EXECUTIVE SUMMARY
Off-Site Groundwater Quality Investigation
North Carolina State University
December 31, 1997
North Carolina State University (NCSU) engaged GEi Consultants, Inc. (GEi) to evaluate the
potential for natural attenuation processes to remediate groundwater affected by release of
chlorinated volatile organic compounds (VOCs) from the Lot 86 Superfund Site in Raleigh, North
Carolina.
The U.S. Environmental Protection Agency (EPA) has issued a Record of Decision (ROD) that
calls for NCSU to pump contaminated groundwater until prescribed groundwater remedial
objectives are achieved. The ROD allows deferring implementation of groundwater pumping for
two years, during which time NCSU may submit information to EPA providing evidence that
groundwater contamination is being reduced by naturally-occurring processes. If the evidence is
persuasive, EPA will consider changing the selected groundwater remedy.
The scope of the groundwater natural attenuation project includes the following tasks: lA)
preparing work plans for groundwater sampling and analysis; lB) collecting and analyzing
groundwater samples from 24 existing monitoring wells; and 2) applying the results of the
analyses to a Bioattenuation Screening Process contained in a draft document developed by the
U.S. Air Force, Technical Protocol for Evaluating Natural Attenuaiion of Chlorinated Solvents
in Groundwater (the Technical Protocol). The Bioattenuation Screening Process is an initial step
that allows investigators to determine, with minimal investment in data collection, whether natural
bioattenuation is likely to be a viable remedial alternative. The process uses a scoring system in
which parameters are awarded points based on their potential for enhancing conditions for natural
attenuation and on indications that natural attenuation is occurring. If the screening score for the
site indicates that natural attenuation appears to viable, NCSU may proceed with the following
additional tasks: 3) simulating contaminant transport and bioattenuation using a two-dimensional
computer model, BIOPLUMEII; and 4) preparing documentation presenting a weight-of-evidence
demonstration that natural attenuation is capable of achieving remedial objectives for the site.
GEi has completed tasks lA through 2 above. Application of the Bioattenuation Screening
Process indicated there is adequate evidence of biodegradation of chlorinated organics at the site
to warrant more detailed evaluation of natural attenuation, including bioattenuation. NCSU
directed GEi to further investigate off-site groundwater quality before proceeding with
contaminant transport and bioattenuation modeling. Primary objectives for this investigation were
to: l) evaluate the extent of horizontal migration of VOCs in shallow groundwater downgradient
of the site in a highway right-of-way immediately north of the site, and 2) evaluate the presence
of compounds resulting from biodegradation of chlorinated VOCs (i.e., daughter products) in
downgradient shallow groundwater.
The off-site groundwater quality investigation consisted of collecting samples of shallow
groundwater from 11 locations, all downgradient of existing groundwater monitoring wells, using

the direct-push sampling method. By this method, a small-diameter sampler is driven into the
subsurface with a impact hammer to a desired depth, a groundwater sample is collected from the
sampler, the sampler is removed, and the resulting hole is backfilled. Analysis of the
groundwater samples for voes indicated that voes in shallow groundwater have migrated north
into the highway right-of-way. voes consistent with those detected near the source, but at lower
concentrations, were detected approximately 100 feet north of monitoring wells with the highest
voe concentrations. A relative few voes were detected on the north side of the right-of-way,
approximately 300 to 400 feet from the source, at very low concentrations, Based on findings
from this investigation and previous investigations, the direction of voe migration from the
source appears to range from northwesterly to northeasterly. The northeasterly component of
migration may be more substantial than was concluded from previous investigations.
Also based on findings from this investigation and previous investigations, GEi concludes that at
least two, and possibly five, daughter products have been detected in groundwater samples
collect_ed downgradient of the source. However, compounds that are distinctly derived from
degradation of chlorinated voes have not been detected in any groundwater samples. Decreasing
concentrations of one possible intermediate daughter product (methylene chloride), relative to
concentrations of its possible parent compounds (carbon tetrachloride and chloroform), indicate
at least some degree of biodegradation of chlorinated voes downgradient of the source.

