was conducted for the specific pollutant.

Meteorological stations were also established following the attack. Six stations were set up by the U.S. Department of Interior, and one station was set up by EPA. These meteorological data, in conjunction with monitoring data, are being used by EPA researchers to model and recreate the potential exposures that might have occurred immediately after the collapse of the WTC buildings. Some important preliminary results of the modeling efforts are presented in this report. The overall modeling analysis, when complete, will be presented in future EPA reports and assessments.

In addition to air samples, bulk dust, water, river sediments, and drinking water samples were collected from sites associated with the WTC and surrounding areas to determine the degree to which the disaster may have caused contamination of these media. Sampling and analyses were conducted by various agencies, including but not limited to, EPA Region 2, the United States Geological Survey (USGS), NYSDEC, and the New York State Department of Health (NYSDOH). Between September 11, 2001, and January 14, 2002, more than 150,000 sampling results were reported for the WTC and other New York and New Jersey sites. Results were reported for over 500 substances (statistics from the second of three trend reports; the third is cited as EPA, 2002a).

Although the data generated since September 11 included results for air, bulk dust, water, river sediments, and drinking water, the focus of this evaluation is on the air sampling, with some discussion of the bulk dust as it relates to asbestos and other contaminants. It should be noted that none of the drinking water samples were found to have concentrations that exceeded any of EPA’s Maximum Contaminant Levels (MCLs) for drinking water.
