2.3 Release Information
Date Discovered:January 1, 1988
Estimated Quantity of Release:approximately 17,000 gallons
Cause of Release:7/8-inch long by 1/16-inch wide split along pipeline
Source of Release:8” underground pipeline
2.4 Site Characteristics
2.4.1 Historical Release Information and Risk Classification
The released product was identified as gasoline and diesel. NCDEQ assigned an incident number (3571)
to the Site and risk classification of “intermediate” due to the proximity of Lake Brandt and presence of
LNAPL in Site monitoring wells.
2.4.2 Land Use
The Site is located in a residential portion of Guilford County. The Site is now situated on a single parcel
(Number 89076) owned by PPL and is approximately 1.85 acres in size. The Site is located within a
residential neighborhood and is bounded by a wooded area and greenway to the northwest and by
2022 Semiannual Report
February 2023 AECOM2-2
private residential properties to the northeast, southeast, and southwest. The Site has a surface elevation
of approximately 800 feet above mean sea level based on the topographic map. The land surface at the
Site slopes moderately to the west (towards Lake Brandt) and steeply to the north (towards the
stormwater channel).
2.4.3 Remedial History
Site remediation began immediately after discovery of the release. Initial response efforts recovered
approximately 6,000 gallons of LNAPL. In 1988, a pump-and-treat (P&T) system was installed and
operated utilizing eight (8) recovery wells. Seventeen (17) additional recovery wells, two (2) soil vapor
extraction (SVE) wells, and nineteen (19) dual-phase wells were installed and operated in subsequent
years. In 1992, a catalytic oxidizer unit was installed to control volatile organic compound (VOC)
emissions. In 1997, an air sparge (AS) system was installed along with twenty-five (25) AS wells and
twenty-two (22) groundwater monitoring wells. The AS and SVE systems were turned off in 2000. The
P&T system begin seasonal operation (March-November) in 2001 and then reverted back to year-round
operation in 2012. A vapor effluent carbon vessel was added to the P&T system in 2011. In September
2018, the P&T system was shutdown to monitor groundwater conditions and evaluate alternative remedial
options for the Site. The P&T system, including all associated wells, was removed in 2020. Subsequently
in 2020, construction for a new AS/SVE system was substantially completed at the Site in accordance
with the NCDEQ approved CAP Mod; the SVE system was started in May 2021 and the AS system was
started in June 2021. Currently, twenty-nine (29) wells used for monitoring (of which five (5) are historic
AS wells), fifteen (15) new wells used for SVE, and twenty-eight (28) new wells used for AS are present at
the Site. The Site layout is depicted on Figure 2 and the AS/SVE layout is depicted on Figure 3.Well
construction details including date of installation, top-of-casing elevation, total depth, and screen interval
can be found in Table 1.
2.4.4 Site Geology and Hydrogeology
Soil at the Site is classified as the Madison Series per the Guilford County Geographical Information
System (GIS) website. During previous investigations, soil encountered at the Site was predominantly
classified as reddish-brown silty clay. Soil deeper than approximately fifteen (15) feet below ground
surface (bgs) was described as saprolite.
The Site is located in the Piedmont physiographic province that is characterized by moderately level
interstream areas separated by broad valleys. Bedrock at the Site is mapped within the Charlotte and
Milton Belts. Bedrock is described as intrusive granitic rock (Lilesville Granite) of the Pennsylvanian-
Permian age, characterized as megacrystic to equigranular. During previous investigations, bedrock was
encountered at the Site between 55-70 feet bgs.
In December 2020, during the installation of deep monitoring well (DW-1) completed to 112 feet bgs, the
change from saprolite to highly weathered bedrock occurred between 61-65 feet bgs and from highly
weathered bedrock to partially weathered bedrock between 65-80 feet bgs. Competent bedrock was
encountered at 80 feet bgs and was able to be cored. The bedrock was characterized as diorite to
granodiorite and diabase. From the twenty-five (25) feet of cored rock, the recovery ranged from 84-100%
and the rock quality designation ranged from 82-100%. Four (4) high angle fractures were observed in the
cores collected.
Based on historical data, the groundwater table at the Site, under static conditions, typically ranges from
29-51 feet bgs and groundwater typically flows to the northwest.

