Why do landfills need to be away from human habitation?

Why landfills should be away from city?

Methane is the leading cause of fires at landfills, resulting in garbage burning which causes severe air pollution. Landfills also pose tremendous health hazards due to them being a storehouse of virus and bacteria, causing cardiovascular and lung diseases.

The leachate from Municipal Solid waste landfills is a highly concentrated “chemical soup”, so concentrated that small amounts of leachate can pollute large amounts of groundwater, leaving it unsuitable for domestic water use.

Where should landfills be located?

Ideally, sites should be located in silt and clay soils that restrict leachate and gas movement. A landfill constructed over a permeable formation such as gravel, sand or fractured bedrock can pose a significant threat to groundwater quality.
