In addition, dust sampling can be used to screen high-risk housing to document lead dust hazards and set priorities for more intensive evaluations and hazard control measures. Collecting lead samples poses little risk, unlike asbestos and some other hazards. Nationwide, approximately 140 laboratories are accredited and recognized by EPA to analyze lead in dust, soil, paint chips, and other environmental media. Some laboratories offer even lower prices for bulk orders. In addition, some laboratories have pledged free analysis of lead samples to the Alliance for use by community-based nonprofit organizations.
Recent changes reduce barriers to entry to members of impacted communities.
Until recently, only state-certified lead inspectors and risk assessors performed lead dust sampling, which typically was used only after abatement projects. The extensive education and experience prerequisites and training requirements for lead inspectors and risk assessors have created significant barriers to entry to these disciplines for community residents and small contractors. Recognizing that visual inspections and clearance dust testing are simple and straightforward, EPA and HUD recently developed a one-day sampling technician training course to teach relevant information about how to visually inspect for deteriorated paint and collect lead dust samples. HUD s regulation imposing lead-safety requirements on federally assisted housing recognizes the important role of sampling technicians in providing clearance testing after all paint repair and rehab work in older properties. In contrast to the risk assessor and lead inspector disciplines, sampling technician training is readily accessible to staff and representatives of community-based organizations.
