the more sensitive method by HP Environmental showed 7 of 11 samples had hazardous levels.
The complete study was posted on the American Industrial Hygiene Assodation (AIHA) wd)site for a total of 5 hours on 9/3/01 before it was removed. The AIHA has not admitted its removal was motivated by the fact that it conflicted with Governor Whitman’s press release of the same day claiming no hazardous exposures to asbestos except at Ground Zero.
HP Environmental is in Herndon, VA, Dr. Granger, lead investigator. It also performed the asbestos studies when the Trade Towers were bombed in 1993, and many other asbestos studies for the government. The complete study will soon be posted at www.nycosh.org/linktopics/WTC-catastrophe.html,www.nyenvirolaw.org and other sites.

10/12/01 - Ground Zero Elected Officials Task Force commissioned study shows hazardous asbestos levels in apartments
The Ground Zero Elected Officials Task Force includes U.S. Congress members, NY State Assembly and Senate members, and New York City Council members and other ofiScials representing citizens affected by the Trade Tower collapse. They commissioned a study by Chatfield Technical Consulting Ltd. and Environmental Quality Management, Inc. (Posted at www.nycosh.org/linktopics/WTC-catastrophe.html )
The air inside and surface dusts in and around two apartment buildings were tested. A “low exposure building” (45 Warren St.) was 4 blocks from the World Trade Center had all the windows intact. A dust layer was present inside the closed apartments, even though the windows had been closed. A “high exposure” building close to Ground Zero (250 South End Ave) had several windows broken by die blast. The following are some of the results, along with the concentrations that EPA found in surface dust and airnear these two buildings:
LOW EXPOSURE BUILDING ASBESTOS LEVELS: highest inside airborne asbestos - 316 structures/square mm dust on roof outside building -1,05% EPA dust level, Warren & W, Bdwy - none detected EPA dust level. Chambers & W. Bdwy - none detected EPA air levels. Church & Duane, none detected to 59.4 structures/sq. mm.
HIGH EXPOSURE BUILDING ASBESTOS LEVELS: highest inside airborne asbestos - 10620 structures/sq. mtn dust, exterior window ledge - 2.25% dust, ground level courtyaid, top of wall - 2.05% EPA dust level, Albany & West - 3% EPA dust level, 225 Rector -1.3% EPA air levels, Albany & West - none detected to 298.3 structures/sq. mm
