1. What is the primary purpose of a Phase I Environmental Site
Assessment (ESA)?
A) To conduct soil remediation
B) To remove contaminants from groundwater
C) To identify potential environmental liabilities and recognize
recognized environmental conditions
D) To monitor air quality
The Phase I ESA is a preliminary assessment to identify potential
contamination risks before property transactions.
, 2. Which regulatory agency enforces hazardous waste cleanup standards
in Texas?
A) Texas Commission on Environmental Quality (TCEQ)
B) Environmental Protection Agency (EPA) only
C) Occupational Safety and Health Administration (OSHA)
D) Texas Department of Health
TCEQ is the state agency responsible for environmental regulation
enforcement in Texas, including remediation standards.
3. Which of the following contaminants is most commonly associated
with petroleum spills?
A) Heavy metals
B) Polychlorinated biphenyls (PCBs)
C) Benzene
D) Asbestos
Benzene is a volatile organic compound frequently found in petroleum and
is a primary concern in petroleum spill sites.
4. What is the main goal of in situ bioremediation?
A) To physically remove contaminated soil
B) To pump and treat contaminated groundwater
C) To use chemical oxidation to destroy contaminants
D) To stimulate the natural breakdown of contaminants using
microorganisms within the soil or groundwater
,In situ bioremediation leverages microbes to degrade contaminants
without excavation or extraction.
5. What is the significance of a Record of Decision (ROD) in
environmental remediation?
A) It is the final cleanup plan approved by the responsible agency
B) It marks the completion of site remediation
C) It is a legal document that releases the responsible party from
liability
D) It documents the selected remedial action after evaluation of
cleanup alternatives
The ROD explains the chosen remediation method after review of all
options and public input.
6. What does the term “brownfield” refer to?
A) Land designated for agricultural use
B) An area with hazardous waste but no redevelopment plans
C) Previously developed land that may be contaminated but is
suitable for redevelopment
D) Land preserved as a natural habitat
Brownfields are sites with possible contamination but have potential for
reuse after cleanup.
7. What is the first step in an environmental remediation project?
A) Soil excavation
, B) Site monitoring
C) Site assessment and investigation
D) Waste disposal
Understanding the site conditions through assessment is crucial before any
cleanup begins.
8. Which of the following is NOT a common method for groundwater
remediation?
A) Pump and treat
B) Permeable reactive barriers
C) Soil vapor extraction
D) Thermal desorption
Thermal desorption is mainly used for soil remediation, not groundwater
cleanup.
9. What does Vapor Intrusion refer to?
A) The release of gases into the atmosphere
B) The migration of gases from contaminated soil or groundwater into
indoor air spaces
C) Injection of vapor-phase chemicals to treat contamination
D) None of the above
Vapor intrusion is a concern because volatile contaminants can enter
buildings and pose health risks.
