Mark, Sherri and Melanie
I just wanted to send you a quick e-mail to let you know that we completed
the full scale permanganate injection in the Phase 1 area (near the former
Sears distribution center building) last week on the July 11th. Starting on
June 18, 2001 we safely injected a total of 21,450 lbs of permanganate in 66
geoprobe injection points. We have follow-up monitoring events scheduled
for August and September to determine the effectiveness of the injection.
After we compile the data from the injection and obtain the monitoring
results, we will submit a these data to you for review. We will also be
requesting NCDENR approval of the UIC permit for the Phase 3 full scale
injection in the source area. Timely receipt of this approval is critical
for the success of this project.
In the next several months, we will also be planning the full scale
permanganate injection in the Phase 2 area. This next phase of full scale
injection is tentatively scheduled to start in late September and to last
for several months. The detailed design of this injection event will be
based on lessos learned and data collected during Phase 1, as well as the
most current groundwater analytical data from the area. As you know, we
have been operating a High Vacuum Dual Phase/SVE remediation system in this
area since March of this year.
While on site in June and July, we also collected some geoprobe soil samples
from the Phase 3 source area and are analyzing these samples now to provide
data for design of the permanganate injection in this area.
Finally, we have not heard anything from NCDENR regarding the CAP approval.
My understanding after our June 7, 2001 meeting was that someone from NCDENR
would be looking at this. Can I get a status update?
Let me know if you have any questions or need more information.
Thanks,

EXECUTIVE SUMMARY
The CSA investigation performed in 1999 by IT Corporation, previous to this report being
prepared, was an extension of previous investigations conducted by Mortensen Engineering, Inc.
and IT Corporation. These investigations are referenced in Section 1.1 and salient information
from previous investigations that was used in the analysis of present site conditions is tabulated
or appended to this report. The investigation was designed to collect data necessary to delineate
adsorbed and dissolved phase volatile organic compounds (mainly tetrachloroethylene) present
within the subsurface of the W. P. Ballard and impacted downgradient properties.
Constituents of Concern (CoCs) on the W. P. Ballard and downgradient properties include
Petroleum Hydrocarbons from a gasoline UST Release and Perchloroethene (PCE), also known
as Tetrachloroethylene, from PCE AST and possibly transfer release(s).
Subsurface data collected during drilling operations indicates that the site stratigraphy consists of
Amphibolite Gneiss overlain by saprolite that consists of unconsolidated mixtures of
predominantly silt -sized particles with varying amounts of sand and clay -sized particles. The
Amphibolite Gneiss bedrock is very competent (few fractures), light gray to dark green and was
encountered at depths ranging from 105 to 123 feet below grade The saprolite can be separated
into two zones based on density and/or degree of weathering. The upper saprolite zone is soft to
moderately consolidated and is delineated at depth by auger refusal occurring at depths ranging
between 45 and 79 feet with the average depth being approximately 69 feet. The lower zone
appears to be comprised of differentially weathered bedrock and has been defined based on
depths at which auger refusal and slower rotary hammer drilling rates were encountered. Other
than the interface between the unconsolidated overburden and the competent bedrock, significant
lithologic changes have not been observed in materials beneath the site.
Subsurface exploration indicates that the saprolite is saturated below a depth ranging from 7 to
28 feet below ground surface and in a very limited number of fractures in the bedrock allow
groundwater to penetrate to an undetermined depth in at least one location. Due to the limited
fracturing observed in cores and the lack of apparent weathering in observed fractures it is
concluded that the bedrock is not a conduit for groundwater. The aquifer beneath the site is
unconfined and the water surface elevations generally correspond with changes in the natural
topography. The predominant groundwater flow direction at the site is to the east with an
average hydraulic gradient of 0.023 feet -per -foot and the average hydraulic conductivity is 1.55
ft/day. Hydraulic conductivity varies significantly between the shallow and deep saprolite zones
due to the degree of weathering of the in -place materials.
Hydrocarbon constituents in soil appear to be limited in extent and are less than the Commercial -
Industrial standards published by NCDENR in 1998 . The areal extent of BTEX constituents from
petroleum hydrocarbons appears concentrated to an area around GP-4 which was a probe was
placed immediately south of the former underground storage tank (UST) in front of the W. P.
Ballard property along Rollins Road, as shown on Figure 15. The radial extent is less than 20

feet based on a soil sample from the 14 to 16 foot interval of BMW-1 which had no BTEX
detected, and a Geoprobe® soil sample from the 9 to 12 foot interval in GP-3, which also had no
reported BTEX constituents. The vertical extent of the petroleum hydrocarbon constituents in soil
extends to the water table in the area immediately north of Rollins Road delineated by
Geoprobe® probes GP-3, GP-4, and GPW-3.
The extent of soil VOC contamination is confined to the W. P. Ballard property with a possible
extension beneath Rollins Road to the south of the property. This finding is based on laboratory
analysis of a soil sample from BMW-1, soil gas levels, and the concentration of
Tetrachloroethene and its decay products in the groundwater.
The areal extent of petroleum hydrocarbon impacted groundwater appears to be limited to the
parking lot area in the southern half of the W. P. Ballard property, across Rollins Road to the
south, and on a small portion of the former SLS property. The lateral extent of the dissolved
BTEX plume is illustrated on Figure 15, Petroleum Hydrocarbon Investigation Geoprobe
Locations with Total BTEX Iso-Concentration Contours, a plot of the total BTEX
concentrations reported in the Geoprobe® water samples. The vertical extent of dissolved BTEX
constituents appears to be less than 25 feet due to the water samples from wells screened from
25 to 35 feet within plume delineated by the Geoprobe® water samples and in the immediate
vicinity, not reporting,,detectable levels of BTEX constituents in groundwater.
The extent of the dissolved phase chlorinated solvent plume has been delineated in three zones
in the aquifer; shallow (approximately 25 to 35 feet bgs), deep (approximately 60 to 85 feet bgs),
and in the bedrock. Figure 13 illustrates the areal extent of the dissolved VOC plume in the
shallow zone.
Figure 14 depicts the dissolved total VOC plume in groundwater from the 60 to 80 foot zone
beneath the site. This plume appears to have a similar "footprint" or areal extent to the shallow
zone plume. This is as expected considering the relatively uniform nature of the saprolite which
would tend to produce relatively uniform horizontal groundwater velocities with depth (i.e. no
stratified zones of more transmissive materials producing higher horizontal groundwater
velocities.
It does not appear that VOCs are extensively dispersed below the bedrock surface due to the
lack of water bearing fractures. The bedrock well groundwater sample analytical data and the
apparent absence of water bearing fractures in bedrock were used to support the vertical extent
delineation of the dissolved VOCs.
The migration of the VOC's in the shallow zone is strongly influenced by the groundwater flow
and reflects the easterly gradient as well as the southeasterly component in the gradient in the
Western portion of the site. [so -concentration contours have been depicted on Figure 6, Cross -
Section A -A' to illustrate the projected vertical extent of the dissolved total VOC plume along the
east -west axis (down -gradient) of the plume.

