INTRODUCTION
AIR STUDY
WARREN COUNTY LANDFILL
NORTH CAROLINA
AUGUST 1997
On August 5 and 6, 1997, Tim Slagle and Jon Vail of the United States
Environmental Protection Agency (EPA), Region 4, Science and Ecosystem
Support Division (SESD) conducted an air quality study at Warren County Landfill,
North Carolina. The study was requested by Waste Management Division, North
Remedial Branch, to determine if PCBs (polychlorinated bi-phenyls) were being
emitted into the ambient air from the landfill.
STUDY AREA
The six air monitoring sites utilized during the study were located within the
fenced boundaries of the landfill (Figure 1) for security purposes. Two sites,
designated A and B, were established adjacent to the vent pipe at the center of
the landfill. Meteorological data consisting of wind speed and direction was
recorded at this sampling location for the duration of the air study. Meteorological
data was recorded at the top of the land fill because the surrounding terrain was
relatively free of obstructions. Site C was located at the northwest corner of the
landfill. Site D was located on the west side between sites E and C. Site E was
located at the southwest corner of the landfill. Site F was located near the
southeast corner of the landfill. The upwind measurements at Site C were used to
determine if any of the pollutants being measured were transported into the area
from other sources.
SAMPLING PROCEDURES
The Air PCB samples were collected by the high volume PUF/XAD method. The
sampling methodology conformed to T0-4 of the Compendium of Methods for the
Determination of Toxic Organic Compounds in Ambient Air. The high volume
sampler utilizes a glass fiber prefilter with polyurethane foam (PUF) and XAD
absorbent cartridge for collection of the compounds in ambient air. Approximately
210 M3 of air was sampled during the 24-hour sampling period.

SAMPLE CUSTODY
At the start of the sampling event, an initial flow rate and an initial elapsed time
reading was recorded from each high volume sampler internal clock. The samplers
were then sealed with custody seals. During the 24-hour sampling event a guard
was posted and the samplers were checked periodically. At the conclusion of the
sampling event, the integrity of the custody seals was verified, .and a final flow
rate and elapsed time were recorded. The sampling cartridges were then returned
to individual sampling jars and sealed with custody tape.
QUALITY ASSURANCE
Co-located duplicate sets of PUF/XAD samplers were operated at sites A and B.
They were .used to show the precision of the monitoring method.
A field blank PUF/XAD cartridge was carried to the field but not exposed. It was
analyzed to document lack of contamination from field transport. Initial and final
flowrates were recorded for the samplers to verify flowrate stability.
ANALYTICAL PROCEDURES
The samples were analyzed by the EPA, Region 4, SESD laboratory in Athens,
Georgia, in accordance with the Analytical Support Branch Laboratory Operations
and Quality Control Manual, September 1990.
The media designed to collect PCBs in air was analyzed by the T0-4 procedure. A
surrogate mixture was added to each PUF/XAD cartridge before extraction. The
particulate filter and PUF/XAD cartridge was Soxhlet extracted for approximately
24 hours using a 5% ether in hexane solution. The sample extract was analyzed
for the target analytes listed in Table 1 by using a Gas Chromatograph equipped
with an Electron Capture Detector.
AIR RESULTS
No PCBs in ambient air at the landfill were detected at sub-microgram per cubic
meter concentrations. The air sample analysis data is attached as Table 2. The
prevailing wind was from the north northwest with an average speed of 2. 7 miles
per hour. Meteorological data is attached as Appendix 1 .
