• C. Waste is buried in-between layers of soil and is compacted nicely to make it a hard surface
• D. Both $A$ and $B$

Answer 1

Answer: (A), (B), (C)

A sanitary landfill is a low-lying area that is filled with waste rejects
It has a liner at the bottom to prevent the groundwater from contaminating with the mix of the liquid that oozes from the waste that is buried called the leachate
Waste is buried in-between layers of soil and is compacted nicely to make it a hard surface

Sanitary landfills are sites where waste is isolated from the environment until it is safe. It is considered when waste has completely degraded biologically, chemically and physically.

It has a liner at the bottom to prevent the groundwater from contaminating with the mix of the liquid that oozes from the waste that is buried called the leachate (water that has percolated through a solid and leached out some of the constituents).

Landfills comprise the compacted waste and soil covering for each day.
