Where should dust samples be taken after a renovation project?

Taking dust samples after a renovation project is crucial to assess whether lead-based materials were disturbed and to maintain safety. The recommended practice involves comprehensive sampling to ensure that any lead dust contamination resulting from the renovation is accurately identified.

Sampling from multiple areas is essential because lead dust can migrate from the initial work site and settle in different locations throughout the property. Collecting samples from typical surfaces like a window sill, window well, and floor provides a thorough representation of lead dust exposure risks. Additionally, collecting a blank wipe serves as a control to determine any potential contamination from the sampling process itself. This multi-sampling approach allows for a more reliable assessment of the post-renovation environment.

In contrast, focusing on limited areas such as only the basement, solely the window sill, or just the outside of the house fails to capture the full extent of potential lead contamination in the home, which could lead to unsafe conditions going unnoticed. This comprehensive strategy of sampling ensures better health protection and compliance with safety standards.
