* This reading exceeds the EPA benchmark. It may not indicate increased risk, however, because these are "snapshots," rather than long-term exposure measurements. Weather and recovery activities at the World Trade Center can cause temporary variations in asbestos levels that affect these snapshots.

DUP - indicates that more than one sample was taken at a particular time; all values are reported.

There may be gaps in daily readings because of relocated construction equipment and variations in sampling locations.
