Re: Asbestos Testing Page 2 of 4
The .199 Chambers Street complex is currently being used to house various members of the rescue and recovery operation. There is concern that these personnel are carrying asbestos and lead contamination on their clothing when they return to the building. H. A. Bader Consultants scope of work was to dctcrminc if thcrc is a potential asbestos and/or lead related health conrrrn in the building.
The primary pathway for asbestos and lead to enter the building is through the ventilation systems and the main building entrances . There are approximately 30 air handling units (AHU) that have outdoor air capabilities. H. A. Bader Consultants performed asbestos testing in or near the outdoor air entry of every AHU. Asbestos and lead testing was performed at or near every building entrance, including those used by the rescue and recovery personnel. Concentrated sampling was performed in areas that are housing rescue and recovery operations. Samples were also taken in non occupied areas to evaluate ambient conditions.
Once asbestos fibers enter a building they may remain airborne or settle onto fixed surfaces (primarily horizozilal suifaces). Lead dust is heavy and settles very quickly. H. A. Bader Consultants testing methods concentrated on both airborne and surface testing for asbestos and only surface testing for lead.
Lead Testing
The U.S. Federal Department of Housing and Urban Development (HUD) and the City of New York Department of Environmental Protection (DEP) have established allowable levels of lead dust in residential scttings occupied by children. The HUD/DEP clearance level is of 50 µg/ft2. These levels are extremely conservative and apply to buildings where small children (less than six years old) reside or frequently visit.
23 lead dust samples were taken. 21 samples were below the level of detection. Two samples from the gymnasium bleachers had detectable lead levels (32 and 42 µg/ft), however they were within the HUD/DEP guideline levels. Reference the attached laboratory results from EMSL Analytical. The bleachers are used by the rescue and recovery personnel and there is a significant amount of dust and debris present. This testing indicates that significant lead contamination is not present in the building.
