This is a repeat of the September 28, 2001 testing. The resulting data will be similar and also compared to the September 28, 2001.

Analytes 70 and 71 (phenol and 2-methylphenol) were not measured in the September 28, 2001 samples. These two compounds are in the EPA database but are from source dominated sampling events and so should be higher than background. The EPA database in this case will be a benchmark, but a high benchmark. Phenol is in the EPA base database that evaluated outdoor at and indoor air in buildings across the country. This will provide background data.
