Q. A sanitary landfill is provided with High Density Poly Ethylene (HDPE) lining along the ground surface. This is provided primarily to prevent

(A) Bleaching

(B) Leaching

(C) Rodents

(D) Plant growth

Explanation:

Geomembranes, predominantly high-density polyethylene (HDPE), have been used as bottom liners in landfills for almost 30 years for its resistance to chemical and corrosive. They minimize the transfer of leachate from the landfill to the environment. Leachate is the liquid that drains or ‘leaches’ from a landfill. It varies widely in composition regarding the age of the landfill and the type of waste that it contains. It usually contains both dissolved and suspended material.
