BACKGROUND 
The Property consists of an approximate 1.9 acre parcel located at 510 West Tremont Avenue in 
Charlotte, North Carolina and identified as Mecklenburg County Parcel No. 119‐164‐21.  F&R 
understands that the Property is currently undeveloped.  The Property was historically a salvage 
yard  and  quarry,  and  prior  investigations  by  others  identified soil  and  groundwater 
contamination consisting of metals and petroleum compounds at the Property.  Based on these 
findings, the Property was submitted to the NCDEQ Brownfields Program.   
Based on the historical site use and sampling data, preparation of a work plan for additional 
sampling of soil, groundwater and soil‐gas was requested Mr. Cody  Cannon of  the NCDEQ 
Brownfields Program in June 2019.  Based on the presence of historic trash fill, the NCDEQ also 
identified  concern  from  methane  gas  intrusion.  The  purpose  of  the  assessment  was  to 
characterize surface soils related to historical site use, determine if there is a risk of methane gas 
or vapor intrusion, and to assist in making risk management decisions for inclusion in the 
Brownfields Agreement.  The following report details the additional assessment conducted in 
accordance  with  the  previously  approved  Work  Plan.  Please  reference  Figure  2  for  sample 
locations. 
CONFIRMATORY SOIL ANALYSIS 
F&R advanced four (4) soil borings at the locations requested by NCDEQ (B‐1, B‐5, B‐6 and B‐9). 
The soil borings were installed in order to collect soil samples for the analysis of RCRA metals and 
hexavalent chromium, volatile organic compounds (VOCs), and semi‐volatile organic compounds 
(SVOCs). In addition, one background sample (B‐10) was collected at the northeast corner of the 
Property  (for  RCRA  metals  and  hexavalent  chromium  only).  During  previous  investigations, 
metals (including Chromium) were detected above the Residential Preliminary Soil Remediation 
Goal (PSRG).  The previous analysis did not differentiate between  hexavalent  and  trivalent 
chromium. The chromium detected was believed to be naturally occurring trivalent chromium; 
however sampling for hexavalent chromium was conducted during this investigation to determine 
the species and concentrations of chromium present.  

Sampling was conducted utilizing direct push technology (Geoprobe™).  Direct‐push technology is 
a truck or track‐mounted tool that pushes sampling devices into the sub‐surface using hydraulic 
pressure.    This  method  creates  little  disturbance,  leaving  only  a  2‐inch  diameter  borehole.  
Additionally, one duplicate sample was collected from soil sample location B‐2 for a total of 6 soil 
samples.  The soil samples were collected from the 0‐2 foot interval below ground surface (bgs) 
at the approximate locations of historic samples SB‐1, SB‐3, the location of the historical quarry, 
and one within the proposed footprint of the proposed multi‐family structure, as requested by

the NCDEQ and shown on the attached Sample Location Plan (Appendix A – Figure 2).  Soil 
samples  collected  were  screened  in  the  field with  a  photoionization  detector (PID)  for  the 
presence of volatile organic compounds (VOCs) by head space analysis.  PID readings above 
background were not identified. 
According to the laboratory results of the soil samples submitted for analysis, VOCs were not 
detected above laboratory method detection limits, except for acetone, a common laboratory 
contaminant.  Acetone concentrations were below its Residential PSRG.  Several SVOCs, including 
benzo(a)anthracene,  benzo(a)pyrene,  benzo(b)fluouranthene,  dibenzo(a,h)anthracene,  and 
indeno(1,2,3‐cd)pyrene  were  detected  above  their  respective  Residential PSRGs.  The 
concentrations detected did not exceed the non‐residential PSRGs.  
Arsenic was detected at concentrations ranging from 2.6 to 20 mg/kg, which exceeds the Residential 
and  Commercial  PSRGs  of  0.68  and  3.0  mg/kg.    The  concentrations  detected  were  generally 
consistent with the concentrations in the background sample (B‐10, 4.5 mg/kg), indicating these 
detections are naturally occurring except in sample SB‐1 (from boring B‐1) which was approximately 
an order of magnitude greater than the background sample.  Hexavalent chromium was detected 
above the Residential PSRG of 0.31 mg/kg, at concentrations of 0.81 mg/kg (in B‐6) and 0.5 and 1.2 
mg/kg  (in  B‐9  and  the  duplicate  from  B‐9).    The  concentrations detected  did  not  exceed  the 
Commercial PSRG of 6.5 mg/kg.  Hexavalent chromium was also detected in the background sample 
at an estimated concentration (‘J’ flag) of 0.29 mg/kg.  The analytical parameters and results are 
summarized on Tables 1 and 2 in Appendix B, and shown on Figure 3.  The laboratory report is 
included in Appendix C.  The borings were backfilled and abandoned with the soil cuttings upon 
completion. 
MONITORING WELL INSTALLATION AND GROUNDWATER SAMPLING 
Groundwater was previously measured by Mill Creek Environmental in monitoring wells during the 
previous groundwater sampling event in February 2017.  The approximate well depths and depths 
to groundwater recorded at that time are as shown on the following table:

