Joint Meeting of PCB Landfill Science Advisors and State Staff
July 3, 1996
Raleigh, North Carolina
PCB Landfill science advisors Joel Hirschhorn and Patrick Barnes met with
Division of Waste Management staff on July 3, 1996, at 10 am in conference room 3 at
the division office in Raleigh. The purpose of the meeting was to discuss the sampling
plan for the PCB Landfill.
Present for the meeting were Joel Hirschhorn, Patrick Barnes, Bill Meyer,
Sharron Rogers, Pat Williamson, Larry Rose (hydrogeological technician), and three
geologists with the division--Bob Glaser, Pete Doorn, and Grover Nicholson.
At the beginning of the meeting, Mr. Hirschhorn said that he had reviewed the
information on the sampling event in July 1994, as well as the report prepared by Ms.
Pauline Ewald, head of ECO, and the subsequent letters criticizing her report. He said
he wanted all details handled before the upcoming site investigation is conducted to
prevent mistakes of the past from occurring again. He suggested a detailed report on
all decisions and the basis for those decisions be developed and presented to the PCB
Working Group.
There was a general discussion about the proposed sampling plan prepared by
Mr. Barnes. Mr. Barnes wanted all of the sampling to be conducted at one time,
including some points that were fairly distant from the landfill. Mr. Meyer and the
division staff said that some of the sampling points needed to be closer to the landfill.
Mr. Meyer offered to put in nine new groundwater monitoring wells and to sample
them as well as everything that currently exists on the site (ie., leachate, landfill
contents, etc). He and the staff felt there was no need for the more outlying sample
points suggested by Mr. Barnes unless results from closer samples indicated the
landfill is leaking.
Mr. Meyer proposed doing the sampling in phases. He said he had to be able to
defend the sampling, both technically and economically, to the General Assembly. He
felt that if the first round of sampling indicated a leak, then he could defend the need
for additional sampling on a technical and economic basis.
The group agreed to put in eight new groundwater monitoring wells adjacent to
the landfill plus one hydropunch at the seep located in the northwest corner of the
landfill, one well near the head of each of four draws leading from the landfill (four
wells total unless nested), and three background monitoring wells. Mr. Hirschhorn
suggested that the three background monitoring wells be located one to two miles from
the landfill at the following locations: one in the northwest quadrant across Richneck
Creek; one in the southwest quadrant on property owned by the county; and one in the
northeast quadrant.
Mr. Barnes agreed to draft a new sampling document by July 17 based upon the
revisions agreed to by the group. This will include a new map showing the sampling
points. Mr. Hirschhorn suggested that the revised monitoring/sampling document
should be jointly signed by the science advisors and the state. The science advisors
and the state will contribute specific parts of this detailed report. When the document
is complete and signed, it will be presented to the PCB Working Group for approval.
The group approved Mr. Hirschhom's suggestion.
The group also agreed on the following:
that any laboratory results would be sent simultaneously to the
science advisors and the state
-that Triangle Lab in the Research Triangle Park would conduct the
testing for dioxin/furans by the 8290 method
that samples sent to the State Laboratory of Public Health for analysis
would be "blind" with only general descriptions such as sediment,
water, etc.
that Mr. Barnes will be on the site during the sampling event
that Mr. Barnes will have the "key" to the laboratory samples
-that there will be no split samples
-that sediment and surface water samples will be tested for PCBs and
dioxin only
that there will be
1 trip blank every other day of sampling (water)
3 equipment blanks (water)
1 soil blank
1 surface water sediment blank to be analyzed only if there is a hit
1 hydropunch (soil)
4 sediment samples
5 surface water samples
3 background monitoring well samples (groundwater)
15-19 groundwater samples from monitoring wells adjacent to the
landfill.
soil samples from borings (monitoring wells) adjacent to the
landfill (Patrick will discuss with Bill to determine number)
Mr. Meyer said he would
check with the state lab for detection limits for PCBs + /-10 ppt
-talk to lab personnel regarding the routine detection limits for
organics
-prepare an analysis chart.
Conclusion
A detailed sampling/monitoring plan for the PCB Landfill, including
justifications for decisions regarding this plan, will be prepared and signed by the
science advisors and the state, and then presented to the PCB Working Group for
approval.

MEMORANDUM
To: Bill Meyer
From: Bob Glaser, Grover Nicholson, Larry Rose, and Pete Doorn
RE: Proposed Sampling for the PCB Landfill
Mr. Barnes, Science Advisor for the Warren County Working Group, has proposed another
sampling program for the PCB Landfill. This program is described in the 6/13/96 draft
document titled "Warren County PCB Landfill, Supplemental Site Investigation Plan".
Members of the Division staff have reviewed the sampling program and discussed, at length,
the program with Mr. Barnes. From the review and the discussions, the staff believes that
Mr. Barnes is approaching this site as if little or no previous work had been done. It also
appears that Mr. Barnes' approach assumes that the contents of the landfill are in question and
a release may have occurred anytime between 1979 and 1996. In response to Mr. Barnes'
proposal, the staff has developed an alternate sampling program. The staff's program will
generate data to supplement the existing data. In the development of this plan, the Division
staff assumes that: 1) if a release has occurred, then the release is continuous or cyclic; 2) the
movement of contaminants would be limited because of their low soluability; 3) the contents of
the landfill are known; and 4) the landfill construction and filling procedures are known.
After reviewing both sampling programs, one can see that there are significant differences in
the approach and scope of work. Mr. Barnes' approach is to sample along each of the
contaminant pathways (overland flow and movement via ground water) from the landfill to the
adjacent surface water. The scope of work includes: 1) the collection of soil and ground water
samples adjacent to the landfill; 2) ground water and surface water samples in each of the
draws; and 3) surface water and sediment samples from Richneck Creek and the unnamed
tributary. The Division staff's approach considers ground water as the only transport
mechanism for the lateral movement of contaminants. The scope of work includes the
installation of nine additional wells, to further characterization of the ground water flow
adjacent to the landfill, and implementation of a ground water monitoring program.
As mentioned above, the staff has discussed the merits of both proposal's with Mr. Barnes.
These discussions have helped the staff understand the rationale used in developing Mr.
Barnes' proposal, however, they have been unsuccessful in moving us towards a compromise.
One approach the Division/Department may consider in resolving the differences in the two
proposals is to hire an independent, third party contractor, to review both workplans.
GOAL:
NORTH CAROLINA DIVISION OF WASTE MANAGEMENT
PROPOSED PCB LANDFILL SAMPLING PROGRAM
The goal of this sampling program is to confirm the ground water flow direction in the vicinity
of the landfill and monitor the ground water quality downgradient of the landfill. The
Division staff considers ground water to be the contaminant pathway of concern for the
contaminants in the landfill.
SCOPE OF WORK
The scope of work includes the installation of nine additional ground water monitoring wells
and implementation of a ground water monitoring program.
The nine wells would complement the existing monitoring system and should address any
unresolved questions pertaining to ground water movement in the vicinity of the landfill.
Once the wells are installed, a monthly water level monitoring program should be implemented
for one year. The one year monitoring requirement is necessary to evaluate any seasonal
variation in the ground water flow direction. At the end of the one year, a ground water
quality monitoring program would also be implemented at each of the downgradient
monitoring wells and an upgradient well(s).
The specific locations for the nine additional wells are identified on the attached figure. The
list of constituents to be monitored in the ground water would include each of the constituents
on Table 1 (under the heading of groundwater) in Mr. Barnes 6/13/96 draft "Supplemental Site
Investigation Plan" .
EVALUATION OF DATA
After each water level monitoring event and each ground water quality sampling event, the
data would be evaluated to determine if the appropriate zones are being monitored and
adjustments to the ground water monitoring.program would be made.