No free product was observed in any monitoring wells at the site. Petroleum hydrocarbon product
was not observed in any of the four temporary Geoprobe® wells but a strong petroleum odor was
noted in the bailer sample removed from GP-4. During the October 1999 sampling event, all
monitoring wells were checked for LNAPL and DNAPL with a Soilinst Interface probe when water
levels were taken prior to purging for sampling. No LNAPL or DNAPL accumulations were
detected.

1.0 INTRODUCTION
- The subject site is a former dry cleaning supply facility, located at 2701 Branchwood
Drive, approximately 400 feet east of Battleground Avenue in Greensboro, Guilford
County, North Carolina. Currently, the site is unoccupied. The site location is shown on
a portion of the United States Geological Survey 7.5-minute topographic map of
Greensboro, North Carolina Quadrangle, included as Figure 1, Site Location Map.
1.1 Objective of the Comprehensive Site Assessment (CSA)
This Comprehensive Site Assessment (CSA) has been prepared by IT Corporation of
North Carolina, on behalf of Sears Logistics Services, Inc (SLS). SLS is the former
owner of the downgradient property. SLS is remediating this site and performing these
assessment activities on behalf the W. P. Ballard (Ballard) as part of remediation
agreements between SLS and Ballard, and between SLS and the current owners of the
downgradient property.
The CSA has been designed to delineate adsorbed and dissolved phase volatile organic
compounds (mainly tetrachloroethene) present within the subsurface of the Ballard
property and surrounding properties. This CSA has been prepared in accordance with
the Groundwater Section Guidelines for the Investigation and Remediation of Soil and
Groundwater Volume 1, dated May 1998.
The site has been actively investigated since 1992. The following is a summary of
previous reports prepared and submitted to the NCDENR regarding the investigation of
the chlorinated solvent release at the W. P. Ballard property and surrounding properties:

1.2 Site Ownership History
The site ownership history is documented in Table 1, Property Ownership, W. P.
Ballard Property. The attached table lists property ownership since 1957, dates of
ownership, uses of the site and potential sources of contaminants.
1.3 Release Scenario and Source Characterization
The subject site was developed in 1957 as a dry cleaning supply and distribution facility,
operated by the WP Ballard and Company of Greensboro, Inc. (Ballard). From 1990 to
July 1999, Phenix Supply Company leased the site from Ballard. A petroleum
hydrocarbon release was discovered during the performance of underground storage
tank (UST) removal activities in September 1991. At the time of the discovery of the .
release, two 550-gallon USTs, one containing heating -oil and one containing gasoline,
were removed. The release was reported to have been associated with the former
gasoline UST. The estimated quantity and cause of this release are unknown. The
NCDENR was notified of the release in September 1991. There are currently no other
UST systems at the site.
To assess the extent of the petroleum hydrocarbon contamination, six monitoring wells
(MW-1 through MW-6) were installed on -site by Mortensen Engineering, Inc. (Mortensen)
in April 1992.. Laboratory analytical results for the groundwater samples collected from
monitoring wells MW-1 through MW-6 indicated the presence of high concentrations of
dissolved phase chlorinated solvents, consisting mainly of tetrachloroethene and its
associated breakdown products. Tetrachloroethene concentrations detected ranged from
11 ug/L (MW-5) to 270,000 ug/L (MW-3). The detected release is associated with
tetrachloroethene distribution activities that have historically been performed on site. The
estimated quantity of the PCE release or releases is unknown. The cause of the release
is also unknown. The release could have been caused by a leak or leaks from 55-gallon
drums stored on site and/or the 6000-gallon AST, from a spill during filling of the 6000-
gallon AST, or during filling of distribution trucks. In July 1999, the Phenix Supply
Company vacated the property and dry cleaning supply operations ceased. In August
1999, the 6000-gallon AST the formerly held bulk PCE was removed from the site. A
site map showing the former locations of the PCE AST and the gasoline UST is included
as Figure 2, Site Map.
1.4 Remedial Actions to Date
In September 1991, two 550-gallon USTs, one containing heating oil and one containing
', _i gasoline, were removed. Only the gasoline UST was found to have leaked.. In August
1999, the 6000-gallon AST that formerly held bulk PCE was removed from the site. No
j other remedial activities associated with the original petroleum hydrocarbon release nor
the later detected chlorinated solvent release have been performed to date.

In early 1999, IT Corporation performed an evaluation of remedial alternatives and
prepared a proposed Corrective Action Plan (IT Corporation, May 1999) for this site that
was submitted to NCDENR. The conceptual remedial design was prepared based on the
evaluation of remedial alternatives, and results of the pilot scale and bench scale testing
activities that had been performed in 1997, 1998 and 1999. A multi -phase approach is
proposed. The initial phase will consist of a comprehensive in situ oxidation application
event. The in situ oxidation will be performed by application of an oxidizer, sodium
permanganate, into the subsurface using direct push technology (Geoprobe). The
application of permanganate is expected to rapidly and aggressively oxidize the
chlorinated ethenes and significantly reduce their concentrations in soil and groundwater
at the site. Based on the results of the initial in situ oxidation event, a high -vacuum dual
phase (HVDP) groundwater extraction and treatment coupled with a low vacuum soil
vapor extraction (SVE) and treatment system will be designed and installed. The
purposes of the HVDP and low vacuum SVE systems are twofold. First, the system will
be designed to specifically address the source area and any adjacent areas where
elevated adsorbed and dissolved phase concentrations persist following the initial
oxidation event. Secondly, the groundwater and soil vapor extraction system will be used
" to augment future in situ oxidation events in impacted areas isolated from advective flow.
Implementation of the Phase 1 of this remedial approach is currently awaiting approval of
a UIC permit application by NCDENR.
1.5 Receptor Information
The subject site is located in a mixed commercial and residential area of Greensboro,
North Carolina. Surrounding property owners are listed on Table 2, List of Adjacent
Property Owners and shown on Figure 3, Adjacent Property Owners Map. On
November 18, 1998, field reconnaissance was performed within a 1,500-foot radius of the
site as part of a sensitive receptor survey performed by IT Corporation. The visual
reconnaissance did not identify domestic water supply wells within the specified radius.
The City of Greensboro Water Resources Department was contacted, and indicated that
municipal water supplied by the City of Greensboro is available in the vicinity of the
subject site. Water line and storm sewer location maps were copied and reviewed prior
to performing the site reconnaissance. Water meters and fire hydrants were evident
within 1,500 feet of the subject site.
Historic reports indicate that the closest downgradient surface water body is located to
the east-southeast of the site. Located approximately 1,000 feet from the subject site, on
the east side of Lawndale Avenue, is an unnamed intermittent tributary to Buffalo Lake.
Buffalo Lake is identified as a Class C nutrient sensitive waterway (NSW). At the time of
the field reconnaissance (November 18, 1998), the tributary was not observed to.be
flowing, and no standing water was observed.
Subsurface structures within 1500-feet of the release are shown on Figure 2, Site Map.
Potential man-made migration routes identified in the immediate vicinity of the site

