Questions & Answers

Q: What are landfills used for?

Landfills are used to dispose of non-biodegradable waste materials that do not decompose or rot, preventing pollution of the air, groundwater, and surrounding environment.

Q: How do landfills prevent pollution?

Landfills are designed with bottom liners and covers to prevent waste materials from coming in contact with the groundwater and air, thus preventing pollution of these resources.

Q: Are landfills constructed below or on top of the ground?

Landfills can be constructed both below and on top of the ground. Below-ground landfills resemble bathtubs, with bottom liners and covers, while on-top landfills resemble mountains with layers of soil covering the waste materials.

Q: What happens to landfills after they are covered?

After being covered, landfills are left undisturbed for several years, allowing more layers of soil to accumulate over the waste materials, further isolating them.

Summary & Key Takeaways

• Landfills are designed to dispose of non-biodegradable waste, preventing pollution of air, groundwater, and surrounding environment.

• Non-biodegradable waste materials do not decompose or rot, so proper disposal is crucial to prevent pollution.

• Landfills can be constructed below or on top of the ground, isolating the waste materials from the environment.