3. System Operation
The SVE system was started on May 6, 2021. The AS wells were brought online between June 2, 2021,
and November 18, 2021.
From June 27, 2022 to December 29, 2022, the SVE system runtime was approximately 96.0%, and the
AS system runtime was approximately 91.4%. System downtime time can be attributed to miscellaneous
alarms and a few electrical module failures. Summaries of AS / SVE system operational data are
presented in Tables 2A and 2B, respectively. The tables present system run times (based on air
compressor and blower run hours) and descriptions of any significant activities or issues encountered
during each O&M event.
Since SVE system startup, influent and effluent soil vapor concentrations were monitored and sampled on
a monthly basis. Real-time measurements were collected with a photoionization detector (PID). Samples
were collected in tedlar bags provided by the laboratory and shipped under chain of custody to SGS
North America Inc. (SGS) in Houston, Texas. The samples were analyzed for total petroleum
hydrocarbons (TPH), benzene, toluene, ethylbenzene, total xylenes (BTEX), and methyl tert-butyl ether
(MTBE) by United States Environmental Protection Agency (USEPA) Method TO-15. Analytical results
and calculated volume/mass removed are presented in Table 3. The laboratory reports are included as
Appendix A.
During the reporting period, approximately 3,432 pounds of TPH were removed by the SVE system.
Cumulatively, the system has removed approximately 15,345 pounds of TPH since startup in May 2021.
Periodically, condensate from SVE wells and conveyance lines will accumulate in a sufficient amount
requiring discharge to the sanitary sewer. Prior to discharge, water sampling must be conducted to meet
the requirements set forth in the Special Discharge Permit # S2011 for the site. Monthly results were
reported to the city of Greensboro on a quarterly basis.
During the reporting period, one sample event (December) was needed. Analytical results complied with
limits outlined in Permit # S2011.

4. Groundwater and LNAPL Monitoring Procedures
4.1 Pressure Transducers
AECOM installed In-Situ Level TROLL 500 Data Loggers (transducers) in wells AS1, 2W11, 2W13, and
2W19 prior to shutting down the P&T system in 2018. Since installation, the transducers have
continuously logged groundwater elevations until August 11, 2020, when the transducers were removed
prior to groundwater sampling. In anticipation of system startup, the transducers were re-installed on May
21, 2021, and have been operational since that time, except between May 14, 2022 (June 3, 2022, solely
for 2W11) through September 12, 2022. Upon initial installation an auto-programming feature caused the
pressure transducers to shut off around the May-June 2022; this issue wasn’t discovered until the
transducers were downloaded in September 2022; at which time the issue was corrected. Groundwater
elevation data from the transducers was frequently downloaded and reviewed. The goals were to
continuously monitor groundwater elevations to determine the impact of AS/SVE system on the
groundwater table, to understand seasonal fluctuation, and to assess the impact of precipitation on the
groundwater table.
Wells AS1, 2W11, and 2W13 were selected because of their location along the plume centerline.
Monitoring well 2W19, was selected to establish a background groundwater elevation. Precipitation data
was collected from the USGS website from the Horsepen Creek Station which is located approximately
0.8 miles southwest of the Site.
4.2 Groundwater and LNAPL Gauging
A comprehensive gauging event was conducted prior to the groundwater sampling event in October 2022.
Throughout the reporting period, Site monitoring wells near the source area (2W6, 2W25, 2W26, and
2W27) were periodically gauged for the presence of LNAPL.
Prior to gauging, wells were opened and allowed sufficient time to equilibrate to atmospheric conditions.
Subsequently, depth-to-groundwater and depth-to-LNAPL measurements were collected from Site wells
using an oil-water interface probe.
4.3 Groundwater Sampling
Groundwater sampling activities were completed on October 18-19, 2022, in general accordance with the
CAP Mod. Samples were collected from the following wells: 2W1, 2W3, 2W4, 2W6, 2W7, 2W9, 2W10,
2W11, 2W13, 2W14, 2W17, 2W18, 2W22, 2W23, 2W25, 2W26, 2W27, 2W28, 2W29, DW1, AS1, AS4,
AS9, AS10, and AS13. A sample was not collected from AS4 during the October event because an
insufficient amount of groundwater was recoverable for a representative sample.
Wells were purged using new bottom-loading disposable polyethylene bailers. Purging continued until a
minimum of three (3) well volumes were extracted, or until the well was purged dry. If a well was purged
dry, adequate time was allowed for the groundwater to recover prior to collecting a sample. Each well was
subsequently sampled via the same bailer used for purging.
Samples were collected into laboratory-supplied containers, labeled, and promptly placed on ice in a
cooler with a temperature and trip blank. Groundwater samples were shipped under chain of custody via
overnight delivery to SGS North America, Inc. in Scott, Louisiana for analysis of BTEX, and methyl tert-
butyl ether (MTBE) by USEPA Method 8260D.