SUPPLEMENTAL SITE INVESTIGATION PLAN
PAGE 02
Barnes, Ferland and Associates, Inc. (BF A) has developed the following ''Supplemental Site
Investigation Plan" (Plan) to acquire more detailed information for determining the environmental
impact associated with the landfill and for planning the scope of the remedial design program.
The objectives of this Plan are to determine the:
• Geological setting including definition of soil and rock types, penneable and confining
layers, fractures and faults, hydraulic properties and potential contamination pathways;
• Direction and rate of groundwater and surface water t1ows and seasonal water table
variations;
• Location and extent (both vertical and horizontal) of soil and groundwater contamination
at discrete intervals;
• Quality of surface water where it first appears from the ground water system in each of
the major draws surrounding the site; and,
• Quality of stream sediment in areas where sedimentation is most likely to occur.
These objectives can be achieved through a phased data coUection program involving additional
field methods, upgrading the monitoring network and additional sampling and testing. In
developing this Plan, we have reviewed existing files containing background infonnation and
previous recommendations made by others involved in this project. Pertinent information has
been incorporated into this Plan. The data collection program is recommended as follows:
Phase l, Data Collection:
Phase 1 data collection is needed to comply with the regulatory requirements and to obtain
current data for planning Phase 2 activities. Phase 1 generally involves sampling and analyses of
surface water and sediment from existing stations and several additional locations (Figure l ). All
sampling and testing procedures should he conducted in accordance with the existing Sampling
Plan (attached). The following sampling and analyses are recommended:
l. Repeat the first round (July, 1994) for all existing locations and corresponding matrices
(see Table 1) excluding soil samples collected on the landfill cap and monitor wells.
✓ 2. Two (2) surface soil samples taken in the northern settling basin.
3. · Six (6) sediment samples along Rich.neck Creek and the unnamed tributary in depositional
prone areas and as close to the landfill as possible.

',
4. Four (4) surface water samples, o~~-'from each of the major draws and as cl?se to the
landfill as possible. The sample should be collected from the first occurrence ot water.
Phase 2 Data Collection;
Phase 2 work primarily involves collecting additional information to further understand the site
hydrogeology and possible plume movement. This will involve the use of surface geophysical
methods, a drilling and sampling program, monitor well installations and additional soil and water
laboratory analyses as described below:
Surface Geophysical Program -It is recommended that a combination of electomagnetic and
seismic surveys be used in the vicinity of the landfill (Figure 2). These techniques may be useful
for further defining:
• Geologic characterization (top of rock, fractures and faults, lithologic correlation, and
clay confining layer mapping);
• Hydrogeologic characterization (water table mapping, aquifer thickness, confining layer
continuity);
• Plume delineatioQ (soil/groundwater contamination);
• Anamolous areas in the landfill; and,
• Possible locations and depths of additional borings and wells.
Drilling and Sampling Programing -The environmental drilling and sampling program should
include collection and testing the in-situ soil and ground water and installing monitor wells to
better define the ground water flow direction. These data will be used to detect if leaks have
occurred from the landfill as well as planning locations and depths of permanent monitor wells.
At this time it is assumed that at least one monitoring cluster will be located at each draw, as also
reflected in Figure 1.
Environmental technologies such as Push Probe and Hydropunch are recommended to obtain
vertical distribution of soil and ground water quality. All samples should be handled in
accordance with the attached Sampling Plan. It is anticipated that ten ( 10) borings will be
performed directly adjacent to the landfill as shown in Figure 2. At least one of the borings will
be used as a lithology test boring complete with continuous sampling to. competent rock. Three
soil and two ground water samples will be collected from each boring using in-situ technology.
The soil samples (Figure 3) will be collected from below the base of the landfill and above the
water table in the silty clay strata (about 30 feet deep), within the sandy silt strata (about 50 feet
deep) and within the saprolite zone (about 60-90 feet deep). Ground water samples will be
collected using hydropunch technology at the water tab.le and in the saprolite zone of each boring

It is recommended that both samples be analyzed. However, only one soil sample from each test
boring will be tested.
Currently only four monitor wells exist at this site. Figure 4 shows that the water level in MW-2
is consistently lower than the other wells and that the highest water level varies seasonally in MW-
1, 3 and 4. However, review of the data provided indicates the MW -1 has failed to respond to
changes in water levels since approximately December, 1994 and prior to that consistently lagged
the other wells. This may be the result of a plugged well screen, but underscores the importance
of having a proper well design in order to collect representative environmental data.
Since the landfill lies on a ridg~ crest, ground water is expected to flow radially outward from the
site. In at least four of the new locations drilled (Figure 3) adjacent to the landfill, wells should be
installed to better define the direction of ground water t1ow. These four wells should be surveyed
and static water levels measured in addition to existing well measurements. This information will
be used to better define the water table contours, flow direction and gradient at the site. These
new wells should be screened across the first most productive zone below the water table to
standards described in the following section.
Moniwr Welt Installations
Monitor wells will be designed and located based on site geology results of the Phase I tests,
surface geophysical survey, environmental drilling program and ground water flow direction. It is
recommended that si.x monitor well clusters be constructed to detect the migration of
contaminants based on the potential for enhanced migration. In addition to that basic network
which is outlined in Figures 1 and 2, if contamination is detected in Phase I. Supplemental
locations may be prudent.
Each of the proposed six well clusters would include two wells installed adjacent to one another
and screened at different intervals. Within each cluster one well should be screened at the water
table but to capture the seasonally low water elevation and the other should be screened within
the saprolite zone immediately above the bedrock surface. All new permanent monitor wells
should then be sampled and tested in accordance with the attached Sampling Plan.
Well Construction Guidelines
All field work shall be conducted in conformance with accepted engineering and geologic
practices as well as the Groundwater Section's Guidelines for the Investigation and Remediation
of Soils and Groundwater and the Hazardous Waste Section's Sample Collection Guidance
Document. Well installation shall be in conformance with the North Carolina Well Construction
Standards. A site safety plan shall be developed and followed by all field personnel. AU
appropriate decontamination procedures documented in the references above shall be followed.
During the installation of each boring/well, a qualified hydrogeologist shall be present and a
~oring log completed for each well. Split spoon samples shall be col.lected at each change in
lithology and where there has been a significant change in the penetration/drilling resistance. Soil

cuttings shall be containerized until the analyses of ground water samples have been received from
the laboratory. At such time, the appropriate disposal option shall be selected.
Each well shall be constructed: a) in accordance with the attached diagram; b) in confonnance
with the State's well construction standards: and c) to be capable of yielding a ground water
sample representative of the ground water quality at that location. The well casing and screen
shall be constructed of 2 inch diameter PVC. The manufactured well screen shall be sized
appropriately, according to the soil type. Each well shall be completed with a 10 foot well screen.
The annular space from the bottom of the borehole to a distance of 2 feet above the top of the
well screen shall be filled ,vith an appropriately sized sand pack. A two foot bentonite seal shall
be placed on top of the sand pack. Above the bentonite seal the annular space will be filled with a
bentonite-cement grout. Each well shall be completed with a protective steel outer casing and a
locking cap. A sloping pad shall be constructed around the base of the well in order to direct
water away from the well.
Upon completion of the well, a water level measuring point shall be established and the elevation
detennined to the nearest O. 01 foot.
Each monitoring well shall be developed after the seal and grout have stabilized and no sooner
than 24 hours after completion of the well. The well shall be developed until all suspended
materials are removed or a reasonable volume of water has been removed. All well development
and purge water shall be containerized until the analyses of ground water samples has been
received from the laboratory. At such time, the appropriate disposal option shall be selected.
After all wells are completed, hydraulic conductivity value(s) will be developed for the aquifer. A
minimum of six slug tests or one pumping test shall be performed in order to develop the
hydraulic conductivity value(s) at selected permeable zones. The specific wells to be used in the
aquifer testing shall be selected after an evaluation of the soil sample descriptions has been
completed.
Summarv Repon
At the conclusion of the field work a data summary report will be prepared. The report shall
concisely summarize methodologies employed and results of activities including Phase I sampling
and testing, srn:face geophysical surveys, environmental drilling program, permanent monitor well
placement and construction, hydraulic testing and analysis, and soil and water quality. Essential
text, graphs, tables and figures will be inc.luded in the report.

