Ground Zero’s Toxic Dust

EPA’s new, supposedly improved sampling plan to test for residual toxic dust from the environmental disaster of 9/11 was released Tuesday evening to a response that ranged from “serious concern” on the part of Senator Hillary Clinton to dismay among community activists.

“[I]t appears at first glance that the EPA’s long-awaited plan has been designed in a way that is fundamentally inadequate to determine the true extent of WTC dust contamination,” said Congressman Jerrold Nadler of the Eighth District which includes Ground Zero.

“While we are pleased that EPA agreed to test workplaces as well as residences,” said David Newman, industrial hygienist for the New York Committee for Occupational Safety and Health and a member of the WTC Expert Technical Review Panel which has been meeting with EPA for the last year in an effort to arrive at a scientifically valid plan, “that is a hollow promise if employers can bar access for testing.”

Newman was referring to an aspect of voluntary testing which many community activists feel could make it impossible to get scientifically valid results: If EPA relies only on buildings whose landlords have volunteered to be tested, those are the buildings that are most likely to have been adequately cleaned. In office buildings, employees who are worried about what they may be getting exposed to at work will be at the mercy of the decisions of their employers who may be afraid of the liability issues that could ensue from testing.

Other problems with the plan include its reliance on a WTC ‘signature’ which would supposedly insure that contaminated dust that might be found in people’s homes indeed came from the disaster. Community activists have argued that the contents of the buildings were diverse and that nature did not obligingly mix them together into a homogeneous blend. This belief is borne out by experience: Independent testing performed in the years following 9/11 showed some apartments to have high levels of antimony; others, high levels of asbestos or lead, etc.

EPA’s initial plan as laid out by James Connaughton of the White House Council on Environmental Quality (the organization that changed at least one of EPA’s press releases following 9/11, turning cautionary statements about asbestos into reassurances) was to use asbestos as a surrogate for all the contaminants that might remain in people’s homes. This suggestion was denounced by organizations such as 9/11 Environmental Action and the Sierra Club as well as being severely critiqued by independent experts. Asbestos was then replaced by two ‘signatures’, one for the collapse of the towers, the other for the fires that burned and smoldered for several months. The fire signature idea was abandoned. The collapse signature has metamorphosed several times. A few months ago it was to be slag wool. The current plan adds gypsum and concrete; the latter a contaminant too heavy to have travelled far from Ground Zero. The chameleon nature of the WTC signature underscores the dubiousness of the whole ‘signature’ notion since the essence of a signature is its constancy.

Even if EPA were to arrive at a reasonable plan, there are still problems with the way it would be executed. Residents who took part in EPA’s first cleanup, begun in September 2002, witnessed equipment that broke down, fans for air tests that were never turned on or, when they were turned on, were placed facing the wrong direction. Some community activists, including this writer, have argued for third party monitoring to prevent a repeat travesty.
