What is the purpose of targeted sampling in lead-based paint assessment?

Targeted sampling in lead-based paint assessment focuses specifically on identifying dwellings that are most likely to contain lead-based paint hazards. This approach is efficient and practical, as it allows assessors to concentrate their efforts and resources on units where the risk of lead exposure is higher, rather than randomly sampling across all units.

This targeted strategy is informed by factors such as the age of the buildings, previous inspections, and any history of lead-based paint use. By concentrating on higher-risk locations, assessors can prioritize their inspections and interventions, ultimately leading to more effective hazard mitigation.

In contrast, selecting all dwellings in a complex does not discriminate based on risk and would not be an efficient use of resources. Ensuring statistical representation might gather data across a wider range of conditions but doesn't necessarily target those most likely to pose lead hazards, and evaluating maintenance history, while potentially informative, does not directly address lead-based paint presence. Therefore, the objective of targeted sampling is to efficiently locate and assess those sensitive areas where lead exposure is most likely, enabling timely and effective action.
