Brownfields Project No. 24007-20-032
ECS Project No. 49-10039-B
Dear Ms. Samaha-Smith,
ECS Southeast, LLP (ECS) has prepared this environmental letter report of post -excavation results associated
with surficial soils impacted from runoff believed to be associated with an upgradient incident that occurred
at 719 Rigsbee Avenue in Durham, North Carolina, located adjacent and south of the Wright's Executive Sales
II Brownfields site (the "Site"). Included in this report is a description of the field activities, the results
obtained, and our conclusions and recommendations.
ECS appreciates the opportunity to provide our environmental consulting services. If you have any questions
concerning this report project, please contact us.
BACKGROUND INFORMATION
On November 12, 2022, after rainfall infiltrated existing in -ground hydraulic lifts following demolition
activities of the former garage building, a suspected hydraulic oil release was discovered at 719 Rigsbee
Avenue. Hydraulic oil was discovered downgradient on Wright's Executive Sales II Brownfields Property
at 721 and 723 Rigsbee Avenue; 616 and 620 Foster Street (PINs 0822-90-31-8262 and 0821-99-29-7413,
see Figures 1 and 2) and impacted surficial soil on the property within the flow path of the runoff.
On November 14, 2022, ECS contracted with Terra Nova Solutions (Terra Nova, previously Zebra
Environmental) to recover approximately 2,001 gallons of free product and impacted liquid from the
release site at 719 Rigsbee using a vacuum truck. Oil -soaked debris was placed into a lined roll -off box
staged at the 719 Rigsbee release site property for future disposal. ECS collected soil samples of impacted
surficial soil at the site at 719 Rigsbee Avenue for Total and TCLP analysis of volatile organic compounds
(VOCs) by EPA Method 8260, semi -volatile organic compounds (SVOCs) by EPA Method 8270, Metals, and
PCBs (total only) for disposal characterization purposes. ECS personnel subsequently conducted field

screening throughout the observed flow path of the release on the Brownfields Site using a photo -
ionization detector (PID) in an effort to delineate soil impacts. ECS identified the impacted area to be
approximately 1,000 feet long and ranged in width from approximately 10 feet to 21 feet wide. ECS
identified the depth of impacted soil to be approximately half a foot in depth, based on PID readings of
soil taken at the surface and at 0.5 ft intervals below the surface using the PID. The hydraulic fluid flowed
to the west from the source area until encountering the southwestern corner of the new building
construction. Upon reaching the building, the hydraulic fluid changed direction to flow north along Foster
Street and the new building. A map illustrating the area affected by the release and PID screening locations
is provided in Figure 3. A table summarizing field screening results on November 14, 2022 is provided in
Table 1. Oil -only booms were installed and replaced as needed in an effort to contain the release, and oil -
only pads were utilized to pad up visibly impacted surfaces on the flow path of the release. On November
17, 2022, ECS continued to install and replace oil -only booms and pads in the area of the release, and
spent booms and pads were placed in the lined roll -off box for future disposal. A containment pit was
constructed where flow was observed as daylighting at the northwestern corner of the 719 Rigsbee site
(as depicted in Figure 3) in an effort to prevent further run-off onto the Brownfields Property at 721 and
723 Rigsbee Avenue; 616 and 620 Foster Street. Between November 17, 2022, and November 28, 2022,
impacted liquids were removed by Terra Nova using a vacuum truck on an as -needed basis, and
approximately 5,450-gallons of liquid were removed in that timeframe.
FIELD ACTIVITIES
On December 1, 2022, ECS provided a project professional to oversee the excavation of impacted soil
along the flow path of the hydraulic oil release at the property on 721 and 723 Rigsbee Avenue; 616 and
620 Foster Street. A map showing the approximate area of surficial soil impacted from the release is
illustrated in Figure 3 The top 6-inches of soil from approximately half of the flow path on the Brownfields
Property was removed using an excavator provided by Terra Nova, and was temporarily stockpiled on -site
in accordance with the Site's Brownfield Approved Environmental Management Plan (EMP). The western
portion of hydraulic oil impacted soil was not excavated on December 1, 2022 due to shoring along and
in the building under construction along Foster Street which prevented initial abatement soil excavation
activities to occur without compromising the shoring system's integrity. The areas of soil excavation and
post -excavation sampling are illustrated in Figure 4. Photographic documentation of field activities is
provided in Attachment A.
