NYC 9/11 Public Portal Document

Bulk dust results listed in ug/wipe were also reported. The highest lead result listed in ug/wipe units was 9.7 ug/wipe from the Manhattan Borough Community College Gym Bleachers on September 28`t'. Lead was also reported at 4.5 ug/wipe in a September 28``' sample from the Stuyvesant High School Elevator. To date, all of the Manhattan Community College and Stuyvesant High School samples were from September 28`x. Lead in three (3) bulk dust samples taken on September 24 from the Southwest Corner of WTC and West Side of Pile were reported at <1 ug/m3.

Lead was also detected in several PS 234 Chambers & Greenwich St Dust Wipe samples taken on September 29"' at levels ranging from 0.15 ug/wipe to 1.5 ug/wipe.

Review of the metals in water sample results from the NYC Response database indicate that many of the database fields are incomplete. The highest level of lead in water, with the notable exception of the Rector St-Runoff sample taken on September 14"' was 35 ug/L. This 35 ug/L result, however, is listed with no sample location.

The Rector St - Runoff sample from September 14' had high levels of all of the target metals, including lead at 1500 ug/L, arsenic at 140 ug/L, and mercury at 9 ug/L.
