Pictures from the World Trade Center Response

Monitoring the Air and Water

For months after September 11, EPA took samples of the air, dust, water, river sediments and drinking water and analyzed them for the presence of pollutants that might pose a health risk to response workers at the World Trade Center and Pentagon sites and the public. These monitoring data are available both in table form and in summaries.

Dust Suppression and Removal

Within days of the disaster, EPA had ten vacuum cleaner trucks blitzing the financial district. Power washers cleaned building fronts and wet down streets and sidewalks to capture the dust prior to vacuuming.

Once Wall Street reopened, three of the giant vacuums, each capable of capturing 15 tons of solid material, began systematically cleaning streets and sidewalks, parking areas, parks and playgrounds in the impacted area.  Sandboxes were the most time consuming … all the sand had to be removed and replaced.

To insure that dust was not tracked into the clean areas by people and vehicles leaving the work zone, EPA established a number of wash stations . Workers coming off the site had their boots washed. Cars and trucks were power-washed and debris being hauled to piers was wetted down and covered so dust did not fly about.

This map shows the areas that were cleaned as of October 15, 2001. The recovery effort concluded in June 2002.