The impacted soil along the flow path of the hydraulic oil release was excavated by Terra Nova. ECS
personnel identified the areas of impact to be remediated using flow path measurements that were
obtained on November 14th, 2022 by visually identifying the area of fluid flow, which were confirmed via
field screening delineation efforts (see Figure 1). An impacted root ball was also removed and stockpiled
on site. The soil was temporarily stockpiled by first segregating the soil, which was then placed on plastic
sheeting and bermed off in order to prevent runoff. A second layer of plastic sheeting was placed on top
of the impacted soils and secured with cinderblocks. Terra Nova began hauling the stockpiled soil on
December 5th, 2023 to Earthtec Environmental, Inc. (Earthtec), a permitted soil treatment facility in Bear
Creek, North Carolina (Permit No. SR050002). Soil analytical data from the impacted surficial soil at 719
Rigsbee Avenue was utilized to profile the waste stream for soil excavated at the Brownfields Property. A
total of 85.54-tons of impacted soil was hauled off in four loads. Copies of the non -hazardous waste
manifests are provided in Attachment B. The root ball was disposed of at Republic Services Upper
Piedmont Environmental Landfill in Rougemont, NC.
The western portion of the hydraulic oil spill was subsequently excavated on March 27, 2023 following
removal of shoring along the building which allowed access to the areas necessitating further excavation
N

(Figure 4). The impacted soil was excavated by the construction site's general contractor, Clancy and Theys
(C&T). The top 6-inches of soil from the remaining areas of the hydraulic oil release flow path were
excavated with an excavator provided by C&T. ECS provided a project professional to oversee the
remediation efforts. C&T stockpiled soil on site and placed plastic sheeting over the stockpile overnight
to prevent runoff. Once the stockpile was completely hauled off site, C&T excavated soil at the base of
the former stockpile to a depth of approximately 0.5 feet below ground surface and loaded the soil directly
into a dump truck for removal. A total of 57.89 tons of hydraulic fluid contact soil was hauled to Earthtec
in three loads on March 28, 2023. Copies of the non -hazardous waste manifests are provided in
Attachment B. The excavated areas were not backfilled, due to the shallow depth of the grade removed
during excavation activities.
After excavation activities were completed on December 1, 2022 and March 27, 2023, ECS personnel
collected four (4) representative 5-point composite soil samples (two for each day of excavation) and two
(2) duplicate soil samples (one for each day of excavation) from the base of the excavation. Due to the
shallow depth of excavation (0.5 ft below ground surface), sidewall samples were not collected from the
excavation. The excavated areas were gridded into four sections (PE-1 through PE-4), and five grab
samples with duplicate aliquots were obtained from the top 6 inches of soil in each section. The post -
excavation samples identified as PE-1 and PE-2 were collected on December 2, 2022. The post -excavation
samples identified as PE-3 and PE-4 were collected on March 27, 2023. The duplicate soil sample (DUP-1)
collected on December 1, 2022 was obtained as a duplicate of PE-1. The duplicate soil sample (PE-DUP)
collected on March 28, 2023 was obtained as a duplicate of PE-3. The grab samples were collected using
a decontaminated stainless -steel shovel, and temporarily placed in new, dedicated, 4-oz amber glass jars
in an effort to minimize potential VOC loss in the samples until further sampling. The duplicate aliquots
were placed into plastic bags and were subsequently screened using a PID for volatile soil vapors after at
least 15 minutes upon duplicate sample collection to allow vapors to volatilize into the headspace of the
plastic bag. The duplicate aliquots were considered to be ineligible for sampling. The individual grab soil
sample with the highest associated PID reading was appropriately packaged and submitted to Eurofins, a
North Carolina certified laboratory (NC Certification No. 269), located in Savannah, GA to be analyzed for
VOCs using EPA Method 8260. Subsequently, the aliquot was then gently mixed with the other four
aliquots and one representative composite soil sample was created by placing the soil aliquots onto a
dedicated, new, disposable aluminum tray. The soils on the tray were subsequently gently mixed by ECS
personnel by hand, and wearing dedicated, new nitrile gloves. The composite samples were containerized
for analysis of SVOCs by EPA Method 8270, Resource Recovery and Conservation Act (RCRA) 8-metals by
EPA Method 6020/7471, and hexavalent chromium (Cr-VI) by EPA Method 7199. The areas of post -
excavation sampling are illustrated in Figure 4. A copy of the chain -of -custody documentation is included
in Attachment C.