5. Groundwater Results
5.1 Groundwater and LNAPL Elevation
For the October 2022 event, the following observations were made:
The overall groundwater flow beneath the Site is generally to the northwest with an approximate
groundwater gradient of 0.018, both of which are consistent with historical interpretations.
Groundwater elevations for the October 2022 groundwater sampling event are shown in Table 4.
Historical groundwater elevations are also shown in Table 4. A groundwater contour map was created for
the October 2022 groundwater sampling event and is presented on Figure 4. LNAPL gauging data,
collected approximately on a monthly basis from the second half of 2022 can be found in Table 5. LNAPL
was not detected throughout the reporting period, thus no passive or active removal efforts were
completed.
Transducers will remain in select Site monitoring wells during 2023 to draw better conclusions about the
groundwater table at the Site. Precipitation will also continue to be monitored and recorded in 2023.
5.2 Groundwater Analytical
Field measurement data were collected ex-situ after sampling via a calibrated Horiba U-52 water quality
meter, and included temperature, pH, dissolved oxygen, oxidation reduction potential, and specific
conductance. Field measurement data for the October 2022 groundwater sampling event are summarized
in Table 6.
Analytical results are presented in Table 7, along with the historical data. In October 2022:
 Monitoring wells 2W4, 2W6, 2W7, 2W25, 2W27, 2W29, AS1, and AS10 exceeded the NC 2L
Standard for benzene.
 Monitoring wells 2W6 and 2W27 exceeded the applicable NC 2L Standards for toluene,
ethylbenzene, and xylenes.
 Monitoring well 2W4, 2W27, 2W29, AS1, and AS10 exceeded the NC 2L Standard for MTBE.
Generally, over the period of record, well concentrations exhibit a decreasing trend or remain stable.
However, concentrations have increased in northern monitoring wells 2W4, 2W7, and 2W23 over the last
several sampling events. For that reason, AECOM is proposing to install two (2) additional monitoring
wells (2W30 and 2W31) along the northern property line prior to the April 2023 sampling event to better
evaluate these conditions. See Figure 2 for the proposed monitoring well locations.
Concentrations in deep well, DW-1, were below laboratory detection limits during the reporting period
suggesting that groundwater impacts are limited to the surficial aquifer at the Site.
Groundwater laboratory analytical results and exceedances of 2L standards for the October 2022
sampling event are shown on Figures 5A, 5B, 5C, 5D,and 5E, respectively, for each of the following
constituents of concern: benzene, toluene, ethylbenzene, xylenes, and MTBE. A copy of the laboratory
report is included as Appendix B.

February 2023 AECOM6-1
6. Soil Vapor Monitoring
6.1 Soil Vapor Sampling
AECOM performed soil vapor sampling events at the Site on August 17, 2022, and November 17, 2022.
Soil vapor samples were collected into laboratory provided 6-liter stainless steel summa canisters.
Sample duration for each soil vapor point was approximately 30 minutes. Prior to sampling, each soil
vapor point was subjected to a helium leak test to confirm that a proper seal was in place. Soil vapor
samples were shipped via overnight delivery under chain of custody to Eurofins TestAmerica, a North
Carolina certified laboratory, in Knoxville, Tennessee for analysis of BTEX, MTBE, naphthalene, and 2-
methylnaphthalene by USEPA Method TO-15 low-level.
6.2 Analytical Results
During the August 2022 sampling event, toluene concentrations in all soil vapor points were detected
above the laboratory detection limit. No other results were reported above the laboratory detection limit
during the reporting period. The results from this reporting period as well as historical results are
presented in Table 8. Copies of the laboratory reports are included as Appendix C. Soil vapor locations
can be found on Figure 2.
2022 Semiannual Report
February 2023 AECOM7-1
7. Quality Control Measures
AECOM did not validate analytical results associated with the monthly SVE air sampling events nor, the
August or November 2022 soil vapor sampling events. AECOM validated analytical results associated
with the October 2022 groundwater monitoring event at the Site. The data review process was modeled
after the USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic
Methods Data Review (EPA, November 2020) with changes and allowances made to conform to
analytical methodology. Qualitative and quantitative limitations associated with the analytical results were
determined based on the results of specific quality control criteria. Accuracy was determined from the
review of spike recoveries. Precision was based on the evaluation of laboratory duplicate
results. Analytical data representativeness and comparability were evaluated from the review of blank
results (laboratory and trip blanks), and sample preservation, storage, and holding time
compliance. Sensitivity was evaluated by comparing reported detection limits to Site-specific reporting
limit objectives. The completeness check of the laboratory deliverable verified that results for all target
analytes were reported by the laboratory. Sample results have been qualified based on the results of the
data review. Samples 2W6 and 2W29 were qualified for holding time compliance. Samples 2W6, 2W9,
2W13, and DW-1 were qualified for surrogate recoveries. All sample concentrations that are less than the
reporting limit, but greater than the method detection limit are estimated. Qualified data are valid and
usable for their intended purpose. Data points were not rejected. In performing the data validation,
AECOM assumed that the data reported by the laboratory are complete, compliant, and an accurate
representation of the raw data. Criteria for acceptability of data were based upon available Site
information, analytical method requirements, guidance documents, and professional judgment.
The oil-water interface probes and the water quality multi-meters were decontaminated with a Liquinox™
and de-ionized water solution prior to use in each well. The water quality meter was calibrated in the field
per the manufacturers’ instructions. Site personnel wore new nitrile gloves that were changed between
each well during sample collection.

