On the 25th anniversary of the September 11 attacks, New York Mayor Zohran Mamdani announced the launch of a free online archive containing 170,000 pages of declassified health and safety records related to the World Trade Center disaster. The release marks a significant move toward transparency in one of the most prolonged public health crises in American history.
According to the city administration, the documents contain evidence that local and federal officials were aware of the dangerous airborne conditions at Ground Zero in the weeks following the attacks but failed to adequately warn rescue workers, volunteers, and nearby residents. The materials allegedly show that known toxins, including asbestos, pulverized concrete, and chemical vapors, were present at harmful levels, yet protective measures were neither communicated nor enforced consistently.
The 9/11 health crisis has grown steadily over two decades. Thousands of first responders, construction workers, and Lower Manhattan residents have developed cancers, respiratory diseases, and other serious illnesses linked to their exposure. Official figures from the September 11th Victim Compensation Program indicate that more people have died from 9/11-related illnesses than perished on the attacks themselves on September 11, 2001.
Mayor Mamdani framed the release as an act of accountability. "Never Forget does not mean only remembering the victims — it means demanding honesty about what happened to them," he said in a statement. "These records confirm what survivors and advocates have told us for years: the city government knew the air was poison and did not tell people."
The online portal, which will remain freely accessible, includes internal memos, environmental assessment reports, and correspondence between city agencies and federal emergency management officials. Advocacy groups representing 9/11 responders welcomed the release but cautioned that access to documents alone cannot undo the damage caused by years of delayed action.
Critics of previous administrations have long accused officials of downplaying the health risks to avoid panic and protect ongoing rebuilding efforts. The newly released files are expected to fuel calls for stronger compensation and healthcare protections for those still suffering from 9/11-linked illnesses.
