d) Noise pollution
RCRA governs the generation, transportation, treatment, storage, and
disposal of hazardous waste.
4. What is the main function of a landfill liner?
a) To keep trash in place
, b) To prevent leachate from contaminating groundwater
c) To separate recyclable materials
d) To absorb odors
Landfill liners are designed to protect groundwater by preventing leachate
migration.
5. What does “leachate” refer to in waste management?
a) Rainwater collected on site
b) Liquid that drains or ‘leaches’ from a landfill
c) Chemical used to treat waste
d) Runoff from compost piles
