"September 18, 2001.
One week after the attacks, the EPA tells the public the air in Lower Manhattan is safe to breathe.
Here's what makes it worse: a federal investigation will later find the EPA didn't have nearly enough data to make that claim. A 2003 EPA Inspector General report concludes the "safe to breathe" statement wasn't supported by sufficient evidence - and that the White House Council on Environmental Quality had influenced EPA's public messaging, pushing for more reassuring language and removing cautionary warnings before they ever reached the public.
That's not a 2026 accusation. That's an established federal finding, more than two decades old.
2001–2002.
Somewhere between 250,000 and 400,000 people are estimated to have lived, worked, attended school, visited, or responded in the area around the World Trade Center during and after the attacks, breathing in a mixture of asbestos, lead, glass fibers, pulverized concrete, and combustion by-products.
More than 91,000 rescue, recovery, and cleanup workers and volunteers are directly exposed at Ground Zero and related sites in the days and months that follow.
In 2002, the World Trade Center Health Registry is created to start tracking what happens to all of them.
The years that follow.
The Registry ends up running for more than two decades, becoming one of the longest post-disaster health studies in the world. It finds associations between 9/11 exposure and asthma, COPD, pulmonary fibrosis, sarcoidosis, GERD, cardiovascular disease, cancer, hearing loss, and cognitive impairment. One Registry study finds confusion and memory loss affecting more than one in five enrollees.
A 2026 CDC review confirms it: people exposed to the attacks now have a higher rate of chronic illness, and a lower quality of life, than the general population.
2010.
Congress passes the James Zadroga 9/11 Health and Compensation Act, finally creating a federal system for long-term medical monitoring, treatment, and compensation for the people who got sick.
2026.
The FDNY's World Trade Center Health Program reports that 10,562 of its members are now certified with at least one physical 9/11-related health condition. 4,257 of them are certified specifically for cancer.
And the number NYC officials now confirm is almost impossible to sit with: more people have died from 9/11-related illnesses than were killed in the attacks themselves on September 11, 2001.
September 8, 2026.
New York City opens a public records portal containing roughly 170,000 pages that had never been released - records on air quality, contamination, and the city's response after the attacks.
Among them are the so-called "68 boxes," records officials say weren't even located until 2025, despite earlier public records requests asking for exactly this material. The release also includes the Harding Memo and documents concerning 7 World Trade Center.
The New York Times reviews the documents before the public release and reports something disturbing: evidence of asbestos in locations across Lower Manhattan, months after the attacks - not just at Ground Zero. Some samples come back below safety limits. Others don't.
A separate EPA survey around this period finds that most New Yorkers who responded wanted more and faster information about air quality, and didn't believe what they'd already been told.
City officials say substantially more records are still coming over the following year.
Right now.
New York City's Department of Investigation is actively looking into what successive mayoral administrations knew about the toxins in the air, and when they knew it. That investigation is still open. Nobody gets to write its ending yet.
What's already certain doesn't need embellishing: the air wasn't declared safe because it was proven safe. Tens of thousands of people were exposed. A generation of responders, workers, residents, and children are still being monitored today, a quarter-century later. And the death toll from what came after September 11 has now quietly passed the death toll from September 11 itself.
The towers came down in under two hours. The consequences are still unfolding, 25 years on, one released page at a time.
Someone who needs to know - the story of 9/11 didn't end in 2001, and for tens of thousands of people, it still hasn't."
