Update - November 2010:

In May 2010, the NJDEP was informed by Eastern Research Group, Inc. (ERG, Inc), the USEPA national contract lab, that the quality control measures prepared by their analyst were calculated incorrectly for the volatile organic compounds (VOC) that were measured during the Urban Community Air Toxics Monitoring Project, Paterson City, NJ (UCAMPP). The data were corrected using USEPA approved procedures which resulted in changes to a small number of data points less than 4%). The original dataset was updated with the recalculated values and statistics were again applied to the updated dataset. Because the number of affected data points was so small, and because most of the changes were small themselves, these adjustments to the dataset did not result in any changes in the final conclusions that were reached in the report.
