The HUD Lead-Based Paint Hazard Control Grant Program is being evaluated through a multi-year study involving 14 grantees in eleven states across the country. The intervention strategies implemented by the grantees range from simple removal of lead-based paint followed by extensive cleaning to extensive renovation including window replacement. The objectives of this analysis included the determination of the net reaccumulation rates at one and two years post-intervention and an estimation of the hazard control factors and pre- and post-intervention conditions on changes in dust lead loadings. Floor and interior entry dust lead loadings at one and two years post-intervention were the same as or slightly below those immediately post-intervention. Window sill and trough lead levels at one and two years post-intervention were moderately higher than those immediately post-intervention but still well below the pre-intervention levels. Sill levels were less than 20% of clearance levels and trough levels were between 50 and 70% of clearance levels. Window sill lead reaccumulation rates at one and two years post-intervention were affected by interior paint lead level pre-intervention and post-intervention deterioration of exterior elements of the housing. Window trough dust lead reaccumulation was affected at both one and two years post-intervention by Grantee and interior condition of lead paint; at one year post-intervention additional factors such as lead hazard control costs, paint lead levels and number of treatment failures were also involved.
Learning Objectives: (1) Recognize that dust lead reaccumulation rates are different for floors, window sills and window troughs; (2) Identify pre- and post-intervention factors that affect the rate of reaccumulation of lead dust in housing; (3) Define units of measurement of dust lead reaccumulation
