CALL FOR PARTICIPANTS IN WORLD TRADE CENTER STUDY TO
DETERMINE PRE-9/11 POLLUTION LEVELS
The U.S. Environmental Protection Agency (EPA) needs your help in its continuing response to
environmental concerns raised by the attack on the World Trade Center (WTC). To better assess file
impacts of possible contamination from WTC dust, the Agency needs to learn what levels of pollution
existed prior to September 11. To do that, EPA needs to test the dust in apartment buildings that were
not directly affected by the collapse.
EPA will soon begin cleaning and testing residential dwellings in lower Manhattan that were impacted by
the collapse of the World Trade Center. In order to establish pre-existing or background levels of
pollution, EPA will sample 28 residential units and 14 common areas within buildings located north of
59* Street.
Your building has been identified as an ideal candidate for the background study due to the building type
(which is typical of housing in lower Manhattan) and its location well north of the WTC site. By
volunteering to have your home sampled for pollutants, you can help fellow New Yorkers while
receiving useful and interesting information about your home environment.
Background samples will be taken fi-om two residential units and fi-om the common areas in your
building, such as the lobby, hallways and/or stairwells. Background samples are defined as samples
taken from apartments and common areas that compare in layout to impacted locations near the WTC
collapse. The background sampling results will be compared to data from buildings near the WTC
Center collapse. The sampling for EPA’s background study will be conducted by licensed contractors
with direct EPA oversight.
In order to participate in the background study, EPA requests that you or your authorized
representative;
Z Agree to participate for a one-time, one-day, nine-hour period between on or about July 29
through August 16,2002, from Monday through Friday (limited number of Saturdays available).
EPA will schedule a time that is convienient;
