1.0 INTRODUCTION
The Matheson Ave Creek (Site), listed at 255 Matheson Ave, Charlotte, NC 28206, is located east
of Matheson Avenue and south of North Tryon Street (Figure 1). The Site consists of an
approximately 6.1-acre parcel of land comprising an undeveloped creek corridor and forested
areas identified by Mecklenburg County tax identification number 08303151. The Site is being
managed under a Brownfields Agreement and referenced as Brownfields Project Number 23015-
19-060. The area included under the Brownfields Agreement was formerly part of a larger parcel
combining the east and west adjacent parcels (Matheson Ave II) and a separate Brownfields
Agreement has been negotiated with North Carolina Department of Environmental Quality
(NCDEQ) for that property (Brownfields Project Number 22042-18-060). The Site is bound to the
west and east by the Matheson Ave II property with commercial and industrial development
beyond. The Norfolk Southern AT&O Railway is located to the east and the southwest-flowing
Little Sugar Creek runs along a portion of the northern Site boundary and continues on to bisect
the western portion of the Site from the northeast to southwest. The Site is proposed to be
developed as open space and for recreational use, which includes a public greenway proposed
along the southern portion of the Site and a bridge proposed to connect the eastern and western
adjacent Matheson Ave II property across Little Sugar Creek.
Previous investigations and Brownfields Program support activities have been conducted on the
adjacent Matheson Ave II development property to the east and west of the Site as well as on the
Site when it was part of the combined property. This report documents additional assessment
activities performed at the request of the Brownfields Program, which included additional soil,
sediment, and groundwater sampling to evaluate potential impacts from petroleum releases
observed originating from the adjacent Queen City Metal Recycling and Salvage facility to the
northeast and fill material present south of the Site, near the proposed public greenway
development. These activities were conducted by Apex Companies, LLC (Apex) in accordance
with Apex’s Work Plan for Additional Environmental Assessment dated April 12, 2019 and
approved by the Brownfields Program in an email dated April 20, 2019.

2.0 BACKGROUND
Previous reports for the Site and the adjacent Matheson Ave II property include a Phase I
Environmental Site Assessment (2014 Phase I) and a Limited Phase II Environmental Site
Assessment (2014 Phase II) performed by Hart & Hickman (H&H) in November 2014 and
Limited Phase II Environmental Site Assessment September 2019 Matheson Ave. Creek Page 2
Apex Companies, LLC  10610 Metromont Parkway, Suite 206  Charlotte, NC 28269  T 704.799.6390  F 704.799.6395  apexcos.com
December 2014 respectively. The 2014 Phase I indicated that approximately 50 percent of the
combined Site and Matheson Ave II development property is covered with fill material of unknown
origin. The 2014 Phase I also identified a nearby business, Detrex, as a facility located
topographically cross-gradient to the Site that stores and sells solvents and has documented
impacts to Little Sugar Creek surface water and sediment upstream of the Site. Key Site features,
areas of fill material, and nearby properties are depicted on Figure 2.
Based on the potential impacts from the environmental concerns noted in the 2014 Phase I, H&H
conducted a 2014 Phase II, which consisted of soil borings installed in various sections of the
identified off-site fill material. The results of the 2014 Phase II identified several metals at
concentrations above NCDEQ Inactive Hazardous Sites Branch (IHSB) Preliminary Soil
Remediation Goals (PSRGs) for residential use. The metal exceedances were considered to be
attributed to naturally occurring background concentrations except for one lead result, from a
sample collected in the northwestern portion of the Matheson Ave II property.
Based on identified impacts to the Site and Matheson Ave II properties and the limited scope of
the 2014 Phase II, Apex recommended further investigation, which was completed in November
2017. As part of this investigation, Apex conducted soil, groundwater, and surface water
assessment activities. The November 2017 investigation identified arsenic above residential
PSRGs in all on-site soil samples. Tetrachloroethylene (PCE), trichloroethylene (TCE), and vinyl
chloride were identified in surface water samples from Little Sugar Creek at concentrations above
the surface water standards contained within Title 15A of the North Carolina Administrative Coded
(NCAC) Subchapter 2B (2B Standards). Semi-volatile organic compounds (SVOCs) were
discovered in one surface water sample collected from the Little Sugar Creek immediately
downstream of a surficial oil release observed on the adjacent Queen City Metal Recycling and
Salvage facility. Bis(2-ethylhexyl)phthalate was identified at a concentration above the Title 15A
of the NCAC Subchapter 2L Groundwater Quality Standard (2L Standard) in one groundwater
sample and chromium was identified at a concentration above the 2L Standard in one other
groundwater sample.
3.0 FIELD ACTIVITIES AND SAMPLING METHODOLOGY
In anticipation of the proposed development activities on the Site, the additional soil and
groundwater assessment activities were conducted in May 2019 to assess potential impacts of
observed petroleum releases from the northeast adjacent Queen City Metal Recycling and

