S&ME Project No. 1054-97-670
...
S&ME, Inc. has completed an evaluation of the landf~l cap for the Warr.en County PCB Landfill . I
in Warren County, North Carolina. The evaluation was performed in general accordance with
our Work Plan for Excavation, Handling, and Stor~ge~PCB-.tontaminated Soils, dated
February 13, 1997. This report includes a brief description or'~e project, our field and
laboratory testing procedures, test results, and conclusions.
PROJECT INFORMATION
The Warren County PCB Landfill occupies 2.5-acres of a 19.3-acre site located on the east side
of SR 1604, approximately two miles east of the intersection of SR 1604 and US 401 South,
approximately two to three miles south of Warrenton, North Carolina. Construction of the PCB
landfill began in June 1982 as the result of a joint agreement between the State of North Carolina
and the US Environmental Protection Agency. The PCB landfill is owned and maintained_ by the
State.

FIELD EVALUATION
S&ME Project No. I 054-97-670
May 2. 1997
An S&ME professional engmeer and engmeenng technician, both experienced in landfill
closures, evaluated the landfill cap at two sampling locations on February 28, 1997. The number
of sample locations were limited to two since the cap evaluation was supplemental to the primary
task of obtaining samples of landfilled materials for pilot bench studies. Only two locations were
selected for obtaining those landfilled materials.
The landfill cap consists of two feet of vegetated cover soil and a 10-mil thick Polyvinyl
1wb'7.
Chloride (PVC) liner underlain by th,re'e feet of compacted clay liner. The objective of the field
evaluation was to ~~the soil cover, PVC liner and clay liner at the two sample locations.
This evaluation was completed with a combination of field observations, procurement of
relatively undisturbed samples and laboratory testing. The following sections describe the field
activities and observations.
Soil Cover and Clay Liner
The investigation began during advancement of the two boreholes at the two sample locations
( designated as B-1 and B-2). During this phase, two near-surface relatively undisturbed soil
samples were obtained at each !f}f le location by pushing a thin-walled Shelby tube from the
ground surface to a depth ~o feet. The cover soils were determined to be approximately 22 . 1
inches thick at each sample location and visually field classified as a silty clay. A good stand of
grass was noted above the cover soil
Once the two cover soil samples were obtained, a small excavation was opened at both sample
locations that extended to the PVC liner. An approximately 16-inch diameter hole was then
opened in the liner at each sample location.? Three undisturbed samples were obtained from the
underlying clay liner at a depth of zero to two feet below the PVC liner: The clay liner was .----,
measured to be approximately three feet thick at the two sample locations. This measurement

PVC Liner
A second excavation was made adjacent to the borehole sample locations for the purpose of
sampling and evaluating the PVC liner. The second excavation at each of the two sample
locations was approximately five feet-six inches by five feet-six inches in plan dimensions and
extended vertically to the top of the PVC liner. The second excavations' opening sizes were
approved on-site by DWM representative~e initial visual evaluation indicated that vegetative
roots were penetrating the PVC liner seams at both locations. The exposed PVC liner was
cleaned by sweeping the remaining soil and was further visually evaluated.
At sample location B-1, the first two to four inches of cover soil directly above the PVC liner
was excavated using a large stainless steel spoon. This was done to limit contact with the PVC
liner and thus avoid damage. At this sample location, the PVC liner had adhered to a set of dozer
tracks within the underlying clay. An approximately five-foot by four foot section of the .PVC
liner was cut from the bottom of the excavation. This sample cut was positioned to split the set

of dozer tracks to allow a smooth repair. The cut PVC sample was washed with detergent and
potable water and cleaned at the on-site decontamination area to remove adhered soil prior to
transporting to our laboratory for testing.
The cover soil at sample location B-2 was excavated with a plastic shovel, that was used to
wedge the soil cover from the excavation area. The shovel came in contact with the PVC liner at
several places forming a pinhole in the liner. The PVC liner at Sample location B-2 had two
small tears. One was attributed to the excavation of the cover soils and had no vegetative root
penetration. The second tear measured approximately one inch by a half-inch and had evidence
of vegetative root penetration. An approximately five foot by five foot section of PVC liner was
cut, washed and cleaned similarly to Sample B-1. Following cleaning, Sample B-1 was held to
the sunlight to inspect for pinholes. Approximately 20 pinholes were observed in this PVC liner
section.
PVC liner Sample B-1 was delivered to S&ME's subsidiary, Singleton Labs, Inc., located in
Knoxville, Tennessee, for physical property testing. Liner Sample B-2 was delivered to our
Charlotte, North Carolina office for seam testing. These tests are discussed on page SH( of this
report. fift,
The two PVC liner sample openings were patched by Plastic Fusion Fabricators, Inc., of
Huntsville, Alabama, immediately after the cuts were made. The patching was observed by an
S&ME senior engineering technician experienced in plastic liner repair. At each patch, the
existing PVC liner edge was cleaned with detergent and potable water then dried. Variations
were made in the original work plan by not placing geosynthetic clay liner (GCL) on top of the
exposed clay. We concluded that to do so in such a confined space could strain the PVC liner
seam.

