Re: Wipe Samples for Polychlorinated Biphenyls P. S. 234M ATC Project No. 15-19125-0279
Dear Mr. Orlan:
ATC Associates Inc. (ATC) is pleased to provide this report of the results of the wipe samples for polychlorinated biphenyls (PCBs) collected on March 8, 2002, at the referenced location. The New York City Board of Education (BOE) requested these samples to evaluate possible contamination in the school building according to the recommendation of T. Fusillo of Environ Corp., consultant to the parents association.
Scope of Work
Tenzin Namgyal, Industrial Hygienist of ATC’s New York City office, collected the samples.
The samples were collected using sterile gauze pads and hexane as a solvent. The solvent was provided and samples were analyzed by PSC Analytical Services, Inc. (PSC), an American Industrial Hygiene Association-accredited laboratory in Reading, PA. The PCB analysis was performed using EPA Method 8082B.
The sampling was performed 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 dates the samples were collected.
Results
ATC submitted two (2) wipe samples for PCBs (plus one blank) to PSC for analysis. A copy of the laboratory report is provided in the Attachment. The surface area for each sample was 100 square centimeters (lOOcm^).
