Mr. Bernard P. Orlan June 19,2002 Air Sampling for Hydrocarbons Page 2 H, S. of Economics «&. Finance (833M) ATCProiectNoM5-1912S:0291
Results
The only HC compound present above the limit of detection was chloroform which was detected in the 1“ floor main lobby sample (concentration of 0.036 ppm), 5* floor hallway (concentration of 0.055 ppm), and 10'*' floor hallway (concentration of 0.036 ppm). Chloroform is used as a solvent for commercial waxes and resins and may have been present as the result of the waxing and polishing of the floors in the school.
None of the other HCs in the panel were present in the other samples above the limits of detection for the analyses.
ATC appreciates the opportunity to provide this indoor air quality service to the BOE. Please call me at (212) 353-8280 extension 212 if you have any questions.
Sincerely, ATC Associates, Inc.