III. LABORATORY ANALYSIS
The laboratory analysis of the sample PE-1, PE-2, PE-3, PE-4, PE-DUP, and DUP-1 indicated arsenic at
concentrations above its respective Residential North Carolina Department of Environmental Quality
(NCDEQ) Residential Preliminary Soil Remediation Goal (PSRG). According to Dragun and Chekiri's
Elements in North American Soils, Second Edition, naturally occurring concentrations of arsenic range
from 1.0 milligram per Kilogram (mg/Kg) to 18 mg/Kg with a mean concentration of 2.07 mg/Kg. Arsenic
concentrations reported above the Residential PSRG ranged from 1.18 mg/Kg in PE-2 to 3.08 mg/Kg in PE-
1 and are within the referenced naturally occurring arsenic ranges. It is the opinion of ECS that the arsenic
concentrations reported as a result of this assessment are not associated with the suspected release.
[c3

The laboratory analysis of the sample PE-1 through PE-4, PE-DUP and DUP-1 indicated Cr-VI at
concentrations above its respective Residential PSRG. The USEPA Contaminated Site Cleanup Information
(CLU-IN) Chromium VI Overview dated October 26, 2018 indicates that "chromium is abundant in nature
and is generally found as trivalent chromium (Cr III) or Cr VI. Cr VI is most often produced by industrial
processes and may be an indicator of environmental contamination. This form exists in oxidizing
conditions and can move down through soil to underlying groundwater. The concentration of naturally
occurring chromium in US soil range from 1 to 2,000 parts per million (ppm)". As such, ECS opines that
the Cr VI concentration reported in the record sample is not representative of actual site conditions, and
representative of naturally occurring or anthropogenic background concentrations.
Laboratory analysis of sample PE-1 indicated acetone, carbon disulfide, benzo[a]anthracene,
benzo[b]fluoranthene, chrysene, fluoranthene, phenanthrene, pyrene, selenium, silver, and mercury at
concentrations above the laboratory method detection limit, but below their respective Residential
PSRGs. The lab analysis for PE-1 also indicated barium, cadmium, trivalent chromium, lead, selenium,
silver, and mercury at concentrations above laboratory method detection limits, but below their
respective Residential PSRGs.
Laboratory analysis of the sample PE-2 indicated acetone, benzo[a]anthracene, benzo[b]fluoranthene,
chrysene, fluoranthene, phenanthrene, and pyrene at concentrations above the laboratory method
detection limit, but below their respective Residential PSRGs. The lab analysis for PE-2 also indicated
barium, cadmium, trivalent chromium, lead, selenium, silver, and mercury at concentrations above
laboratory method detection limits, but below their respective Residential PSRGs.
The laboratory analysis of PE-3 indicated acetone, benzene, hexane, toluene, benzo[a]anthracene, bis(2-
ethylhexyl) phthalate, chrysene, fluoranthene, and pyrene at concentrations above the laboratory
method detection limit, but below their respective Residential PSRGs. The lab analysis for PE-3 also
indicated barium, cadmium, trivalent chromium, lead, selenium, silver, and mercury at concentrations
above laboratory method detection limits, but below their respective Residential PSRGs.
Laboratory analysis of the sample PE-4 indicated acetone, 2-butanone, benzo[a]anthracene, bis(2-
ethylhexyl) phthalate, chrysene, fluoranthene, and pyrene at concentrations above the laboratory
method detection limit, but below their respective Residential PSRGs. The laboratory analysis for PE-4
also indicated barium, cadmium, trivalent chromium, lead, selenium, silver, and mercury at
concentrations above laboratory method detection limits, but below their respective Residential PSRGs.
Laboratory analysis of the sample PE-DUP (taken as a duplicate of PE-3) indicated acetone, hexane,
benzo[a]anthracene, and caprolactam above the laboratory method detection limit, but below their
respective Residential PSRGs. The laboratory analysis for PE-4 also indicated barium, cadmium, trivalent
chromium, lead, selenium, silver, and mercury at concentrations above laboratory method detection
limits, but below their respective Residential PSRGs.