MEMORANDUM
To: Bill Meyer
From: Bob Glaser, Grover Nicholson, Larry Rose, and Pete Doorn
RE: Proposed Sampling for the PCB Landfill
In the June 7, 1996 meeting, we were provided with a May 28, 1996 memoranda and a June
4, 1996 letter from the PCB Landfill Working Group's (Working Group) Science Advisor,
Patrick Barnes. These documents set out a specific sampling program for the landfill .
After reviewing these documents, we are proposing an alternative sampling program. We
believe this program addresses each of the concerns of Mr.Barnes. The major differences in
the two programs are: 1) the sequence of activities; 2) the use of site specific ground water
data in the selection of proposed sampling locations; and 3) the proximity of the additional
monitoring wells to the landfill. We believe our proposal describes a sound scientific
approach to address each of the potential contaminant pathways. Eventhough cost was not a
factor in our proposal, we believe this program is more cost effective also.
We recommend that our proposal be reviewed/edited by the appropriate staff and submitted to
Mr. Barnes as an alternative to his proposal. We believe that our proposal or some "hybrid"
proposal (combination of his and our proposal) may be agreeable to Mr. Barnes. Since Bob
Glaser has contacted Mr. Barnes earlier and discussed Mr Barne's proposal in detail , Bob may
be the appropriate individual to submit the alternate proposal.
GOALS:
NORTH CAROLINA DIVISION OF WASTE MANAGEMENT
PROPOSED PCB LANDFILL SAMPLING PROGRAM
The goal of sampling program proposed by the Division of Waste Management (DWM) staff
is to address each of the potential contaminant migration pathways for the contaminants of
concern at the PCB landfill. Each of these migration pathways were considered in Mr Barne' s
proposal. The potential migration pathways are: 1) ground water and 2) overland runoff of
PCB contaminated media during the filling of the landfill.
SAMPLING PROGRAM:
The DWM proposes the following activities, in two phases, to accomplish the goals of the
sampling program.
PHASE I:
The initial phase of the sampling program would be to identify the potential water
quality sample locations considering ground water as the transport mechanism. The
first field activity would be to establish additional ground water monitoring stations
(wells) in order to collect ground water surface elevations. These same wells would be
suitable for the collection of ground water quality samples in the second phase of the
program. The specific locations for the additional wells are identified on the attached
figure We believe ground water surface elevation and hydraulic head data from these
wells will provide sufficient data to construct a ground water flow net for the area
surrounding the landfill. The flow net will illustrate ground water flow in both plan
view and cross section. With the flow net and the approximate locations of the ground
water seeps (ground water discharge points) on the 7 .5 minute USGS quadrangle sheet,
we believe that the appropriate surface water quality and ground water quality sample
locations could be selected.
PHASE II:
The second phase of the sampling program would be to identify and sample each of the
appropriate locations upgradient and downgradient of the landfill. These sample
locations would include both the water quality sample locations and the sediment
sample locations. Specific sample locations would be selected after considering the
data collected in PHASE I. The specific parameter list would include each of the
constituents agreed upon by the Working Group and the DWM.
Both ground and surface water quality sample locations would be selected after
considering the ground water flow net and the ground water discharge locations. All of
the wells hydraulically downgradient of the landfill would be sampled. Downgradient
.. '
surface water sample locations would also be included. Surface water sample locations
would include each of the ground water seeps hydraulically downgradient of the landfill
as well as several locations from the perennial stream downstream of the seeps. As a
quality control measure, both upgradient surface and ground water samples would be
collected.
Stream sediment sample locations would be identified after considering the surface
water sample locations and a topographic map of the landfill and surrounding area.
Overland flow is the potential transport mechanism for potential contamination at these
loctttions, These loctttions would most likely be consistent with those proposed by Mr.
Barnes.

Warren County PCB Landfill Investigation Plan
1. The purpose of the plan is to determine if there has been a release of contaminants from
the landfill.
a. Since the landfill was constructed as a disposal of PCB-contaminated soils,
the primary contaminant of concern is PCB.
b. Other contaminants of concern are dioxins and furans, which are
sometimes associatedwith PCBs, and volatile and semi-volatile organics,
and inorganics.
2. Contaminants may migrate from the landfill via air, surfacewater, and ground water.
a. Possible air releases of VOCs and methane are restricted by the synthetic
landfill cap, and would be directed out of the landfill at the vent.
b. Releases to surrounding soil and surface water via runoff from the landfill
are highly unlikely because the landfill is capped, because there were no
stockpiles of PCB-laden soil during filling of the landfill, and because PCB-
laden soils were placed directly into the lined excavation. The only
conceivable release to surface water and sediment that could have occurred
is through contaminant movement into the ground water and thence into
surface water at discharge areas (seeps and streams).
c. The main pathway of concern for a release from the landfill is ground
water. It is conceivable that, through a breach in the landfill liner system,
contaminants could move into the underlying ground water.
3. The investigation should concentrate first on detection of a release from the landfill to the
ground water. The investigation should seek to define the localized ground water flow
pattern.
a. Considerable geologic and hydrogeologic information is available about the
landfill site. The bedrock in the area consists of Cambrian gneiss and
schist, which is fractured, and which is overlain by saprolite and residuum.
The water-filled fractures in the bedrock and pore spaces in the saprolite
and residuum act as a single unconfined aquifer below the top of the zone
of saturation.
b. The landfill lies alongside a topographic high, and hydrogeologic principles
say that the ground water flow in this unconfined condition is away from
the landfill and toward the surrounding streams, and that the water table
surface is probably a subdued reflection of the surface topography.
c. Most likely, ground water flows from the recharge area at the top of the
hill, beneath the landfill, toward the draws to the north, northwest, south,
and southeast, and discharges into the streams and, in times of high
recharge, into the intermittent streams around the landfill.
d. In this type ofhydrogeologic setting, mobile contaminants from a breach in
the landfill liner system would migrate vertically until they encountered the
ground water table, and then follow the flow paths toward the discharge
areas.

SUBJECT: Sampling of PCB Landfill
JUN O 31996
I appreciate your effort in the sampling of the PCB Landfill. The Working Group has
hired a new contractor, Patrick Barnes, to evaluate environmental conditions at the landfill.
Patrick is a PG. and has spent several days on the site to determine sampling locations and
parameters. He has requested that the division implement a phased approach at the landfill. I am
enclosing a copy of Patrick's proposal. The sampling event should commence within the next
three weeks.
The previous sampling event was accomplished by three teams of two to three members
each. I assume that the same process is appropriate for this sampling event. T earn members from
Superfund included: Grover Nicholson, Harry Zinn, Bob Harding; Hazardous Waste -Pete
Doorn, Gray Stephens, Tom Walker, Surabhi Shah; Solid Waste -Larry Rose and Mark
Poindexter. Larry Rose served as the project team leader. Pat Williamson will serve as project
facilitator for the division. I would appreciate your consideration for supporting this effort. The
team needs to meet this week to outline specific responsibilities. I have asked that Larry Rose
continue in his role as team leader. Please contact Larry with your appointment to the team as
soon as possible.

SUBJECT: IDJplementation of Phase I Supplemental Environmental Sampling
at the PCB Landfill
As we agreed, the analytes, QA/QC and Health and Safety procedures for the existing Field
Sampling Plan are acceptable for fi.tture sampling activities. Several additional sampling locations;
however, should be added for a more comprehensive evaluation. I would recommend a phased
approach for the next group of samples. We are in the process of preparing a Phase l sample
location map and a supplement to the existing plan. Proposed Phase I sampling would include the
following:
1. Repeat first round sampling and analysis for all locations and corresponding matrices
excluding soil samples collected on the landfill cap and monitor wells,
2. Su1face soil samples in the northern settling basin.
3. A total of six (6) soils sediment samples, one from each of the major draws surrounding
the site.
4. A total of five (5) sediment samples located in sedimentation prone areas along Richneck
Creek and the unnamed tribtttary. ·
5 A total of six (6) surface water samples, one from each of the major draws as close to the
landfill as possible (if water is present).
Proposed Phase II sampling will involve the following:
l . Hydropunch technology will be used to collect groundwater samples directly adjacent to
the toe cf the landfill. The hydropunch data will be used to identify if leaks may have
occurred as well as the vertical distribution of water quality.
2. Permanent monitor wells will be designed and located based on results of the hydropunch
data. At a minimum, one monitor well cluster should be placed uphill from each of the
draws.

SUPPLEMENTAL SITE INVESTIGATION PLAN
1.0 Background

(""7) ([,:\ D . J ,; I '] : r I i . "\j ; . I lJ
The State of North Carolina owns and maintains a closed landfill containing PCB-contaminated
soils_ This landfill is permitted under the Toxics Substances Control Act (TSCA)_ This landfill is
vinyl and clay lined and contains approximately 40,000 cubic yards of soils (24 feet thick)
contarninated with polychlorinated biphenyls (PCBs). The landfill is located on a 142~acre tract
ofland located just off State Road 1604 in Warren County. the containment area or landfill cell is
enclosed by a fence occupying approximately 3. 8 acres (Figure 1 ).
2.0 Purpose
Barnes, Ferland and Associates, Inc. (BFA) has developed the following "Supplemental Site
Investigation Plan" (Plan) to acquire more detailed information for detennining the environmental
impact associated with the landfill and for planning the scope of the remedial design program.
The objectives of this Plan are to determine the:
• Geological setting including definition of soil and rock types, permeable and confining
layers, fractures and faults, hydraulic properties and potential contamination pathways;
• Direction and rate of groundwater and surface water flows and seasonal water table
variations;
• Location and extent (both vertical and horizontal) of soil and groundwater contamination
at discrete intervals;
• Quality of surtace water where it first appears from the ground water system in each of
the major draws sutTounding the site; and,
• Quality of stream .sediment in areas where sedimentation is most likely to occur.
These objectives can be achieved through a phased data collection program involving upgrading
the monitoring network, additional sampling and testing, and surficial geophysics if required .
In Februar/, 1995 the State developed a proposal to update the existing groundwater monitoring
net\vork by installing three deep monitoring wells and one additional shallow monitoring well In
October of 1995 the plan was reviewed by George Bain, P.G., who also recommended additional
spatial coverage both in shallow and deep zones. Mr. Rain's review also emphasized the difficulty
of developing a groundwater monitoring system to detect the migration of contaminants in
fractured rock.