1 _Q INTRODUCTION
1 .1 Purpose and Scope
Off-Site Groundwater Quality Investigation
North Carolina State University
December 31, 1997
North Carolina State University (NCSU) is evaluating the potential for natural attenuation
processes to remediate groundwater affected by release of chlorinated volatile organic compounds
(VOCs) from the Lot 86 Superfund Site in Raleigh, North Carolina. The predominant compounds
found in groundwater at the site are chloroform, methylene chloride, benzene, carbon
tetrachloride, and trichloroethene.
The U.S. Environmental Protection Agency (EPA) has issued a Record of Decision (ROD) that
calls for NCSU to pump contaminated groundwater until prescribed groundwater remedial
objectives are achieved. The ROD allows deferring implementation of groundwater pumping for
two years, during which time NCSU may submit information to EPA providing evidence that
groundwater contamination is being reduced by naturally-occurring processes. If the evidence is
persuasive, EPA will consider changing the selected groundwater remedy.
NCSU, under contract with GEI Consultants, Inc. (GEI), is evaluating whether subsurface
conditions at the site are conducive to natural attenuation and whether there is evidence that
natural attenuation is in process. The basis for the evaluation procedure is a Bioattenuation
Screening Process contained in a draft document developed by the U.S. Air Force, Technical
Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Groundwater (the
Technical Protocol). The natural attenuation demonstration project for the Lot 86 Superfund Site
is organized as follows:
Task lA Sampling and Analysis, Health and Safety, and Quality Assurance
Project Plan
Task I B Sampling and Analysis Implementation
Task 2 Screening Analysis
Task 3 Modeling
Task 4 Complete Natural Attenuation Demonstration
Task IA was completed with submissi_on of the Sampling and Analysis Plan (GEI, 1997a), the
Quality Assurance Project Plan (GEI, 1997b), and the Health and Safety Plan (appended to the
Sampling and Analysis Plan), all dated May 9, 1997. Task IB was completed with submission

of a report dated August 5, 1997 (GEi, 1997c), consisting 0f data tables providing results of field
measurements and laboratory analyses conducted on gr0tJndwater samples from the site, as
recommended by the Technical Protocol for evaluating natural· .attenuation of chlorinated
compounds in groundwater.
Task 2 was completed with submission of a report dated August 29, 1997 (GEi, 1997d),
consisting of an evaluation of whether biodegradation of chlorinated compounds appears to be
occurring, per a Bioattenuation Screening Process included in the Technical Protocol. This
evaluation was conducted to help NCSU decide whether natural attenuation has at least the
potential to reduce concentrations of chlorinated compounds in groundwater to below remedial
objectives before transported contaminants reach receptors. Before making this decision, NCSU
chose to first conduct a preliminary investigation of off-site groundwater quality to evaluate the
horizontal extent of the VOC plume in shallow groundwater downgradient of the site. NCSU
authorized GEi to conduct the following work:
•
•
•
•
Mobilize a subcontractor capable of collecting shallow groundwater samples using the
direct-push technique (i.e., without installing groundwater monitoring wells).
Collect groundwater samples at an estimated 10 to 20 locations. in the right-of-way of
Wade Avenue Extension, adjacent to the site.
Analyze the groundwater samples for aromatic and chlorinated hydrocarbons using Method
8260.
Survey the locations and elevations of the groundwater sampling points and add them to
the base map for the site.
• Prepare a report of the field work, field observations and measurements, results of
analyses, and interpretation of resulting data.

