Dear David:
1.0 Introduction
On behalf of the Charlotte Area Transit System (CATS), Hart & Hickman, PC (H&H) has
completed soil and groundwater sampling activities at the Norfolk Southern Intermodal Facility
(NSIF) Brownfields property located at North Brevard Street and Parkwood Avenue in
Charlotte, Mecklenburg County, North Carolina. A site location map is included as Figure 1.
The assessment activities were completed in accordance with the Brownfields Environmental
Management Plan Revision 3 dated January 23, 2013 (EMP) and the EMP Addendum dated
September 25, 2015. Only data that are related to the proposed CATS maintenance building are
being provided with this document. Preliminary designs for the maintenance building are
provided on Figure 2. The data provided in this report were collected to evaluate impacted soil
and groundwater management activities during and following construction of the maintenance
building. In addition, these data are being provided for the purpose of complying with Land Use
Restriction Number 6 of the Notice of Brownfields Property, which requires the evaluation of the
potential for vapor intrusion for future site buildings which will be occupied.

2.0 Methodology
2.1 Soil Sampling Activities
A total of eight soil borings were installed in the vicinity of the proposed maintenance facility
(Figure 2) between August 13, 2014 and October 2, 2014. Prior to advancing the soil borings,
North Carolina 811 was contacted to locate public utilities. Additionally, H&H contracted with
a private utility locator to identify the locations of potential subsurface utilities in the vicinity of
the soil boring locations.
H&H contracted with Probe Technologies, Inc (Probe) to advance the soil borings using a direct-
push technology (DPT) drill rig. Prior to advancing each boring using the DPT, H&H directed
Probe to clear the first 5 ft of each soil boring using a decontaminated stainless steel hand auger
to reduce the potential for subsurface utility damage. Soils below a depth of 5 ft were retrieved
from each boring using a DPT macro-core sampler equipped with dedicated 5 ft acetate macro-
core liners. During boring advancement, recovered soil cores were described for lithologic
purposes, observed for the presence of staining and odors, and field-screened for the presence of
organic vapors with a calibrated photo-ionization detector (PID). Boring logs with lithologic
descriptions and field screening results are included in Appendix A.
Based on the depth with the highest field screening readings, one sample was collected from
each boring for laboratory analysis. Generally, the proposed construction cut depths for the
NSIF property were less than five ft below ground surface (bgs). Therefore, if no significant
impacts were identified by field screening, a sample was collected from a 2-foot interval between
0 and 5 ft bgs.
The soil samples were collected in laboratory-supplied containers, properly labeled, and placed
in an iced cooler. Samples were delivered to Prism Laboratories, Inc. (Prism) in Charlotte,

North Carolina under standard chain-of-custody protocol. The soil samples were analyzed for
one or more of the following as defined in the EMP or EMP Addendum.
Extractable Petroleum Hydrocarbons (EPH) by the Massachusetts Department of
Environmental Protection (MADEP) Method
1,4-dioxane by US Environmental Protection Agency (EPA) Method 8260 SIM
Total petroleum hydrocarbon diesel range organics (TPH DRO) by EPA Method 8015C
Polychlorinated biphenyls (PCBs) by EPA Method 8082A
Volatile Organic Compounds (VOCs) by EPA Method 8260B
Semi-Volatile Organic Compounds (SVOCs) by EPA Method 8270C
Hazardous Substance List (HSL) Metals plus barium by EPA Method 6010A/7471A
Hexavalent chromium by EPA Method 7196A
Toxicity Characteristic Leaching Procedure (TCLP) chromium by EPA Method 6010C
Select soil borings (DPT-1, DPT-15, DPT-49, and DPT-50) were converted to temporary
monitoring wells TMW-5, TMW-6, TMW-12, and TMW-13, respectively. If not converted to a
temporary monitoring well, the borings were abandoned with bentonite chips. Because there
was no field evidence of significant impacts and based on the small amounts generated,
investigation derived waste (IDW) soil generated during boring advancement and sampling
activities were spread on the nearby ground surface.

2.2 Groundwater Sampling Activities
A total of four soil borings were advanced into the water table and temporary monitoring wells
were installed (Figure 2). Each temporary monitoring well was constructed to bracket the water
table with a 1-inch or 2-inch diameter, 0.01-inch slotted well screen and completed with 2-inch
diameter PVC riser pipe. A filter sand pack was installed from the bottom of each of the well
boring to approximately 2 ft above the well screen, and a bentonite seal was installed above the
filter sand pack.
Prior to sampling, the static depth-to-water at each temporary monitoring well was gauged using
an electronic water level meter (Table 2). Water levels in the area of the maintenance trench are
only 1 to 2 ft below grade. Each temporary monitoring well was developed and purged by low-
flow methods using a peristaltic pump and new dedicated polyethylene tubing. Low-flow
purging was conducted until pH, temperature, conductivity, and turbidity stabilized. After
purging, the groundwater samples were collected into laboratory supplied bottles, properly
labeled, and placed in a cooler with ice. Samples were subsequently delivered to Prism
Laboratories, Inc. (Prism) in Charlotte, North Carolina under standard chain-of-custody protocol.
Groundwater samples were analyzed for one or more of the following:
VOCs by EPA Method 8260B
SVOCs by EPA Method 8270C
PCBs by EPA Method 8082
HSL Metals by EPA Method 6020A/7471A
Hexavalent Chromium (SM 3500)
After sampling was completed, the temporary monitoring well materials were removed, and the
borings were abandoned with cement grout. Because there was no field evidence of significant