include storm sewer lines located along Rollins Road, Branchwood Drive, along the
western portion of the former SLS property and along Lawndale Avenue. The storm
sewer lines located in the immediate vicinity of the site, along Rollins Road, appear to be
shallow and above the water table. The storm sewer lines located along the west -
northwest side of the remaining portion of the former Sears Logistics Services distribution
center appear to be installed at a greater depth, and likely intersect the groundwater
table.
No designated wellhead protection areas are located within 1,500 feet of the source area
of the release.
Currently the Ballard property is vacant and not being used. However, potential future
uses could be as an office, warehouse, manufacturing operation, distribution center or
other commercial activity. The adjacent properties are primarily commercial or light
industrial.
Activities that could potentially expose future on -site workers to impacted soil include:
dermal contact with.impacted surface soil by on -site workers; inhalation of vapors from
impacted surface soil by on —site workers, and; dermal contact with or ingestion of
impacted soil by on -site construction workers (a short-term exposure).
Since the area is served by public water supplies, on -site workers will not be exposed to
impacted groundwater through ingestion. However, activities that could potentially
expose future on -site workers to impacted groundwater include: dermal contact with or
ingestion of -impacted groundwater by on -site construction workers (a short-term
exposure).

2.0 CURRENT SITE AND SURROUNDING CONDITIONS
2.1 Regional Geology and Hydrology
The Ballard Property is situated in Guilford County, which is located within the Piedmont
Physiographic Province of North Carolina. Based on interpretations made from the
Geologic Map of North Carolina (Brown, Philip et. al., North Carolina Geologic Survey,
1985), the area is located in the Carolina Slate Belt geologic belt and is indicated to be
underlain by metamorphosed granitic rock. This was confirmed during drilling of bedrock
core -holes at the site that obtained core samples of Amphibolite Gneiss.
The regional groundwater flow in the vicinity of the site generally follows the surface
topography, is under unconfined conditions, and is free to rise and fall in response to
seasonal variations in recharge and discharge.
2.2 Site Geology and Hydrogeology
- Based on data collected during drilling operations, the subsurface stratigraphy consists of
Amphibolite Gneiss overlain by saprolite that consists of unconsolidated mixtures of
predominantly silt sized particles with varying amounts of sand and clay sized particles.
The saprolitic materials are generally characterized by micaceous silt with some sand
and retain the relict features of the parent rock; unconsolidated material with these
features is termed saprolitic. The saprolite can be separated into two zones based on
density or degree of weathering. The upper saprolite zone is soft to moderately
consolidated; and is delineated at depth by auger refusal occurring at depths ranging
between 45 and 79 feet with the average depth being approximately 69 feet. The lower
zone appears to be comprised of differentially weathered bedrock. Auger refusal and
slower rotary hammer drilling rates encountered at varying depths in the lower zone are
indicative of presence of pockets of less weathered bedrock above true bedrock
(undisplaced boulders) due to differential weathering. Based on observations made
during drilling, true, competent bedrock is concluded to exist at depths ranging from 105
to 123 feet below grade. Bedrock cored beneath the site was a very competent (few
fractures), light gray to dark green Amphibolite Gneiss. Other than the interface between
the unconsolidated overburden and the competent bedrock, significant lithologic changes
have not been observed in materials beneath the site.
To illustrate the subsurface. conditions beneath the site, several geologic cross -sections
have been prepared using boring logs generated during the installation of onsite
monitoring wells. A site map showing the locations of cross-section lines is included as
Figure 5, Cross Section Location Map. Cross -sections, A -A', B-B' and B-B", C-C' and
C-C", and D-D' are included as Figures 6 through 11, respectively. Boring and well
construction logs for wells included in the cross sections are included in Appendix A and
locations of monitoring wells are illustrated on Figure 4, Monitoring Well Location Map.