2.0 SITE BACKGROUND
Off-Site Groundwater Quality Investigation
North Carolina State University
December 31, 1997
The North Carolina State University (NCSU) Lot 86 Superfund Site received solvents, pesticides,
heavy metals, acids, and some low-level radioactive laboratory wastes from 1969 to 1980. The
wastes were placed in 22 ten-foot-deep trenches of various lengths, totaling 2,000 feet.
Groundwater in the area of the site contains volatile organic compounds (VOCs), principally
chloroform, methylene chloride, benzene, carbon tetrachloride, and trichloroethene. Lower
concentrations of semi-volatile organic compounds and pesticides also have been detected in
groundwater. Contaminant concentrations are higher in the shallow aquifer than in the bedrock
aquifer and decrease with distance from the site.
NCSU. began monitoring the site in 1981. The site was proposed for listing on the National
Priorities List (NPL) in October 1984 and was listed on the NPL in June 1986. The U.S.
Environmental Protection Agency (EPA) began investigating the site in 1987, and NCSU began
a remedial investigation/feasibility study (RI/FS) of the site in 1992.
The RI focused on confirming the findings of earlier groundwater investigations, using
methodologies that conformed to EPA Region IV protocols (Brown and Caldwell, 1994). The FS
examined a range of relatively conventional site remediation approaches, including, for
groundwater, institutional action, groundwater treatment, and. biotreatment, and, for subsurface
soils, institutional action, containment and capping, soil vapor extraction, incineration, and low-
temperature thermal desorption. The evaluation of alternatives in the FS did not demonstrate that
one alternative was preferable to the others (Brown and Caldwell, 1995).
Following completion of the RI/FS, NCSU in 1995 undertook an additional investigation to
evaluate the content of the waste in the trenches, obtain updated groundwater quality data, and
model the transport and biodegradation of four primary groundwater contaminants. The
investigation determined the following: 1) free and containerized liquid-phase chemical wastes
remain in the trenches; 2) the wastes in the trenches continue to serve as a significant source of
contaminants that can be released to groundwater; 3) after the source materials have been removed
or stabilized, it is possible that the groundwater contaminant plume could be adequately controlled
by natural biodegradation processes; and 4) the extent of the plume would be significantly larger
than.observed if not for the attenuating effects of contaminant biodegradation (S&ME, 1996).
Based on the these findings, NCSU in 1996 evaluated natural attenuation as a remedial approach
(NCSU, 1996a) and prepared a revised FS that examined, among other alternatives, in-place
stabilization of the trench materials and natural attenuation of groundwater contaminants (NCSU,

1996b). The earlier FS did not examine either of these alternatives, and the revised FS ranked
these alternatives highes_t among all the alternatives.
EPA issued its Record of Decision (ROD) for the site in September 1996 (EPA, 1996). The ROD
calls for groundwater to be pumped and treated. This action was estimated to require 30 years.
The ROD allows delay of the groundwater remedy for two years (until September 1998), during
which time EPA will consider new evidence that NCSU may submit demonstrating that "reduction
of groundwater contamination is occurring at the site by means of natural processes. If analytical
results such as but not limited to a decrease of groundwater contamination or the existence of
breakdown products of the original contaminants is presented, EPA will consider a change in
remedy." The North Carolina Division of Waste Management concurred with this approach,
provided that natural attenuation is evaluated using appropriate guidance, such as that developed
by the U.S. Air Force Center for Environmental Excellence, Technical Pro/Ocolfor Evaluating
Natural Attenuation of Chlorinated Solvents in Ground Water (Draft -Revision 1) (the Technical
Protocol) (Wiedemeier et al., 1996).
NCSU contracted with GEI to evaluate natural attenuation for the site using the Technical
Protocol. GEI prepared project plans (GEI, 1997a and b) under Task IA and; in June 1997 under
Task 1B, collected groundwater samples from 24 monitoring wells and analyzed them for the
following parameters specified in the Technical Protocol's Bioattenuation Screening Process:

