Do landfills smell?
Summary. Landfills can produce objectionable odors and landfill gas can move through soil and collect in nearby buildings. Of the gases produced in landfills, ammonia, sulfides, methane, and carbon dioxide are of most concern. Ammonia and hydrogen sulfide are responsible for most of the odors at landfills.
How do landfills affect animals?
As well as the direct effects on animals, landfills are having an indirect effect on them too. The chemicals contaminate plants and waters, which are then consumed by animals lower in the food chain. This contamination at the very root of the animal hierarchy means that all species in the food chain could be affected.
How do landfills harm the environment?
Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.
Can a landfill be built in an environmentally sensitive area?
Landfills cannot be built in environmentally-sensitive areas, and they are placed using on-site environmental monitoring systems. These monitoring systems check for any sign of groundwater contamination and for landfill gas, as well as provide additional safeguards.
How does landfill gas get to the collection header?
Landfill gas (LFG) is a natural byproduct of the decomposition of organic material in landfills. The most common method is drilling vertical wells into the waste mass and connecting the wellheads to lateral piping that transports the gas to a collection header using a blower or vacuum induction system. Horizontal trench systems are useful
What is the purpose of a modern landfill?
Modern landfills are well-engineered and managed facilities for the disposal of solid waste. Landfills are located, designed, operated and monitored to ensure compliance with federal regulations. They are also designed to protect the environment from contaminants, which may be present in the waste stream.
