What is the purpose of worst case sampling?

Worst case sampling is a methodology used primarily to assess the potential lead hazards in a dwelling by examining scenarios that present the greatest risk. The aim is to identify the highest-risk dwellings where lead hazards may be present in significant amounts. By focusing on the worst-case scenarios, lead assessors can more effectively evaluate the potential health risks associated with lead exposure, particularly for vulnerable populations such as children.

This approach allows for comprehensive risk assessment because it does not merely consider typical conditions but rather anticipates the most hazardous situations. Such an assessment can then guide remediation efforts and prioritize interventions in dwellings where the risk of lead exposure is most acute. Overall, the process ensures that the necessary actions are taken in the most critical situations to protect occupants from lead-related health issues.