We agree with the recommendations of both the State and Mc Bain, and have incorporated their
concerns into the scope of this investigation.
3.0 Site Setting and Hydrogeology
The J 42 acre site is near the nose of a NE trending ridge, whose general elevations are greater
than JJO feet (NGVD). Part of the approximately 4-acre fill area are \vi thin the 340 feet (NGVD)
contour \vhich forms a small local closed high on the nose CJf the ridge. Su1face drainage to
Richneck Creek to the N\V/N/N.E and E and to an unnamed tributary to the SISE.
The site is underlain by a related sequence of mica schists, according to the North Carolina
Geological Survey and the USGS report "Geology and Ground-Water Resources in the Raleigh
. .t\rea, NC''. Rocks that compose this complex of mica schists exhibit layering, but attitude and
composition of individual zones cannot be observed in the site area because of deep weathering.
Data from auger ho.les at the site indicate the following general sequence of weathered strata:
Land surface to l 0-20 feet -Red-brown micaceous fine sandy clay; 10-20 feet to bottom of hole
(rnax depth about 40 feet) -Brown micaceous sandy clay to sandy silt to clayey.
The above materials are thoroughly decomposed native rock; formed in place by chemical
weathering and characterized by preservation of structures that were present in the unweathered
rock. These materials are also referred to as "residual soils".
The exact depth to partially weathered rock or to fresh bedrock is not known at the site. Partially
weathered rock, as used herein, refers to the zone between thorough.ly weathered residual soils
above to fresh bedrock below. The term saprolite is often applied to this zone. For the sake of
consistency with other documents prepared for this landfill, we have also used the tem1 saprolitc
to refer to that zone . Permeability in saprolite zone has been enhanced by fracture/weathering
processes, and it is commonly the most permeable zone in the vertical section. This enhanced
permeability is oflen exploited by seating well casing within or immediately below the partially
weathered zone. The water table commonly occurs io the overlying residual soils but may occur
or fluctuate within the saprolite. Because of its higher transmissivity, this zone should be
considered an avenue to transmit contaminants
The natural water table in this area should be a subdued expression of the surface topography;
that is, mounded under the ridge with highest gradients toward the topographically iow areas in
general N and S directions and lower gradients to the E/NE. Height of this mound, which
represents the water table, would depend on such factors as vertical and lateral permeability of the
residual soils/saprolitic materials; distance to points of natural discharge; and duration and
magnitude of recharge events. A smaller mound related to the closed 340 feet contour may occur
under part of the site area.
Recharge to the mound, or groundwater reservoir, occurs by downward infiltration through the
unsaturated zone to the water table, where the infiltrating fluid becomes groundwater. General
circulation of groundwater in this environment is downward from the water table to the zone of
partially weathered bedrock, then laterally to points of areas of eventual discharge (usually

streams or springs under natural conditions), Deeper circulation below the partially weathered
zone is usually limited by rapidly decreasing occurrence of interconnected fractures with depth in
underlying fresh bedrock. Thus the most commonly expected groundwater flow path is
predominately downward from the water table to the saprolite zone, then predominantly in the
lateral direction to discharge areas. Discharge has been observed as would be expected emerging
from the walls of the major draws in the saprolite zone . Deviations in this idealized flow path may
occur re.lated to inhomogeneities in the residual soils. In layered strata, as an example, difference~
in permeability may result in lateral flow components beginning to predominate above the
saprolite zone, thus resulting in shortening the groundwater flow path and discharge to contact
springs on the adjacent valley wall above the panially weathered rock.
Thus, in summation, this is a very localized groundwater flow system in that all recharge to the
mound underlying the ridge occurs from infiltration from the ridge. and most discharge occurs t.o
adjacent valleys of Richneck Creek and its unnamed tributary. Deep circulation wi thin the
bedrock to eventual discharge in more distant areas is not expected. The most probable flow path
for ground\vater is downward to the partially weathered zone, then predominantly in lateral
direction to the nearby discharge areas. This idealized flow path may be, in part short circuited
by inhomogeneities in the materials above the panially weathered zone, in which case discharge
would occur at higher elevations in the adjacent valleys.

Jt is important that some continuity with the previous analysis be maintained to establish
trends whenever possible. The establishment of trends is critical to our ability to determine
the real potential threat associated with migration of contaminants. It is particularly
important that locations which tested above detection .levels be reanalyzed . Repeat the first
round (July, 1994) for all locations and corresponding n:1atrices (see Table 1) excluding soil
samples collected on the landfill cap, which correspond to the landfill system
These locations include the leachate inlet and outlet, the settling pond overflow pipe base,
soil at the center of the pond and the discharge pipe outlet. A sample of the landfill come ms
will also be collected from the central gas vent . It is particularly important to continue to
regularly analyze the landfill contents, which will enable continued evaluation of natural
biodegradation.
Procedures to be followed in the collection of those samples outlined are in Appendix A.
Fu rt.her analysis of landfill cap materials is not warranted because it was properly addressed
previously and there is no mechanism for it to be contaminated. Reanalysis of 1\1\V-1 is not
recommended because the well screens appear to be plugged . This is discussed in more
detail later.

5.2.1 Locations
Two additional deep groundwater samples from wells adjacent to MW-3 and MW-4 .
These wells will yield samples from the weathered rock (saprolite) zone. These wells
which will be designated MW-3A and 3B are important. to establish the vertical flow
component at key existing locations. The new hydraulic and groundwater quality data
will be conlpared to that of the ex_isti11g wells at those locations Comparison of these
data will give us an indication of the relative transmissivity of each zone and how much of
the recent recharge reaches the saprolite zone.
\Vater table and ~aprolite zone groundwater samples will also be obtained at locations
directly northwest, south and east of the landfill within 25 feet of the landfill footprint.
These three clusters of wells which will be designated MW-1 A, B, MW-5 A, B and MW-7,
7 A are critical to the establishment of a proper flow net for the immediate vicinity of the
landfill. They \,Vill also yield key water quality data from areas directly adjacent to the
landfill in the currently aoticipated flow paths.
Groundwater samples will also be coUected in the three major draws located to the north,
northeast and northwest of the landfill and in the one major draw located to the
southeast.

As discussed in Site Hydrogeology, it is very difficult, if not impossible, to develop a
monitoring network which will capture l 00% of the flow in a fractured rock system
These four wells are positioned to minimize the guess work. The orientation of the draw
features which surround the site is dictated by fractures (see Figure __ ). Enhanced
directional groundwater flow will occur along these fractures . By locating monitoring
wells within these features we have an extremely high probability of detecting
groundwater flow as it leaves the landfill site,
Of the seven draw features identified on Figure __ , it appears that five intersect the filled
area. Because of the uncertainty of flow patterns leading to these draws, it is important
that they be monitored with wells located at approximately the 300 fl. to 3 l O ft.
elevation. Proposed monitoring wells MVl-6. l\1\V-8, MW-9 and MW-10 are positioned
to intercept groundwater flow along these features .
With the exception of VOCs. surface water collected within these draw features should
have the same quality characteristics as that of the groundwater; however, the monitoring
wells are needed so that samples may still be collected during low flow periods.
Background groundwater samples from three wells located out.side of the landfill
groundwater and surface water flow system are also proposed . At least one of these
wells will be screened at the \vater table. The other two will be screened within the
saprolite zone . The wells will be designated BG-l , 2 and 3. These background wells will
enable proper technical review of data collected at the remaining locations. by allowing
us to filter out the cont aminants which might exist within the groundwater outside of the
influences of the landfill .
Monitoring well sample collection procedures are outlined in Appendix A.
5.2.2 Drilling Procedures
The environmental drilling will be accomplished by the Hollow Stem Auger drilling
method. Soil samples will be collected using split spoon samplers. All samples will be
handled in accordance with Appendix A
It is anticipated that nine (9) borings will be performed; one at each proposed well
location. At least four of the borings will be used as a lithology test boring, complete
with continuous sampling to competent rock. The soil will be closely classified to
identify geologic, not engineering, properties. The soil samples from the test boring at
locations l , 5 and 7 (Figure 3) will be collected frorn below the base of the landfill and
above the water table in the silty clay strata (about 30 feet deep), within the sandy silt
strata (about 50 feet deep) and within the saprolite zone (about 60-90 feet deep). Soil
will be collected in the remaining five borings at five-feet intervals or change in lithology.
It is recommended one soil sample from each test boring will be analyzed . All auger
flights and split spoons will be thoroughly decontaminated before use and between
borings.

