The EPA publishes a summary of results from the air-monitoring program it implemented shortly after the 9/11 attacks. The summary covers the period between September 11 and September 30.
bullet “Out of a total of 442 air samples EPA has taken at Ground Zero and in the immediate area, only 27 had levels of asbestos above the standard EPA uses to determine if children can re-enter a school after asbestos has been removed—a stringent standard based upon assumptions of long term exposure. OSHA has analyzed 67 air samples from the same area, and all were below the OSHA workplace standard for asbestos.”
bullet “All fifty-four air samples from EPA’s four monitors in New Jersey found no [asbestos] levels above EPA’s standard. Another 162 samples were taken from EPA’s monitors at the Fresh Kills landfill in Staten Island, where debris from the World Trade Center is being taken; only two exceeded EPA’s standard.”
bullet “Of 177 bulk dust and debris samples collected by EPA and OSHA and analyzed for asbestos, 48 had levels over 1 percent, the level EPA and OSHA use to define asbestos-containing material. Although early samples from water runoff into the Hudson and East Rivers showed some elevated levels of polychlorinated biphenyls (PCBs), dioxin, asbestos and metals, recent results find non-detectable levels of asbestos, and PCBs and polycyclic aromatic hydrocarbons (PAHs) and metals below the level of concern.”
bullet EPA and OSHA samples from Ground Zero and surrounding areas did not contain levels of lead, iron oxide, zinc oxide, copper or beryllium exceeding OSHA limits.
bullet The EPA “has measured dioxin levels in and around the World Trade Center site that were at or above EPA’s level for taking action.” However, the risk from dioxin is based on long term exposure, EPA claims, adding that the agency and OSHA “expect levels to diminish as soon as the remaining fires on the site are extinguished.” The exact figures of the dioxin levels, however, are startling. More than a year later, the EPA will publish a report which includes the raw dioxin data for this period indicating that dioxins levels on some days were almost six times the highest dioxin level ever recorded in the US (see December 27, 2002).
bullet “Of the 36 samples of volatile organic compounds (VOCs) taken around Ground Zero to assist response workers in determining the appropriate level of respiratory protection, several samples have been above the OSHA standard for workers. None presented an immediate risk to workers, and the levels are expected to decline when the fires are out.” [Environmental Protection Agency, 10/3/2001]

The environmental consulting firm, H.A. Bader Associates, conducts several environmental tests at Fiterman Hall of the Borough of Manhattan Community College, CUNY, (BMCC), located four blocks from the World Trade Center site (see October 1, 2001). The test results indicate “unusually high levels of dioxin in dust samples throughout the building” that are “levels 20 to 90 orders of magnitude above results from other buildings where… [the] firm has tested or cleaned in Lower Manhattan.” An EPA toxicologist who reviews the firm’s data will tell the New York Daily News in February that he believes the levels in the building are “below EPA levels of concern.” [New York Daily News, 2/7/2002 pdf file]
