What is the primary purpose of the site characterization report?

• A. To publish the raw data only
• B. To provide a marketing summary
• C. To record only successful sampling events
• D. To document methods, data, interpretations, uncertainties, and recommended actions to support risk management and regulatory decisions

Answer: (C)

The key idea is that a site characterization report should be a complete, decision-focused record that shows how the site was investigated, what was found, how it was interpreted, what uncertainties remain, and what actions are recommended to manage risk and meet regulatory requirements. This makes the report a defensible basis for risk assessment and regulatory decisions, not just a collection of data or a marketing piece.

That’s why documenting methods, data, interpretations, uncertainties, and recommended actions is the best fit. It ensures readers understand how conclusions were reached, what limitations exist, and what steps should be taken next to reduce risk or meet regulatory expectations. Raw data alone isn’t enough because it doesn’t explain how the data were collected or interpreted; a marketing summary would be irrelevant to risk management; and recording only successful sampling events would omit important failed or inconclusive results that are essential for a true risk assessment.
