NYC officials release unseen post-9/11 air quality documents

New York City has unveiled thousands of long-hidden documents concerning air quality and health risks in the aftermath of the 9/11 attacks. The city unveiled a new online portal on Tuesday, teeming with over 170,000 pages of files from various agencies related to post-9/11 air quality and health concerns. These documents suggest that worries about hazardous air endured for months post-attacks, despite assurances from officials that the air was safe to breathe.

Among the recently released materials are 68 boxes of documents, uncovered last year, the Harding Memo, and records of World Trade Center 7. These documents reveal what the city knew about the toxic air around Ground Zero, when it became aware, and how it attempted to minimize liability, as stated by Mayor Zohran Mamdani at a news conference alongside other city officials and 9/11 health advocates, including comedian Jon Stewart.

Mayor Mamdani emphasized that the city owes transparency and accountability to the families, survivors, and first responders whose lives were altered by the September 11th attacks. He highlighted that for too long, New Yorkers have had to fight for access to records they should have had from the outset. The portal marks an enduring commitment to honor the deceased, support those with lasting health issues, and provide answers to thousands of New Yorkers.

Health officials found evidence of asbestos in the air at least 10 months after the attacks, contradicting repeated assurances that the air was safe. Toxic air, contaminants, and particles lingered in window sills, air conditioners, pets, and clothes for months, as Jon Stewart pointed out. Everyone knew, and now it's evident that the city was aware of this too.

Former Mayor Eric Adams' spokesman noted that any post-9/11 air quality documents must be released and examined, but Adams neither created nor concealed records from prior administrations. CBS News New York reached out to former mayors Rudy Giuliani, Michael Bloomberg, and Bill de Blasio for comments but received no response. Mamdani announced the settlement of two lawsuits filed by 9/11 Health Watch, concluding a lengthy legal battle over the records.

The Harding Memo, discovered earlier in the year, discussed the potential for lawsuits from individuals claiming exposure to toxic air just weeks after the attacks. Former Mayor Giuliani's memo predicted that thousands of New Yorkers would experience severe health effects. The records also contain multiple reports documenting asbestos levels around the area, some showing lower levels within environmental and worker protection limits, while others indicate higher levels, though many lack written analyses of the results.

More documents are anticipated to be added regularly. The city plans to appoint individuals to assist eligible New Yorkers in utilizing these documents as proof of exposure to access federal health programs.
