Dear Pat:
1.0 Introduction

Per your request, Hart & Hickman, PC (H&H) has prepared this report to document recent
supplemental groundwater assessment activities conducted at the Charlotte Van & Storage
Brownfields property (Brownfields Project No. 23057-19-060) located at 213 Verbena Street,
and 4607 and 4615 Gilead Street in Charlotte, Mecklenburg County, North Carolina (Site or
subject Site). A Site location map is provided as Figure 1.

In December 2019, H&H completed soil, groundwater, and soil gas assessment activities at the
Site under purview of the North Carlina Department of Environmental Quality (DEQ)
Brownfields Program to evaluate the potential for impact in areas of potential environmental
concern at the Site, and to evaluate risks associated with planned redevelopment. The
Brownfields groundwater assessment activities included installation of five temporary
groundwater monitoring wells (TMW-1 through TMW-5) and collection of samples for
laboratory analysis from each well to evaluate to potential for groundwater impacts at the Site.
Groundwater sample laboratory analytical results identified the chlorinated solvents

tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene, and 1,2-dichloropropane
at concentrations above regulatory screening levels in temporary monitoring well TMW-4
located in the northwestern corner of the Site. The December 2019 temporary monitoring wells
locations are shown in Figure 2.

Per your request, H&H completed supplemental groundwater assessment activities at the Site in
in August 2020 for budgeting purposes to estimate costs associated with potential management
of impacted groundwater during redevelopment activities. Objectives of the supplemental
groundwater assessment activities included:
1. delineation of the extent of chlorinated solvent impacts identified in the northwestern
portion of the Site;
2. evaluation of groundwater conditions in the vicinity of proposed stormwater utility
trenches where excavation activities may intersect the shallow groundwater table;
3. completion of aquifer testing activities; and
4. completion of groundwater inflow models to estimate the volume of groundwater that
may flow into open excavations to assist in management of groundwater (if encountered)
in accordance with the DEQ Brownfields Program approved Environmental Management
Plan (EMP).

A description of the groundwater assessment activities, aquifer testing, groundwater infiltration
estimates, and conclusions are provided in the following sections.

2.0 Groundwater Assessment Activities

The groundwater assessment activities were performed in general accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of
Contaminated Sites (Guidelines) dated January 2020, and most recent versions of the U.S.
Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division
(SESD) Field Branches Quality System and Technical Procedures guidance.

report_charlotte van & storage.doc
Prior to conducting field activities, H&H contacted NC One-Call, the public utility locator, to
mark subsurface utilities at the Site. Additionally, H&H directed the drilling contractor to hand
clear each boring to a depth of approximately 5 feet (ft) below ground surface (bgs) to further
screen the boring locations for the presence of subsurface utilities. In accordance with
Mecklenburg County rules, H&H conducted the groundwater assessment under the existing
Mecklenburg County Subsurface Investigation Permit (SIP No.70002705).

2.1 Temporary Monitoring Well Installation

On August 5, 2020, H&H contracted with Innovative Environmental Technologies, Inc. (IET) to
install four (4) temporary groundwater monitoring wells (TMW-6 through TMW-9) in the
vicinity of the proposed stormwater utility trenches to evaluate the potential for impacted
groundwater that may need to be managed during planned redevelopment activities at the Site.
The August 2020 temporary groundwater monitoring well locations are depicted on Figure 2.

IET advanced the temporary groundwater monitoring well borings utilizing decontaminated
stainless steel hand augers and a track-mounted direct push technology (DPT) drill rig capable of
utilizing hollow stem auger drilling techniques. Continuous soil samples were collected from the
center of the hand auger bucket or from auger cuttings at each temporary well location. The soil
samples were logged for lithological description and inspected for indication of potential impacts
by observation for staining and for the presence of volatile organic vapors using a calibrated
photoionization detector (PID). Results of field screening did not identify obvious evidence of
impacts in the temporary well borings.

Each temporary well soil boring was advanced until adequate groundwater was encountered.
Temporary groundwater monitoring well TMW-6 was installed to 17 ft bgs, TMW-7 was
installed to 11 ft bgs, TMW-8 was installed to 10 ft bgs, and TMW-9 was installed to 12 ft bgs.
The temporary monitoring wells were constructed of 2-inch diameter PVC well casing with 8 to
10 ft of well screen set to bracket the water table. A sand filter pack was placed from the bottom
of the borings to approximately 1 to 2 ft above the top of the wells screen, and a hydrated

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
bentonite seal was placed from the top of the sand filter pack to the ground surface. Boring logs
with well construction diagrams and field screening results are provided in Appendix A.

