Air Monitoring in Paterson (AAMP)
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
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.
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.
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.
