  2. Leachate collection and treatment

  3. Gas collection and flaring

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are common methods of landfill closure. Capping involves placing a layer of impermeable material over the landfill to prevent the infiltration of water. Leachate collection and treatment involves collecting and treating the liquid that seeps from the landfill. Gas collection and flaring involves collecting and burning the methane gas that is produced by the decomposition of organic waste in the landfill.
