What substances is EPA testing for at the WTC and Pentagon?
EPA is monitoring for asbestos and particulates (dust) and other contaminants
typically found in large building fire and collapse situations.
What has EPA's testing shown so far?
EPA's air monitoring near the WTC has not detected any pollutants from the fire
and building collapses that are of concern to the general public. Within the
restricted zone (within one block of the WTC), EPA is finding low levels of asbestos
in the dust from the building collapse. At the Pentagon, EPA monitoring has found
either no asbestos or levels well below the level of concern. For more information

What is being done to control the dust in the WTC restricted area and protect
the rescue and cleanup workers?
EPA and OSHA are advising rescue and cleanup workers on dust control
measures, such as wetting down the debris to keep dust from getting into the air.
EPA also is operating 10 high efficiency vacuum trucks to remove dust in
residential and business areas near the WTC . EPA has advised the workers in the
restricted area to wear respirators to protect themselves from the dust and any
asbestos it may contain. For more information on dust and debris click here:
