I am writing this letter to inform you of the results of the ambient air monitoring that was conducted at your property in December
2003. As you know, the former PCB Landfill is approximately one and a half miles ofa mile southwest of your house. Treatment of
contaminated soil ended in mid-October. Decontamination and removal of the equipment from the site was underway during this
sampling event. I am pleased to report that no PCBs were detected.
A 24-hour air sample was collected using the same procedure as in July and analyzed for PCBs. Results of this sampling and the
previous event are shown below.

Pat ...
Several projects I have handled for the EPA and Corps of Engineers wanted
to have data that didn't have reported "ND" because of explaining what a
ND
represents. No standard methods, but some project take the "Reporting
Limits" given by the laboratory and divide by the volume of air sampled
to
replace the "ND" with a number. For our project, that number would be
1.4
X l0E-6 mg/m3 for the Davis Property and 1.3 X l0E-6 mg/m3 for the
Kearney
Property. The approach I like to take is if the reported value is "ND,"
then I use one-half value of the "Reporting Limits (i.e., 0.5 ug/2 = 0.25
ug) ," then I divide by the volume of air sampled (349.4267 m3 for Davis
Property and 371.0588 m3 for the Kearney Property). If we take this
approach then the concentrations would be 7.15 X l0E-7 mg/m3 for the
Davis
Property and 6.74 X l0E-7 mg/m3 for the Kearney Property.
Of course, during the initial "Background" study, we reported ND because
of
that is what Jim wanted to report.
Give me a call so we can discuss if needed.

Jerry,
I am writing a letter to the Kearneys and Mrs. Davis about the samples
collected at their properties in December. When I report ND, I would
like to include the detection limits. They won't necessarily
understand, but it is something I am writing I want to careful and
accurate. (Ok, I'm a little paranoid.) John forwarded your email with
the results. I didn't understand the comments after the ND values.
Could you explain? What is the correct way to report this?
Thanks,
Pat

We would like to return and monitor the air at your property once treated soils at Warren County PCB Landfill have
been covered, to confirm that ambient air concentrations are still below the state standard. This sampling is
tentatively scheduled for November 2003. We will contact you later to schedule a convenient time for this
sampling.

Jim asked me to check which PCBs were detected during the last sampling
event (FS Week 17A). The positive PCB results were for Arocl or 1242 and
Aroclor 1260 . This i s different from what has been h i stori cal ly detected.
I went back through the old reports ~nd for all of the sampling events since
January 2003 (PDT and full scale) the positive detects have been for Aroclor
1232 and Aroclor 1260. However, all of the positive PCB detects during the
shakedown were for Aroclor 1242 and Aroclor 1260. I am trying to get a copy
of the chromatogr ams for t he FS week 17A event.
If you have any questions, please let me know.

1.0 Introduction
Warren County PCB Landfill
Ambient Air Sampling Methods
Used At Warren County PCB Landfill
To Protect Citizens Health
Ambient air monitoring will be performed at the Warren County Landfill to evaluate the
air quality and document that harmful air pollutants aren't leaving the site during cleanup.
Monitoring of the ambient air involves three groups of pollutants. They are:
• Particulate matter (PM);
• Volatile organic compounds (VOCs); and
• PCBs/dioxins/furans.
Figure 1 illustrates the various samplers utilized to monitor for PM, VOCs, and
PCB/dioxin/furans at the Warren County PCB Landfill.
Figure 1. Ambient Air Monitoring Station At The Warren County PCB Landfill
(Samplers include portable 3-meter meteorological station, PM-10 particulate monitor
and PCB/dioxin/furan monitor.)
- 3 -
2.0 Particulate Matter
Monitoring for particulate matter (PM) involves filtering ambient air containing particles
through a pre-weighted quartz fiber filter (where the particles are retained) maintained in
a aluminum housing. If the aluminum housing contains a size-select sampling head to
allow only PM-10 micron particles to enter the sampler to the filter, then the sampler is a
PM-IO sampler, as illustrated in Figure 2.
Figure 2. PM-10 Sampler For Sampling Particles at Warren County PCB Landfill.
- 4 -
The sampler contains a high-volume pump and flow controller to control the flow of
ambient air pulled through the filter. The sampler also contains a timer so the motor can
be operated without someone present. The field technician installs the filter on the
sampler and sets the timer to operate ~ 24 hours. During the sampling period, particles in
the air are trapped and retained on the filter. The field technician collects the filter and
takes it back to the laboratory to be weighted. The difference in the weight of the filter
before sampling and after sampling ~ 24 hours is the amount of particles sampled from
the ambient air. The volume of gas sampled is divided into the weight gain of the filter to
give an ambient air concentration in micrograms per cubic meters.
As illustrated in Figure 3, the amount of particles retained on the filter is compared to the
United States Environmental Protection Agency (EPA) National Ambient Air Quality
Standard (NAAQS) to determine if a violation of the standard has occurred.
Figure 3. Picture of Quartz Fiber Filter Used to Monitor TSP in Ambient Air.
This monitoring technique is very similar to the hairs in your nose filtering out particles
from the air you breath.
- 5 -
3.0 Volatile Organic Compounds (VOCs)
Volatile organic compounds (VOCs) are those compounds which are very volatile and
are found in the gaseous state. Compounds in this group are similar to the "smell" of
VOCs from fingernail polish, the emissions from a magic marker, or the vapors from
floor cleaners. The sampling system for monitoring ambient air VOCs consist of an inlet
sampling rod, a pump, and a canister to trap the VOCs, as illustrated in Figure 4.
Figure 4. Volatile Organic Sampler at the Warren County PCB Landfill
-6 -
In operation, the ambient air enters the top part of the rod, then is pulled down through
the sampling pump and into a stainless-steel container (canister), where the VOCs are
retained. Figure 5 illustrates the design of a canister.
Figure 5. Canister Used To Contain Volatile Organic Compounds at the Warren County
PCB Landfill.
The canister is returned to the laboratory for analysis. The amount ofVOCs detected are
then compared to EPA's national database.
4.0 Polychlorinated Biphenyls (PCBs)/Dioxins/Furans
The final category of pollutants we monitor at the Warren County PCB Landfill are
chlorinated biphenyl (PCBs), dioxins, and furans. These compounds are very toxic. The
sources of these compounds are combustion of coal at power plants and coolants used in
transformers. These compounds are not very volatile, so we must trap them from the
ambient air with some type of adsorbent. As with the other ambient air monitoring
methods, we will pull a large volume of air through a filter and an adsorbent [ a
polyurethane foam plug (PUF plug)] to trap out the PCBs/dioxin/furans from the air. The
PUF plug is the same material that is found in automobile seats and padding for chairs. It
is perfect for retaining ( extracting) the PCBs/dioxin/furans from the air. Figure 6
- 7 -
illustrates the PUF plug used in sampling for PCBs/dioxins/furans from the ambient air at
the Warren County PCB Landfill.
