Re: Air Sample Results:
17 Battery Street
New York, NY
Dear Mr. Budabin:
Following the collapse of the World Trade Centers and associated properties, EMS was retained
by your office to perform baseline sampling within the building to determine if airborne asbestos
was present.
On September 25, 2001 EMS tested representative floors and subjected the samples to analysis
via Transmission Electron Microscopy (TEM). TEM analysis is deemed state of the art and is
able to distinguish between asbestos and non-asbestos fibers. It is important to note that during
the testing, the building HVAC was not operating and had not been operating prior to our testing.
Therefore, any debris within the system or building would likely have settled and not remain
airborne. Upon turning on the system, the results could be considerably different and may
warrant additional sampling.
The results that were obtained indicated that at the time of testing no asbestos was detected.
Current acceptable levels as set forth by the Environmental protection Agency are set at 70
slmm2. The standard of 70 s/mm2 is used to determine whether background levels or airborne
levels following an abatement project are acceptable for human occupancy. If the concentration
exceed 70 s/mm2, then additional testing along with clean-up and possible protective equipment
should be initiated.
Overall, based upon the sampling results, the air quality in regards to asbestos, according to EPA
standards, is acceptable. Once again, since testing was not performed under "normal"
conditions, the airborne concentrations could change once the building returns to normal
operation and air movement along with building activities resume.
If you have any questions or require additional information, please contact me.
Sincerely,
((