The results of these analyses are summarized in GEI, 1997c. Consistent with results from
previous investigations of the site, the predominant volatile organic compounds in groundwater
were as follows:
• Chlorinated aromatic hydrocarbons (CAHs): chloroform, methylene chloride, carbon
ietrach_loride, tetrachloroethene, trichloroethene, 1,2-dichloropropane, and chlorobenzene.
• Non-CAHs: toluene, benzene, xylenes, and 1,2-dibromomethane .
Concentrations of individual compounds in parts per million (milligrams per liter, or mg/L) were
prevalent in samples from monitoring wells immediately downgradient (northwest) of the source
burial trenches (e.g., monitoring well MW02; refer to Figure 2) and approximately 125 feet
downgradient of the source at the downgradient limit of the site's monitoring well network (e.g.,
MW12). VOCs either were not detected or were detected at concentrations below remedial
objectives of the ROD in the upgradient background wells (MW32, MW33, MW34S, and
MW34D) and in wells MWl0 and MW13 within the contaminant plume.
Three bedrock wells within the contaminant plume were sampled. Bedrock groundwater at wells
MW38 and MW35D was not affected by VOC contaminant migration (the sample from well
MW38 contained 1 ug/L of chloroform). However, six CAHs were detected in the sample from
well MW36D at concentrations above remedial objectives.
As had been shown in previous investigations, shallow groundwater was interpreted to flow across
and downgradient from the site in a northwesterly direction. A northeasterly flow component
downgradient from the site was thought to be plausible, but could not be evaluated with the
available data.
The following compares concentrations in three downgradient-most monitoring wells that were
sampled both in during the remedial investigation in late 1993 and early 1994 and by GEI in June
1997:

A former shallow monitoring well, MW20 (see Figure 2), was located in the median of Wade
Avenue Extension until it was closed to accommodate realignment of the highway. The well was
sampled in 1993/1994 during the RI. Chloroform was detected at a concentration of 25 µg/l and
was the only voe detected.
As the above data show, in 1993/1994 only a relative few VOCs had migrated from the waste
burial area to the highway right-of-way, and only chloroform had been detected in the well in the
highway median. From 1993/1994 to June 1997, VOC concentrations decreased at well MW15
and increased only nominally at well MW17; these wells are the western-most of the downgradient
wells sampled on both occasions. In well MW16, the eastern-most downgradient well sampled

on both occasions, voe concentrations increased dramatically, some by three to four orders of
magnitude.
Based on the results of the groundwater sampling and analysis conducted in June 1997, GEI
employed a biodegradation scoring system of the Technical Protocol to evaluate whether
biodegradation of eAHs appears to be occurring at the site and to help NeSU decide whether
natural attenuation has at least the potential to reduce concentrations of eAHs in groundwater to
below remedial objectives before the compounds are transported to receptors. This evaluation is
documented in a report dated August 29, 1997 (GEI, 1997d). Application of the scoring system
indicated that there is adequate evidence of biodegradation of eAHs at the site to warrant more
detailed evaluation of natural attenuation. In apparent conflict with subsurface conditions favoring
natural attenuation, few compounds considered to be products of reductive dechlorination of
CAHs (i.e., "daughter" products of the "parent" compounds) were detected in groundwater
samples collected from the site. It was also apparent that the downgradient extent of voe
migration from the waste burial area could not be determined using only the existing monitoring-
well network.
To evaluate the possible presence of daughter products in groundwater farther downgradient than
the existing monitoring wells, and to evaluate how far and in what directions voes have migrated
into the Wade Avenue Extension right-of-way, NeSU authorized GEI to conduct a preliminary
study of off-site groundwater quality using the direct-push technique of groundwater sampling.
This technique was selected because: I) the technique leaves no permanent monitoring fixture that
would need to be avoided or removed to enable ongoing construction for realignment of the
highway, and 2) groundwater samples can be collected at a large number of locations in a short
time, enabling cost-effective coverage of a large area.