Previously installed monitoring wells MW‐1, MW‐2, and MW‐3, could not be located and are 
presumed destroyed.  Therefore, replacement monitoring wells (MW‐1R, MW‐2R, and MW‐3R) 
were installed in the approximate locations of the previous wells using hollow‐stem auger drilling 
techniques.  Soils were screened with a PID during drilling.  The wells were installed by a North 
Carolina Licensed Well Driller from South Atlantic Environmental Drilling and Construction Company 
(SAEDACCO) on July 5, 2019 in accordance with NCAC 2C Well Construction Rules. The wells were 
constructed with 2‐inch PVC and 10 feet of screen.  Gravel pack was installed around the screen 
to  2’  above  the  top  of  the  screen,  with  a  bentonite  seal  installed  above  the  gravel  pack.    A 
cement/bentonite slurry was be placed above the bentonite seal to the ground surface, and the 
wells were finished with an approximate 2 foot stick‐up and locking cap.  The wells were developed 
and the stick‐ups finished on July 11, 2019.  The wells were allowed to stabilize for at least 24‐
hours after development prior to sampling. F&R measured groundwater levels and conducted a 
relative survey of the wells.  The well information is shown on the table below, and a groundwater 
flow map is included as Figure 4. Groundwater flow was measured to be generally to the north‐
northeast.

The well records are included in Appendix D.  MW‐1R is identified as MW‐4R in the well record 
prepared by the driller form SAEDACCO.  PID readings above background were not identified 
during monitoring well installation or sampling. 
F&R sampled the monitoring wells on July 18, 2019.  F&R utilized low flow sampling techniques 
with a submersible pump and dedicated sampling tubing to attempt to minimize turbidity, with a 
turbidity goal of <10 NTU, since sampling for RCRA metals was included in the groundwater 
analysis.    Field measurements were recorded including pH, temperature, and conductivity for 
stabilization prior to collecting samples in accordance with the workplan.  The groundwater samples 
were placed into laboratory provided sample jars for laboratory analysis of VOCs, SVOCs, RCRA 
metals, and hexavalent chromium.  Well MW‐3R was still slightly turbid and the turbidity was 10

The groundwater sample collected from MW‐1R detected target compounds (VOCs, SVOCs, and 
RCRA metals) above laboratory reporting limits and the North Carolina 2L Groundwater Quality 
Standards (NC2LGWQS).  The groundwater sample collected from MW‐2R and MW‐3R and the 
duplicate from MW‐2R detected target compounds (VOCs and RCRA metals) above laboratory 
reporting limits and the NC2LGWQS.  Results of the sample from MW‐2R were generally consistent 
with the duplicate.  The higher turbidity in the sample from MW‐3R may have slightly contributed 
to  the  elevated  metals  in  this  sample.    Lead  was  detected  above the NC2LGWQS in all the 
groundwater samples, but was also identified above the NC2LGWQS in the field blank and the 
laboratory method blank. While total chromium was detected above the NC2LGWQS, speciation 
analysis  indicated  that  the  detected  concentrations  were  that  of  trivalent  chromium,  and  are 
therefore likely to be naturally occurring. 
Table 3 in Appendix B presents a summary of the groundwater analytical results from this event 
compared to the NC2LGWQS. The groundwater exceedances are shown on Figure 5. The laboratory 
analytical results are provided in Appendix C of this report.

