1. What is the primary purpose of a solid waste facility operator?
A. To maximize the amount of waste accepted
B. To operate the facility safely and in compliance with applicable requirements
C. To eliminate all waste generation
D. To sell recyclable materials only
Answer: To operate the facility safely and in compliance with applicable
requirements
Rationale: The operator's central responsibility is to ensure safe, efficient, and
environmentally compliant facility operations.
2. Which material is generally considered municipal solid waste?
A. Household trash
B. Untreated radioactive waste
C. Explosives
D. Medical waste requiring specialized treatment
Answer: Household trash
,Rationale: Municipal solid waste commonly includes ordinary household and
community-generated discarded materials.
3. What is the first action an operator should take when an incoming load
appears to contain prohibited waste?
A. Mix it with other waste
B. Accept it and document it later
C. Stop the load from being improperly disposed of and follow the facility's
rejection procedures
D. Bury it immediately
Answer: Stop the load from being improperly disposed of and follow the
facility's rejection procedures
Rationale: Suspected prohibited waste must be handled according to
established acceptance, rejection, isolation, and notification procedures.
4. What is the main purpose of a landfill liner?
A. Increase vehicle speed
B. Reduce groundwater contamination
C. Increase landfill height
D. Prevent compaction
Answer: Reduce groundwater contamination
Rationale: Engineered liners help limit migration of contaminated liquids from
waste into underlying soil and groundwater.
5. What is leachate?
A. Clean stormwater
B. Liquid that has passed through or contacted waste and contains dissolved or
suspended contaminants
C. Landfill gas
D. Soil used for cover
,Answer: Liquid that has passed through or contacted waste and contains
dissolved or suspended contaminants
Rationale: Leachate is generated when water contacts waste and picks up
contaminants and other constituents.
6. Which factor can increase leachate generation?
A. Increased precipitation
B. Reduced waste moisture
C. Covered waste with no infiltration
D. Dry weather only
Answer: Increased precipitation
Rationale: Rain and other water sources can infiltrate waste and increase the
quantity of leachate produced.
7. Why is daily cover applied to active landfill areas?
A. To increase litter
B. To control odors, fires, vectors, and blowing debris
C. To prevent compaction
D. To eliminate the need for drainage
Answer: To control odors, fires, vectors, and blowing debris
Rationale: Cover is an important operational control for environmental,
nuisance, and safety concerns.
8. What is a common material used as landfill cover?
A. Clean soil or approved alternative daily cover
B. Hazardous waste
C. Untreated sewage
D. Liquid petroleum
Answer: Clean soil or approved alternative daily cover
, Rationale: Approved cover materials help isolate waste and control nuisance
conditions.
9. What is landfill compaction intended to accomplish?
A. Increase waste volume
B. Reduce waste volume and improve stability
C. Increase litter
D. Eliminate leachate
Answer: Reduce waste volume and improve stability
Rationale: Proper compaction conserves landfill airspace and improves the
stability of the waste mass.
10.Which piece of equipment is commonly used to compact waste?
A. Landfill compactor
B. Passenger sedan
C. Water heater
D. Forklift only
Answer: Landfill compactor
Rationale: Specialized landfill compactors are designed to densify waste and
support efficient landfill operations.
11.What is the purpose of a landfill gas collection system?
A. Collect and control gases generated by decomposing waste
B. Increase methane concentration inside buildings
C. Eliminate all oxygen from the landfill
D. Increase groundwater flow
Answer: Collect and control gases generated by decomposing waste
Rationale: Gas collection systems control landfill gas migration and may route
gas to beneficial-use or destruction systems.
