A. To build new structures
B. To restore contaminated sites to safe conditions
C. To increase property value
D. To expand industrial operations
B. To restore contaminated sites to safe conditions
Rationale: Environmental remediation focuses on cleaning up
polluted sites to protect human health and the environment.
2. Which federal law governs hazardous waste management in the United
States?
A. Clean Air Act
B. Resource Conservation and Recovery Act (RCRA)
C. Clean Water Act
D. National Environmental Policy Act
B. Resource Conservation and Recovery Act (RCRA)
Rationale: RCRA establishes the framework for proper management
of hazardous and non-hazardous waste.
3. What type of contamination is typically addressed by soil vapor
extraction?
A. Heavy metals
B. Volatile organic compounds (VOCs)
, C. Asbestos fibers
D. Biological pathogens
B. Volatile organic compounds (VOCs)
Rationale: Soil vapor extraction is effective for removing VOCs from
unsaturated soil.
4. What is the purpose of a site assessment in environmental remediation?
A. To prepare construction plans
B. To evaluate contamination levels and potential risks
C. To design landscaping
D. To increase property value
B. To evaluate contamination levels and potential risks
Rationale: Site assessments identify contaminants, their extent, and
the associated risks to guide remediation planning.
5. Which of the following is considered a hazardous waste?
A. Food scraps
B. Paint containing lead
C. Yard trimmings
D. Clean sand
B. Paint containing lead
Rationale: Lead-based paint is hazardous due to its toxicity and

7. Which method is commonly used to remediate groundwater
contaminated with petroleum hydrocarbons?
A. Excavation and disposal
B. Air sparging
C. Thermal desorption
D. Soil compaction
, B. Air sparging
Rationale: Air sparging introduces air into groundwater to volatilize
and remove petroleum hydrocarbons.

A. To prevent contamination spread
B. To improve aesthetics
C. To increase soil fertility
D. To enhance groundwater recharge
A. To prevent contamination spread
Rationale: Containment barriers, such as slurry walls or caps, isolate
contaminants to prevent migration.
9. What is the primary hazard of asbestos exposure?
A. Skin irritation
B. Lung diseases, including mesothelioma and asbestosis
C. Eye infection
D. Liver failure
B. Lung diseases, including mesothelioma and asbestosis
Rationale: Inhalation of asbestos fibers can cause severe respiratory
illnesses and cancers.
10. Which of the following is a common technique for remediating
lead-contaminated soil?
A. Phytoremediation
B. Soil washing
C. Air sparging
D. Carbon filtration
B. Soil washing
Rationale: Soil washing separates lead particles from soil, reducing
contamination.
11. Which regulatory agency oversees underground storage tank
(UST) remediation in Georgia?
A. EPA and Georgia Environmental Protection Division (EPD)
B. OSHA
C. FEMA
D. Department of Transportation
A. EPA and Georgia Environmental Protection Division (EPD)
