What is a key consequence of insufficient surface area coverage during wipe sampling?

Explanation:
Insufficient surface area coverage hits the core idea of sample representativeness. Lead dust on surfaces isn’t spread evenly; it tends to cluster in hotspots and cleaner patches. If you don’t wipe a large enough area or you miss those dirty spots, the material you collect won’t reflect the surface’s true contamination. That bias typically shows up as an underestimation of lead content because the sample misses the higher-dust areas. Following a proper, systematic coverage plan helps ensure the wipe sample represents the surface as a whole.