impacts and based on the small amounts generated, IDW groundwater generated during boring
advancement and sampling activities was spread on the nearby ground surface. Well
abandonment records are provided in Appendix C.
3.0 Analytical Laboratory Results
The analytical results of the soil samples are summarized in Table 1. The analytical results of the
groundwater samples are summarized in Table 3. Laboratory analytical data reports and chain-
of-custody records are included as Appendix B.
3.1 Soil Analytical Results
In general, soil analytical results were compared to DENR Inactive Hazardous Site Branch
(IHSB) Preliminary Industrial Health-Based Soil Remediation Goals (PSRGs). Metal results
were also compared to two times the average regional background metal concentrations (2x
background) as specified in the EMP Addendum. TPH DRO results were compared to the
DENR UST Action Levels.
EPH Analytical Results
The only sample analyzed for EPH was DPT-1 (0-2) and the concentration was below the
laboratory reporting limit.
TPH DRO Analytical Results
Soil samples DPT-24 (4-6) and DPT-26 (1-3) both had concentrations of TPH DRO above the
DENR UST Action Level of 10 mg/kg with concentrations of 2,700 mg/kg and 92 mg/kg,
respectively.
PCB Analytical Results
Mr. David Wolfe, PE
February 20, 2015
Page 6
S:\AAA-Master Projects\Charlotte Area Transit System (CAT)\CAT-003 BLE\NSIF Assessment\New Building Plans\Report\Maintenance Building Report.doc
Soil samples DPT-1 (0-2) and DPT-15 (3-4) were analyzed for PCBs. No PCBs were detected
above the laboratory reporting limits.
VOC Analytical Results
All eight soil samples were analyzed for VOCs. In the sample DPT-24 (4-6) only sec-
butylbenzene was identified above the laboratory reporting limit. The concentrations did not
exceed screening criteria.
SVOC Analytical Results
All eight soil samples were analyzed for SVOCs. Phenanthrene was identified in DPT-24 (4-6)
and fluoranthene and pyrene were identified in DPT-49 (0-2) above the laboratory reporting
limits. The detected SVOC concentrations did not exceed screening criteria.
Metal Analytical Results
Results for antimony, barium, beryllium, cadmium, mercury, thallium, selenium, and hexavalent
chromium were either below their respective laboratory reporting limit, below 2x background
mean, or below screening criteria (Table 1).
Arsenic was only detected in DPT-26 (1-3) at a concentration of 3.9 mg/kg, which slightly
exceeded the Industrial PSRGs.
Although detected in each of the eight soil samples, total chromium concentrations were greater
than 2x background mean in only two of the soil samples. Total chromium was detected in
DPT-26 (1-3) at a concentration of 190 mg/kg and in DPT-1 (0-2) at a concentration of 250
mg/kg. Both of these concentrations are below the Industrial PSRGs. TCLP chromium was
added to soil samples from DPT-1, DPT-26, and DPT 49 to assist in waste profiling with the

landfill. No TCLP chromium was detected in these samples, indicating a low potential for
leaching.
Copper concentrations were greater than 2x background mean in four of the eight soil samples.
These concentrations ranged from 70 mg/kg at DPT-25 (1-3) and DPT-49 (0-2) to 87 mg/kg in
DPT-15 (3-4). These concentrations are below the Industrial PSRGs.
The lead concentration was greater than 2x background mean in DPT-49 (0-2) with a
concentration of 53 mg/kg. Lead concentrations are below PSRGs.
Manganese concentrations were less than 2x background mean and below the Industrial PSRGs.
Nickel concentrations were greater than 2x background in four of the soil samples. These
concentrations ranged from 49 mg/kg in DPT-49 (0-2) to 110 mg/kg in DPT-1 (0-2) and DPT-15
(3-4). Nickel concentrations are below the Industrial PSRGs.
Zinc concentrations were greater than 2x background in only one of the soil samples, with a
concentration of 120 mg/kg in DPT-15 (3-4). Zinc concentrations are below the Industrial
PSRGs.
Soil Management
Based on the results above, soil boring locations were classified as either “Impacted” or “Not
Impacted” (Table 1). Impacted borings were defined based on any detected presence of
contaminants, including metals at concentrations which exceeded 2x background mean. These
indicators are provided on Table 1, and were incorporated into a site-wide Soil Management
Plan figure which outlined areas of the site were to be managed as impacted for the full NSIF
property. The area to be managed as impacted soil in the vicinity of the proposed maintenance
building based on this approved Soil Management Plan figure is included on Figure 2. In non-
Mr. David Wolfe, PE