5.2.3 Monitoring Well Desi~rn/Testing Procedures
Currently only four monitor wells exist at this site. Fif,'llre 4 shows that the water level in
MW-2 is consistently lower than the other wells and that the highest water level varies
seasonally in MW-1, 3 and 4. However, review of the data provided indicates the MW-l
has failed to respond to changes in water levels since approximately December, 1994 and
prior to that consistently lagged the other wells . This may be the result of a plugged well
screen, but underscores the importance of having a proper weU design in order to collect
representative environmental data.
Since the landfill lies on a ridge crest, ground water is expected to flow radially outward
from the site. All of the proposed wells will assist better defining the direction of ground
water flow. They will be surveyed and static water levels measured in addition to
existing well rncasurernents. This information will be used to better define the water table
contours, flow direction and gradient at the site .
Each of the proposed well clusters would include two wells installed adjacent to one
another and screened at different intervals. Within each cluster one well should be
screened at the water table but to capture the seasonally low water elevation and the
other should be screened within the saprolite zone immediately above the bedrock
surface. AJI new permanent monitor wells should then be sampled and tested in
accordance ,:vith the attached Sampling Plan .
:\11 field work shall be conducted in conformance with accepted engineering and geologic
practices as well as the Groundwater Section's Guidelines for the Investigation and
Remediation of Soils and Groundwater and the Hazardous Waste Section's Sample
Collection Guidance Document. Well installation shall be in conformance with the North
Carolina Well Construction Standards. A site safety plan shall be developed and
followed by all field personnel. All appropriate decontamination procedures documented
in the references above shall be followed .
During the installation of each boring/well. a qualified hydrogeologist shall be present and
a boring log cornp.leted for each well Split spoon samples shall be collected at each
change in lithology and where there has been a significant change in the
penetration/drilling resistance. Soil cuttings shall be containerized until the analyses of
ground water samples have been received from the laboratory. At such time, the
appropriate disposal option sha.11 be selected.
Each well shall be constructed: a) in accordance with the attached diagram; b) in
conformance with the State's well construction standards; and c) to be capable of
yielding a ground water sample representative of the ground water quality at that
location. The well casing and screen shall be constructed of 2 inch diameter PVC. The
manufactured well screen shall be sized appropriately, according to the soil type. Each
well shall be completed with a 10 foot well screen. The annular space from the bottom of

SUBJECT: Implementation of Phase I Supplemental Environmental Sampling
at the PCB Landfill
As we agreed, the analytes, QA/QC and Health and Safety procedures for the existing Field
Sampling Plan are acceptable for foture sampling activities . Severa! additional sampling locations:
tiowever, should be added for a more comprehensive evaluation. I would recommend a phased
approach for the next group of samples. We are in the process of preparing a Phase l sample
location map and a supplement to the existing plan. Proposed Phase I sampling would include the
follov.--ing:
1. Repeat first round sampling and analysis for all locations and corresponding matrices
excluding soil samples collected on the landfill cap and monitor wells .
SLttface soil samples in the northern settling basin.
:3. A total of six (6) soi.ls sediment samples, one from each of the major draws surrounding
the site.
4 A total of five (5) sediment samples located in sedimentation prone areas along Richneck
Creek and the unnamed tribLttary.
5 A total of six (6) surface water samples, one from each of the major draws as close to the
landfill as possible (if water is present).
Proposed Phase U sampling will involve the following:
l. Hydropunch technolo~ry will be used to collect groundwater samples directly adjacent to
the toe of the landfill The hydropunch data will be used to identify if leaks mav have
,.,
occurred as well as the vertical distribution of water quality. · ·
Pem1ancnt monitor wells will be designed and located based on results of the hydropunch
data. At a minimum, one monitor well cluster should be placed uphill from each of the
draws.

3. Groundwater samples will be collected and tested from each of the monitor wells.
We are in the process of reviewing the previously proposed, expanded groundwater monitoring
plan and will incorporate its recommendations into our Phase II supplement. It is recommended
that the State move quickly with the Phase I sampling activities. A Phase I supplement should be
submitted to your office by June 7 ~ 1996.

SVBJECT: Coordination of and Responsihilities for Sampling and Testing Activities
Dear Bill .
Relative to the abcwe I understand the following :
• The State v.-ill assemble a team of samplers who will collect environmental samples in a
phased approach as outlined in our memo dated May 28 , 1996.
• The field team leader will closely coordinate all acti\,ities with the Science Advisor
• The sampling activities will be in accordance with the existing Sampling Plan and our
proposed supplement
• Approximately 15%1 of samples will be split with the Science Advisor and analyzed by a
fully qualified but independent laboratory
• Bf A will provide a location map containing all proposed sampling points .
• The State will advise me as to whether or not it can make available all terrain drilling
equipment and when.
Other issues which have resulted from two recent attempts to field verify proposed off-site
sampling locations are:
• The potential need to coordinate with and/or obtain easements from adjacent property
owners.
0 The need to perfonn clearing and grubbing activities such that the samplers can easily
access each sample station.

At this time it is assumed that these activities will be performed by the State. Please notif)· me if
you recommend otherwise.
Attached is a draft map of the proposed sample locations. Several of these locations have alreadv
been verified and flagged. Substantial clearing will be required to access sites to the west of the
landfill . Larry Rose of your department is very familiar with the procedure being used to identi~.
surface water, sediment and groundwater sample locations. If the State is to arrange for and
contract the necessary clearing acfr. .... ities. it is recommended that. if possible, he be involved in
that process.

Special Decontamination Procedures
Warren County PCB Landfill
On June 13, 1996 I talked to Debbie Hague of Triangle
Laboratories (544-5729 ext. 270) concerning any special procedures
necessary when collecting samples to be run for Dioxins by Method
8290. She informed me that they will supply the containers and the
rinsate water, amber jars will be used where possible, and paper and
plastic should be kept away from the samples.
On June 14, 1996 I talked to Mr. Bill Bokie of the US EPA Region
IV Environmental Services Division. Mr. Bokie stated that ESD does
not use any special decontamination procedures or sample collection
procedures in connection with these types of samples. Past sample
data has shown that the current procedures are adequate to eliminate
the potential for outside contamination of the samples with dioxins,
PCB's, or furans.

on Landfill
Site History:
Between June, 1978 and August, 1978, roughly 30,000 gallons of industrial waste material
identified as PCBs (Arochlor 1260 and 1262) were discharged deliberately along the shoulders of
approximately 150 miles of NC Highways. In June, 1979, EPA approved a tract ofland
(previously used for agriculture) in Warren County as the disposal site for the PCB-contaminated
roadside material. The landfill (constructed in 1983-1984 and permitted under the Toxic
Substance Control Act (TSCA) contains about 40,000 cubic yards of soil contaminated with
PCBs. The concentration of PCBs in the landfill ranges from 0-3 IOppm.
C. SITE HAZARD EVALUATION
Based on past sampling results, the cap of the landfill does not contain any substantial amount of
PCBs. Samples of the leachate from the pond-outlet, near outlet, middle, filter 1 and 2-on the
northside of the landfill showed to have between <O. IOppm, <O. IOppm, 0.53ppm, 1.15ppm,
1.45ppm respectively.
Samples from inside the landfill (retrieved from the bottom of vent pipe on top oflandfill) consists
of wet and dry contents and were found to contain 151.8ppm and 301.4ppm PCB respectively.
Soil samples from the est side oflandfill (along the side) found to contain 0.22ppm PCB, this was
to measure runoff.