2.2 Groundwater Elevations

The elevation of the top of well casing for each temporary well was surveyed by H&H relative to
mean sea level (MSL) using a previously surveyed on-Site benchmark. Upon installation, the
temporary monitoring wells were allowed to equilibrate to static conditions for at least 24 hours
and a decontaminated electronic water level indicator was used to measure the depth to the water
table relative to the tops of the well casings. Using the depth to water and tops of casing survey
measurements, H&H calculated groundwater elevations above MSL at each well location.

Temporary monitoring well construction details, depth to water measurements, and groundwater
elevations are summarized in Table 1. As indicated in Table 1, groundwater elevations measured
on August 7, 2020 ranged from 699.72 ft above MSL in TMW-6 to 709.82 ft above MSL in
TMW-9. Groundwater elevations will fluctuate seasonally and with the amount of rainfall, but
are typically higher during the late winter and early spring months.

2.3 Groundwater Sampling

Upon collection of depth to groundwater measurements, the temporary wells were developed by
removing water from the screened portion of the temporary well until field parameters had
stabilized (pH ± 0.1 SU and conductivity varied no more than 5%) or until dry. Following
development, the wells were purged using low flow/low stress sampling techniques utilizing a
peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing was
placed in the approximate mid-portion of the well screen and groundwater was removed at a rate
no more than 200 milliliters per minute. Water quality meters were used to collect
measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and
specific conductivity at 5-minute intervals during the purging process. Purging was considered

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
complete when field parameters stabilized (pH ± 0.1 SU and conductivity varied no more than
5%). Well development and groundwater sampling forms are provided in Appendix B.

Following well development, groundwater samples were collected directly into laboratory
supplied sample containers using the “soda straw” method to minimize potential volatile loss
through the peristaltic pump head. The sample containers were then labeled with the sample
identification, date, and requested analysis, placed in a laboratory supplied cooler with ice, and
delivered to Pace Analytical Services (Pace) under chain-of-custody protocol for analysis of
volatile organic compounds (VOCs) by EPA Method 8260. The chain-of-custody record and
laboratory analytical report is provided in Appendix C.

Following sample collection, the monitoring wells were properly abandoned by IET personnel
and the well locations were recorded using a hand-held GPS unit. Driller provided well
construction forms and well abandonment records are included in Appendix A.

2.4 Groundwater Analytical Results

The laboratory analytical results were compared to the DEQ 15A North Carolina Administrative
Code (NCAC) 2L Groundwater Quality Standards (2L Standards), DEQ NCAC 2B Surface
Water Standards (2B Standards), and the DEQ Division of Waste Management (DWM) Vapor
Intrusion Residential and Non-Residential Groundwater Screening Levels (GWSLs). Laboratory
analytical results are summarized in Table 2.

Laboratory analytical results indicate that PCE (up to 9.4 micrograms per liter [µg/L]) was
detected at concentrations that exceed the 2L Standard and 2B Standard of 0.7 µg/L in temporary
monitoring wells TMW-6 and TMW-7, which were installed near proposed stormwater utility
lines located in the western and northern portions of the Site, respectively. In addition, TCE was
detected at a concentration of 101 µg/L in the groundwater sample collected from TMW-7,
which exceeds the 2L Standard of 3 µg/L and the 2B Standard of 30 µg/L. TCE was also
detected at a concentration that exceeds the 2L Standard, but is below the 2B Standard in well

TMW-6 (4.7 µg/L). No other compounds were detected at concentrations above the DEQ
regulatory screening criteria in the TMW-6 and TMW-7 groundwater samples. No compounds
were detected at concentrations above the laboratory method detection limits in groundwater
samples collected from temporary monitoring wells TMW-8 and TMW-9 which were installed
near the northeast and southeast corners of the current Site building, respectively. PCE and TCE
concentrations for each well locations are provided on Figure 2.

Results of groundwater assessment activities completed at the Site indicate that chlorinated
solvent impacts in Site groundwater are limited to the northern and northwestern portions of the
Site. Based on hydraulic gradient, impacts identified in the northern and northwestern portions
of the Site appear to be attributable to nearby off-Site source(s) located to the north-northeast.

3.0 Aquifer Testing and Groundwater Infiltration Estimate

To estimate the groundwater infiltration rate into open excavations, H&H performed the
following tasks:
1) slug tests were completed at each temporary well to estimate the mean aquifer hydraulic
conductivity at the Site;
2) the mean aquifer hydraulic conductivity and other measured and published aquifer
parameters were used to calculate horizontal and vertical groundwater velocities; and
3) daily volumetric water inflow rates were estimated using the calculated groundwater
velocities and planned utility trench excavation dimensions.

