How does the inspector choose soil sampling locations?

• A. Sampling locations are based on the hazard control strategy used and their professional judgement.
• B. Randomly across the site
• C. Only at the corners of the site
• D. Based on owner preference

Answer: (A)

Choosing soil sampling locations starts with a risk-based approach. The inspector plans the sampling to align with the hazard control strategy being used and relies on professional judgment to target areas most likely to show elevated lead in soil and to verify that the controls are working. This means sampling is focused where exposure risk is highest or where remediation will have the most impact, rather than sampling at random points or in a fixed pattern. Think about where children play, where soil can be disturbed or tracked indoors, and where lead-based paint is present on exterior surfaces or near the foundation. These factors guide which spots to sample so the data accurately reflect actual risk and help determine if the chosen controls are effective. Sampling only at corners or based on owner preference would not reliably capture hotspots or the true level of risk.
