What negative impact can landfills have?

Environmental Impact of Landfills

Along with methane, landfills also produce carbon dioxide and water vapor, and trace amounts of oxygen, nitrogen, hydrogen, and non methane organic compounds. These gases can also contribute to climate change and create smog if left uncontrolled.

How does landfill impact on the environment?

Landfills can impact on air, water and land quality. Landfill gas, mainly methane, is produced by decomposing organic waste which contributes to global warming when released to the air. Water moving from, or through, landfill waste forms leachate which has the potential to contaminate nearby surface and ground water.

This contamination at the very root of the animal hierarchy means that all species in the food chain could be affected.

How do landfills affect global warming?

Due to the aerobic and anaerobic degradations, greenhouse gases like methane, carbon dioxide, and nitrogen dioxide are produced from the landfill, which contributes directly to global warming. Even the leachate system contributes to the addition of greenhouse gases.

The most serious form of water pollution from landfills is direct leachate contamination, considered a major environmental and human-health hazard. Leachate is a highly odorous black or brown liquid that commonly contains heavy metals, such a lead, and volatile organic compounds or VOCs.
