Daily Environmental Monitoring Summary
The U.S. Environmental Protection Agency (EPA) and other federal, state
and local agencies have collected extensive environmental monitoring data
from the World Trade Center site and nearby areas in Manhattan, Brooklyn
and New Jersey. Since September 11, EPA has taken samples of the air,
dust, water, river sediments and drinking water and analyzed them for
the presence of pollutants that might pose a health risk to response workers
at the World Trade Center site and the public. The samples are evaluated
against a variety of benchmarks, standards and
guidelines established to protect public health under various conditions.
With the conclusion of recovery efforts at ground zero in early June,
EPA discontinued its outdoor sampling of pollutants in lower Manhattan
associated with the World Trade Center. The outdoor sampling has generally
shown no presence or very low levels of pollutants in recent months. The
fires have been out for months, recovery activities are completed, the
barge operation is shut down and our sampling generally shows that air
quality in lower Manhattan is back to normal levels prior to September
11. EPA is now focused on providing local residents the assurance that
their homes have been cleaned properly.
Recovery operations at the Staten Island landfill have also concluded;
however, EPA will conduct monitoring there for several additional weeks.
In addition, EPA and the city will do specialized monitoring in lower
Manhattan when the exteriors of buildings are cleaned and when we clean
in people's homes.
As a result, regular daily monitoring summaries will no longer be posted.
Please see the list below for all available summaries. Additional data
will be posted on this page as warranted, or as it becomes available.
Long-term summaries of the data
are also available.