Monitoring well data indicate that, the depth to groundwater follows the regional trend
across the site and ranges from 4.02 to 28.44 feet below grade. Wells exhibiting the
shallowest depth to groundwater measurements (e.g., MW-13, MW-17, DW-8 and DMP-
4) are located in 'cut' areas, where the natural topography was excavated to
accommodate the former Sears Logistics Services facility. Data collected during the
most recent well sampling performed October 25 through 27, 1999 are presented in
Table 3, Groundwater Gauging and Water Table Elevation Summary. A water table
elevation contour map prepared with data from the October 1999 gauging and sampling
event, is included as Figure 12, Water Table Elevation Contour Map.
Variations in the groundwater surface elevation generally correspond with changes in the
natural topography. This is demonstrated most effectively by the water table surface in
the northwestern corner of the site. In this area, the water surface gradient has a vector
to the south and east which reflects the influence of the topographic high that is just
northwest of the corner of the site. The predominant groundwater flow direction at the
site is to the east with an average hydraulic gradient of 0.023 feet -per -foot.
The groundwater flow patterns on the site have a demonstrable influence on the
migration of the chlorinated solvent plume. As shown on Figure 13, Iso-Concentration
Contours of Total Volatile Organics — Shallow Zone and Figure 14, Iso-
Concentration Contours of Total Volatile Organics — Deep Zone, the main portion of
the plume trends east influenced by the predominant gradient and a minor perturbation of
the plume flows to the southeast influenced by the southern vector of the gradient found
in the western portion of the site.
2.2.1 Soil Sampling Results
During drilling of monitoring wells and Geoprobe® core sampling conducted from
September 29 to October 21, 1999, soil samples were taken for laboratory analysis.
Samples analyzed were obtained from the zone above the water table. The analytical
method for each sample was dependent on the chemicals of concern, hydrocarbons or
chlorinated solvents, and is indicated in the section below that describes the results of
each investigation.
2.2.1.1 Soil Sampling Activities
Soil sampling to delineate the extent of petroleum hydrocarbons in soil for the
Comprehensive Site Assessment (CSA) investigation was performed September 29 and
30, 1999 and involved obtaining soil samples using a MacroCore® core sampler in
Geoprobe® probes GP-1, -2, -3, and —4. The probes were located on the W. P. Ballard
property and the former SLS property as shown on Figure 15, Petroleum Hydrocarbon
Investigation Geoprobe® Locations with Total BTEX Iso-Concentration Contours.
All probes were advanced to a depth of 20 feet below ground surface to assure
penetration of the groundwater/vadose zone interface. At the four (4) probe locations

(GP-1, -2, -3, and —4) continuous soil samples were collected using a MacroCore
sampler from ground surface to termination. Soil samples were field screened with a
Photo Ionization Detector (PID) to select an individual sample from the vadose zone from
each point for laboratory analysis. The soil sample with the highest PID reading from
- each of the four probes was sent to be analyzed by EPA Method 8260+MTBE+IPE, EPH
& VPH, and EPA Method 8270.
Monitoring wells DW-13, -14, and —15 and BMW-1, -2, -3, and -4 were drilled as part of
the recent investigation, primarily to evaluate the extent of chlorinated solvents in
groundwater. In the pilot (surface casing) boreholes for these Type III wells, soil samples
were obtained using split -spoon samplers. Split -spoon samples were not taken in
boreholes for wells BMW-2 and DW-14 because they were drilled in close proximity to
wells BMW-1 and BMW-4, respectively, and these wells had already been sampled. In
sampled boreholes, soil samples were collected at five-foot intervals from the ground
surface to the top of competent bedrock or auger refusal in each monitoring well
borehole. All split -spoon soil samples were visually inspected to note color, texture/grain
size, apparent solvent odor or staining, and moisture. In accordance with the Additional
Assessment Activities plan, only split spoon samples from drill hole BMWA were field
screened using a PID and the soil sample exhibiting the highest response collected from
above the water table submitted for laboratory analysis by EPA Method 8260.
2.2.1.2 Hydrocarbons
Laboratory analytical information for samples taken to investigate the extent of
hydrocarbons in soil is presented in Table 4, Summary of Soil Analytical Data —
Geoprobe® Investigation. Based on field and analytical data, hydrocarbon constituents
in soil appear to be limited in areal extent and are less than the Commercial -Industrial
standards published by NCDENR in 1998. BTEX constituents, benzene, toluene, and
xylene, were detected in only one Geoprobe® soil sample from the 9 to 12 foot interval of
GP-4. This probe was placed immediately south of the former underground storage tank
(UST) in front of the W. P. Ballard property along Rollins Road, as shown on Figure 15.
The areal extent of petroleum hydrocarbons in soil is substantiated by the following soil
samples taken within a 20 foot radius of GP-4.
• A soil sample from the 14 to 16 foot interval of BMW-1, a monitoring well
approximately 20 feet north of GP-4, had no detections reported for BTEX
constituents in the soil.
• Similarly the Geoprobe® soil sample from the 9 to 12 foot interval in GP-3,
approximately 20 feet east of GP-4, had no reported BTEX constituents.
The vertical extent of the petroleum hydrocarbon constituents in soil extends to the, water
table in the area immediately north of Rollins Road delineated by Geoprobe® probes
GP-3, GP-4, and GPW-3.

2.2.1.3 Chlorinated Solvents
Laboratory analysis of a soil sample from the 14 to 16 foot interval in BMW-1 indicated
the presence of Tetrachloroethene at 39.06 mg/kg (reported as 0.7812 mg/kg @ dilution
factor of 50) and 1,1,2-Trichloroethane at 0.0045 mg/kg. This information coupled with
soil gas levels, depicted on Figure 17, Soil Gas Survey Baseline VOC Iso-
Concentration Contour Map, and the concentrations of Tetrachloroethene and its decay
products in the groundwater suggest that the chlorinated solvent soil contamination is
confined to the W. P. Ballard property with a possible extension beneath Rollins Road to
the south of the property.
2.2.2 Soil Vapor Sampling Results
The laboratory analytical results from the January 20 and 27 and November 19, 1999 soil
vapor sampling events indicate that chlorinated compound concentrations were detected
in soils immediately south of the buildings on the W. P. Ballard property. Compounds
detected include: 1,1,2-trichloroethane; chloroform; tetrachloroethene; trichloroethene;
1,2-dichloroethane; cis- 1,2-d ich loroethene; and 1,1-dichloroethene. Tetrachloroethene
concentrations detected ranged from 57,000 mg/m3 in SVMP-2 to <250 mg/m3 in SVMP-
6. Summaries of the baseline and current soil vapor monitoring results are included as
Table 5, Summary of Soil Vapor Monitoring Point Test Data. Results for the January
20 and 27, 1999 sampling events were averaged to calculate a baseline total VOC soil
vapor concentration and the November 19, 1999 data are compared to this established
baseline. A soil vapor total VOC isoconcentration map that presents the baseline data is
included as Figure 17, Soil Gas Survey Baseline VOC Iso-Concentration Contour
Map.
2.2.2.1 Soil Vapor Monitoring Point Installation
During the week of January 4, 1999, twelve soil vapor monitoring points (SVMP-1
through SVMP-12) were installed on the W. P. Ballard property at the locations shown on
Figure 16, Soil Vapor Monitoring Point'Locations. These soil vapor monitoring points
were placed in a grid pattern across the source area to monitor soil vapor concentrations
throughout the remediation process. Each of the soil vapor monitoring points was
advanced to a depth of 12 feet below ground surface, and constructed with a 10-foot
section of 0.020-inch slot Schedule 40 PVC screen and a 2-foot section of Schedule 40
PVC riser. The annular -space around the screen was backfilled with filter sand to
approximately 0.5 feet above the screen. The annular space above the sand pack was
backfilled with a bentonite seal to approximately 0.5 feet from ground surface. Each soil
vapor monitoring point was secured with an expandable, lockable cap, and finished at the
surface with a bolt -down, flush -mount cover set in a 2'x2' concrete pad. Well construction
records and boring logs are included in Appendix A.
2.2.2.2 Soil Vapor Sampling
On November 19, 1999 soil vapor extraction wells SVMP-1 through SVMP-12 were
sampled. The wells were sampled by removing the well cap, and installing a temporary
(tri-seal) well head adapter. Each well was then field screened for VOC concentrations