Each of these steps is discussed further below.

3.1 Aquifer Testing

H&H performed slug tests at each temporary groundwater monitoring well to characterize
hydraulic properties of the shallow aquifer and to estimate aquifer hydraulic conductivity.
Hydraulic conductivity is a measure of an aquifer’s ability to transmit water. The slug test
Mr. Pat Foster

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
consisted of removing a volume of water from each well using a 48-inch disposable bailer.
Water level recovery in the wells was then monitored over time using a pressure transducer and
data logger. The slug tests were analyzed with AQTESOLV software utilizing the method of
Bouwer and Rice to estimate aquifer hydraulic conductivity, which can in turn be used to
estimate groundwater flow velocity.

The calculated horizontal hydraulic conductivities are presented in the table below:

Well ID Hydraulic Conductivity
(ft/day)
TMW-6 0.087
TMW-7 0.200
TMW-8 0.031
TMW-9 0.137

The geometric mean hydraulic conductivity for shallow groundwater aquifer is approximately
0.093 ft/day. The AQTESOLV generated slug test data plots are included in Appendix D.

3.2 Groundwater Velocity

Horizontal Groundwater Flow Velocity
H&H calculated the average linear horizontal flow velocity utilizing the following equation:

Vx = Kx x dHx
ne dLx

Where:

Vx = average horizontal groundwater velocity;

Kx = horizontal hydraulic conductivity (0.093 ft/day, conservatively used the geometric
mean value);

ne = aquifer effective porosity (assumed to be 0.35 based on literature values); and

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
dHx = horizontal hydraulic gradient (estimated based on data from the temporary wells)
dLx

Based on the above, the average horizontal groundwater velocity at the Site is estimated to be
0.0050 ft/day.

Vertical Groundwater Flow Velocity
To estimate the volume of water which may flow into the saturated base of an open excavation,
H&H calculated the average vertical groundwater flow velocity utilizing the following equation:

Vy = Ky x dHy
ne dLy

Where:
Vy = average linear vertical groundwater velocity;

Ky = vertical hydraulic conductivity (0.093 ft/day, conservatively assumed to be the same
as horizontal hydraulic conductivity);

ne = aquifer effective porosity (assumed to be 0.35 based on literature values); and

dHy = vertical hydraulic gradient (assumed to be 10% of horizontal gradient
dLy based on typical values)

Based upon the above, the average vertical groundwater velocity is estimated to be
0.00050 ft/day.

3.2 Groundwater Infiltration Estimate

During a conference call held on September 2, 2020, H&H and LMC personnel reviewed
approximate dimensions and depths of planned stormwater utility excavations relative to
groundwater elevations measured at the Site. Based on comparison of groundwater elevations
and the depths to the base of each utility excavation area, it was determined that the planned base
of the utility excavations may intersect the groundwater table during utility installations.

Page 9

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
LMC personnel provided H&H a copy of the most recent Site plans prepared by BGE dated July
9, 2020, which included approximate dimensions (including depths) of the stormwater utility
excavation areas. For construction purposes, the proposed stormwater utility excavations were
divided into six sections based on stormwater pipe diameter and proposed groundwater
management scenario (Section A through Section F). Proposed groundwater management areas
are shown in Figure 3.

Groundwater management areas Section A through Section C are located in the northern and
western portions of the Site in areas of chlorinated solvent impacted groundwater. Should
groundwater be dewatered from utility trenches in these management areas, it will need to be
managed in accordance with the DEQ Brownfields Program approved EMP (e.g., containerized
and disposed off-Site). No compounds are present at concentrations above the DEQ 2B Surface
Water Standards in groundwater management areas Section D through Section F located in the
eastern and southeastern portions of the Site. Should groundwater in utility trenches need to be
dewatered from these management areas, the water can be tested to confirm there are no impacts
and discharged to the erosion control and stormwater retention systems in accordance with
applicable best management practices.

For groundwater inflow modeling purposes, H&H calculated groundwater infiltration rates based
on 10 linear ft sections of open utility trench excavations. H&H then used the dimensions of the
excavation areas provided by LMC (including the 10 linear ft section), an estimate of saturated
thickness of the excavation sidewalls (based on groundwater elevations measured during the
December 2019 and August 2020 groundwater sampling events), and the estimated horizontal
groundwater velocities. For the vertical volume estimate, H&H used the estimated maximum
utility line excavation footprint area (ft2) and the estimated vertical groundwater velocity. The
total groundwater volume estimate for each section is reported in gallons per day per 10 linear ft
of open utility trench excavation.

