Today the most widespread source of lead exposure in the environment of U.S. children is lead-based paint that was applied to residential buildings before 1978. Exposure to lead in paint can come from the paint chips themselves, from dust caused by abrasion on friction surfaces, or from chalking of exterior paint. A study was conducted to demonstrate the effectiveness of a wet abrasive blasting technology to remove lead-based paint from exterior wood siding and brick substrates, and the effectiveness of two Best Demonstrated Available Technologies (BDAT) to stabilize the resultant blasting media (coal slag and mineral sand) paint debris to reduce the leachable lead content. The average lead loading of the paint coating on the wood and brick substrates was 6.9 and 51.9 mg/sq. cm., respectively. The effectiveness of the lead-based paint removal technology was determined using an X-ray fluorescence (XRF) spectrum analyzer (L&K shell). The XRF measurements were corroborated by analysis of substrate samples using inductively-coupled plasma atomic emission spectroscopy (ICP-AES). The effectiveness of the technologies to stabilize the debris was evaluated through the Toxicity Characteristic Leaching Procedure (TCLP).