using a photoionization detector (PID) prior to purging. A Gast vacuum pump was
connected to the well head adapter using polyethylene tubing, with new tubing being
used at each point. Using the Gast vacuum pump, three boring volumes of soil vapors,
or approximately 28.5 W, were evacuated from each well at a maximum flow rate of 1.5
- cfm. Purged soil vapors were field screened using a PID following the evacuation of
each well boring volume. Following purging, the vacuum pump was disconnected and the
well was allowed to equilibrate for a minimum of five minutes. The soil vapor total VOC
concentrations were again field screened using a PID and an air bag sample was
collected at each point. Air samples were shipped via overnight courier to Micro -Seeps,
Inc., in Pittsburgh, Pennsylvania for the analysis by Method AM 4.03 - for the Method 601
Compound List. Soil vapor monitoring point purging data are presented in Table 6, Soil
Vapor Monitoring Point Purging Data.
2.2.3 Groundwater Sampling Results
Results of the groundwater sampling activities performed October 25 through 28, 1999,
during the CSA investigation, indicated detectable concentrations of halogenated and
aromatic volatile organic compounds (VOCs), semi -volatile organics to be present
beneath and down gradient of the W. P. Ballard property. Of the compounds detected in
the monitoring well and Geoprobe® groundwater samples; Benzene, Ethylbenzene,
Toluene, Xylenes, Bromoform, Ethylene Dibromide, Carbon Tetrachloride, Chloroform,
Vinyl Chloride, 1,1-Dichloroethane,1,2-Dichloroethane, 1,1-Dichloroethene, cis-1,2-
Dichloroethene, 1,2-Dichloropropane, Tetrachloroethene, and Trichloroethene were
detected above the current 2L standards.
2.2.3.1 Well Construction and Sampling Activities
Monitoring well construction for the CSA investigation was conducted from September 30
to October 21, 1999 to expand the groundwater monitoring network in the intermediate
(60 to 80 feet below ground surface (bgs)) and deep/bedrock zones. The aquifer
beneath the site appears to be unconfined but due to its thickness has been divided into
shallow (25 to 35 bgs), intermediate (60 to 80 feet bgs), and deep or bedrock (>100 feet
bgs) zones. Previous investigations by Mortensen Engineering and IT Corporation
resulted in the construction of 32 wells in the shallow and intermediate zones. Seven of
the 32 wells have been destroyed by construction on the former SLS property. The
seven (7) CSA investigation wells, described in the following paragraph, were intended to
expand the existing monitoring well network to achieve areal and vertical delineation of
the chlorinated solvent plume.
To attempt to delineate the areal extent of the chlorinated plume, three Type II monitoring
i
wells (DW-13, -14, and —15) were completed to a total depth of 65 feet below grade at
- locations indicated on Figure 4, Monitoring Well Location Map. Each well was
constructed using 50 feet of 2-inch ID, 0.010 slot, Sch. 40 PVC manufactured screen with
threaded joints and 15 feet of 2-inch ID, Sch. 40 PVC well casing with threaded joints. A
sand filter pack was installed to a depth equivalent to two feet above the top of the well
14

screen. A bentonite seal consisting of three feet of hydrated bentonite was installed on
top of the sand filter pack. The remaining borehole annulus was backfilled with a
Portland cement/bentonite slurry. Each well was completed with a 2 ft. by 2 ft. concrete
pad and flush mount, traffic rated, bolt down cover.
Four (4) deep zone or bedrock Type III monitoring wells (BMW-1, -2, -3 & -4) were
installed at locations indicated on Figure 4 to attempt to delineate the vertical extent of
the chlorinated solvent plume. During drilling in the unconsolidated materials, split spoon
samples were collected every 5 feet in each of the drill holes to characterize the
materials. Drilling continued five (5) feet into competent bedrock and then a 6-ID steel
surface casing was installed to the total depth and grouted in place. After the grout had
set (at least 24 hours), rock coring or drilling proceeded to the target depth. In two of the
drill holes, BMW-1 and —3, continuous core samples were collected to observe the
,bedrock characteristics. Core samples were not taken in BMW-2 because it was drilled
adjacent to BMW-1 and the subsurface information from BMW-1 was used to determine
the total depth of the well constructed. BMW-4 was also not cored due to it being
decided during drilling that the monitoring well at that location was to be constructed in
the near bedrock "rubble" zone that appeared to be a relatively high yield zone for
groundwater.
To facilitate monitoring well construction in coreholes, at the completion of coring the
corehole was reamed with an air hammer to approximately 5.25 inches. After reaming or
drilling to the target depth , monitoring wells were constructed of 2-inch ID Sch. 40 PVC
well casing with 0.010 slot screen at lengths of 5 to 20 feet, dependent upon subsurface
conditions noted during coring or drilling. A sand filter pack was installed to a depth
equivalent to two feet above the top of the well screen. A bentonite seal consisting of
hydrated bentonite was installed from the top of the sand filter pack to at least five (5) feet
above the top of the surface casing. The remaining borehole annulus was backfilled with
a Portland cement/bentonite slurry. Each well was completed with a 2 ft. by 2 ft. concrete
pad and flush mount, traffic rated, bolt down cover.
At the completion of well construction, the wells were developed by purging and surging
until the water was relatively clear, and conductivity and pH were indicative of formation
fluids (i.e., three consecutive pH and Conductivity readings taken after purging in five to
'f ten gallon increments are within ±0.1 pH units and ±10%, respectively). After well
development the wells were allowed to recover for at least 48 hours, then water samples
were taken after purging at least three (3) well volumes, or, if the well purged dry, after
recovery to 80% of the pre -purging water level. Groundwater samples were sent to the
laboratory for analysis by EPA Method 8260.
Well construction details are provided in boring logs enclosed in Appendix A and are
summarized in Table 7, Well Construction Summary. Well purging and sampling

