Re: 120 Broadway- Bulk Sample Analysis Results- Lobby Floor Surface- Dust
Material
Dear Mr. Dacunto:
On September 13, 2001 Advanced Environmental Corp (AEC) collected and analyzed
eleven (11) bulk samples of the dust material located throughout the lobby of 120
Broadway. This dust was created by the World Trade Center collapse.
The purpose of this analysis was to determine if this dust material contained asbestos.
The samples were analyzed by the EPA recommended Polarized Light Microscopy
with Dispersion Staining method (PLM/DS).
The samples were analyzed by EMSL Analytical ( NYS ELAP # 11506).
Please be advised that via PLM/DS, all of the samples either proved negative for
asbestos content or proved to contain less than 1% asbestos. New York City and
State consider asbestos containing material to be "any material containing more
than 1% asbestos". Thus this material is considered to be non-asbestos
containing.
Attached are the laboratory analysis data sheets.
Should yo}u have any further questions please call me at (212) 545-1855.
