Dear Mr Orlan 1
ATC Associates Inc (ATC) is pleased to provide this report of the results of the wipe samples i f for polychlorinated dibenzo p dioxins (PCDDs)and dibenzofurans (PCDFs) collected on August I 27 2002 at the referenced location The New York City Department of Education (DOE) requested these samples to evaluate possible contamination in the school building
Scope of Work
The samples were collected using gauze pads and hexane as a solvent The solvent was provided and samples were analyzed by Pace Analytical Services Inc (Pace) of Minneapolis MN a laboratory experienced m dioxin analysis The analysis was performed by modified EPA Method 8290 using combined capillary column gas chromatography/high resolution mass spectrometry
Wagdi Abdelshahid Industrial Hygienist of ATC s New York City office collected the samples consistent with generally accepted industrial hygiene practices There were inherent limitations created by constraints of time operational and work practice variability variations in contaminant concentrations and sampling and analytical accuracy The results of the sampling represent conditions found on the date the samples were collected
Results
ATC submitted three wipe samples for PCDDs/PCDFs to Pace for analysis Samples were taken from representative floor areas throughout the building The sample area for each sample was one square meter (1 m^) The areas sampled were
• Main Lobby • Hallway by Room 215 • Hallway by Room 403