SOIL‐GAS POINT INSTALLATION AND SAMPLING 
F&R advanced via a GeoProbe, seven temporary soil‐gas borings to five feet bgs to screen for 
methane with a landfill gas meter.  These borings were installed at the locations of historical 
geotechnical borings B‐103A and B‐105A(F&R Borings B‐4 and B‐2), three locations within the 
proposed building footprint (F&R Borings B‐7, B‐8 and B‐9), and two locations within the former 
quarry operation on the eastern portion of the Property (F&R Borings B‐3 and B‐5), as requested 
by the NCDEQ and shown on Figure 2.  Methane concentrations ranged from 0 to 56.8 percent 
as shown on Table 4 and Figure 6.   
Additionally, three soil‐gas borings were advanced for VOCs analysis via TO‐15 at the locations of 
former geotechnical borings B‐103A, B‐105A (B‐4 and B‐2), and the northwest corner of the 
proposed building (B‐7) to 20 feet bgs, i.e., a few feet above the water table in accordance with 
the NCDEQ Division of Waste Management (DWM) Vapor Intrusion Guidance Document (VIG) dated 
March  2018.    Groundwater  levels  in  the  monitoring  wells  were  measured  at  the  time  of 
installation  to  determine  of  the  appropriate  depth  for  installation  of  the  soil‐gas  points.  
Groundwater was measured between approximately 22 and 27 feet bgs (24 to 29 feet from top 
of casing). 
The soil‐gas samples were collected by installing an approximate 2‐inch diameter boring to a few 
feet above the capillary fringe based on water levels as determined during boring installation and 
historic groundwater levels.  The points were installed in accordance with the DEQ DWM Vapor 
Intrusion Guidance Document. The points consisted of a 6‐inch vapor sampling probe connected to 
dedicated Teflon sampling tubing inserted into the temporary soil‐gas boring points as proposed in 
the work plan. A gravel pack filter was installed around the vapor probe to 6 inches to 1 foot above 
the  top  of  the  probe,  followed  by  granular  bentonite  to  the  surface,  which  was  hydrated  in 
approximate 1‐foot intervals, and packed around the surface to form a seal. 
The soil‐gas samples were collected as generally recommended in EPA Soil‐Gas Sampling Operating 
Procedure.  The points were allowed to equilibrate for a minimum of 2 hours after installation prior 
to sampling.  The tubing was purged in conjunction with the helium leak test (discussed below) for 
a minimum of 5 minutes using an air pump at 0.2 L/min maximum (and three sample probe and 
tubing volumes) to ensure background air was removed from the tubing in accordance with the DEQ 
DWM Vapor Intrusion Guidance and EPA Soil‐Gas Sampling Operating Procedure. 
A helium leak test and a shut‐in test was performed to test the integrity of the seals and the soil gas 
sampling apparatus.  The helium leak test consisted of filling and sealing a shroud over the sample 
point and tubing after the tubing had been placed and sealed.  The shroud was filled to a minimum

 7 
of 50% helium.  A sample was drawn into a tedlar bag from the shroud and the sampling apparatus 
using a syringe.  A MGD 2002 helium gas detector was connected to the tedlar bag to check the 
helium concentration.  To be considered a good seal the helium concentration at the sample tubing 
must be less than 10% of the concentration in the shroud.  Helium concentrations in the sampling 
probe and tubing was less than 1% of the concentration in the shroud for the three soil‐gas points.  
The soil‐gas samples were collected using 1L batch certified Summa Canisters with flow controller 
calibrated at 0.2 L/min (approximately 5 minutes sampling time). 
The soil‐gas samples were analyzed for VOCs by Method TO‐15.  Upon completion the tubing was 
removed and the soil‐gas points sealed with bentonite. 
The soil‐gas samples collected detected multiple VOCs at concentrations above their laboratory 
reporting limits.  1,3‐Butadiene exceeded the Residential Soil Gas Screening Level (SGSL) of 14 
ug/M3 in sample B‐2 and the duplicate from that location with concentrations of 160 and 72 ug/M3, 
respectively. 1,3‐butadiene is typically found in urban areas and is associated with automobile, 
cigarette, and manufacturing exhaust, and production of rubber and plastics.  1,3‐butadiene was 
not identified in soil or groundwater at the Property.  Sample SB‐4 detected m/p‐xylene above the 
Residential SGSL. Other target compounds did not exceed their applicable Residential SGSLs.  Target 
compounds did not exceed the Non‐Residential SGSLs.  Table 4 in Appendix B presents a summary 
of the soil‐gas analytical results for this event. The Soil‐Gas exceedances are shown on Figure 7.  The 
laboratory analytical results are provided in Appendix C of this report.   
LABORATORY QA/QC 
A total of four soil samples plus a duplicate (5 total) were submitted to an independent North 
Carolina certified laboratory for analysis of volatile organic compounds (VOCs) by EPA method 
8260, semi‐volatile organic compounds (SVOCs) by EPA Method 8270, RCRA Metals by EPA 
Method 6020, and Hexavalent Chromium by EPA Method 7199. 
A total of three non‐filtered groundwater samples plus a duplicate (4 total) were submitted to an 
independent North Carolina certified laboratory for analysis of VOCs by EPA method 8260, SVOCs 
by EPA Method 8270, and RCRA Metals by EPA Method 6020.  
A total of three soil‐gas samples plus a duplicate (4 total) were submitted to an independent 
NVLAP accredited laboratory for analysis of VOCs by EPA Method TO‐15.   
As requested in the NCDEQ May 1, 2019 AAR, Level 2 QA/QC data packages were requested.  F&R 
requested that estimated values above the laboratory method detection limit (MDL) but above 

