trash.
3) Landfills are lined with multiple liner systems, typically bentonite clay. this serves as a cap so that the leachate does not travel outside of the landfill and infect the publics water supply.
4) To make SURE that the leachate is not traveling, monitoring wells are installed along the perimeter of the landfill and are checked regularly to make sure that the contaminate levels are under the standard.
Granted there are things that hinder the breakdown of MSW... for example, styrofoam and plastics. We can do our part though in reducing MSW by recycling things... cans, jars, milk jugs, plastics, water bottles, newspaper, magazines.. and you can reuse too. Use your cream cheese and margarine and yogurt containers as a sort of tupperware to store your food, that way you don't have to buy them, and you're reusing.