Laboratory analysis of the sample DUP-1(taken as a duplicate of PE-1) indicated acetone, carbon disulfide
benzo[a]anthracene, benzo[b]fluoranthene, chrysene, fluoranthene, phenanthrene, and pyrene at
concentrations above the laboratory method detection limit, but below their respective Residential
PSRGs.
A copy of the laboratory analytical data and associated chain of custody (COC) are included in Attachment
C. The soil laboratory data are summarized in Table 2. Field notes collected during the assessment have
been included as Attachment D.

IV. INVESTIGATION DERIVED WASTE
Little to no soil investigative derived waste (IDW) was generated during the assessment given the nature
of the surficial impacts. What was produced was spread on the surface near each respective sampling
location. IDW was produced only from soil screened at the base of excavated areas (which were presumed
to be deeper than the area of impacted soil on site). Because of this, as well as the fact that only a relatively
small amount of IDW was produced, IDW was not added to the stockpile of excavated soil to be hauled
off.
V. QUALITY ASSURANCE/QUALITY CONTROL
Two sample duplicates were collected to support QA/QC of this assessment. The duplicates, identified as
DUP-1 and PE-DUP, were submitted for the same media and laboratory analyses as the sample they
duplicated (PE-1 and PE-3 respectively).
Following sample collection, the sample containers were labeled and maintained under COC until
delivered to Eurofins in Raleigh, NC by local courier. Upon being containerized, the samples were
immediately placed in a cooler with ice to maintain the samples at or below approximately 4°C. A COC
document was utilized throughout the collection and transportation of the samples.
Review of the duplicate sample (DUP-1) data presented herein indicates that the SVOC constituents
benzo[a]anthracene, benzo[b]fluoranthene, chrysene, fluoranthene, phenanthrene, and pyrene were not
detected above laboratory method detection limits, as they were in the duplicated sample PE-1. It should
be noted that the concentrations of the SVOC constituents in PE-1 were estimates, due to the fact that
the concentrations of the constituents did not exceed their respective laboratory reporting limits.
Therefore, the lack of SVOC detections in the duplicate DUP-1 compared to its duplicated sample PE-1
have not affected the interpretations of those results. Cr VI was reported to be an approximate order of
magnitude higher in the record sample identified as PE-1 than in its duplicate sample identified as DUP-1.
A comparison of other analytical results for metals analyzed by EPA Method 6020/7471 obtained from
the record sample (PE-1) and its duplicate (DUP-1) appear to be similar and have not affected the
interpretation of those results. ECS opines that the Cr VI concentration reported in the record sample is
not associated with the suspected release.
Review of the duplicate sample (PE-DUP) data presented herein indicates that the SVOC constituents
Bis(2-ethylhexyl)phthaIate, chrysene, fluoranthene, and pyrene were not detected above laboratory
method detection limits, as they were in the duplicated sample PE-3, and caprolactam was detected in
PE-DUP and not PE-3. It should be noted that the concentrations of the SVOC constituents in PE-3 were
estimates, due to the fact that the concentrations of the constituents did not exceed their respective
laboratory reporting limits. Therefore, the lack of SVOC detections in the duplicate DUP-1 compared to its
duplicated sample PE-1 have not affected the interpretation of those results. The VOC constituents
benzene and toluene were not detected in DUP-PE as they were in PE-3. Trivalent chromium (Cr III) was
reported to be an approximate order of magnitude higher in the record sample identified as PE-3 than in
its duplicate sample identified as PE-DUP. A comparison of other analytical results for metals analyzed by
EPA Method 6020/7471 obtained from the record sample (PE-3) and its duplicate (PE-DUP) appear to be
similar and have not affected the interpretation of those results. ECS opines that the Cr III concentration
reported in the record sample is not associated with the release from the suspected release.

