The Towers of Light
The EPA Experience

The US Environmental Protection Agency played a key role in the nation’s response to the September 11, 2001 terrorist attacks on the World Trade Center in Lower Manhattan. To protect public safety and health, EPA coordinated with multiple levels and branches of government to respond comprehensively to the initial emergency situation and the resulting environmental disaster. EPA led or participated in essential response activities including:

  1. the monitoring of air, water and dust for potential environmental hazards;
  2. the vacuuming of debris and dust from streets and other outdoor spaces in Lower Manhattan;
  3. the manual disposal of hazardous waste from the WTC site;
  4. the creation of an online database to report monitoring results to the public and press;
  5. setting up wash stations and providing protective equipment for recovery workers;
  6. and the development of cleaning and testing programs for indoor residences in Lower Manhattan.

Because many of EPA’s day-to-day activities at ground zero are complete, much of the information and data available to the public is now outdated or archived.
