1. Which statement most accurately describes the fundamental objective
of pollution prevention (P2) in an environmental protection program?
A. To treat pollutants after they have entered the environment
B. To dispose of hazardous waste in a manner that minimizes regulatory
liability
C. To reduce, eliminate, or prevent pollution at its source before it is
generated
D. To transfer pollutants from one environmental medium to another
Answer: C.
Rationale: Pollution prevention is fundamentally a source-reduction
strategy that seeks to prevent pollution before it is created. It is generally
preferable to recycling, treatment, or disposal because it can reduce
environmental impacts as well as waste-management costs.
2. A manufacturing facility is evaluating four proposed environmental
improvement measures. Which measure represents the highest level
, of pollution prevention according to the waste-management
hierarchy?
A. Installing an incinerator to destroy hazardous waste
B. Recycling solvent after it has been discarded
C. Treating contaminated wastewater before discharge
D. Modifying the production process so that the solvent is no longer
required
Answer: D.
Rationale: Eliminating the need for a hazardous material through process
modification prevents the waste from being generated in the first place.
Source reduction is therefore more preferable than recycling, treatment, or
disposal.
3. An environmental manager discovers that a facility generates
excessive quantities of cleaning solvent waste. Which initial action
would most closely reflect pollution-prevention principles?
A. Increase the frequency of hazardous-waste collection
B. Determine why the solvent is being used and evaluate less hazardous
alternatives
C. Construct a larger hazardous-waste storage area
D. Increase the concentration of solvent before disposal
Answer: B.
Rationale: Effective pollution prevention begins by examining the process
that generates the waste and identifying opportunities to eliminate or
reduce the material at its source. Substitution with a less hazardous
chemical can reduce both waste generation and environmental risk.
4. Which of the following is the best example of source reduction rather
than recycling?
,A. Recovering copper from discarded electronic equipment
B. Reusing treated wastewater in a cooling system
C. Redesigning a product so that less raw material is required during
manufacture
D. Sending used paper to a recycling facility
Answer: C.
Rationale: Source reduction occurs before waste is generated and includes
changes in product design, materials, or processes that reduce the amount
or toxicity of waste produced. Recycling manages materials after they
have become waste.
5. A facility replaces a highly toxic degreasing chemical with a less toxic
biodegradable cleaning agent that performs the same function. Which
pollution-prevention approach is being applied?
A. Chemical substitution
B. End-of-pipe treatment
C. Environmental remediation
D. Waste dilution
Answer: A.
Rationale: Chemical substitution involves replacing a hazardous or
environmentally harmful substance with a safer alternative while
maintaining the required process function. It is a recognized source-
reduction strategy.
6. Which environmental management strategy generally provides the
greatest opportunity to reduce both waste-management costs and
environmental impacts?
A. Preventing waste generation at the source
B. Increasing landfill capacity
C. Increasing wastewater-treatment capacity
D. Increasing the frequency of environmental sampling
, Answer: A.
Rationale: Preventing pollution at its source reduces the quantity of
material that must subsequently be collected, transported, treated,
recycled, or disposed of. This can reduce both environmental and financial
costs.
7. During a pollution-prevention assessment, an auditor observes that a
production line frequently discards partially used raw materials
because batches are improperly prepared. Which corrective action is
most appropriate?
A. Construct a larger waste-storage area
B. Improve process control and operator procedures to prevent batch errors
C. Increase waste transportation frequency
D. Dilute the discarded material before treatment
Answer: B.
Rationale: Improving process control prevents raw materials from
becoming waste and therefore addresses the problem at its source. It is
preferable to managing the improperly produced material after it becomes
waste.
8. Which of the following is the strongest indicator that a proposed
environmental project is truly a pollution-prevention project?
A. It moves waste from air emissions to wastewater
B. It increases the efficiency of a treatment plant
C. It eliminates or reduces the generation of pollutants before they require
treatment
D. It increases the amount of waste sent to a licensed disposal facility
Answer: C.
Rationale: Pollution prevention focuses on avoiding or reducing pollutant
generation before treatment or disposal becomes necessary. Merely
