What is a dust wipe sample primarily used for?

A dust wipe sample is primarily used to collect and analyze surface dust for lead levels. This method involves taking a sample from surfaces within a building, such as floors, windowsills, and other areas where dust accumulation is likely. The collected sample is then analyzed to determine the concentration of lead, which is crucial for assessing potential lead exposure risks, particularly in environments where children or pregnant women are present.

This type of sampling is particularly important in residential settings that may have lead-based paints or plumbing, as it helps identify whether lead dust is present at levels that could pose health risks. By establishing the presence and concentration of lead in surface dust, lead inspectors and risk assessors can make informed decisions regarding remediation and safety measures.

The other choices do not accurately reflect the primary use of dust wipe samples: soil samples focus on the composition of the ground, air quality analysis pertains to airborne contaminants, and testing drinking water examines the quality of water sources rather than surface dust.