FIELD SAMPLING PLAN
FOR WARREN COUNTY PCB LANDFILL
Draft Draft
July 12, 1 994
Prepared for
Draft
Joint Warren County and State PCB Working Group
by
North Carolina Department of Environment, Health, and Natural
Resources
Division of Solid Waste Management
FIELD SAMPLING OVERVIEW
TEAM ORGANIZATION
All field efforts by staff of the Division of Solid Waste Management or
its contractors will be lead by the Site Manager of the field effort. A Site
Safety Officer will be appointed by the Director of the Division and will be
independent of the direction of the site manager.
The field team, reporting to the site manager, will consist of adequate
numbers of staff to safely complete all required field sampling, labeling, and
reporting tasks in an efficient manner. Individual members of the field team
will coordinate with the disciplinary task leader developing the methodologies
and protocols for the field sampling and analysis effort. These disciplines
include:
Environmental chemistry
Environmental engineering
Hydrogeology
Environmental toxicology
Environmental statistics
Analytical chemistry
OVERSIGHT
The Science Advisor to the Joint Warren County and State PCB
Landfill Working Group or her staff will be allowed to directly oversee all field
activities of the Division of Solid Waste Management or its contractors at the
field sampling effort upon the following qualifications: All such oversight
individuals must be currently trained by 40-hour OSHA hazardous waste
worker standards and must attend a site safety briefing held by the Site
Safety Officer prior to field activities.
SITE SAFETY
A site safety plan has been prepared for this sampling and analysis
event. All individuals present during this effort as team members, oversight
personnel, or observers will be required to adhere to the requirements of this
plan. The Site Safety Officer will be the authority for the site safety plan's
implementation. This authority is separate from the authority of the team
manager, who has the overall field sampling plan responsibility.
PUBLIC AND MEDIA OBSERVATION
Members of the Working Group, the public, and media representatives
are invited to observe the field sampling activities provided they observe
established safety requirements. All observers to the site with the exception
of the Science advisor or her properly trained staff must be accompanied at
all times while on the property.
The Site Safety Officer will establish a zone for each sampling activity
where only properly trained professionals will be allowed to enter. However,
these areas are expected to be small and will be temporary during actual
preparation and sampling efforts. Safe zones will be established where
interested members of the Working Group or other citizens or their
representatives will be allowed to observe the field work.
The work plan calls for a video tape of the sampling effort to be made.
This tape will be made available upon request.
All observers present during the sampling program within the landfill
area (beyond the locked cross wire on the access road to the landfill) will be
required to attend a site safety briefing, sign a statement that they have
received this instruction, and must obey the directions of the site safety
officer and their escort. Observers present during the sampling are required
to be properly attired, including long-sleeved shirts, long pants, and sturdy
shoes (e.g. work boots, hiking boots, or athletic shoes). Chemical protective
overboots will be provided upon request. Any deviation from required attire
will be allowed solely at the discretion of the site safety officer.
METHODS AND PROTOCOLS
The Division of Solid Waste Management uses standard forms and
number-controlled, unique sample labels in all field sampling events. Samples
of these forms and labels follow this section of the Field Plan. Included are:
1 . Chain of custody record -this form accompanies all samples from the
time they are placed in the container and labeled through shipment to
the laboratory and finally accompany the data from the laboratory back
to the requesting authority .. This "chain-of custody" record, where
each subsequent handler of the sample or data acknowledges custody
and reponsibility for the sample is a high-order quality control
procedure. While originally designed for enforcement related samples
that could be involved in court procedings, it has proven valuable in all
areas of quality control.
:z
2. Sample analysis request -this form accompanies samples from the
field to the laboratory. It lists individual samples uniquely by listing the
unique sample identification number from the sample label and directs
the analytical laboratory to perform the appropriate analysis on each
sample.
3. Receipt of samples form -this form is used when the original
sampling team releases split, duplicate, or original samples to another
person or group. This form will be used in this field sampling exercise
when split or duplicate samples are relenquished to the science
advisor.
4. Examples of two field sampling labels have been attached to a page
for demonstration. These labels have distinct computer generated
identification numbers which aids in quality control and field
effeciency. Separate label systems exist for samples to be analyzed
for organic constituents and those to be analyzed for inorganic
constituents.
To the extent practical all methods and protocols used during the
Warren County PCB Landfill environmental characterization will be published
protocols or standards, or modifications of such necessary for the specific
conditions of this effort. In general, all planned field sampling activities and
subsequent chemical analyses follow or are derived from:
U. S. Environmental Protection Agency, 1991, Environmental Compliance
Branch Standard Operating Procedures and Quality Assurance Manual.
N.C. Department of Environment, Health, and Natural Resources, Division of
Solid Waste Management, 1993, Sample Collection Guidance Document.
Occupational Safety and Health Administration Directorate of Technical
Support. 1990. Instruction CPL 2-2.20B CH-1, Chapter 1 Personal Sampling
for Air Contaminants.
U. S. Environmental Protection Agency Office of Solid Waste. 1994. SW-
846. Test Methods for Evaluating Solid Waste Physical Chemical Methods.
Sampling and analysis methods not modelled after the above published
methods are considered survey or research methods and will be used in
addition to, not in replacement of, published methods, where applicable.
All sampling and analysis of samples will be conducted under standard
chain-of-custody methods of the Division of Solid Waste Management, which
comply with all federal environmental regulatory requirements .

LANDFILL CONTENT SAMPLES
PURPOSE
• Collect samples of contents of Warren County PCB Landfill to determine
chemical content of all PCB isomers, dioxin and di-benzo furan isomers,
general organic chemical scans for volatile and semi-volatile organic
contaminants, toxic metals, and the Toxicity Characteristic Leaching
Procedure (TCLP).
• Collect samples of landfill contents for analysis of physical soil
characteristics and nutrient availability
• Determine water level within landfill
• Collect and analyze sample of gases within the landfill
• Construct a temporary water level sampling system through the air vent
• Establish gas sampling port, to support any future sampling, during
reconstruction of air vent.
FIELD SAMPLING METHOD
Following collection of a preliminary air (gas) sample from within the landfill,
the Schedule 40 4" PVC air-vent pipe will be cut off just above ground level.
The gas sample will be acquired using a Gilliam personal air sampling pump,
collected a known volume of gases from within the landfill through a
specialized air sample filter containing charcoal as a collection media. Landfill
content (soil) samples will be acquired by all terrain vehicle (A TV) mounted
with a 1" hydraulic Geoprobe sampling device ("Scorpion") and/or hand
auger. Three or more continuous soil column samples will be acquired first.
These samples will be sleeved in PET plastic tubes. Subsamples from these
columns will be directed for chemical analysis. Additional bulk landfill
content samples will be aquired by Geoprobe or hand auger and will be
directed for the bulk physical analyses.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
All samples will be taken at or within the central air vent for the landfill. A
schematic drawing of this unit is included with this description.
SAMPLING PERSONNEL REQUIREMENTS
Air sampling and site preparation will occur one day before the major field
sampling exercise. A minimum of two, 40-hour OSHA-trained field staff will
be required. On the main sampling day, in addition to the two operators of
the Scorpion-Geoprobe unit, two 40-hour OSHA-trained field staff will be
required for sample preparation, recordkeeping, and general field support
activities.
FIELD EQUIPMENT REQUIRED
In addition to the ATV-mounted Geoprobe sampler and hand augers, field
equipment will include an array of chemically-clean sample containers and
sample collection and preparation devices for handling both soil and water
samples. Sample containers, labels, and sample preservation and
storage(transhipment) containers will also be required. Equipment to
decontaminate sampling devices and sample containers will be required to
prevent cross contamination of samples.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHOD( S>
Soil samples of landfill contents will be analyzed for organic volatile
compounds by EPA method 8240; for semi-volative compounds by method
8270; for pesticides and herbicides by methods 8081 and 8141, for PCBs by
method 8081 and for mono-through octa-dioxins by method 8290, and by
method 1311, the Toxicity Characteristic Leaching Procedure (TCLP). It is
also anticipated that the EPA Athens Lab and the GE Lab will conduct
specialized PCB congener determinations in addition to the standard method
8081.
The NC Department of Transportation Soils Lab will analyze a sample of the
landfill contents by their "Quality Test" methods. These tests include:
plasticity index, liquid limit, sieve analysis (particle size distribution), moisture
content, organic content, and permeability.
The NC Department of Agriculture's Agronomic Soils Lab will perform their
"Standard soil test" on another landfill content sample. The parameters to
be reported include: pH (measure of acid/base balance in the soil), weight
per unit volume, percent humic matter (measure of decomposed organic
matter in soil), cation exchange capacity, and soil nutrient analysis (calcium,
sulfur, phosphorus, potassium, and magnesium content).
QUALITY ASSURANCE PLAN (INCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
The Working Group's Scientific Advisor will _be allowed to have a
representative present at all field sampling activities performed during this
effort. In addition, a video tape of these activities will be made and will be
made available to the Working Group and the citizen's of Warren County.1
1 This condition will apply to all elements of this field sampling plan, but will not be repeated
in writing with each program element.
10
. ...
All samples will be labelled using a number controlled unique sample label.
Chain-of-custudy procedures of the Division of Solid Waste Management will
be used on all samples, continuing throughout the sample transport and
chemical analysis steps by all laboratories. An example of DSWM labels,
Chain-of-custody Record, Receipt of Sample, and Sample Analysis Request
Form are included in the overview section of this field sampling plan.1
Field collected samples of the contents of the landfill targeted for PCB
analysis will be duplicated for analysis by the EPA Lab in Athens, GA and GE
Corp Environmental Laboratory in Schnectady, NY. In addition,
duplicate/split sample(s) of up to 25% of landfill content samples will be
prepared for a CLP laboratory selected by the Working Group's scientific
advisor. Sample(s) for dioxin analysis will be prepared. One or more field or
"trip blanks" will be prepared for analysis by the State Health Services Lab.
1 This condition will apply to a·11 elements of this plan, and will not be repeated throughout
the document. ~