3_0 INVESTIGATION METHODOLOGY
3.1 Investigation Strategy
This investigation was conducted to: I) evaluate the extent of migration of voes in shallow
groundwater downgradient of the existing monitoring wells on the south side of the right-of-way
of Wade Avenue Extension, and 2) evaluate the presence of daughter products, or products of
reductive dechlorination, of eAHs known or believed to have been placed in the waste burial area
of the site.
A significant constraint for conducting the investigation was ongoing construction for realignment
of Wade Avenue Extension in the area immediately north of the site, which would have made
installation of permanent monitoring wells logistically difficult. To allow collection of shallow.
groundwater samples from temporary collection points, the "direct-push" method of sample
collection (described in Section 3.2) was used. This method also allowed collection of
groundwater samples from more locations than would comparable effort for installing and
sampling monitoring wells.
The area for off-site groundwater sampling was selected to be downgradient from the waste burial
area and from the downgradient-most monitoring wells where the highest voe concentrations
were detected (wells MW12 and MW16; see Figure 2). Previous investigations identified a
northwesterly direction of groundwater flow, with a possible northeasterly component of flow.
A northeasterly component of voe migration also is probable, as chloroform was detected in
monitoring well MW20 (now closed) during the remedial investigation.
Two lines of five direct-push sampling locations each were established in the right-of-way of
Wade Avenue Extension (see Figure 2): one along the north side of the west-bound lanes,
consisting of direct-push sampling locations DPOI through DPOS, and the other in the highway
median, consisting of locations DP06, DP07, DP09, DPIO, and DPII. An eleventh sampling
location, DP08, was established south of the line in the median, closer to monitoring wells MW12
and MW16. Depths for collecting groundwater samples were selected to be at elevations
comparable to the elevations of the screened intervals of the line of downgradient-most monitoring
wells on the south side of the right-of-way (wells MW13, MW17, MW12, MW16, and MWI I).

3.2 Groundwater Sample Collection
Off-Site Groundwater Quality Investigation
North Carolina State University
December 31, 1997
The direct-push groundwater sampling was accomplished on November 17, 1997, using a
Geoprobe Screen Point Groundwater Sampler. The equipment and operators were provided by
Probe Technology, Inc., of Concord, North Carolina. The work was conducted under the
direction of a GEi engineer.
The direct-push sampler was a I-inch-diameter, wire-wound stainless steel screen that is sealed
within a stainless steel sheath while it is driven to the desired depth using a hydraulically driven
impact hammer mounted on a four-wheel-drive vehicle. The desired sampling depth was reached
by adding multiple stainless steel extension rods as the sampler was driven. When the desired
depth was reached, the probe rods were retracted 41 inches, using the impact hammer to expose
the 41-inch-long screen. The sampler screen was held in position in the formation by a
expendable drive point that does not retract with the extension rods.
After allowing sufficient time for groundwater to enter the sampler, groundwater samples were
collected using new ½-inch-diameter high-density polyethylene tubing with a clean check valve
inserted at the bottom end of the tube. By moving the tubing repeatedly up and down within the
water column in the extension rods and sampler screen, a groundwater sample was made to rise
in the tube (i.e., an inertial pumping action). If sufficient volume of water entered the tubing,
inertial pumping was continued to bring a groundwater sample to the top end of the tubing, from
which the sample was collected in 40 ml VOA vials provided by the laboratory. If the volume
of water in the sampler was not sufficient to bring a sample to the surface using inertial pumping,
the tubing was removed from the extension rods and used as a small-diameter bailer, whereby the
water was transferred from the tubing to the sample vials either by inverting the tubing and slowly
pouring the sample out the top end of the tube or by removing the check valve and slpwly pouring
the sample out the bottom end of the tube.
Immediately after collecting the groundwater sample in VOA vials for laboratory analysis, two
additional samples were collected for field measurements. A sample was placed in a glass beaker
for measurement of temperature, specific conductivity, and pH, another sample was placed in a
glass jar for headspace monitoring. The headspace sample was placed in a I-liter jar with a lid
in a warm location for five to IO minutes. The sample was then shaken, the jar lid was opened
slightly to allow insertion of the probe of a photoionization detector (PIO), and the PIO reading
of the headspace vapor in the jar was recorded.

