How many subsamples does the EPA recommend for each composite sample?

1 to 2
2 to 4
3 to 10
10 to 15

The correct answer is: 3 to 10

The EPA recommends collecting a specific number of subsamples for each composite sample to ensure statistically valid results when assessing lead-based paint hazards. The recommended range is three to ten subsamples. This approach allows for a more accurate representation of the lead levels within the area being tested, considering potential variability in lead concentration. By obtaining multiple subsamples, risk assessors can account for inconsistencies and ensure that their findings reflect the true risk associated with lead exposure more comprehensively. Collecting fewer subsamples may not provide an adequate assessment, while collecting an excessive number may be unnecessary and inefficient. This methodology is crucial in regulatory assessments, where reliable data is essential for safeguarding public health and creating effective remediation strategies.