VI. CONCLUSIONS AND RECOMMENDATIONS
• On December 1, 2022, Terra Nova excavated impacted soil at the Brownfields property along the flow
path of the suspected hydraulic oil release beginning at the adjacent upgradient property located at
719 Rigsbee Avenue and heading west to Foster Street in Durham, NC. A total of 85.54-tons of
impacted soil were hauled to Earthtec in December 2022. The western portion of the affected area
was obstructed by construction shoring at the time and could not be accessed by an excavator until
March 2023.
• ECS collected two (2) 5-point representative composite samples and one (1) duplicate sample from
the base of the excavation of the eastern portion of the affected surficial soil on December 2, 2022.
The soil samples were analyzed for VOCs by EPA Method 8260, SVOCS by EPA Method 8270, RCRA-8
metals by EPA Method 6020/7471, and Cr VI by EPA Method 7199.
• On March 28, 2023, the western portion of impacted soil along Foster Street was excavated following
removal of construction shoring in the area by the site's general contractor, C&T. A total of 57.89 tons
of hydraulic fluid contact soil was hauled to Earthtec on March 28, 2023. ECS collected two (2) 5-point
representative composite samples and one (1) duplicate sample from the base of the excavation on
March 28, 2023. The soil samples were analyzed for VOCs by EPA Method 8260, SVOCS by EPA Method
8270, RCRA-8 metals by EPA Method 6020/7471, and Cr-6 VI by EPA Method 7199.
• The laboratory analysis of PE-1 through PE-4, PE-DUP, and DUP-1 indicated arsenic at concentrations
above its respective Residential PSRG, and PE-1 indicated arsenic above its Industrial/Commercial
PSRG. It is ECS' opinion that the presence of arsenic in the soil samples is representative of suspected
naturally occurring or anthropogenic background concentrations, and not associated with the release
from the adjacent upgradient 719 Rigsbee site.
• The laboratory analysis of the sample PE-1, PE-2, and DUP-1 indicated Cr VI at concentrations above
its respective NCDEQ Residential PSRG. It is ECS' opinion that the presence of Cr VI in the soil samples
is not associated with the suspected release from the adjacent upgradient 719 Rigsbee site.
• Except for the arsenic and Cr VI detections described above, no other VOC, SVOC, or RCRA-8 metals
constituents analyzed by EPA method 8260, 8270, and 6020/7141 respectively were detected above
their respective Residential PSRGs in PE-1 through PE-4, DUP-1, and PE-DUP.
• It is ECS' opinion that the soil excavation activities that occurred on December 1, 2022 and March 28,
2023 were successful in remediating the horizontal and vertical extents of hydraulic oil impacts from
the suspected release at 719 Rigsbee Avenue to Foster Street in Durham, NC. The horizontal and
vertical extents of soil requiring remediation was determined using flow path measurements that
were obtained on November 14, 2022 by visually identifying the flow path of the release. These limits
were subsequently confirmed via PID field screening efforts.

Notes:
Results are presented in milligrams per Kilogram (mg/Kg), analogous to parts per million (ppm).
Only those constituents detected in at least one sample are listed above. For complete results, refer to laboratory report.
ft bgs = feet below ground surface
NCDEQ= North Carolina Department of Environmental Quality
J = Result is less than the RL but greater than or equal to the MDL and the concentration is an approximate value.
PSRG = Preliminary Soil Remediation Goals as of January, 2023
VOC = Volatile Organic Compounds
SVOC = Semi -Volatile Organic Compounds
NS = No Standard
Bold denotes concentration is in exceedance of Residential PSRG
F1 = MS and/or MSD recovery exceeds control limits.
F2 = MS/MSD RPD exceeds control limits
* Trivalent chromium was calculated by subtracting the concentration of hexavalent chromium from the concertation of (total) chromium reported by the laboratory.

Receipt
The samples were received on 3/27/2023 1:25 PM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.8°C
GC/MS VOA
Method 8260D: The following terra core vials are overweight: -2C, -4A, 4C and-613.PE-3 VOC (752-4861-2), PE-4 VOC (752-4861-4) and
DUP- VOC (752-4861-6)
Method 8260D: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with
preparation batch 680-770530 and analytical batch 680-770526.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC/MS Semi VOA
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
HPLC/IC
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Metals
Method 7471 B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 680-770729 and analytical batch
680-770831 were outside control limits for one or more analytes, see QC Sample Results for detail. Sample matrix interference and/or
non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
General Chemistry
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
