In the National Survey of Lead-Based Paint in Housing, conducted by EPA and HUD, lead measurements were collected on exterior soil, interior house dust, and in interior and exterior paint for each sampled dwelling unit. In addition, the dwelling unit's age, Census region, and degree of urbanization were obtained. This report presents findings from the National Survey on the prevalence and concentrations of lead in soil in private and public housing units in the United States. These findings include national estimates of the number of private housing units with various soil lead concentrations and average soil lead concentrations by building age, Census region, and degree of urbanization. The report also summarizes the statistical associations between soil lead concentrations and building age, degree of urbanization, Census region, and the presence and condition of lead-based paint. An analysis of covariance model was used to identify possible predictors of lead in soil. The age of the dwelling unit was the predominate predictor of soil lead. Other statistically significant predictors of soil lead included the dwelling unit's Census region, the dwelling units' average lead paint levels, and local automobile emissions.
