Mr. Bernard P. Orlan January 15, 2002 Wipe Samples for Metals Page 3 H. S. for Leadership & Pub. Service (SPdM) ATC Project No. 15-19125-0290
Findings
Detectable levels of nine of eleven metals were found in the samples from all eight interior surfaces tested. The highest levels of Al, Fe, Mg, Mn and Ni were found on the Main Lobby floor. Cd and Zn were the highest on the floor in Room 1106 and Cr was the highest in Room 903. The highest Cu concentration was found in the sample from the Cafeteria serving window.
ATC does not know the source(s) of these metals or when they were deposited.
ATC appreciates the opportunity to provide this indoor environmental service to the BOE. Please call (212) 353-8280 extension 212 or 261 if you have any questions.
Sincerely, ATC Associates, Inc.