Salvage facility and to further evaluate the effects of fill material near the proposed public
greenway development area.
3.1 Soil Assessment
Soil Assessment Methods
North Carolina One Call was notified prior to initiating drilling activities to identify the locations of
underground utilities. On May 2, 2019 soil boring activities were conducted at four locations at
the Site, SB-7, SB-8, SB-9, and SB-10. Soil boring and well installation services were provided
by Carolina Soil Investigations of Olin, North Carolina using a hand auger. Sampling locations
are shown on Figure 3.
Three of the borings (SB-7, SB-8, and SB-9) were advanced to a depth of five feet below ground
surface (bgs) using a hand auger along the south side of Little Sugar Creek, evenly distributed
from east to west in the approximate location of the proposed greenway development. The fourth
soil boring (SB-10) was advanced to a depth of 5 feet bgs in the northwest portion of the Site, to
evaluate an area potentially impacted by the adjacent metals recycling facility. Soil borings were
logged continuously from ground surface to the bottom of each borehole by an experienced Apex
environmental scientist who documented the subsurface conditions (soil type, volatile emissions
measured using a photoionization detector (PID), the presence of odors/staining, groundwater
levels, etc.) in each boring. A soil sample was collected from within the vadose zone at each
boring location based on visual observations and/or elevated PID readings. Boring logs showing
lithology, sample intervals, and PID reading for each screening interval are provided as
Appendix A.
In addition to the above, two sediment samples (SS-1 and SS-2) were collected on May 3, 2019
from the upper 6-inches of stream sediment within an on-site intermittent streambed north of Little
Sugar Creek near the northern border of the Site. The intermittent stream receives surface run-
off from the Queen City Metal Recycling and Salvage facility but was dry at the time of sampling.
Soil samples were collected in appropriately labeled laboratory-supplied bottle ware and stored
on ice in a cooler. Samples were delivered under standard chain-of-custody protocol to Shealy
Environmental Services, Inc. (Shealy) of West Columbia, South Carolina for analysis of volatile
organic compounds (VOCs) by EPA Method 8260/5035, SVOCs by EPA Method 8270, and
RCRA Metals and hexavalent chromium by EPA Method 6010 and EPA Method 7470. In addition
to the aforementioned parameters, sediment samples and the soil sample collected from SB-10

