CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 1 April 3, 2020
1 INTRODUCTION
Geosyntec Consultants of NC, P.C. (Geosyntec) prepared this Limited Groundwater and Saturated
Soil Assessment Report (Report) on behalf of the Prospective Developer (PD), Merritt – IB1, LLC,
for the TW Alexander – IBM property located at 1 TW Alexander Drive, 3252 & 3260 S. Miami
Boulevard, and 1001 Hill Drive (formerly addressed as 0 TW Alexander Drive 0, 3102, 3204,
3252, 3268 S. Miami Boulevard) in Durham, Durham County, North Carolina (herein referred to
as the “Subject Site”, “Site” or “Brownfields Property”). The Subject Site is comprised of Durham
County Parcel Identification Numbers (PINs) 0749-03-31-9242, 0749-03-41-4159, 0749-04-51-
1176, 0749-04-50-1918, 0749-03-40-3468, and 0748-01-49-4407 and consists of +/- 51.15 acres
of land. The Subject Site is identified as North Carolina Brownfield Program (NCBP) No. 23016-
19-032. A Brownfields Agreement (BFA) was finalized on 23 December 2019. The Subject Site
is depicted on Figure 1.

The Brownfield Property was historically used for agricultural and residential purposes and
currently consists of undeveloped woodland. The PD purchased the Subject Site from IBM on 16
January 2020.

Proposed redevelopment of the Brownfields Property by the PD includes the construction of four
flex buildings for no uses other than industrial, office, or retail with associated parking (NCDEQ,
2019c). The current redevelopment schedule, beginning with vegetation clearing and installation
of erosion and sediment control measures is targeted for April 2020. Site grading and earthwork
is currently scheduled to begin at the end of April / beginning of May 2020 and last through
October 2020. Building construction will follow site grading, with occupancy targeted for January
2021.

Current grading plans indicate a net import project of an estimated 25,000 cubic yards of suitable
soil and stone aggregate. Plans indicate that it is unlikely that soil will need to be excavated and
exported off-site for disposal unless it is geotechnically unsuitable soil that cannot be amended for
on-site use.

The proposed stormwater system will reportedly be the deepest utility at the Site located at
approximately 13 feet below the current land surface at its deepest point. Three lined stormwater
ponds ranging in depth from approximately 4 to 14 feet below the current land surface are also
proposed to control drainage from the Site.

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 2 April 3, 2020
The redevelopment, overall grading, and storm drainage plan is depicted on Figure 2. Figure 2
also provides the location of monitoring wells that were installed as part of this assessment as
described in the following sections of this report.

Based on groundwater data reported by others, depth to groundwater is variable and the data
suggests the potential for groundwater to be encountered within five feet below the current land
surface (Amec Foster Wheeler, 2018). Due to the characteristics of the underlying geology,
groundwater elevation data from previous groundwater monitoring events may not accurately
depict the depth at which construction activities may encounter groundwater. As described in the
following section of this report, groundwater beneath the Site has been impacted from an off-site
chlorinated solvent release. Based on available data, this information suggests the potential to
encounter a contaminated water table during site construction activities.

The objectives of the investigation described in this Report are to: 1) further evaluate the potential
for construction activities to encounter impacted groundwater and saturated soil during
construction; and 2) support development of site design and construction strategies to limit and
manage potential dewatering and management of soils excavated below the water table. To meet
this objective four groundwater monitoring wells were installed on the Site in deep construction
areas to obtain additional information regarding the actual depth to groundwater in relation to
proposed deep construction excavation areas. The scope of work also included the collection of
soil samples from the bottom of the monitoring well borings to evaluate the potential presence of
contaminants of concern (COCs) in soils that would be disturbed during site construction activities.
1.1 Site Environmental History
The Brownfields Property is located downgradient of a volatile organic compound (VOC) (i.e.,
[chlorinated] solvent) plume that originates on the north adjacent former Edward Weck, Inc.
facility (EPA ID NCD 001 493 931) located at 2917 Weck Drive in Durham, North Carolina.
Corrective Action activities for the plume are being managed under a North Carolina Registered
Environmental Consultant (REC) Program Remedial Action Plan (RAP). Total VOC iso-
concentration contour maps prepared by others that depict the extent and orientation of the shallow
and deep plume on the Subject Site (as of 2017) are presented in Appendix A.