Adams Property  Brownfields Assessment Report

the laboratory reporting limit be reported by the laboratory with a ‘J’ flag.  Level 2 QA/QC data 
packages and ‘J’ flags were included in the laboratory data packages as requested. 
In addition, a single field and trip blank was collected per cooler for the soil and groundwater 
sampling in accordance with the approved work plan. 
INVESTIGATION DERIVED WASTE (IDW) MANAGEMENT 
The borings were backfilled with the soil cuttings and abandoned upon completion. Since no 
obvious indications of contamination were identified based on existing soil sampling data or 
during the soil borings or replacement monitoring well installation, soil cuttings were spread 
evenly on the land surface around the borings.  
Purge water from monitoring wells was filtered through carbon and discharged to the ground 
adjacent to the monitoring wells, since obvious contamination such as odors or elevated PID 
readings were not identified in the monitoring wells. 
RECEPTOR SURVEY
The Brownfields receptor survey did not identify sensitive receptors or wells within the applicable 
buffer distances. Several underground utilities were identified within 100 feet of the Brownfield 
boundary.  Based on the results of Soil‐Gas samples vapors are not anticipated to impact these 
receptors.  The Brownfields Receptor Survey is provided in Appendix E of this report.   
FINDINGS and CONCLUSIONS 
F&R provides the following findings and conclusions based on the limited assessment and sampling 
conducted: 
 Hexavalent chromium was detected in the soils at concentrations above the Residential PSRG 
of 0.31 mg/kg, at concentrations of 0.81 mg/kg (in B‐6) and 0.5 and 1.2 mg/kg (in B‐9 and the 
duplicate from B‐9).The concentrations detected did not exceed the commercial PSRG of 6.5 
mg/kg.  A low level of hexavalent chromium was also detected in the background sample at an 
estimated concentration (‘J’ flag) of 0.29 mg/kg.   
 Arsenic was detected at concentrations ranging from 2.6 to 20 mg/kg,  which  exceeds  its 
Residential and Commercial PSRGs.  The concentrations detected were generally consistent with 
the concentrations in the background sample (B‐10), indicating these detections are naturally 
occurring  except  in  sample  SB‐1  (from  boring  B‐1)  which  was  approximately  an  order  of 
magnitude greater than the background sample.   
 Several  SVOCs,  including  benzo(a)anthracene,  benzo(a)pyrene,  benzo(b)fluouranthene, 
dibenzo(a,h)anthracene,  and  indeno(1,2,3‐cd)pyrene  were  detected  above  their  respective

Residential PSRGs in the soil samples collected.  The concentrations detected did not exceed the 
non‐residential PSRGs.  
 Several VOCs, SVOCs and RCRA metals were detected in the groundwater at concentrations 
that exceeded the NC2LGWQS.  Hexavalent chromium was not detected above laboratory 
reporting limits.  The target compound concentrations did not exceed the GCLs except for 
lead in well MW‐3R.  Sample MW‐3R was noted to be slightly more turbid than the targeted 
turbidity of <10 NTU after purging which may have slightly contributed to the elevated metals 
in this sample.  Lead was also detected in the field and laboratory method blank. 
 1,3‐butadiene exceeded the Residential SGSL of 14 ug/M3 at a concentration of 73 and 160 
ug/M3 at 15 feet bgs at location B‐2.  1,3‐butadiene is typically found in urban areas and is 
associated with automobile, cigarette, and manufacturing exhaust, and production of rubber 
and plastics.  Sample SB‐4 detected m/p‐xylene above the Residential SGSL.  1,3‐butadiene and 
m/p xylene were not identified in soil or groundwater at the Property.   
 Methane concentrations raged from 0 to 56.8 percent at the property with the highest 
concentrations on the north‐central portion of the Property.
