Results of Dust Wipe Sampling Twenty (20) dust wipe samples were collected from inside the school building and three (3 ) from the playground at locations indicated to ATC by ENVIRON representative. Laboratory analysis is shown that all dust wipe samples collected contain lead below the floor and windowsill surface clearance guideline levels of 40 pg/ft" and 250 pg/fV respectively. See laboratory report and chain of custody for more details.
Limits of the limited dust wipe sampling Dust wipe sampling was requested by NYC-BOE at ENVIRON recommendation. The results of this report are applicable for the time and locations the testing was performed. If questions arise concerning lead content in or on components and/or locations not tested by ATC, then additional testing services should be procured. ATC makes no representation or warranty concerning the standards and specifications provided in the HUD Guidelines and the NYC-BOE protocol.
It is our pleasure to provide these limited lead services to New York City Boai'd of Education. If you have any questions regarding this limited lead-in-dust wipe sampling, please do not hesitate to call me at (212) 353-8280 extension #261.