MEMORANDUM

Sharon RogersC'()t
David J. Lown ~r
Approximate Thickness of Waste at the Gas Vent
PCB Landfill, Warren county
The thickness of the PCB contaminated waste at the landfill
may vary from 22.5 to 25.5 feet thick. During the sampling of the
waste through the gas vent, I recommend the following:
1) sample runs be reduced to a maximum of six inches
per run at a depth of 24 feet below the top of the
concrete slab at the gas vent; and
2) sampling be stopped when any of the components of
the liner at the base of the landfill are
identified.
The components of the liner that should be identifiable
include, in descending order, the fabric filter, nine inches of
sand, compacted clay. The compacted clay is five feet thick and
overlies one foot of fill and the 30 mil PVC liner. Figure 1 shows
the details of the bottom liner.
The estimated original thickness of the landfill is based on
the drawings that you provided.. Figure 2 is copied from the
drawing labeled "Cross-sections." Table 1 shows the measured
thicknesses of the landfill at the gas-vent slab.
Changes in the thickness of the waste is based on survey data
found in Randy McEl veen' s files on the landfill. The slab may have
settled two to three feet. The data was collected by the Solid
Waste and the Hazardous Waste Sections for the elevation of the
monitoring wells and the concrete slab at the gas vent. This data
is shown in Table 2. The concrete slab at the gas vent and the
four monitoring wells were surveyed after completion of the
landfill. This data is shown on the as-built drawing "Misc.
Details." The concrete slab and the monitoring wells were
resurveyed in 1991 and 1992.
The accuracy of this data is questionable. On the as-built
drawing, the monitoring well elevations are only given to the
nearest foot and what was surveyed at the well (top of casing, top
of concrete slab) is not indicated. The Hazardous Waste and Solid
Waste Section survey data differ by as much as 0.22 feet.
13
Memo
July 5, 1994
Page 2
According to the cross-section the base of the waste (top of
the liner) should be at a depth of 30.5 feet below the concrete
slab. If there has been 3 feet of settlement and compaction, the
base of the waste is at a depth of 27.5 feet below the slab.
Because of the possible inaccuracies of the data, .I recommend that
the sampling interval be reduced beginning at 24 feet below ·the
slab. Regardless of when the sampling interval is reduced, it is
important to always be looking for the liner components.

LANDFILL LEACHATE SAMPLES
PURPOSE
• Collect sample of leachate (liquid content of landfill) from Warren County
PCB Landfill to determine chemical content of PCB isomers, dioxin and di-
benzo furan isomers, general organic chemical scans for volatile and semi-
volatile organic constituents, and toxic metals.
FIELD SAMPLING METHOD
The method used in collecting samples of leachate from the landfill will
follow those used in previous leachate sampling efforts. Use of the sample
sampling method will allow comparison of previously acquired data to the
new information. Sufficient sample will be withdrawn from the leachate
collection system sampling port and from the inlet the the filter system to
conduct the required chemical analyses. In addition, a sample will be drawn
from the outlet from the filter system. A variety of sample sizes and
containers is required. Samples for organic chemical analysis may be filtered,
and .b.Q1h the liquid fraction and the filter media will be submitted for
analysis. This would be necessary with samples with high particulate
content to determine the actual location of any complex organic molecules,
i.e., are they in the water itself or in the solids suspended in the water.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
The leachate collection system engineered into the design of the landfill
includes an access or sampling port located near the pump house on the
north end of the fenced area. A diagram of the sampling port is enclosed.
In addition, the leachate can be sampled from the inlet to the filter system
(as noted in the drawing accompanying the sample plan for the sand and
carbon filter section).
SAMPLING PERSONNEL REQUIREMENTS
Two teams of two hydrogeological sampling personnel will complete this
task along with the sampling of the four monitoring wells during the main
sampling day's efforts.
FIELD EQUIPMENT REQUIRED
Standard, portable field sampling equipment will be required. A variety of
sample bottles will be available to be properly labeled for the required organic
and inorganic analyses. Portable decontamination equipment will also be
employed to prevent any cross-contact with the chemistry from one sample
to another.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHODfSl
Samples will be transferred to the appropriate laboratory under chain of
custody. All samples to be analyzed for organic chemicals will be maintained
at a temperature below 4°C to maintain the organic chemicals in the
sample(required by standard protocol). PCB analysis will be performed by
EPA Method 8081. Dioxin analysis by EPA Method 8290. Other types of
chemicals to be analyzed and their corresponding tests include: volatile
organics (Method 8240), semivolatile organics (Method 8270), pesticides
and herbicides (Method 8081 and 8141), and toxic metals (various
methods).
QUALITY ASSURANCE PLANIINCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
As requested by the science advisor, up to 20% of the individual samples
collected from the leachate system will have duplicates prepared for the
independent verification. A "trip blank" sample container, containing water
that is free of any organic chemicals, will be prepared to accompany the
sample containers during the entire sampling process, transfer to the
laboratory, and through final analysis. This technique is a standard part of
the quality assurance program for these sampling protocols and is routine
practice for the Division field sampling staff.

GROUNDWATER SAMPLES
PURPOSE
• Collect and analyze samples from existing groundwater monitoring wells
adjacent to Warren County PCB Landfill.
• Determine depth (elevation) of ground water in each well at time of
sampling
FIELD SAMPLING METHOD
Standard field methods for sampling of groundwater monitoring wells will be
used. These methods are currently used to perform periodic routine sampling
of the four groundwater monitoring wells around the landfill. Continued use
of the same method enhances data comparability of new with older data.
Briefly, the method entails measuring the water level; purging the well; and
obtaining the groundwater sample. All water levels and well depths are
measured to the nearest 0 .01 ft below the surveyed measuring point (e.g.,
top of casing). Prior to measuring the water levels, non-vented or seal able
well caps should be removed to allow the water level to equilibrate. The
measuring device will be decontaminated between each well by washing
with phosphate-free soap and rinsing thoroughly with organic-free water.
After measuring water levels, the wells are purged to remove stagnant
water. Purging equipment must not compromise sample integrity. When
purging is completed to protocol specifications, the samples for chemical
analysis should be taken as soon as possible and within 24 hours.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
Existing groundwater monitoring wells are located on state property, but
outside the main landfill fence. One well is located in each direction north,
south, east, and west of the landfill and each is visible on the accompanying
air photo by the small individual fence surrounding each well.
SAMPLING PERSONNEL REQUIREMENTS
The two two-person teams assigned to sample the leachate collection
system also should be able to prepare and sample the four groundwater
monitoring wells in the same sampling day.
FIELD EQUIPMENT REQUIRED
Groundwater sampling equipment must be constructed of materials and
properly prepared so as not to compromise the chemical integrity of the
sample. Thus, all collection devices and sample containers must be
composed of Teflon, glass, stainless steel, or Teflon-coated stainless steel.
Separate collection equipment from sample containers must be used. All
equipment must be carefully decontaminated before and between uses.
Duplicate samples, that approximate split samples by alternately filling paired
sample containers, can be prepared as required. True split samples cannot
be prepared because of the risk of lowering measurable levels of any volatile
organic chemicals during any required mixing.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHOD{Sl
Samples will be transferred to the appropriate laboratory under chain of
custody. All samples to be analyzed for organic chemicals will be maintained
at a temperature below 4°C to maintain any organic chemicals in the sample I
(required by standard protocol). PCB analysis by EPA Method-Bi.SO. Othere::-<is'0'6'
types of chemicals to be analyzed and their corresponding tests include:
volatile organics (Method 8240), semivolatile organics (Method 8270),
pesticides and herbicides (Method 8081 and 8141 ), and toxic metals (various
methods).
QUALITY ASSURANCE PLANIINCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
As selected by the science advisor, up to 20% of the individual samples
collected from the groundwater monitoring wells will have duplicates

organic-free water will be prepared to accompany the sample containers
during the entire sampling process, transfer to the laboratory, and through
final chemical analysis. This technique is a standard part of the quality
assurance program for this sampling protocol and is a routine practice of the
Division of Solid Waste field sampling staff.

