New York City Releases Thousands of Pages of Undisclosed 9/11 Air Quality Records

New York City has released more than 170,000 pages of previously undisclosed records regarding air quality following the September 11, 2001, terrorist attacks. The documents, which were discovered last year in 68 boxes stored in a city government office, indicate that municipal officials knew conditions around Ground Zero were unsafe to breathe despite providing repeated assurances to the public that the air was safe. Mayor Zohran Mamdani announced the release on Tuesday, ahead of the 25th anniversary of the attacks. The records include contamination data collected by local environmental agencies, air quality reports, and internal communications. One specific document, the Harding Memo sent to then Deputy Mayor Robert Harding, revealed that officials anticipated thousands of potential lawsuits due to air exposure and a lack of safety equipment, while also discussing ways to limit the city's legal liability. Mayor Mamdani stated that more people have now died from 9/11 related illnesses than were killed on the day of the attacks. According to the 9/11 Memorial, at least 140,000 people have enrolled in the World Trade Center Health Program, and 49,000 have been diagnosed with certified WTC related cancers. The city is creating a searchable public portal for the documents, which were released following a lawsuit by the advocacy group 9/11 Health Watch. Jon Stewart, a longtime advocate for survivors and first responders, appeared at the announcement and stated that the city covered up the danger to return to business as usual.