After the groundwater sample was collected, the extension rods and sampler screen were removed
from the ground using reverse action of the impact hammer. The hole left by removing the
sampler was filled by pouring granular bentonite directly into the hole. All extension rods and
sampler screens were thoroughly decontaminated before and after each use with high-pressure hot
water. The source of the decontamination water· was the City of Raleigh water distribution
system. Decontamination water was contained and placed in a 55-gallon drum that was
transferred to the inside of the fenced area of the site at the completion of the work.
Two quality-control samples, a duplicate groundwater sample and trip blank, were collected. The
duplicate sample was collected from location DPIO. A trip blank provided by the laboratory
accompanied the groundwater samples during the field work and their transport to the laboratory.
The samples were chilled using water ice in a cooler and were hand-delivered to the laboratory
by the laboratory's courier. Chain-of-custody documentation was maintained.
Horizontal coordinates and elevations of the ground surface at the 11 direct-push sampling
locations were surveyed on November 18, 1997, by Murphy Hobson Sacks, who provided GEi
with the survey data and a CAD file map of the sampling locations and edges of the highway
pavement.
3.3 Groundwater Sample Laboratory Analysis
Twelve groundwater samples (including one duplicate sample) and one trip b_lank were received
by the laboratory, Pace Analytical Services, Inc. (Pace}, in Huntersville, North Carolina, on
November 18, 1997. Analyses were conducted for VOCs using EPA SW-846 Method 8260.

4.0 FIELD OBSERVATIONS AND MEASUREMENTS
Depths and elevations of the screened intervals, based on surveyed elevations of the ground
surface, for each direct-push sampling point are provided in Table 1. The total depth that the_
sampler was driven is the depth of the bottom of the screened interval. Refusal on hard,
impenetrable material controlled the total depth at locations DP0S, DP08, and DP! 1. At locations
DP0l, DP06, and DP09, the subsurface material was very hard, but penetrable at a slow rate, at
the depths where driving the sampler was terminated. At the remaining locations, the material
at termination depths was hard, but penetrable at a moderate rate.
Table 1 also provides depth and elevation data for the five monitoring wells along the south side
of the Wade Avenue Extension right-of-way (MW13, MW17, MW12, MW16, and MWll) and
three selected monitoring wells between the right-of-way and the source waste burial trenches
(MW06, MW07, and MW08) and the depths and elevations of groundwater levels in those wells
in June 1997. The profile on Figure 3 shows the vertical relationships of the screened intervals
of these wells and of the 11 direct-push sampling points.
Measurements of the field parameters (headspace PIO reading, temperature, specific conductivity,
and pH) for each of the 11 direct-push sampling locations are provided in Table 2 .

6.0 EVALUATION OF THE RESULTS
6.1 Horizontal Extent of VOC Migration
VOCs in shallow groundwater have migrated into the interior of the Wade Avenue Extension
right-of-way. VOC concentrations in the right-of-way interior are substantially lower than those
detected in the monitoring wells at the south side of the highway right-of-way, which are screened
at elevations comparable to the screened intervals of the direct-push sampling points. Detection
of VOCs at the eastern-most direct-push locations confirms an easterly component of VOC
migration from the waste burial area.
Chloroform was detected at the highest concentration (910 µg/l) at location DP08, which is the
direct-push sampling location closest to the waste j)urial area and to monitoring wells MW12 and
MW16, wells in \he right-of-way where high VOC concentrations were detected in June 1997.
Detection of chloroform in the direct-push samples is consistent with its prevalence,in monitoring
wells near the waste burial area (GEI, 1997c) and in wells MW12, MW16, and MWll along the
south side of the right-of-way, and with its detection in well MW20, which was in the highway
median before it was closed.
With the exception of compounds detected at location DP08, VOC concentrations were less than
the laboratory's reporting limit (5 or 10 µg/l, depending on the compound). Except for
naphthalene and 1,2,3-trichlorobenzene, all of the compounds detected in the direct-push
groundwater samples also were detected in June 1997 in samples from the five monitoring wells
q!,} the south side of the right-of-way. NaphthaJene also was detected in the laboratory's method
blank, indicating its detection in the direct-push groundwater samples could be a laboratory
artifact, although it also was detected in samples from wells MW02 (22 µg/l) and MW03 (40
µg/l), both near the waste burial area, in June 1997. 1,2,3-Trichlorobenzene was not detected at
any of the wells sampled in June 1997. Toluene was detected in all but two (DP09 and DPl0) of
the direct-push groundwater samples and was detected in all five of the monitoring wells on the
south side of the right-of-way in June 1997.
Methylene chloride was detected in the trip blank at a concentration of 6 µg/l, which GEI
attributes to the presence and use of methylene chloride in the laboratory. Methylene chloride was
not detected in any of the direct-push groundwater samples.

