Which of the following represents a composite dust wipe sample requirement?

At least two samples from floor, window, and bare soil
One sample from every room
Only exterior samples
Monthly sampling

The correct answer is: At least two samples from floor, window, and bare soil

The requirement for composite dust wipe sampling involves collecting multiple samples to ensure a comprehensive assessment of lead contamination in residential environments. By taking at least two samples from the floor, window sills, and bare soil, the sampling process captures variations in lead dust levels that may occur across different locations within a property. This approach complies with guidelines designed to ensure that the assessment reflects the overall condition of lead contamination in various critical areas of a home where children might be exposed to lead dust. In contrast, collecting only one sample from every room does not adequately account for the different lead dust levels that may exist in each area, potentially overlooking high-risk locations. Similarly, focusing exclusively on exterior samples does not provide a complete picture of exposure risks that individuals, especially children, may face indoors. Monthly sampling does not align with the typical requirements for composite dust wipe sampling as frequency and sampling methodology are guided by specific regulations and the presence of lead hazards.