February 2023 AECOM8-1
8. Summary
Based on the data obtained from Site investigation activities, the following conclusions are presented:
1. From June 27, 2022 to December 29, 2022, the SVE system runtime was 96.0%, and the
AS system runtime was approximately 91.4%. System downtime can be attributed to
miscellaneous alarms and a few electrical module failures. Routine O&M will continue on a
bi-weekly basis, or as needed. The AS/SVE systems will be continuously monitored,
reviewed, and adjusted in order to maximize performance. The SVE system removed
approximately 3,432 pounds of TPH throughout the reporting period. Additionally, the
catalytic oxidizer reduced effluent TPH concentrations by approximately 96.3%.
2. Continue to record groundwater elevations within the transducer wells, manually gauging
during groundwater sampling events, and periodically gauging for LNAPL in select wells.
Based on Site data, transducers may be relocated to other monitoring wells. Precipitation at
the Site will also continue to be recorded. The purpose of continuing these efforts is to gain
a better understanding of seasonal changes, the relationship between precipitation and the
groundwater table, and any effects attributed to the AS system.
3. For the October 2022 event, groundwater flow direction onsite is toward the north and west
with an approximate horizontal gradient of 0.018 feet/foot, consistent with historical
interpretations.
4. Groundwater analytical data indicated that several wells exceeded applicable 2L standards
for one of more sampled constituents during the October 2022 monitoring event. However,
monitoring well concentrations exhibit a decreasing trend or remain stable over the period
of record. Concentrations in deep well, DW-1, were below laboratory detection limits during
the reporting period. Groundwater sampling will continue in 2023 on a semiannual basis
with the next event occurring in April 2023, as outlined in the CAP Mod. AECOM requests
that the following wells be removed from the sampling plan: 2W9, 2W10, 2W17, 2W26,
AS4, and AS13. As stated in the CAP Mod, wells will be removed from the sampling plan if
they exhibit three (3) consecutive events below applicable 2L groundwater Standards, the
wells proposed for removal meet that criteria. Proposed new monitoring wells 2W30 and
2W31 will be added to the sampling plan to better monitor groundwater conditions in the
northern area of the site and 2W6 will be added to monitoring the interior of the
groundwater plume, near the source area.
5. Concentrations have increased in northern monitoring wells 2W4, 2W7, and 2W23 over the
last several sampling events. Upon approval from NCDEQ, two (2) additional monitoring
wells (2W30 and 2W31) will be installed along the northern property line prior to the April
2023 sampling event to better evaluate these conditions.
6. During the August 2022 sampling event, toluene concentrations in all soil vapor points were
detected above the laboratory detection limit. No other results were reported above the
laboratory detection limit during the reporting period. Soil vapor sampling will continue in
2023 on a quarterly basis with the next event occurring in February 2023.
The next report will be due in August 2023 (semiannually) unless otherwise stated by NCDEQ. The report
will include all activities performed at the Site from January through June 2023.

2 Samples were collected on 10/18/2022 and received intact at SGS North America Inc (SGS) on 10/19/2022 and properly
preserved in 1 cooler at 22 Deg C. The samples received an SGS job number of TD83669. A listing of the Laboratory Sample ID,
Client Sample ID and dates of collection are presented in the Results Summary Section of this report.
The canisters used to collect samples for TO-15 analysis were either individually or batch certified as clean to a level of 0.2 ppbv,
with the exception of Acetone, Ethanol and Isopropanol which are certified to 1.0 ppbv. Methylene Chloride is certified to 0.4
ppbv. Any sample analyte value below certified ppbv value and above the MDL may be from a canister artifact, but there is
currently no B-flag type mechanism to indicate this possibility or that a hit above the MDL and below 0.2 ppbv had been found.
Except as noted below, all method specified calibrations and quality control performance criteria were met for this job. For more
information, please refer to QC summary pages.

Receipt
The samples were received on 8/18/2022 9:15 AM. Unless otherwise noted below, the samples arrived in good condition, and where
required, properly preserved and on ice.
Air - GC/MS VOA
Methods TO 15 LL, TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air" as the blank reagent for
canister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir is used in
place of "zero air" by Eurofins TestAmerica Knoxville.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
