What are the effects of landfill?

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.
