New York City has made public a collection of over 170,000 previously unreleased documents detailing air quality conditions in Manhattan following the September 11, 2001 terrorist attacks. Announced on Tuesday by Mayor Zohran Mamdani, the release coincides with the 25th anniversary of the events and fulfills a lawsuit filed by the advocacy group 9/11 Health Watch.
At a press conference held alongside activist and television host Jon Stewart, Mayor Mamdani accused previous administrations of prioritizing liability protection over transparency. “People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air,” Mamdani stated, describing how officials reassured the public about safety at Ground Zero while harboring internal concerns about hazardous contamination.
The documents indicate that asbestos was detected in nearly all testing locations around the site. Furthermore, an October 2001 file known as the “Harding Memo” reveals that an aide warned former Deputy Mayor Robert Harding that the city could face up to 35,000 legal claims. The memo cited health advisories that prompted individuals to return to downtown Manhattan too early, resulting in toxic exposure and emotional harm.
Jon Stewart, a survivor of the attacks, criticized the timeline of disclosure. He noted that officials did not officially recognize the toxicity of the air until October 2001, remarking sarcastically, “So to be fair to them, they only buried that information for 25 years.”
In response to the findings, the mayor announced that the city would invest more than $34 million to publish hundreds of thousands of pages of air quality reports via an online portal over the coming year. He emphasized that the records illuminate what the city knew regarding the toxic environment and how it acted to limit legal responsibility.
Immediately following the collapse of the World Trade Center towers, city and federal officials, including the then-head of the Environmental Protection Agency Christine Todd Whitman, declared the air safe. Whitman later apologized for the statement, asserting that the agency acted with the best available knowledge at the time. However, research has since confirmed that residents and responders inhaled hazardous chemicals.
The health consequences have been severe. Illnesses linked to the dust and smoke have claimed twice as many lives as the attacks themselves. Former FDNY emergency medical technician Elizabeth Cascio recalled the immediate physical danger, stating, “We all knew the air quality was not safe – it was very toxic in terms of how it felt.” She described the instinct to hold her breath upon arrival but acknowledged the impossibility of sustaining that protection against the pervasive particles.
34 million dollars for documents released too late? Accountability matters, but justice for the victims is already gone.
Asbestos nearly everywhere? This confirms what first responders felt in their lungs. The lies cost lives.
Jon Stewart’s sarcasm is painfully accurate. They buried the facts for a quarter-century while people suffered.
I held my breath then and still got sick. How many more families deserve this transparency so desperately needed?
Twenty-five years of silence. The betrayal runs deeper than the dust. Thank you for finally telling the truth.
