The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere
A landfill is composed of 4 essential components and some are ;
- bottom linear
- hydrogeologic component and
- A cover ( seal )
Given that a landfill constitutes of about 40 to 60 percent of C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂ into the atmosphere. while
The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.
Hence we can conclude that Landfills can produce carbon dioxide that leak into the atmosphere.