information is summarized in Table 8, Summary of Groundwater Sampling Field
Parameters. To qualitatively evaluate the subsurface hydrogeology, the following
observations were made during coring:
1. Drilling fluids used during coring are unchanged, losing, lost, or gaining during coring;
2. Coring rate changes or sudden step changes in depth indicating fractures;
3. Changes in water recovery at each fracture encountered also noting depth that core
bit was at when fracture first detected; and
4. Core samples were observed to note fracture orientation relative to vertical and
aperture, in -filling, or discoloration of fractures.
Observations are noted on the Boring Logs attached in Appendix A.
2.2.3.2 Hydrocarbons
The source of petroleum hydrocarbons was a gasoline UST previously located on the W.
P. Ballard property. Evaluation of the hydrocarbon constituent plume was accomplished
using information from a total of eight (8) Geoprobe0 points installed on the W. P. Ballard
property and the former SLS property. The probes were advanced to a depth of 20 feet
below ground surface to assure penetration of the vadose/saturated zone interface and a
groundwater sample collected from each probe point and analyzed by EPA Method 601,
EPA Method 602+MTBE+IPE, and VPH & EPH.
Laboratory analytical information for groundwater samples taken to investigate the extent
of dissolved hydrocarbons is presented in Table 9, Summary of Groundwater
Analytical Data - Geoprobe0 Investigation. The areal extent of petroleum
hydrocarbon impacted groundwater appears to be limited to the parking lot area in the
southern half of the W. P. Ballard property, across Rollins Road to the south, and on a
small portion of the SLS property. The lateral extent of the dissolved BTEX plume is
illustrated on Figure 15, Petroleum Hydrocarbon Investigation Geoprobe Locations
with Total BTEX [so -Concentration Contours, a plot of the total BTEX concentrations
reported in the GeoprobeO water samples. The vertical extent of dissolved BTEX
constituents appears to be less than 25 feet due to the water samples from wells
screened from 25 to 35 feet within plume delineated by the Geoprobe0 water samples
and in the immediate vicinity, not reporting detectable levels of BTEX constituents in
groundwater.
2.2.3.3 Chlorinated Solvents
The extent of the dissolved phase chlorinated solvent plume has been delineated in three
zones in the aquifer; shallow (approximately 25 to 35 feet bgs), deep (approximately 60
-, to 85 feet bgs), and in the bedrock. The source of information for making this delineation
is data collected during the CSA investigation conducted in September and October of
1999 by IT Corporation of North Carolina, Inc.
Groundwater analytical data from monitoring wells sampled October 25 through the 28,
1999 are presented in Table 10, Summary of Shallow Monitoring Well Groundwater

Analytical Data and Table 11,•Summary of Deep Monitoring Well Groundwater
Analytical Data. Data from Tables 10 and 11 are used to prepare iso-concentration
contour maps of Volatile Organic Compound (VOC) plumes in the shallow and deep
zones as shown on Figures 13 and 14. Figure 13 illustrates the areal extent of the
dissolved VOC plume in the shallow zone. The plume extends approximately 1500 feet
to the east and approximately 540 feet to the southeast and is delineated by non -detect
wells on all sides except at the distal end of the plume. The reported VOC level at MW-
23 which is the well at the distal end of the plume is 3.6 ug/1 and thus the extrapolated
zero contour is assumed to pass just east -of MW-23 and be well within the bounds of the
former SLS property. The migration of the VOC's in the shallow zone are strongly
influenced by the groundwater flow and reflect the easterly gradient as well as the
southeasterly component in the gradient in the western portion of the site. The southerly
extent of the shallow plume is also thought to be influenced by a possible, much smaller
release, of Trichloroethene (TCE) near the southeastern corner of the building across
Rollins Road from the W. P. Ballard property on the former SLS property. This is thought
to be a separate release because the reported VOC in MW-27, the well near the possible
release location, is primarily TCE.
Figure 14 depicts the dissolved total VOC plume in groundwater from the 60 to 80 foot
zone beneath the site. This plume appears to have a similar "footprint" or areal extent to
the shallow zone plume. This is as expected considering the relatively uniform nature of
the saprolite which would tend to produce relatively uniform horizontal groundwater
velocities with depth (i.e. no stratified zones of more transmissive materials producing
higher horizontal groundwater velocities). The delineation of the zero line for most of the
plume is based on extrapolating the trend developed by inner contours. However, the
distal end of the intermediate zone plume does have a non -detect well, DW-12, to define
the eastern extent at the property line.
The bedrock well groundwater sample analytical data and the apparent absence of
groundwater in bedrock were used to support the vertical extent delineation of the
dissolved VOCs. BMW-1, the bedrock monitoring well in the source area, was screened
from 130 to 150 feet bgs and is dry. BMW-2, a monitoring well completed at the bedrock
saprolite interface within 15 feet of BMW-1, is screened from 95 to 115 feet bgs. The
water sample analysis from BMW-2 reported 48,800 ug/1 of Tetrachloroethene and no
other VOCs. The water sample analysis from BMW-3, a bedrock well nested with MW-12
and DW-7 and screened from 123 to 143 feet bgs, reported 260 ug/I of Tetrachloroethene
and 18 ug/1 of additional VOCs. Based on this information it is concluded that in the
source area the bedrock at the 130 to 150 foot bgs horizon is not transmissive (i.e.,
fractures are few and/or do not allow fluid migration) and thus the zero level for VOCs is
between 115 and 130 feet bgs. Considering the conditions observed at the BMW-
1/BMW-2 location, it is assumed that the bedrock below BMW-3 (below 143 feet bgs)
becomes less transmissive rapidly and the VOC zero line is somewhere is the vicinity of
17