6.2 Evidence of Bioattenuation
The presence of daughter products in groundwater downgradient of the source area is an important
indication that CAHs are being dechlorinated. It therefore is important to attempt to distinguish
between parent compounds and daughter products among the CAHs detected downgradient of the
source. Partial sequences of dechlorination in which the detected CAHs can be involved are as
follow:
1)
2)
3)
"*"
Chloromethanes: Carbon tetrachloride➔Chloroform➔Methylene chloride
Chlorinated ethanes: 1,1,2,2-TCA➔l,1,2-TCA➔l,2 -DCA
1, 1,2,2-TCA➔l, I, 1-TCA➔l, 1-DCE
1,1,l-TCA➔l,I-DCA ➔1,1-DCE➔* 1,1-DCE
Chlorinated ethcncs: PCE➔ TCE
TCE➔ I, 1-DCE
TCE➔ 1,2-DCE➔Vinyl chloride
1,2-DCE➔ 1,2-DCA
indicates this dechlorination step is abiotic.
Based on these sequences and limited information about the materials place in the source waste
burial trenches, the following evaluates parent compounds and daughter products detected
downgradient of the source:
• Parent compounds. Because they are the most highly chlorinated compounds and have been
produced commercially, several of the detected CAHs [e.g., carbon tetrachloride, 1,1,2,2-
trichloroethane (1,1,2,2-TCA), and tetrachloroethene (PCE)] are, by definition, parent
compounds.
• Parent compounds and/or daughter products. Because some of the detected CAHs either
could have been produced commercially or could be products of reductive dechlorination, and
because records of waste disposal in the trenches are not sufficiently detailed to identify
specific compounds placed in the trenches, some of the other detected CAHs [e.g.,
chlorofonn, methylene chloride, trichloroethenc (TCE), 1, 1, !-trichloroethane (1, 1, 1-TCA)]
could be either parent compounds or daughter products, or both.

• Daughter products. Some of the detected CAHs [e,g., 1,1,2-trichloroethane (1,1,2-TCA),
1,2-dichloroethane (1,2-DCA)I both have not been produced commercially and can be
products of reductive dechlorination. Therefore, these compounds are likely to be daughter
products, although they could have been present in trace concentrations in some common
commercial solvents. Compounds that are distinctly derived from degradation of CAHs, such
as cis-1,2-dichloroethenc, vinyl chloride, and chloroethane, were not detected in samples from
the monitoring wells or in the direct-push samples.
Decreasing concentrations of methylene chloride relative to other CAHs downgradient from the
source also can indicate that selective reductive dechlorination of methylene chloride is occurring.
Methylene chloride can be selectively biodegraded by natural microorganisms, leaving behind the.
more recalcitrant carbon tetrachloride and chloroform. GEI has observed preferential
biodegradation of methylene chloride at other groundwater-contamination sites. Unlike other
CAHs, methylene chloride can serve as a primary substrate, aerobically or anaerobically, to
provide carbon and energy needed for the growth of microorganisms.
Three chloromethane compounds (carbon tetrachloride, chloroform, and methylene chloride) were
detected at the three easternmost monitoring wells on the south side of the right-of-way (MW12,
MW16, and MWll) and at three selected monitoring wells between the source and the right-of-
way (MW06, MW07, and MW08). Carbon tetrachloride and chloroform also were detected in
the sample from location DP08, but methylene chloride was not detected. The following table
compares mole fractions of each of these compounds at these monitoring wells and at direct-push
location DP08,
Carbon tetrachloride 0.028 0.016 0.011 0.004
0.018 average
Chloroform 0.89 0.79 0.82 0,83 0.99
0.83 average
Methylene chloride 0.083 0.20 0.17 0.12
0.151 average
The mole fraction is the molar concentration of the compound divided by the sum of the molar concentrations of the
three chloromethanc compounds .
Methylene chloride was not detected at direct-push location DP08.

