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 February 5, 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 parent’s association.
SCOPE OF WORK
Wagdi Abdelshahid, 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 8O82B.
ATC’s findings and conclusions are based on the laboratory sample results and the conditions
present in the school at the time of the assessment.
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.
WIPE SAMPLING 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 sample area for each sample was 100
square centimeters (100cm-).
