The study compared the relative effectiveness after six years of the different classes of interventions used by the HUD Lead Hazard Control grantees, after controlling for such factors as housing conditions and characteristics and resident and neighborhood characteristics.
Geometric mean dust-lead levels on floors and windowsills were 11% and 23% lower, respectively, at six years post-intervention than at any preceding point following the intervention. Although geometric mean window trough dust-lead levels were slightly higher at six years post-intervention than at other post-intervention time periods, they were still over 75% lower than before intervention.
More intensive treatments were associated with lower windowsill and window trough dust-lead levels, and significant differences in window sill and window trough dust-lead levels between treatment levels were evident. Findings from the Six-Year Extension Study indicate that across all grantees and treatment strategies the treatments applied were effective at significantly reducing environmental lead levels on floors, windowsills, and window troughs at least six years following the intervention.
