1. The primary purpose of an Environmental Impact Assessment (EIA) is to:
A) Monitor employee safety
B) Evaluate the effects of a proposed project on the environment
C) Determine project profitability
D) Develop marketing strategies
B) Evaluate the effects of a proposed project on the environment
EIAs identify potential environmental consequences before projects begin,
ensuring sustainable development.
2. Which federal agency enforces the Clean Water Act?
A) USDA
B) EPA
C) OSHA
D) FEMA
B) EPA
The Environmental Protection Agency (EPA) regulates water pollution under the
Clean Water Act.
3. What is the main source of nitrogen oxides in urban areas?
A) Industrial solvents
B) Motor vehicles
C) Agricultural fertilizers
D) Natural gas leaks
,B) Motor vehicles
Vehicles emit nitrogen oxides (NOx) from fuel combustion, a key contributor to
urban smog.
4. Which method is most effective for removing particulate matter from
industrial emissions?
A) Activated carbon filters
B) Electrostatic precipitators
C) UV treatment
D) Chlorination
B) Electrostatic precipitators
These devices use electrical charges to remove fine particles from exhaust
streams.
5. What is the primary cause of acid rain?
A) Carbon dioxide
B) Sulfur dioxide and nitrogen oxides
C) Methane
D) Chlorofluorocarbons
B) Sulfur dioxide and nitrogen oxides
These gases react with water vapor in the atmosphere, forming acidic
precipitation.
6. A wetlands mitigation plan is designed to:
A) Eliminate all wetlands in a project area
B) Compensate for wetlands loss by creating or restoring wetlands
elsewhere
C) Increase urban development
D) Divert stormwater to sewers
B) Compensate for wetlands loss by creating or restoring wetlands elsewhere
Mitigation ensures no net loss of wetland function or area.
7. The Maximum Contaminant Level (MCL) under the Safe Drinking Water Act
refers to:
A) The minimum amount of treatment required
B) The highest allowable concentration of a contaminant in drinking water
, C) The average industrial discharge limit
D) The standard for wastewater effluent
B) The highest allowable concentration of a contaminant in drinking water
MCLs protect public health by limiting harmful substances in drinking water.
8. Which is considered a non-point source of water pollution?
A) Wastewater treatment plant
B) Agricultural runoff
C) Industrial effluent pipe
D) Landfill leachate discharge
B) Agricultural runoff
Non-point sources are diffuse and not discharged from a single identifiable
location.
9. What is the primary purpose of a Superfund site cleanup?
A) Promote industrial growth
B) Clean up hazardous waste contamination
C) Increase recreational areas
D) Build new infrastructure
B) Clean up hazardous waste contamination
Superfund sites are managed to reduce risk to human health and the environment.
10. Biochemical Oxygen Demand (BOD) measures:
A) The pH of water
B) The amount of dissolved oxygen required by microorganisms to
decompose organic matter
C) Heavy metal content
D) Water turbidity
B) The amount of dissolved oxygen required by microorganisms to decompose
organic matter
BOD indicates the level of organic pollution in water bodies.
11. Which type of soil is most susceptible to leaching of contaminants?
A) Clay
B) Sand