were analyzed for polychlorinated biphenyls (PCBs) by EPA Method 8082. Copies of the
laboratory analytical results and associated chain-of-custody are included in Appendix B.
Soil Assessment Results
Soil analytical results are presented in Table 1 and were compared to the PSRGs for residential
exposure, industrial/commercial exposure, and protection of groundwater. A total of 27 analytes
were detected by the lab during the analysis of the four soil samples and two surface sediment
samples, six of the analytes were identified at concentrations greater than one or more PSRG.
Of the nine metals detected in the six soil/sediment samples, arsenic and hexavalent chromium,
were detected at concentrations exceeding one or more PSRG. Hexavalent chromium
concentrations detected in the six soil/sediment samples ranged from 2.2 to 4.8 milligrams per
kilogram (mg/kg), all of which exceeded the residential PSRG of 0.31 µg/kg. None of the detected
concentrations of hexavalent chromium exceeded the industrial/commercial PSRG of 6.5 mg/kg.
Arsenic was detected at concentrations ranging from 1.4 to 7.1 mg/kg, all of which exceeded the
residential PSRG of 0.68 mg/kg. Concentrations of arsenic exceeded the industrial/commercial
PSRG of 3.0 mg/kg at SB-9, SB-10, SS-1, and SS-2.
Fifteen SVOCs were detected in the six soil/sediment samples, all of which were detected in the
samples along the northwestern portion of the Site (SB-10, SS-1, and SS-2). Of the detected
SVOCs, four were at concentrations exceeding one or more PSRG including benzo(a)anthracene,
benzo(a)pyrene, benzo(b)fluoranthene, and indeno(1,2,3-c,d)pyrene. Benzo(a)pyrene was
detected at SS-1 at a concentration of 3,000 micrograms per kilogram (µg/kg), exceeding the
industrial/commercial PSRG of 2,100 µg/kg. All other exceedances of SVOCs were above
residential PSRGs but below industrial/commercial PSRGs.
Two VOCs were detected in select samples, acetone and 1,1-dichloroethene. Neither compound
was detected at concentrations exceeding any of the PSRGs.
The three samples on the northwest side of the Site (SB-10, SS-1, and SS-2) also contained low
concentrations of the PCB, Aroclor 1260. All three detections were below the residential PSRG.
3.2 Groundwater Assessment
Upon the completion of collecting a soil sample from SB-10, a temporary monitoring well (MW-10)
was installed to a depth of 6 feet bgs; groundwater was encountered at approximately 1.5 feet.
Limited Phase II Environmental Site Assessment September 2019 Matheson Ave. Creek Page 5
Apex Companies, LLC  10610 Metromont Parkway, Suite 206  Charlotte, NC 28269  T 704.799.6390  F 704.799.6395  apexcos.com
The well was developed for 20 minutes with a peristaltic pump and allowed to stabilize overnight
to reduce the amount of turbidity in the well. On May 3, 2019, Apex returned to the Site and
collected a groundwater sample (MW-10) utilizing low flow sampling techniques. This well was
abandoned by the installers upon completion of sampling activities.
During sample collection, field data parameters including pH, specific conductivity, oxidation-
reduction potential, and turbidity were collected. The groundwater samples were collected in the
appropriate laboratory-supplied bottleware and stored on ice in a cooler. Samples were delivered
to Shealy using standard chain-of-custody protocol. The samples were analyzed for VOCs by
EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Method 6010, and
hexavalent chromium by EPA Method 7470. Copies of the laboratory analytical results and
associated chain-of-custody are included in Appendix B.
Groundwater analytical results are summarized in Table 2. Lab results were compared to the
NCAC 2L Groundwater Quality Standards, the NC Interim Maximum Allowable Concentrations,
and the NCDEQ Division of Waste Management October 2017 Residential and Non-Residential
Groundwater to Indoor Air Vapor Intrusion Screening Levels (VISLs).
Barium was the only constituent detected, which was detected at a concentration of 0.10
milligrams per liter (mg/l) in MW-10, below the respective 2L Standard of 0.7 mg/l.
3.3 Surface water Assessment
The approved workplan included the collection of a surface water sample, if present, from the
intermittent stream traversing the northwest portion of the Site. At the time of fieldwork for this
assessment, the streambed was dry and no sample was collected.
4.0 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)
The following quality assurance/quality control (QA/QC) measures were applied during the
sampling events:
• Expendable sampling material such as tubing was not reused between samples.
• Field personnel donned gloves when collecting samples and/or handling sample tubing.
• Non-expendable sampling equipment was decontaminated between each sample.
• Duplicate samples were collected for all analytical methods including one duplicate soil
sample and one duplicate groundwater sample. Duplicate sample results were generally