SURFACE WATER SAMPLES
PURPOSE
• Collect and analyze water and stream sediment samples to determine if
PCB congeners are present.
FIELD SAMPLING METHOD
Standard field methods for collecting samples of flowing water and stream
bottom sediments will be used. Care must be taken to minimize disturbance
of the stream, e.g., downstream samples taken before upstream, water
samples taken before stream bottom sediment samples, and all sample
collection equipment and containers carefully decontaminated by organic-free
methods before and after use. Subject to the amount of flow present in the
stream at the time of sampling, surface water samples are obtained by
standing downstream of the water to be sampled, turning the container
sideways, partially submerging the container allowing water to fill the
container with minimal agitation. Floating debris must be prevented from
entering the sampling container.
Stream substrate samples are collected by forcing a hollow tube into the
sediment to a depth of up to 8 ", followed by capping the tube before
removing it from the sediment, then transferring this collected material to the
sample container that will be sent to the laboratory. This step is repeated
until adequate quantity of sample is acquired. In the event of a rocky or
impenitratable substrate, a glass sample container is used in place of the
sample tube. In this case, substrate is collected by secondary container and
transferred.
Samples will be taken at four locations, two each on the two streams near
the Landfill. To maximize the value of the data, samples will be taken at the
permanently established locations for which considerable comparable data
already exists.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
The four existing stream sampling locations are located on the detailed (large)
Warren County PCB Landfill map that has been provided to the Working
Group and on the enclosed topographic insert.
SAMPLING PERSONNEL REQUIREMENTS
Two individuals will be required to perform this sampling event. The two
hydrogeological sampling personnel will conduct this effort.
FIELD EQUIPMENT REQUIRED
Sample containers, sample collection equipment, and portable
decontamination equipment will be required.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHOD<S>
Stream water samples and sediment samples will be analyzed by EPA <7 /
Method 8290 for PCB content. ?JO D
QUALITY ASSURANCE PLANIINCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
If requested duplicate samples can be prepared, however, true split samples
are impossible due to the organic nature of the samples.

• Collect samples of surface soils around the central air vent of the landfill
to analyze for PCB content.
• Collect samples of surface soils around the leachate collection system
sampling port and pump house to analyze for PCB content.
• Collect surface soil samples from any potentially suspect surface area of
the landfill and analyze for PCB content
FIELD SAMPLING METHOD
Standard soil field sampling methods will be used. Each area targeted for
surface soil sampling will be gridded off in the field. Location _ and number of
samples to be taken will be determined in each area by standard statistical
methods (random sample location selection and Student's T-test verification
of representative number of samples) as approved by EPA for wide area
targeted sampling. At the discretion of the field team manager, radial
quadrants can be developed around each structure and all samples from that
quadrant composited. This is an option because air currents would be the
predicted mode of transport, such that individual quadrants should have
similar exposure histories.
In 1990, a similar field sampling and analysis was conducted on a sample
grid that covered the entire landfill surf ace. No PCBs were detected in any of
the landfill cap soil and vegetation samples. Results of the new sampling
and analysis can be compared to these older data to show historical trends.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
Areas to be targeted for PCB surface soil and vegetation sampling include: 1)
Landfill cap in an area of approximately 1 O' radius from the central air vent,
2) Landfill cap in an area in approximately 1 O' radius from the pump house
and Leachate collection system outlet pipe, and 3) any specially targeted area
that may show liquid seepage or slumping of soils on or adjacent to the
landfill cap.
SAMPLING PERSONNEL REQUIREMENTS
A total of four personnel will be required to accomplish this task in a timely
manner within the main sampling day. Surface soil sampling around the
access structures to the landfill contents, i.e., the air vent and the leachate
collection system will require scheduling coordination with those sampling
activities.

FIELD EQUIPMENT REQUIRED
Standard soil sampling equipment will be used including scoops, bowls. or
buckets that can be decontaminated or are disposable. Field portable
decontamination equipment will be required.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHOD{$}
Soil samples collected in this sampling effort will be analyzed by EPA Method
8081 for PCB content.
QUALITY ASSURANCE PLANONCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
Soil samples from this effort will be available for true split sampling up to the
20% number established by the Working Group.
CARBON & SAND FILTER SAMPLES
PURPOSE
• Sample and analyze material from the carbon and sand filters that are a
part of the leachate collection system. Samples will be analyzed for PCB
congeners.
FIELD SAMPLING METHOD
After removing the concrete covering over the carbon and sand filters, the
surface accumulations (primarily gravel) will be brushed back. The industrial
fabric coverin_g the sand and carbon filters will be folded back and samples of
each filter substrate will be taken. All equipment used must be properly
decontaminated before and after use.
FIELD SAMPLING LOCATION($) (ATTACH SKETCH IF APPROPRIATE)
A sketch of the sand a11d fabric filters is included with this description. The
sand and fabric filters are part of the leachate treatment system which only
briefly operated in the first year following landfill closure. The filters are
housed in a concrete structure just below the pump house, visible on the
north end of the landfill.
SAMPLING PERSONNEL REQUIREMENTS
Two sampling personnel will be required to perform this activity. However,
the time required should be less than one hour, thus, these individuals can be
detailed from other activities.
FIELD EQUIPMENT REQUIRED
Routine organic chemical sampling equipment will be used in acquiring these
samples.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHODCSl
PCB analysis will be performed using EPA Method 8081.
QUALITY ASSURANCE PLAN(INCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
As requested by the science advisor, up to 20% of samples taken from the
leachate collection and treatment system (that includes the sand and carbon
filters) will be split or duplicated for independent analytical analysis.

SEDIMENTATION BASIN SUBSTRATE SAMPLES
PURPOSE
• Sample and analyze material from the substrate (soils) at the bottom of
the sedimentation basis that is a part of the leachate treatment system.
Samples will be analyzed for PCB congeners.
FIELD SAMPLING METHOD
Standard soil field sampling method will be employed. Up to 5 randomly
placed substrate samples will be taken by appropriate field collection devices,
then transferred to a properly prepared and labeled container for laboratory
analysis for PCBs. The soil sample need only be analyzed to a depth of 3 to
5" due to the nature of PCBs in binding to the surface substrate. Low levels
of PCBs (near the detection limit) were found in these substrate materials in
earlier sampling activities in this same basin.
FIELD SAMPLING LOCATION(S) (ATTACH SKETCH IF APPROPRIATE)
The sedimentation basin is located outside the main landfill fence to the
north of the landfill. It can be identified as a depression in the ground, that is
completely vegetated by grass and some taller weeds. The sedimentation
basin has never routinely held any liquid and was used only briefly during the
first year following closure of the landfill.
SAMPLING PERSONNEL REQUIREMENTS
Two sampling personnel will be required to perform this activity. However,
the time required should be one to two hours, thus, these individuals may be
detailed from other activities.
FIELD EQUIPMENT REQUIRED
Routine organic chemical sampling equipment will be used in acquiring these
samples.
PERSONAL PROTECTIVE EQUIPMENT
Level D protective equipment for sampling personnel will be required. This
includes long-sleeved shirts, long-legged pants, safety shoes, impact
protective eyeware, and disposable surgical gloves.
CHEMICAL TEST METHODCS>
PCB analysis will be performed using EPA Method 8081.
QUALITY ASSURANCE PLANONCLUDE SPLIT SAMPLES AND ALTERNATE LABS)
As requested by the science advisor, up to 20% of samples taken from the
leachate collection and treatment system (that includes the sedimentation
basin) will be split or duplicated for independent analytical analysis.

History of the Site:
Between June, 1978 and August, 1978, over 30,000 gallons of industrial liquid waste material identified as
PCBs (Arochlor 1260 and Arochlor 1262) were discharged deliberately along the shoulders of approzximatley
150 miles of NC highways. In June, 1979, EPA approved a tract of land (previously used for agriculture) in
Warren County as the disposal site for the PCB-contaminated roadside soil. The landfill (constructed in 1983-
1984 and permitted under the Toxic Substances Control Act -TSCA) contains about 40,000 cubic yards of soil
contaminated with PCBs. The concentration of PCBs in the landfill ranges from 46 to 200 ppm, averaging
about 135 ppm.
