Which is the first step in the DoD Exposure Assessment Model?

• A. Define Scope
• B. Collect Data
• C. Analyze Exposure
• D. Report Findings

Answer: (A)

Defining the scope sets the direction for the entire assessment. It involves clarifying the purpose, which populations and exposures will be considered, the setting and time frame, the contaminants of interest, and the decision criteria that will guide conclusions. With these boundaries and objectives clear, you can determine what data are needed, what level of detail is appropriate, and how success will be measured. This upfront scoping prevents chasing irrelevant data, ensures critical exposure pathways are included, and aligns the rest of the process with the stakeholders’ needs. After defining the scope, you would collect data, analyze the exposure, and then report the findings.
