other adverse lung health effects (more than 1 additional case in 10,000 people exposed). For individuals who conduct frequent cleaning of their residences, or participate in the EPA cleaning/sampling program (described below), it is unlikely that their exposure would resemble these worst-case conditions. Residents who follow these cleaning recommendations would not be expected to have any significant increased risk of cancer or other long-term health effects due to asbestos or quartz.

Based upon the conclusions of their investigation, NYCDOHMH and ATSDR made the following recommendations (NYCDOHMH/ATSDR, 2002):

• Because more asbestos, synthetic vitreous fibers (e.g., fiberglass), mineral components of concrete (quartz, calcite, and portlandite), and mineral components of building wallboard (gypsum, mica, and halite) were foimd in settled surface dust in lower Manhattan residential areas when compared to comparison residential areas, the New York City Department of Health and Mental Hygiene and the Agency for Toxic Substances and Disease Registry are recommending that people continue to conduct frequent cleaning with HEPA vacuums and damp cloths/mops to reduce the potential for exposure.

• To ensure that the recommended frequent cleaning is effective and to ensure that the health of the people of New York City is protected, the New York City Department of Health and Mental Hygiene and the Agency for Toxic Substances and Disease Registry are recommending additional monitoring of residential areas in lower Manhattan. In addition, an investigation should be conducted to better define background levels specific to the city of New York for asbestos, synthetic vitreous fibers, mineral components of concrete (quartz, calcite, and portlandite), and mineral components of building wallboard (gypsum, mica, and halite).

■ Lower Manhattan residents concerned about possible World Trade Center-related dust in their residential areas can request cleaning and/or testing from the Environmental Protection Agency as part of their current clean-up program (see next section).

VI.b.2. The Multi-Agency Task Force Efforts Led by US EPA EPA and its federal, state and city partners have begun to clean up residences impacted by the collapse of the World Trade Center. The clean-up covers residential units south and west of Canal, Allen and Pike Streets, river to river. This effort is being coordinated by the multi-agency Task Force on Indoor Air in Lower Manhattan created by the EPA Administrator. Much of the information on this clean up effort can be found on the web at http://www.epa.gov/wtc. The clean-up includes:

upon request, the clean-up of residential units, using certified contractors, with followup testing for asbestos in the indoor air, or; testing-only of asbestos in the indoor air; reimbursement for HEPA (High Efficiency Particulate Air) filter vacuums; distribution of health and cleanup information;