In July 2019, the John R. McAdams Co. Inc. (McAdams) performed a limited assessment on the
Site that included the advancement of 24 soil borings using direct push technology to a depth of
six feet below land surface (BLS) to allow for the collection and analysis of soil gas and soil in the
footprint of the proposed redevelopment structures (Buildings 1 through 4). A map of the sample
locations and proposed redevelopment is presented in Appendix A. As reported in the Soil Gas
and Soil Sampling Report (McAdams, 2019), findings of the assessment revealed:

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 3 April 3, 2020
• Soil at the Site generally consists of approximately 6 inches of topsoil, overlying silty clay
(0.5 to 2 feet BLS) and clayey silt (2 to 6 feet BLS) of varying color.
• Field screening results did not reveal evidence of impacts in soil.
• No VOCs were detected at concentrations greater than associated North Carolina
Department of Environmental Quality (NCDEQ) Non-Residential Soil Gas Vapor
Intrusion Screening Levels (VISLs) in Building footprints 1 through 4. Compounds with
detectable concentrations were primarily associated with petroleum and solvent-related
compounds and were reported at least one order of magnitude below associated Non-
Residential Soil Gas VISLs.
• NCDEQ Risk Calculator results suggested that an unacceptable vapor intrusion risk was
unlikely to be present for a non-residential worker in proposed Buildings 1 through 4.
• Except for a detection of acetone below the Commercial/Industrial Preliminary Soil
Remediation Goal (PSRG) (which was attributed to a laboratory artifact), no VOCs or
semi-volatile organic compounds (SVOCs) were reported at detectable concentrations
above the reporting limit.
• Total chromium was detected in every soil sample collected. Follow-on hexavalent
chromium analysis revealed hexavalent chromium concentrations below the associated
Commercial/Industrial PSRG, and, suggested that total chromium was predominantly
present in its trivalent state at the Site.
• In addition to total chromium, several other metals were reported at detectable
concentrations below associated Commercial/Industrial PSRGs. Concentrations of metals
reportedly fell within the background metals range for soils in North Carolina (Dragun and
Chekiri, 2005).
• Risk Calculator results suggested that a direct contact soil exposure risk was not present
for non-residential workers, construction workers, or recreators/trespassers at the Site.

As documented in a 15 January 2020 letter prepared by the NCBP, based on the results of soil gas
risk calculations presented in the 2019 assessment, and based on the proposed non-residential reuse
redevelopment, land use restriction referenced in subparagraph 15.h.i in the BFA had been
satisfied and no additional VI assessment or mitigation was necessary for the proposed
redevelopment. As a result, the PD has elected to not construct and install a VIMS for proposed
buildings.

Soil assessment results suggested that it was unlikely for impacted soil to be encountered during
site redevelopment above the water table. Further, unsaturated soil results met the criteria for
potential export to be classified as beneficial fill per Issue 15: Soil Import/Export of the
Brownfields Program Guidelines and Issue Resolutions document (dated December 2017), and

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 4 April 3, 2020
could potentially be used on other sites following NCBP approval. It is our understanding that
NCBP concurred with the findings and conclusions of the 2019 assessment report (McAdams).

Based on these findings, the potential for construction activities to encounter groundwater and
saturated soil was identified as the primary potential exposure pathway of concern for this
redevelopment project.
1.2 Sampling Objectives
The objectives of the investigation were to: 1) further evaluate the potential for construction
activities to encounter impacted groundwater and saturated soil during construction; and 2) support
development of site design and construction strategies to limit and manage potential dewatering
and management of soils excavated below the water table. This information will be used to further
evaluate groundwater as a potential construction exposure pathway.

During proposed redevelopment, known excavation areas that could potentially encounter
groundwater include the following (Figure 2):

• Stormwater sewer system located east and south of Building 4 expected to be as deep as
13 feet below current land surface;
• Stormwater sewer system located south of Building 2 expected to be as deep as 8 feet below
current land surface;
• Stormwater pond located south of Building 2 expected to be as deep as approximately 14
feet below current land surface; and,
• Stormwater pond located north of Building 1 expected to be as deep as approximately 12
feet below current land surface.

