CONCLUSIONS:
An air quality monitoring project was conducted in the inside the townhouses
located at 51 Harrison Street, New York, NY. The scope of work at the
townhouses was the air quality testing in tow different areas of the house chosen
randomly as per our professional judgment. The samples were collected during
regular activities.
The air testing was conducted in response to an emergency situation that
aroused due to the tragic events that happened in the financial district of
Manhattan on September 11, 2001. The tests were conducted to determine the
concentration of airborne asbestos fibers in the areas. The air monitoring and
inspection was conducted on November 6, 7 2001.
The project was conducted following all the NYC Department of Environmental
Protection (Title 15), NYS Department of Labor (Industrial Code 56) and all EPA
Federal applicable regulations.
The results found in each of the areas of the different buildings were below the 70
structures/mm2 standard number established by the Environmental Protection
Agency (EPA), New York City Department of Environmental Protection
(NYCDEP), New York State Department of Labor (NYSDOL), New York City
Department of Health (NYCDOH) and the Occupational Safety and Health
Administration (OSHA).
A visual inspection was also conducted in different areas of the buildings such as
roofs, hallways, garages, compactor rooms, common areas, etc., to identify any
or all suspicious materials. It was not necessary at the time to collect any bulk
sample since there was no suspicious materials found in the premises.
