A colormetric spot test can usually indicate the presence of lead in a chip of peeling paint, and its lead content can be determined at low cost through laboratory analysis. For example, clearance tests performed after activities that disturb or repair lead paint provide a low-cost check to ensure that lead dust hazards are not left behind. 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.