Work performed as part of this assessment was conducted in general accordance with NCBP
approved Limited Groundwater and Saturated Soil Assessment Work Plan (Rev 1), dated 21
January 2020 (Geosyntec).
2 FIELD ACTIVITIES AND SAMPLING METHODOLOGY
On 28 and 29 January 2020, Geosyntec oversaw Parratt Wolff, Inc. of Hillsborough, North
Carolina advance four soil borings to the maximum depth of proposed excavation in locations
depicted on Figure 2. Soil samples from the base of each soil borings were collected as
summarized in Table 1. Boreholes were converted to permanent Type II monitoring wells. Well
construction details are summarized in Table 2. Monitoring wells were dry at the time of well
installation and, apart from MMW-2 that reported less than an inch of groundwater throughout the

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 5 April 3, 2020
gauging period, remained dry for the duration of the monitoring well gauging period (between 5
February 2020 and 9 March 2020). As a result, no groundwater samples were collected as part of
this limited assessment. Further details of the assessment are included in Sections 2.3 through 2.8.

Field notes are provided in Appendix B. Soil boring logs and monitoring well construction logs
are provided in Appendix C.
2.1 Health and Safety Planning
Prior to the start of work, Geosyntec updated the Site-specific Health and Safety Plan in general
accordance with the Occupation Safety and Health Administration (OSHA) rules (29 CFR
1910.120).
2.2 Utility Clearing and Locating
To address potential underground utilities, Geosyntec contacted the North Carolina 811 one-call
system a minimum of 72 business hours before beginning the assessment to notify member utilities
of the subsurface work. Because 811 utility locating services only identified utilities up to the
property boundary, Geosyntec contracted with a private subsurface utility exploration (SUE)
surveyor (Taylor Wiseman and Taylor [TWT] out of Apex, North Carolina) to identify utilities in
assessment areas.
2.3 Soil Boring Advancement and Sampling
Monitoring well soil borings (SB-1 through SB-4) (Figure 2) were advanced using a hollow stem
auger (HSA) to the proposed maximum depth of each excavation area as follows:

As summarized above, borings were advanced using HSA drilling to a depth that approximated
the maximum depth of proposed construction activities for the area or to auger refusal (i.e. partially
weathered rock [PWR]).

A split spoon sampler was used to collect soil samples at continuous depth intervals. Soils were
screened continuously (every 1 foot) for evidence of total VOCs using a Photoionization Detector
(PID) (Appendix C). Soils were also geologically classified in general conformance with the
Unified Soil Classification System (USCS) (Appendix C).

Soil samples were collected from the bottom 2-foot interval of each boring. One discrete grab
sample was collected using laboratory supplied grab sample equipment (i.e., Terra Core®). The
discrete grab sample was placed in appropriately labeled laboratory-supplied bottle ware
designated for VOC analysis by United States Environmental Protection Agency (U.S. EPA)
Method 8260B.

Remaining soil from the sampling interval was homogenized in a decontaminated stainless-steel
bowl and placed into laboratory-supplied bottle wares for analysis of the following parameters:

• SVOCs by U.S. EPA Method 8270C; and

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 7 April 3, 2020
• The eight Resource Conservation and Recovery Act (RCRA) metals plus hexavalent
chromium by U.S. EPA Methods 6010B, 7174A, and 7199.

Bottle ware was labeled with the sample location, date and time, and, placed on ice and submitted
to Pace for analysis following chain-of-custody procedures. A total of four soil samples plus one
duplicate sample were submitted for VOC, SVOC, and 8 RCRA metals plus hexavalent chromium
analysis.
2.4 Monitoring Well Installation
Air rotary drilling methods were used to further advance boreholes where refusal was encountered
in PWR (SB-1 and SB-4) in order to reach target well maximum depth of proposed excavation in
each area. The four boreholes were then converted into Type II permanent monitoring wells
(Merritt (M) MW-1 through MMW-4) (Figure 2). Type II monitoring wells were installed into
each borehole in accordance with North Carolina Administrative Code (NCAC) Title 15A
Subchapter 02C (NCAC 2C) (NCDENR, 2009). Monitoring wells were constructed of 2-inch
Schedule 40 polyvinyl chloride (PVC), a 5-foot standard 0.010-inch slotted screen and 2-inch
Schedule 40 PVC riser pipe to surface. Remaining annular space around the monitoring well was
backfilled with filter pack sand in accordance with NCAC 2C (NCDENR, 2009) and extended to
approximately two feet above the top of the well screen consistent with EPA Region 4, Science
and Ecosystem Support Division (SESD), Design and Installation of Monitoring Wells Guidance
(effective date January 29, 2013). A 2-foot well seal, meeting ASTM D-5092 (2010) method
requirements and EPA Region 4, SESD, Design and Installation of Monitoring Wells Guidance
(effective date January 29, 2013), was installed on top of the filter pack. The well was completed
to surface with concrete pad and stick-up monitoring well protective cover.
2.5 Groundwater Sampling and Gauging
Monitoring wells were dry at the time of installation and, apart from MMW-2, remained dry during
the month-long gauging period (between 5 February 2020 and 9 March 2020). Water level
measurements (Table 2) were reported as being between 0.07-inch (on 9 March 2020) and 0.09-
inch (on 5 and 10 February 2020) in MMW-2. Groundwater was not sampled due to the lack or
low volume of water in monitoring wells MMW-1 through MMW-4.
2.6 Monitoring Well Abandonment
Monitoring wells remain on-site, however, will be abandoned in general accordance with
procedures for well abandonment outlined in 15A NCAC 02C .0113, once they are no longer
needed.

