What type of sample is required for lead hazard screening aside from composite samples?

For lead hazard screening, entry wipe samples are a critical type of sample because they directly assess the presence of lead dust on surfaces that occupants frequently touch. These samples are gathered to evaluate the potential for lead exposure at entry points to a home or building, such as doorframes and windowsills, which are common areas for lead dust accumulation.

The results of entry wipe samples can provide actionable insights into lead levels in environments frequented by residents, particularly children, who are at higher risk for lead exposure. The analysis of these samples is essential in identifying risks and determining the need for remediation efforts.

While air, water, and soil samples are also important in assessing lead presence in various environments, they serve different purposes and may not be as directly indicative of the immediate risk of lead exposure within living spaces compared to entry wipe samples.
