EPA Region 2 hires an industrial hygienist to test the lobby of its building at 290 Broadway St. for the presence of asbestos. The building is located 6 blocks northeast of the World Trade Center site. Some of the settled dust samples collected with a micro-vac and analyzed using transmission electron microscopy (TEM) reveal the presence of chrysotile asbestos. Light microscope tests are also used to analyze the dust, but these tests turn up negative. [Jenkins, 3/11/2002 pdf file; Kupferman, 2003 pdf file; Jenkins, 7/4/2003 pdf file] Air monitoring also reveals the presence of asbestos:

[Jenkins, 3/11/2002 pdf file; Kupferman, 2003 pdf file; Jenkins, 7/4/2003 pdf file] The EPA later states that micro-vac collection of dust samples (one of the preferred methods of obtaining samples) and TEM testing are not necessary for schools and residences in Lower Manhattan. At 105 Duane Street, the EPA will even discount results obtained by micro-vac collection and TEM tests when they contradict the agency’s own results (see December 3, 2001).

The FBI’s letter to Bruce Ivins.The FBI’s letter to Bruce Ivins. [Source: FBI] (click image to enlarge)Bruce Ivins is sent a formal letter by prosecutors saying that he is “not a target” of the FBI’s anthrax attacks investigation. In fact, samples of the anthrax used in the attacks have been shown to match anthrax once controlled by Ivins (see Early 2007) and Ivins has already been questioned about late-night work he had conducted in the USAMRIID laboratory shortly before the anthrax letters were mailed (see March 31, 2005). [New York Times, 9/6/2008] Since late 2006, Ivins has correctly been under the impression that he is a target of the investigation (see Late 2006).
