Release of 170,000 Pages Raises Concerns Over Ground Zero Air Safety

New York City Mayor Zohran Mamdani recently released a substantial collection of records related to the air safety claims following the 9/11 attacks. The release involves more than 170,000 pages, challenging previous assertions about air quality near Ground Zero.

The records, discovered in 68 boxes at the Department of Environmental Protection in 2025, date back to the post-9/11 period. This disclosure comes as the 25th anniversary of the attacks approaches. The tragedy resulted in the deaths of 2,977 individuals, and many more have suffered or died from illnesses linked to exposure to toxic dust and debris, as reported by the World Trade Center Health Program and other health authorities.

In a press release dated September 18, 2001, the then-EPA Administrator Christine Todd Whitman assured the public that the air around the World Trade Center was safe. Mamdani criticized these statements in a recent press conference, highlighting the detrimental effect these assurances had on public health.

The documents reveal that nearly a year after the attacks, asbestos was detected on the roof of a building at 15 John Street, close to the World Trade Center site. Some locations recorded asbestos levels below cleanup benchmarks, while others exceeded them. Health authorities maintain there is no safe level for asbestos exposure.

A February 28, 2002, memo highlighted concerns from Rep. Jerrold Nadler about indoor air quality in Lower Manhattan. The memo warned of possible legal and public-relations issues due to inadequate cleanup efforts. Nadler criticized the Environmental Protection Agency’s decision to transfer air quality monitoring to city authorities without enough oversight. The memo suggested applying for FEMA funds to support indoor cleanup efforts.

Significant concerns were raised about Stuyvesant High School, located near Ground Zero. In August 2002, tests on the school’s auditorium carpet revealed asbestos concentrations at 2.5 million structures per square centimeter. This finding far exceeded EPA cleanup benchmarks, which indicated professional cleaning was needed over 5,000 structures per square centimeter. Efforts to address these findings were communicated to city officials.

Residents of Tribeca, through the Independence Plaza North Tenant Association, voiced concerns over incomplete EPA cleanup efforts. They criticized reliance on visual inspections and urged comprehensive ultrasonication testing to measure asbestos effectively. The association called for thorough cleaning due to ongoing health issues among residents, such as respiratory problems and headaches.

By September 2002, the EPA announced contracts for asbestos cleanup in the downtown area. However, records show asbestos contamination persisted in some apartments for months after cleanup commenced. A couple residing at Independence Plaza North experienced elevated asbestos levels in their apartment in February 2003, emphasizing ongoing risks.