150 feet bgs. This is also substantiated by the observation that core from BMW-3 was
generally unfractured, similar to the core from BMW-1, and only had one weathered
fracture noted from 126.3 to 126.4 feet bgs. Iso-concentration contours have been
depicted on Cross -Section A -A' to illustrate the projected vertical extent of the dissolved
total VOC plume along the east -west axis (down -gradient) of the plume.
2.2.4 Free Product Investigation Findings
Four of the eight Geoprobe® probes were converted into temporary monitoring wells by
installing 1.25-inch ID PVC well casing with a 10 foot, 0.010 slot well screen on the
bottom to total depth of the probe. The four temporary monitoring wells were allowed to
stand for a period of 17 days to monitor for the presence of liquid phase hydrocarbons
(LPH), and were properly abandoned after being checked for LNAPL using a bailer.
Product was not observed in any of the four temporary wells but a strong petroleum odor
was noted in the bailer sample removed from GP-4.
During the October 1999 sampling event, all monitoring wells were checked for LNAPL
and DNAPL with a Soilinst Interface probe when water levels were taken prior to purging
for sampling. No LNAPL or DNAPL accumulations were detected.
2.2.5 Hydrogeologic Investigation
Aquifer tests were completed during remedial pilot testing conducted between September
10, 1997 and September 18, 1997. Pilot test activities were performed by IT Corporation
in the water table aquifer at the site to evaluate the feasibility of remediation options to be
used at the site. As part of the pilot testing, an aquifer test was performed, in which
groundwater was extracted and aquifer response was measured. The aquifer test was
performed under several conditions: vacuum enhanced vs. non -vacuum enhanced,
variable flow rates, multiple pumping wells, etc. As such, traditional data reduction
methods could not be employed to evaluate the data. However, examination of these
data does provide useful insight into the subsurface conditions, as well as, the
characteristics of the aquifers at the site. Data used for the following interpretation of site
hydrogeologic conditions are included in Appendix B.
Data reduction for two wells will be discussed here. Well EW-2 is a "shallow" well,
installed to a total depth of 25 feet below grade. Well EW-3 is a "deep" well, installed to a
total depth of 65 feet below grade. Water level recovery data for these wells were input
into the Bouwer and Rice formula, using the AQTESOLV data reduction program. Data
reduction resulted in the following average horizontal hydraulic conductivity values for the
screened intervals of each well:
EW-2: Kh = 0.60 ft/day
EW-3: Kh = 8.11 ft/day
18

IT Corporation ofNortn Cam nma, Inc.
A Member of The /T Group
Comprehensive Site Assessment Report
W. P. Ballard and Downgradient Properties December 16, 1999
These values were compared to typical values of horizontal hydraulic conductivity for
aquifer materials. It was concluded that these estimated values fall within the typical
ranges for sand and silt aquifers. Note that well EW-3 has a higher estimated horizontal
hydraulic conductivity. The screened interval for this well was installed near the top of
bedrock. The higher hydraulic conductivity in this well is likely attributed to a zone of
coarse particles (partially weathered rock) near the top of bedrock.
The average horizontal hydraulic conductivity was calculated to be 2.20 ft/day for the
entire thickness of the aquifer. Since the aquifer is saprolitic in nature (e.g. result of in -
place weathering not deposition), the average vertical hydraulic conductivity of the aquifer
is assumed to be 0.5 that of the horizontal hydraulic conductivity. As such, the overall
average hydraulic conductivity of the aquifer is estimated to be approximately 1.55 ft/day.
The groundwater gradient is estimated to be 0.023 feet -per -foot across the site.
Assuming a porosity of 0.3 and using the average horizontal hydraulic conductivity (2.20
ft/day), the average linear groundwater velocity across the site is 0.17 feet/day. Average
linear groundwater velocity is calculated using the following formula:
conductivity
V = [ i Kh ]/ne where: V = average linear velocity
i = hydraulic gradient
Kh = horizontal hydraulic
ne = effective porosity
Transmissivity of the aquifer may be estimated by the following equation:
T = Kh * b where: T = transmissivity
Kh = horizontal hydraulic conductivity
b = aquifer thickness
Using an average Kh of 1.55 feet per day, and an average aquifer thickness of 55 feet
(ground surface to top of bedrock), the aquifer transmissivity is estimated to be 85.25 feet
squared per day.

3.0 DISCUSSION OF FINDINGS
Subsurface data collected during drilling operations indicates that the site stratigraphy
consists of Amphibolite Gneiss overlain by saprolite that consists of unconsolidated
mixtures of predominantly silt sized particles with varying amounts of sand and clay sized
particles. The Amphibolite Gneiss bedrock is very competent (few fractures), light gray to
dark green and was encountered at depths ranging from 105 to 123 feet below grade The
saprolite can be separated into two zones based on density or degree of weathering. The
upper saprolite zone is soft to moderately consolidated and is delineated at depth by
auger refusal occurring at depths ranging between 45 and 79 feet with the average depth
being approximately 69 feet. The lower zone appears to be comprised of differentially
weathered bedrock and has been defined based on depths at which auger refusal and
slower rotary hammer drilling rates were encountered. Other than the interface between
the unconsolidated overburden and the competent bedrock, significant lithologic changes
have not been observed in materials beneath the site.
Subsurface exploration indicates that the saprolite is saturated below a depth ranging
from 7 to 28 feet below ground surface and in a very limited number of fractures in the
bedrock allow groundwater to penetrate to an undetermined depth in at least one
location. Due to the limited fracturing observed in cores and the lack of apparent
weathering in observed fractures,. it is concluded that the bedrock is not a conduit for
groundwater. The saprolite aquifer beneath the site is unconfined and the water surface
elevations generally correspond with changes in the natural topography. The
predominant groundwater flow direction at the site is to the east with an average
hydraulic gradient of 0.023 feet -per -foot and the average hydraulic conductivity is 1.55
ft/day. Hydraulic conductivity varies significantly between the shallow and deep saprolite
zones due to the degree of weathering of the in -place materials.
Hydrocarbon constituents in soil appear to be limited in extent. The areal extent of BTEX
constituents from petroleum hydrocarbons appears concentrated to an area around GP-4
which was a probe was placed immediately south of the former underground storage tank
(UST) in front of the W. P. Ballard property along Rollins Road, as shown on Figure 15.
The radial extent is less than 20 feet based on a soil sample from the 14 to 16 foot
interval of BMW-1 which had no BTEX detected, and a Geoprobe® soil sample from the
9 to 12 foot interval in GP-3, which also had no reported BTEX constituents. The vertical
extent of the petroleum hydrocarbon constituents in soil extends to the water table in the
area immediately north of Rollins Road delineated by Geoprobe® probes GP-3, GP-4,
and GPW-3.