impacted areas, with appropriate environmental oversight and field screening, soil can be moved
off-site and utilized by the contractor anywhere along the BLE project. This strategy, including
the Soil Management Plan figure and proposed soil management activities, were approved by
DENR in email correspondence dated October 16, 2014. As shown on Figure 2, most of the soil
in the vicinity of the maintenance building should be managed as impacted.
3.2 Groundwater Analytical Results
Groundwater analytical results are summarized on Table 3. The results were compared to the
North Carolina Title 15 Subchapter 2L Groundwater Quality Standards (2L Standard) and the
NCAC 02B Surface Water Quality Standards or National Criteria per EPA (2B Standards).
The VOCs chloroform, tetrachloroethene (PCE), and trichloroethene (TCE) were detected in
groundwater samples from TMW-5, TMW-12, and TMW-13. PCE concentrations exceeded the
2L Standard of 0.7 µg/L in these temporary monitoring wells, ranging from 0.71 µg/L (TMW-5)
to 9.0 µg/L (TMW-13). The concentration of PCE in TMW-13 also exceeded the 2B Standards.
TCE concentrations exceeded the 2L Standard of 3.0 µg/L only in TMW-13. Chloroform was
detected in TMW-5 at a low concentration below the 2L Standard of 70 µg/L.
In addition, manganese exceeded the 2L Standard of 50 μg/L in TMW-12, with a concentration
of 85 μg/L. No other groundwater impacts were detected.

3.3 Groundwater Vapor Intrusion Potential
VOC analytical results for groundwater were also compared to DENR Division of Waste
Management Non-Residential Vapor Intrusion Groundwater Screening Levels (GWSLs) to
determine if vapor intrusion is a potential risk for future site structures. VOC detections in
groundwater were below their respective GWSLs for vapor intrusion.
4.0 Summary and Recommendations
H&H completed soil, groundwater, and vapor intrusion assessment activities in August and
September/October 2014 at the NSIF proposed maintenance building as part of the earlier soil
assessment activities conducted at those times. A total of eight soil borings and four temporary
monitoring wells were installed in proximity to the proposed maintenance building.
Soil Results and Management
Soils in the vicinity of the proposed maintenance building contained detectable levels of DRO,
select VOCs, SVOCs, and metals. Based on these results, soil boring locations were classified
as either “Impacted” or “Not Impacted”. Impacted borings were defined based on any detected
presence of contaminants, including metals at concentrations which exceeded 2x background
mean. These indicators are provided on Table 1, and were incorporated into a site-wide Soil
Management Plan figure which outlined areas of the site were to be managed as impacted for the
full NSIF property. In non-impacted areas, with appropriate environmental oversight and field
screening, soil can be moved off-site and utilized by the contractor anywhere along the BLE
project. This strategy, including the Soil Management Plan figure and proposed soil
management activities were approved by DENR in email correspondence dated October 16,
2014. Most of the soil in the vicinity of the maintenance building should be managed as
impacted.

February 20, 2015

S:\AAA-Master Projects\Charlotte Area Transit System (CAT)\CAT-003 BLE\NSIF Assessment\New Building Plans\Report\Maintenance Building Report.doc
Groundwater Results and Management
PCE, TCE, and manganese were found at concentrations above the 2L Standard in groundwater
at the NSIF proposed maintenance facility. If groundwater is encountered during construction
activities, it should be managed in accordance to the DENR approved EMP, which includes use
of impacted water for dust control in impacted areas of the Brownfields property. Alternatively,
if more substantial dewatering is needed during construction, a secondary outfall could be
obtained and the water treated under the City’s existing temporary construction National
Pollutant Discharge Elimination System (NPDES) permit.
H&H understands permanent dewatering will likely be needed for the maintenance trench. If
this is the case, a permanent (non-construction) NPDES permit will likely need to be obtained
based on the groundwater contaminants.
Vapor Intrusion Evaluation
Based on the low concentrations of VOCs detected in groundwater samples near the maintenance
building; H&H does not recommend further vapor intrusion evaluation or mitigation measures
be implemented. However, to comply with the Notice of Brownfields Property, H&H
recommends submittal of this document to DENR with a request for a written response that the
City has complied with Land Use Restriction 6 related to the proposed maintenance building.