Apex Companies, LLC  10610 Metromont Parkway, Suite 206  Charlotte, NC 28269  T 704.799.6390  F 704.799.6395  apexcos.com
similar to sample analytical results although the soil duplicate of SB-9 (2-4 ft) contained
acetone above the Lowest Detection Quantity (LOQ). Acetone is a common laboratory
artifact.
• A trip blank was shipped along with the water samples and analyzed for VOCs by EPA
Method 8260, the results of which were non-detect for all associated analytes.
• Equipment blanks consisting of deionized water poured through the groundwater sample
tubing and the decontaminated soil sampling equipment were collected and analyzed for
all parameters. Chloroform was detected in both equipment blank samples (EB1-
05022019 and EB2-05022019) and bis(2Ethylhexly)phthalate was detected in EB1-
05022019. Both constituents were below their respective 2L Standards and neither were
identified in any of the soil, sediment, or groundwater samples collected.
5.0 SUMMARY AND CONCLUSIONS
The results of the soil and groundwater sampling suggests that the Site has been impacted by
petroleum-related compounds at concentrations exceeding one or more PSRG in the northwest
portion of the Site, presumably from releases associated with the adjacent metals recycling
facility. Additionally, concentrations of chromium and arsenic exceeded one or more PSRG
throughout the Site. Detected concentrations of metals were generally consistent with those
observed in previous investigations on the Site and adjacent Matheson Ave II property and are
considered to be representative of naturally occurring conditions. There were no analytes
detected in groundwater above applicable PSRGs.
The Site is proposed to be developed as a recreational property with a greenway and a road with
a bridge connecting the two portions of the adjacent Matheson Ave II property. The greenway is
proposed on the southern and southeastern portions of the Site, away from the observed
petroleum-related impacts in the northwest portion of the Site. To evaluate potential risk from
exposure to contaminated soil, the highest concentration of each detected analyte among the six
soil/sediment samples was entered into the NCDEQ Risk Calculator, May 2019 Version. The
sitewide carcinogenic risk, calculated using the highest concentrations of contaminants identified
in this study was 6.1 x 10-5 for residential exposure, 5.1 x 10-6 non-residential worker exposure,
2.0 x 10-6 for construction worker exposure, and 3.4 x 10-5 for recreator/trespasser exposure
scenarios. The calculated carcinogenic risk for each of the exposure scenarios is below the target
risk threshold of 1.0 x 10-4. The sitewide hazard index was calculated at 4.4 x 10-1 for residential
exposure, 3.5 x 10-2 for non-residential worker exposure, 6.0 x 10-1 for construction worker, and

2.4 x 10-1 for recreator/trespasser exposure scenarios. The calculated hazard index for each of
the exposure scenarios is below the target hazard index threshold of 1.0. Based on the results
of this assessment, the sitewide risk associated with shallow soil is below all applicable target
thresholds. The risk calculator output sheets are included as Appendix C of this report.

Assurance Management Plan (QAMP),standard operating procedures (SOPs),and Shealy policies.Any
exceptions to the NELAC standards,the QAMP,SOPs or policies are qualified on the results page or
discussed below.
Where applicable,all soil sample analysis are reported on a dry weight basis unless flagged with a "W"
qualifier
If you have any questions regarding this report please contact the Shealy Project Manager listed on the
cover page.
Hexavalent Chromium
Due to matrix interference the martix spike /matrix spike duplicate (MS/MSD)associated with analytical
batch 16092 was outside of the recovery acceptance criteria.Although,the RPD%and the batch
laboratory control spike (LCS)was within acceptance criteria;therefore,the data have been reported.
RCRA Metals
The following samples were diluted due to the nature of the sample matrix due:UE04035-002,UE04035-
003,UE04035-006,UE04035-007.The LOQ has been elevated to reflect the dilution.
VOCs by GC/MS
Internal standard response for the following sample exceeded the lower control limit:UE04035-004.The
sample was re-analyzed with concurring results.As such,the sample results may be biased high.The
original set of data has been reported
The laboratory control sample (LCS)for analytical batch 16387 exceeded acceptance criteria for Acetone.
This analyte is biased high but not detected in the samples affected.
The continuing calibration verification (CCV)associated with analytical batch 16387 recovered outside
acceptance criteria,for Vinyl Chloride and Acetone.An LOQ standard was analyzed,and the target
analyte was detected.Since the associated samples are non-detect,no corrective action was taken.

VOCs by GC/MS
The laboratory control sample (LCS)for analytical batch 16387 exceeded acceptance criteria for Acetone.
This analyte is biased high but not detected in the samples affected.
The continuing calibration verification (CCV)associated with analytical batch 16387 recovered outside
acceptance criteria,low biased,for Vinyl Chloride.An LOQ standard was analyzed,and the target
analyte was detected.Since the associated samples were non-detect,no corrective action was taken.
The continuing calibration verification (CCV)associated with sample UE04020-003,UE04020-004,
UE04020-006 recovered Acetone above the upper control limit.The samples associated with this CCV
were non-detect for the affected analytes;therefore,the data has been reported.