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 8 April 3, 2020
2.7 Decontamination
Equipment used between borings was decontaminated using an initial water rinse followed by
cleaning with Alconox® and final rinse of deionized water.
2.8 Monitoring Well Locating
A handheld GPS unit and field measurements was utilized to collect the approximate coordinates
of the monitoring wells.
3 LABORATORY ANALYSIS RESULTS
Soil results (detections only and compounds with RLs above respective PSRGs) are summarized
Table 3. The soil analytical results were compared to the NCDEQ DWM Inactive Hazardous
Sites Branch (IHSB) Residential, Commercial/Industrial and Protection of Groundwater PSRGs
(NCDEQ, 2019a).

Laboratory analytical reports are provided in Appendix C. An electronic data deliverable (EDD)
of laboratory data is also being submitted to the NCBP under separate cover in conjunction with
this report. Level II Quality Assurance (QA)/Quality Control (QC) was reported by Pace in the
analytical report deliverable.
3.1 Soil Analytical Results
3.1.1 VOCs
No VOCs were reported above associated laboratory Reporting Limits (RLs) (Table 3).
3.1.2 SVOCs
No SVOCs were reported above associated laboratory RLs (Table 3).
3.1.3 Metals
The following metals were reported at detectable concentrations above associated RLs (Table 3):

• Arsenic: detected in four samples collected plus the duplicate sample between 1.3 and 3.3
milligrams per kilogram (mg/kg) above the associated Residential and Protection of
Groundwater PSRGs. Arsenic in sample SB-4 (and the associated duplicate sample [SB-
DUP-1]) was also reported above the Commercial/Industrial PSRG. Detected arsenic
concentrations were within the range and below the mean of regional background metals
in soil (Dragun and Chekiri, 2005).

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 9 April 3, 2020
• Barium: detected in four samples collected plus the duplicate sample between 32.6 and 222
mg/kg, below associated Commercial/Industrial, Residential, and Protection of
Groundwater PSRGs.
• Cadmium: detected in one sample at 0.2 mg/kg below associated Commercial/Industrial,
Residential and Protection of Groundwater PSRGs.
• Total Chromium: detected in four samples plus the duplicated between 10.4 and 44.4
mg/kg. Detected total chromium concentrations were within the range and below the mean
of regional background metals in soil (Dragun and Chekiri, 2005).
• Hexavalent Chromium: detected in one sample at 1.14 mg/kg below the
Commercial/Industrial and Protection of Groundwater PSRG, but above the Residential
PSRG. RLs for the remaining samples analyzed for hexavalent chromium were also
reported above the associated Residential PSRG but below the associated
Commercial/Industrial PSRG.
• Lead: detected in four samples plus the duplicate sample between 6 and 12.4 mg/kg below
Commercial/Industrial, Residential and Protection of Groundwater PSRGs. Detected lead
concentrations were within the range and below the mean of regional background metals
in soil (Dragun and Chekiri, 2005).
• Mercury: detected in three of the four samples, plus the duplicate sample between 0.0088
and 0.021 mg/kg below Commercial/Industrial, Residential and Protection of Groundwater
PSRGs.
3.1.4 Soil Risk Calculator Results
The NCDEQ Risk Calculator (December 2019b) was used to evaluate the cumulative risk of
constituents identified in soil analysis recognizing that default PSRGs are conservative in nature.
The Calculator was run using compounds with reportable concentrations above the RL and
compounds with RLs above respective Residential PSRGs. Results, presented in Appendix D,
showed a carcinogenic risk of less than 1.0E-05 and hazard indices less than 1.0 for the non-
residential, construction worker and recreator/trespasser direct contact exposure pathways. An
unacceptable carcinogenic risk and hazard index greater than 1.0E-04 and 1.0, respectively, was
estimated for the residential exposure pathway.
3.2 QA/QC Results
One blind duplicate soil sample (SB-DUP-1 associated with SB-4) was collected and submitted
for laboratory analysis (Table 3). Soil results were within 10 standard deviations for compounds
detected SB-DUP-1 and SB-4 (except for barium).
QA/QC also included the analysis of a trip blank for VOC analysis by US EPA Method 8260D,
and the inclusion of temperature blanks in each soil sample cooler shipped to the laboratory.

