A community has received a risk estimate for contamination near an industrial site. Officials now compare cleanup options while weighing scientific evidence, feasibility, costs, and community priorities. What process are they undertaking?
- A
Hazard identification, because it determines whether any response is needed
- B
Exposure assessment, because it estimates who contacts the contaminant
- C
Risk characterization, because it reports the magnitude of risk
- D
Risk management, because it selects actions using evidence and practical considerations