Pieces of new 20-mil PVC liner were sized to overlay the sample cuts. The PVC liner overlap
was approximately three inches for sample location B-1 and two and one-half inches for sample
location B-2 . Two patches were required for B-2 due to the existing PVC seam being so close to
the excavation edge. The patches were glued to the existing PVC liner using a paintbrush to
apply PVC glue. Pressure was applied to the liner seam to form a chemical bond. The integrity
of the glued seam was tested by the blunt-end pick test in accordance with USEPA Technical
Guidance Document EP A/530/SE-91/051, Inspection Techniques for the Fabrication of
Geomembrane Field Seams, Section 9.5. Observations concluded that the patched seams bonded
adequately and passed the EPA test method.
Before backfilling the sample locations, a filter fabric was placed within the excavations directly
above the PVC liner to help reduce potential damage to the patches during backfilling. The
adjacent stockpiled cover soils were used to backfill the excavations. The replaced soils were
compacted with a manually operated compactor and the disturbed areas were then re-seeded.
This completed the field activities.
LABORATORY TESTING
Soil Cover and Clay Liner
Laboratory testing was performed on undisturbed soil samples of both the cover soils and clay
liner taken from both sample locations. Tests were made on one sample from the soil cover at a
depth of zero to two feet at each location, and two samples from underlying clay liner at depths
of two to four feet (below the ground surface) at each location. The testing consisted of unit
weight, Atterberg limits, grain size analysis, moisture content, specific gravity and permeability
testing. Geo Testing Express of Acton, Massachusetts performed the soil laboratory testing.
Based on the unified soil classification system, the cover soil and clay liner soils classify as a
silty clay, CH. The laboratory permeability test results indicate permeabilities ranging from 1.5

Soil Cover and Clay Liner
CONCLUSIONS
S&ME Project No. 1054-97-670
May I, 1997
Based on the field and laboratory testing performed, the soil cover and clay liner at the locations
sampled appear to be in good condition and performing to t intent of its desig . The soil cover
had a good stand of grass and showed no evidence of erosion. \ -~ I " ~¥.~ -):~~~~,> \W' ~, ,~ '¥ \' ~"\ V
The clay liner at the locations sampled had no visual evidence of desiccation cracks or softness. ~ ~ \
Based on the density and moisture content tests, it appears that the soil liner received a ¥' ~
reasonable compaction effort. Also, the permeability tests performed are indicative of well-'tJ
compacted clays based on our experience with similar type soils. The permeability test results
indicate a lower permeable soil liner than typically specified for the soil component of a solid
waste landfill cap system.
Based on the above limited field observations and laboratory test results, the soil cover and
underlying clay liner beneath the PVC liner at the locations sampled appear to be providing
satisfactory performance.
PVC Liner
Based on our limited field observations, the PVC liner at the locations sampled appears to be in
fair condition. The seams showed signs of root penetration along several seam sections.
Pinholes were observed in PVC Sample B-1, although some of the pinholes may have resulted
from damage during excavation of the soil ~over. No pinholes were observed in PVC liner
Sample B-2. The PVC liner appeared to be intact with no noted signs of excessive deterioration.
The laboratory test results indicate that some degradation in the PVC has occurred over time.
The elongation properties and dimensional stability do not meet current typical specifications

however, the PVC liner appears to have provided
The results of the peel test performed on the seam sample indicate the PVC seam does not meet
current industry specifications for 10 mil PVC liner seams. The low peel test results may be a
result of the root penetration or a degradation of the PVC glue used to bond the seams.
QUALIFICATIONS OF REPORT
Our evaluation of the Warren County PCB Landfill cap was completed in conjunction with
procurement of landfilled soils for pilot bench testing which resulted in the number of sample
locations for our evaluation being limited to two. Two sample locations do not provide adequate
data to statistically evaluate such items as determination of variance, confidence intervals, etc.
To gain a reasonable understanding of the landfills overall condition, there must be a
significantly larger number of sample locations. Accordingly, our investigation, test results and
conclusions are indicative of conditions at the specific sample locations and should not be
interpreted to represent conditions across the entire landfill.
Our evaluation was performed in general accordance with our Work Plan for Excavation,
Handling, and Storage of PCB Contaminated Soils, dated February 13, 1997. Recommendations
for remedial action in regards to the cover soil and liner system were beyond the scope of our
services. Observations and conclusions contained in this report are based on our experience with
landfill liner systems and current industry design and construction standards.
