In response to requirements mandated by the Lead-Based Paint Poisoning Prevention Act, in 1989 the U.S. Department of Housing and Urban Development (HUD) initiated the Lead-Based Paint Abatement Demonstration Study in seven urban areas across the U.S. The objectives of this study were to assess the cost, worker hazards, and short-term efficacy of various lead-based paint abatement methods. Among other conclusions, the FHA portion of this study estimated that abatement costs for a single-family dwelling could range from $2000 to 12,000. One question which was not answered by the HUD Abatement Demonstration was that of the long-term efficacy of the abatement methods. Therefore, in 1990 the U.S. Environmental Protection Agency (EPA), in cooperation with HUD, initiated the Comprehensive Abatement Performance (CAP) Study to address this question. The CAP Study was a follow-up to HUD Abatement Demonstration activities performed in Denver, Colorado. There were four primary objectives of the CAP Study: (1) assess the long-term efficacy of two primary abatement methods, (2) characterize lead levels in household dust and exterior soil in unabated homes and homes abated by different abatement methods, (3) investigate the relationship between lead in household dust and lead from other sources, in particular, exterior soil and air ducts, and (4) compare dust lead loading results from cyclone vacuum sampling and wipe sampling protocols. To address these objectives, the CAP Study collected approximately 30 dust and soil samples at each of 52 HUD Demonstration houses in Denver, approximately two years after the abatements had been completed. The houses were all occupied at the time of the CAP study field sampling, though they had not been continuously occupied between the completion of the abatements and the field sampling. The samples were analyzed for their lead content, and these lead measurements were then used in detailed statistical analyses addressing the four study questions. This report documents the results of the CAP Study.
