Additional Air Monitoring in Paterson (AAMP)

Background:
The New Jersey Department of Environmental Protection (NJDEP) initiated an air toxic study in Paterson City in April 2010 to further investigate elevated levels of eight air toxics that were measured during the Urban Community Air Toxics Monitoring Project, Paterson City, NJ (UCAMPP) from November 2005 until December 2006.

Out of 132 air pollutants measured during the UCAMPP study, levels of p-dichlorobenzene were significantly elevated at one of the monitoring locations (176 Broadway) in Paterson for a two month period compared to the other monitoring locations in Paterson and around the state. As a result, NJDEP determined that a further study was needed to determine if the two month elevation was a one time event or whether the levels are an ongoing occurrence. Seven other air pollutants were also elevated at all three sites in Paterson as well as at other air monitoring locations around the state. The levels of these air pollutants (benzene, ethyl benzene, 1,3-butadiene, carbon tetrachloride, chloroform, chloromethane, tetrachloroethylene, and p-dichlorobenzene) were above NJDEP health guidelines at Paterson and at the other New Jersey sites.

Goals of the Additional Air Monitoring in Paterson Study:
There were two goals for the additional air monitoring study. The first was to determine whether the levels of p-dichlorobenzene remain elevated or whether the two-month elevation in p-dichlorobenzene levels observed during UCAMPP was a one-time event. The second was to determine the variation in the levels of the specified air pollutants around 176 Broadway.

Sampling Plan:
NJDEP monitored at and around the site where the elevated levels of p-dichlorobenzene were observed. Two types of samples were collected. One type of sample collected at the same location and in the same way as was done in the earlier UCAMPP study and at the other three air toxics monitoring locations around the state (Chester, New Brunswick and Elizabeth). This sample was collected every twelve days, which coincides with measurements obtained at the three other monitoring locations around the state. This type of sample allowed NJDEP to compare the levels at 176 Broadway to the data collected during the previous UCAMPP study and at the other 3 monitoring sites around the state.

The second type of sample was a different method that measured the eight air pollutants listed above. This method used a small sampling device that does not require electricity so it was placed in multiple locations around 176 Broadway every other month over the course of the year. This type of sample allowed NJDEP to determine the variation of levels of these air pollutants over about a 1 square mile area around 176 Broadway.

Time Frame:
The entire project period was from March 15, 2010 to September 14, 2011. The sampling, itself, occurred from April 2010 through April 2011. The last six months of the project period was needed because the laboratory results lag behind the sampling. During this period, we reviewed the data quality, and analyzed the data for patterns, and wrote the final report. The report was then reviewed by scientists at the NJDEP and USEPA. The sample results were reviewed upon receipt from the laboratories and compared to previous data that were collected in Paterson. If there was an immediate threat to public health and safety, the community would have been notified. The NJDEP was committed to communicating with elected officials and community leaders throughout the project.
