A. Clean Air Act
B. Resource Conservation and Recovery Act (RCRA) Subtitle D
C. Safe Drinking Water Act

2. The primary purpose of daily cover at a landfill is to:
A. Increase landfill gas production
B. Prevent odors, pests, and litter
,C. Improve waste decomposition rate
D. Increase compaction efficiency
Answer: B. Prevent odors, pests, and litter

windblown litter while improving site sanitation.
3. Which material is most commonly used as daily landfill cover?
A. Sand
B. Clay soil
C. Gravel
D. Concrete
Answer: B. Clay soil
Clay soil is commonly used because it provides good compaction and acts as a

groundwater contamination.
5. The main function of a landfill liner is to:
A. Promote decomposition
B. Support heavy equipment
C. Prevent leachate migration into soil and groundwater
