As recently as last month, private and public tests still
detected
asbestos in some lower Manhattan buildings.
Tests by a New York University team also found minimal
levels of
chromium, dioxin, lead, nickel and polychlorinated biphenyls, or PCBs.
The U.S. Geological Survey found that the dust could be
caustic when
mixed with water, apparently because of a substance in concrete. And
tests conducted for the city health department found fiberglass, a
possible carcinogen, in nearly half of the samples.
Labor groups, environmentalists and downtown residents say
that federal
and local agencies downplayed potential risks posed by the dust, leaving
residents confused.
On Sept. 13, the EPA issued a statement that said:
"Sampling of bulk
materials and dust found generally low levels of asbestos ... the
general public should be very reassured by initial sampling."
But EPA officials say they also warned residents and
cleaning companies
that they should presume the dust had asbestos levels high enough to
require professional contractors with respirators to clean up heavy
deposits.
"We knew that there was asbestos in the dust and the
recommendation was
to use professional abatement contractors," agency spokeswoman Bonnie
Bellow said.
"I never heard EPA say that," said Jessica Leighton,
assistant
coiranissioner of the New York City Department of Health. "It was not the
assumption we're working under."
Instead, the city health department said as early as Sept.
17 that
residents could clean their own apartments using wet rags, mops and
high-efficiency vacuum cleaners.
Leighton said that recommendation applied only to buildings
where
landlords had not detected enough asbestos to require professional
cleaning.
But that qualification wasn't mentioned on many health
department press
releases and fliers posted on downtown buildings. And the distinction
was lost on many residents, who cleaned heavy dust deposits in buildings
that hadn't been tested, said Madelyn Wils, chairwoman of lower
Manhattan's community board.
"At the time when people were starting to get back into
their homes, it
was unclear," she said. "There was no leadership from the city, state or
federal government on this."
Artist Nancy Manter said she is recovering from pneumonia
she developed
after cleaning inches of dust from her apartment two blocks from ground
zero.
"Cancer, of course, is a huge concern," she said. "You feel
like you're
not being told the truth."
Around Thanksgiving, more than 1,000 Southern Baptist
volunteers
cleaned apartments around Battery Park City through a program that sends
volunteers to disaster areas.
The city Office of Emergency Management coordinated their
efforts and
the health department provided volunteers with high-efficiency vacuum