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 10 April 3, 2020
4 INVESTIGATION DERIVED WASTE (IDW) MANAGEMENT
Because field observations did not indicate the presence of gross impacts, soil cuttings were spread
on ground surfaces.
5 FINDINGS
Based on the results of this assessment, Geosyntec offers the following findings:

• Monitoring wells installed as part of this assessment were dry at the time of installation
and, except for MMW-2 (with less than or equal to 0.09-inch measurable water), remained
dry during the month-long gauging period (between 5 February 2020 and 9 March 2020).
Groundwater was not sampled as part of this assessment because of the lack or low volume
of groundwater monitoring wells installed.
• No VOCs or SVOCs were detected above applicable soil screening criteria (Residential,
Commercial/Industrial, and/or Protection of Groundwater PSRGs) in soil samples
collected between 5 and 12 feet BLS at the Site.
• No target COCs associated with the Edward Weck plume that underlies the Site were
detected in the soil samples.
• Arsenic concentrations ranging between 1.3 mg/kg to 3.3 mg/kg were detected in the four
samples collected, plus the duplicate sample (of SB-4), at concentration greater that the
Residential (in SB-1 through SB-4, plus the duplicate) and/or Commercial/Industrial (SB-
4 plus the duplicate collected at 10 to 12 feet BLS) PSRGs. With the exception of SB-4
and the duplicate collected at SB-4 (with arsenic concentrations reported at 3.3 mg/kg),
arsenic results from this sampling event were similar to the range of arsenic concentrations
(0.92 to 1.8 mg/kg) reported from the 0 to 6 feet BLS sample interval in a previous soil
assessment performed at the Site (McAdams, 2019). Arsenic concentrations reported were
within the regional range or below the mean for metals in North Carolina soils (Dragun
and Chekiri, 2005) and are likely attributable to naturally occurring conditions in the soil.
• Hexavalent chromium was reported in one of the four soil samples collected (SB-2
collected at 5 to 7 feet BLS) at a concentration above the Residential PSRG, but below the
Commercial/Industrial and Protection of Groundwater PSRG. A similar concentration of
hexavalent chromium (2.2 mg/kg) was detected in soil collected from 0 to 6 feet BLS in
previous assessment performed at the Site (McAdams, 2019). Results suggest that total
chromium is predominantly present in its trivalent state at the Site.
• Soil risk calculator results suggest that a direct contact risk is not present for the intended
use of the Site by non-residential workers, construction workers, and recreators/trespassers.

CAR200036 TW Alexander - IBM Limited Groundwater and Saturated Soil Assessment Report (REV-0) 11 April 3, 2020
6 CONCLUSION AND RECOMMENDATIONS
Based on the findings of this assessment it is unlikely that groundwater will be encountered in the
following proposed deep excavation areas during construction:

• Stormwater sewer system located east and south of Building 4 expected to be as deep as
13 feet below current land surface;
• Stormwater sewer system located south of Building 2 expected to be as deep as 8 feet below
current land surface;
• Stormwater pond located south of Building 2 expected to be as deep as approximately 14
feet below current land surface; and,
• Stormwater pond located north of Building 1 expected to be as deep as approximately 12
feet below current land surface.

Soil test results do not indicate the presence of COCs associated with the underlying Edward Weck
chlorinated solvent plume. This data, combined with data that indicates that groundwater is
unlikely to be encountered during construction, indicates that there is not a complete groundwater
exposure pathway for site construction activities. Soil risk calculator results suggest that non-
residential worker, construction worker, and recreator/trespasser exposure pathways do not appear
to present additional risk for the Site’s intended use and can be reused on the Site during
construction. This information indicates that special handling of soil will not be necessary for
construction workers during site redevelopment for disturbance of soils above partially weathered
bedrock unless construction activities identify the potential presence of groundwater.