The above data show that the mole fraction of methylene chloride decreases in a downgradient
(northerly) direction, while mole fractions of carbon tetrachloride and chloroform increase. The
mole fraction of methylene chloride decreases from 0.151 (average of wells MW06, MW07, and
MW08) to 0.058 (average of downgradient wells MW12, MW16, and MWll) to not detected
further downgradient at location DP08. Concurrently, as the data indicate, the mole fractions of
carbon tetrachloride and chloroform increase in the downgradient direction. This pattern of
concentration variation suggests attenuation of all three choromethanes by' dilution and further,
selective attenuation of methylene chloride by reductive dechlorination. Sorption and
volatilization cannot account for the observed variations in chloromethane concentrations.
Methylene chloride has less tendency to sorb to soil particles than the other compounds, as
indicated by its lower soil-adsorption coefficient. Similarly, methylene chloride has less tendency
to volatilize than the other compounds, as indicated by its lower Henry's constant. Based on these
characteristics, methylene chloride would be expected to advance at a more-rapid rate than those
of the other compounds, rather than at a retarded rate as indicated by the trends in the above mole
fractions.

7 .0 CONCLUSIONS
Off-Site Groundwater Quality Investigation
North Carolina State University
December 31, 1997 1 7
GEi used data from several sources to evaluate the horizontal extent of voe migration and the
·presence of daughter products in shallow groundwater downgradient of the source waste burial
trenches at the site. The data were collected using different methods (monitoring wells and direct-
push sampling), at different times (1993/1994, June 1997, and November 1997), and in different
seasons (summer, fall, and winter). While these differences are not ideal for evaluating site
conditions, trends in site conditions can be reasonably and cost-effectively evaluated with the data
available.
Based on the findings of previous investigations and of this off-site groundwater quality
investigation, GEi draws the following conclusions pertaining to the horizontal extent of voe
migration at the site:
• voes in shallow groundwater have migrated northerly into the interior of the Wade Avenue
Extension right-of-way.
• voes consistent with those detected near the source waste burial trenches and in existing
monitoring wells, but at lower concentrations, were detected approximately 100 feet north of
the two downgradient-m◊-st monitoring wells (MW12 and MW16) with the highest voes
concentrations.
• A relative few voes were detected on the north side of the right-of-way, approximately 300
to 400 feet from the source, at very low concentrations below the laboratory's reporting limit.
• The direction of voe migration from the source appears to range from northwesterly to
northeasterly; the northeasterly component of migration may be more substantial than was
concluded from previous investigations.
GEi draws the following conclusions pertaining to evidence of bioattenuation of eAHs in shallow
groundwater at the site:
• Two probable daughter products (I, 1,2-TeA and 1,2-DeA) and. three possible daughter
products (chloroform, methylene chloride, and TeE) of reductive dechlorination have been
detected in groundwater samples collected downgradient of the source waste burial trenches.

• Compounds that are distinctly derived from degradation of CAHs, such as cis-1,2-
dichloroethene, vinyl chloride, and chloroethane, have not been detected in samples collected
from either downgradient monitoring wells or in samples collected by the direct-push method.
• A decreasing concentration of methylene chloride in a downgradient direction, relative to other
chloromethanes (carbon tetrachloride and chloroform), indicates that methylene chloride is
being biodegraded as the VOCs migrate downgradient from the source into the Wade Avenue
Extension right-of-way.