The extent of soil VOC contamination is confined to the W. P. Ballard property with a
possible extension beneath Rollins Road to the south of the property. This finding is
based on the following:
i
• A laboratory analysis of a soil sample from the 14 to 16 foot interval in BMW-1,
• soil gas levels, depicted on Figure 17, Soil Gas Survey Baseline VOC Iso-
Concentration Contour Map, and
• the concentrations of Tetrachloroethene and its decay products in the groundwater.
The areal extent of petroleum hydrocarbon impacted groundwater appears to be limited
to the parking lot area in the southern half of the W. P. Ballard property, across Rollins
Road to the south, and on a small portion of the former SLS property. The lateral extent
of the dissolved BTEX plume is illustrated on Figure 15, Petroleum Hydrocarbon
Investigation Geoprobe Locations with Total BTEX Iso-Concentration Contours, a
plot of the total BTEX concentrations reported in the Geoprobe® water samples. The
vertical extent of dissolved BTEX constituents appears to be less than 25 feet due to the
water samples from wells screened from 25 to 35 feet within plume delineated by the
Geoprobe® water samples and in the immediate vicinity, not reporting detectable levels
of BTEX constituents in groundwater.
The extent of the dissolved phase chlorinated solvent plume has been delineated in three
1,
zones in the aquifer; shallow (approximately 25 to 35 feet bgs), deep (approximately 60
to 85 feet bgs), and in the bedrock. Figure 13 illustrates the areal extent of the
dissolved VOC plume in the shallow zone.
Figure 14 depicts the dissolved total VOC plume in groundwater from the 60 to 80 foot
zone beneath the site. This plume appears to have a similar "footprint' or areal extent to
the shallow zone plume. This is as expected considering the relatively uniform nature of
the saprolite which would tend to produce relatively uniform horizontal groundwater
velocities with depth (i.e. no stratified zones of more transmissive materials producing
higher horizontal groundwater velocities.
The bedrock well groundwater sample analytical data and the apparent absence of water
bearing fractures in bedrock were used to support the vertical extent delineation of the
dissolved VOCs.
The migration of the VOC's are strongly influenced by the groundwater flow and reflect
the easterly gradient as well as the southeasterly component in the gradient in the
i western portion of the site. Iso-concentration contours have been depicted on Figure 6,
Cross -Section A -A' to illustrate the projected vertical extent of the dissolved total VOC
plume along the east -west axis (down -gradient) of the plume.

No free product was observed in any monitoring wells at the site. Petroleum hydrocarbon
product was not observed in any of the four temporary Geoprobe® wells but a strong
petroleum odor was noted in the bailer sample removed from GP-4. During the October

4.0 CONCLUSIONS AND RECOMMENDATIONS
It is concluded that the objectives of the Comprehensive Site Assessment (CSA) have
been met in that the extent of CoCs in soil and groundwater have been fully delineated.
In addition, analytical data indicate that petroleum hydrocarbon concentrations in soil
around the source area, the former UST location on the WP Ballard property, are less
than the NCDENR Commercial -Industrial standards.

GREENSBORO, NORTH CAROLINA
EA_ GENERA
The pilot test was conducted from September 10, through September 18, 1997. The test consisted of a
Step Test, Pump -Vent Test, Sparge Test, Sparge-Vent Test, and a Pump Vent Test - EW-1 and EW-2.
The pilot test used 10 monitoring wells and 4 extraction wells to conduct and monitor the test. The layout
of the extraction and monitoring wells are presented on Figure 1. The vacuum systems used for the pilot
test consisted of a Rotron blower (System 1), connected to EW-1 and EW-2, and a Venturi (System 2),
connected to EW-3 and EW-4.
The following sections present the data recorded during the pump test.

A short Pump -Vent Test was conducted on EW-1 and EW-2 on September 18, 1997. The purpose of this
test was to use the two best pumping wells (EW-1 and EW-2) and the venturi to see what the maximum
removal rate could be. The venturi was moved from EW-3 and EW-4 and installed on
EW-1 and EW-2.

F
- shows EW-1 and EW-3 drawdown and recovery
A - Shows drawdown in recovery wells EW-2 and EW-4 exceeding the transducer
depth.
- Also shows pumping activities in EW-3 and EW-1 vacuum.
Wells recharged to pre -pumping levels within approximately 4 to 5 hours.
B - Shows same information as Chart A but only out to 720 minutes.
C - Shows same information as Chart Abut only out to 510 minutes.
D - Shows recovery wells EW-2 and EW-4 during pumping and recharge.
Note: rebound of 2.4 and 4 feet for above pre -pumping levels.
E - Shows wells EW-2 and EW-4 for pumping events (not "recovery" event).
F - Shows wells EW-1 and EW-3. Well EW-1 seems to have been disconnected
from the data logger while well EW-3 data was colleted and shows recovery in
approximately one hour.
- Deeper wells recovered a lot quicker than shallower wells.
- Drawdown at 110 minutes shown on contour map and graph.
- Specific capacity shown on page 1.
- Two distance drawdown graphs were generated from Step Test data and are
shown on pages 2 and 3.

PUMP AND VENT TEST (wells EW-2 & EW-4)
Graphs of G - all data logger data d 9 full test r
H - pumping well data for full test
I - observation well data for full test
J - pumping wells and wells PT-2S and PT-3S
G - Shows pumping and recovery events.
H - Water levels in well EW-2 periodically exceeded the depth of the transducer and
then were allowed to periodically recover. Water levels in EW-4 show "stepped"
drawdown.
I - Showed increasing water levels in well PT-21D and PT-3D. Well 2S transducer
problem. Wells 2S and 3S showed response/drawdown.
J - Shows recovery wells and corresponding wells that showed response to
pumping of EW-2 and EW-4.

PUMP -VENT TEST - ALL FOUR EXTRACTION WELLS PUMPING

Pumping Data

PUMPING EW-1, EW-2, EM & EW-4
Graphs of K - all data logger data for entire test
L - recovery wells EW-1 and EW-3 and response of PT-313 to pumping
K - Shows very limited drawdown of shallow wells in response to pumping and good
response of 3D to pumping.
L - Shows drawdown response of well 3D to pumping EW-1 but data from 1600 to
3040 minutes is anomalous from 1600 to 3040 minute observation levels are
deeper than pumping wells possibly due to XD problems.
M - When 25 feet of drawdown in EW-1 gets 8 feet of drawdown in 3D which is 34
feet away.
Contour map may not be accurate.
Data seems problematic.