Results of the model indicate that dependent on the diameter of the proposed stormwater piping,
a range from approximately 4 gallons to approximately 14 gallons of impacted groundwater per

day may need to be managed for every 10 linear ft of open excavation in Section A through
Section C. Detailed groundwater inflow model results for each groundwater management area
are provided below:

Impacted Groundwater Management Areas
Section A – 30” Pipe
 approximately 12 gallons per day per 10 linear ft of open excavation

Section B – 30” pipe
 approximately 4 gallons per day per 10 linear ft of open excavation

Section C – 60” Pipe
 approximately 14 gallons per day per 10 linear ft of open excavation

Non-Impacted Groundwater Management Areas
Section D – 60” pipe
 approximately 19 gallons of non-impacted groundwater per day per 10 linear ft of open
excavation

Section E – 24” pipe
 approximately 7 gallons of non-impacted groundwater per day per 10 linear ft of open
excavation

Section F
 15” pipe: approximately 10 gallons per day per 10 linear ft of open excavation
 18” pipe: approximately 9 gallons per day per 10 linear ft of open excavation
 24” pipe: approximately 15 gallons per day per 10 linear ft of open excavation

To account for season variability, fluctuation of the groundwater table, and potential increased
hydraulic gradient near the utility trenches, a conservative estimated range of 5 to 10 gallons per
day per 10 linear ft of open excavation should be added to each estimate described above.

4.0 Summary and Conclusions

H&H completed supplemental groundwater assessment activities at the Charlotte Van & Storage
Brownfields property to evaluate groundwater quality and estimate the volume of groundwater
that may need to be managed in the areas of planned utility installations. A summary of the
results of recent groundwater assessment activities is provided below.

 Laboratory analytical results indicate that chlorinated solvents (PCE and/or TCE) were
detected at concentrations exceeding both the DEQ 2B Surface Water Standards and the
DEQ 2L Groundwater Standards in groundwater samples collected in the western and
northern portions of the Site (TWM-6 and TMW-7; Figure 2). Based on results of the
previous December 2019 and recent August 2020 groundwater assessment activities, the
source(s) of impacts identified in the northern and northwestern portions of the Site
appears to be located off-Site to the north and/or north-northeast.

 Based results of the groundwater assessment activities and the current redevelopment
plan, the depth of proposed utility trench excavations in the northern and western portions
of the Site may intersect the groundwater table (Section A through Section C). If
groundwater is encountered in these areas during redevelopment activities and
dewatering is needed for work to continue, groundwater generated during dewatering will
need to be managed in accordance with the DEQ Brownfields approved EMP.

 Using data obtained during aquifer testing activities and dimensions of the proposed
utility trench excavations in the northern and western portions of the Site, H&H estimates
that a range of approximately 4 to 14-gallons of groundwater per day may need to be
managed in each 10 linear ft section of open excavation. A conservative estimated range
Mr. Pat Foster
December 11, 2020

s:\aaa-master projects\lennar (len)\len-008 verbena assemblage\supplemental groundwater assessment\final to deq\23057 - supplemental groundwater assessment
report_charlotte van & storage.doc
of 5 to 10 gallons per day per 10 linear ft of open excavation should be added to this
estimate to account for season variability, fluctuation of the groundwater table, and
potential increased hydraulic gradient near the utility trenches.

 Laboratory analytical results did not indicate groundwater impacts in the vicinity of the
eastern and southeastern proposed utility trenches (Section D through Section F).

H&H understands that dewatering points or sumps will be installed in the vicinity of the utility
trench excavations to minimize groundwater inflow and keep the work area dry for construction
of utilities. In accordance with the DEQ-approved EMP, groundwater generated during
redevelopment activities in the northern, western, or southwestern portions of the Site will need
to be containerized and disposed off-Site. Alternatively, a groundwater treatment system can be
installed at the Site and the treated groundwater can be discharged to the stormwater control
systems under a temporary National Pollutant Discharge Elimination System (NPDES) permit.

Groundwater generated during dewatering activities in the eastern and southeastern portions of
the Site can be discharged to the stormwater control systems using applicable best management
practices unless on-Site personnel observe obvious indication of contamination during
dewatering such as odors or sheen on the water. In the unlikely event this occurs, H&H should
be contacted to observe the suspect conditions.
