1.0 INTRODUCTION
On behalf of Compass Group, USA (Compass), Antea USA of North Carolina, Inc. (Antea USA of NC) is pleased to 
present this report summarizing recent site activities conducted at the Former Service America Facility (Incident 
No. 16626) located at 2901 North Kerr Avenue in Wilmington, New Hanover County, North Carolina (the Site) 
(Figure 1). The subject site is owned by Compass and was previously operated as a Canteen vending machine 
service facility. 

This report and the activities conducted at the Site were pre‐approved for State Trust Fund reimbursement by 
Ms. Liz Price of the North Carolina Department of Environmental Quality (NCDEQ), Underground Storage Tank 
(UST) Section in correspondence dated May 26, 2022 (Task Authorization No. 21). This report presents a 
summary of the June 2022 groundwater sampling event, field activities and procedures, including conclusions 
and recommendations based on the data collected. 
2.0 ACTIVITIES PERFORMED DURING THIS PERIOD
The following tasks were completed during this reporting period: 
 On June 2, 2022, a post‐PetroFix® groundwater monitoring event was completed with samples 
collected from monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18. 
o During the June 2022 sampling event, samples were collected for laboratory analysis of VOCs, 
sulfate, MADEP VPH, and MADEP EPH via disposable polyethylene bailers.  

For reference purposes, a Site Location Map, a Site Map, and an Extended Site Map are included as Figures 1, 2, 
and 2A respectively. 
3.0 BACKGROUND
Applied Earth Sciences (AES) conducted a Phase I Environmental Site Assessment (ESA) at the subject site in 
August 1996. The Phase I ESA indicated that two 4,000‐gallon gasoline underground storage tanks (USTs) and 
one 4,000‐gallon diesel fuel UST were excavated and removed from the site in 1985. AES was unable to locate 
reports pertaining to the closure of the three USTs. AES subsequently confirmed the presence of gasoline‐
impacted soil and groundwater in the vicinity of the UST basin during assessment activities conducted at the site 
in August 1996. 

A Comprehensive Site Assessment was conducted at the site by AES in February 1997 and a Corrective Action 
Plan (CAP) was submitted to the NCDEQ in July 1999. The CAP recommended excavation and disposal of 
impacted soil and monitored natural attenuation of the groundwater plume. In July 2000, AES excavated 
approximately 563 tons of apparent petroleum‐impacted soil from the former UST basin and placed 300 pounds 
of Oxygen Release Compound® into the open excavation to enhance aerobic bioremediation of the dissolved 
hydrocarbon plume. 

The NCDEQ, Division of Waste Management (DWM), UST Section issued correspondence to Compass dated 
August 27, 2009, requesting continued semi‐annual groundwater monitoring at the site. In addition, the NCDEQ 
requested that Compass prepare a Remediation Monitoring Report summarizing the field activities and progress 
of the ongoing groundwater natural attenuation at the site.

Antea USA of NC submitted a Proposed New Technology Cleanup Plan (PNTCP) dated September 2, 2011, to the 
NCDEQ, DWM, UST Section. The PNTCP evaluated technologies capable of remediating source area dissolved 
phase contaminants of concern (COCs) based on cost and implementability (the practical technical issues 
involved in the implementation of the alternative). The PNTCP recommended three injection events of EAS™, a 
sulfate amendment to promote anaerobic bioremediation, over an 18‐month period along with continued semi‐
annual groundwater monitoring. The NCDEQ approved the PNTCP on September 27, 2011. The Application for 
Permit to Construct and/or Use a Well(s) for Injection (Application) was approved by the NCDEQ, Division of 
Water Quality (DWQ) Underground Injection Control (UIC) Program on April 19, 2012 (permit WI0800272). 

The three EAS™ injections were conducted in 2012 and 2013 with subsequent groundwater sampling. The 
results were summarized in Remediation Monitoring Reports dated August 27, 2012, January 30, 2013, and July 
10, 2013. To improve the overall effectiveness of biodegradation of the petroleum, Antea USA of NC 
recommended additional injection of magnesium sulfate.  

A Notification of Intent to Construct or Operate Injection Wells (Application) was submitted to the NCDEQ, 
Division of Water Resources (DWR), UIC Program on March 25, 2015 for the injection of Nutrisulfate‐LT™ and 
Versamag® (magnesium hydroxide – pH buffer) amendments. The DWR approved the Application on March 30, 
2015 and issued injection permit WI0800415. The injections were conducted on April 21‐24, 2015, followed by a 
groundwater sampling event in May 2015. The results of the injections and sampling event were summarized in 
the Fourth Post‐Injection Remediation Monitoring Report, dated July 15, 2015. The NCDEQ UIC program 
approved the fifth Nutrisulfate‐LT™ amendment injection event under the previous injection permit 
(WI0800415) in an email dated October 8, 2015. The fifth Nutrisulfate‐LT™ injection was conducted on October 
19‐20, 2015 with a pre‐injection groundwater sampling event conducted on August 26, 2015 and two follow‐up 
groundwater sampling events conducted on November 18, 2015 and January 19, 2016. The injection and 
sampling results were provided in the Fifth Post‐Injection Remediation Monitoring Report dated March 17, 
2016. Following submittal of the Fifth Post‐Injection Remediation Monitoring Report, the NCDEQ requested the 
completion of a 6th Nutrisulfate‐LT™ injection event and semi‐annual groundwater monitoring in a 
correspondence dated April 8, 2016. The sixth Nutrisulfate‐LT™ injection was conducted on July 28‐29, 2016 
with a pre‐injection groundwater sampling event conducted in June 2016 and following the injection in August 
2016. The injection and sampling results were provided in the Sixth Post‐Injection Remediation Monitoring 
Report dated September 30, 2016. 

Following submittal of the 6th Post Injection Remediation Monitoring Report, the NCDEQ requested one year of 
semi‐annual groundwater monitoring in correspondence dated November 10, 2016. The two semi‐annual 
monitoring events were conducted on March 9, 2017 and August 15, 2017. The monitoring results were 
provided in the Seventh Post‐Injection Remediation Monitoring Report dated April 28, 2017 and the Eighth Post‐
Injection Remediation Monitoring Report dated October 17, 2017. Following submittal of the Eighth Post‐
Injection Remediation Monitoring Report, the NCDEQ requested completion of continued semi‐annual 
groundwater monitoring events in correspondence dated November 9, 2017. The Ninth Post‐Injection 
Remediation Monitoring Report dated May 15, 2018 summarizes the groundwater results from January and 
March 2018 monitoring events. The 2019 Annual Groundwater Monitoring Report dated June 7, 2019 
summarized the groundwater results from the October 2018, January 2019 and March 2019 monitoring events. 
The 2020 Annual Groundwater Monitoring Report dated August 21, 2020 summarized the groundwater results 
from the October 2019, January 2020, March 2020, and May 2020 monitoring events. The 2021 Annual

3.1 REGENESIS PETROFIX® REMEDIATION FLUID INJECTION ‐ 2019
REGENESIS PetroFix® Remediation Fluid (PetroFix®) is a remedial technology that is designed to remove 
hydrocarbons from the dissolved phase through absorption by activated carbon particles while also stimulating 
hydrocarbon biodegradation through the addition of electron acceptors. The micron sized active carbon fluid is 
applied using direct‐push techniques administered under low pressures to evenly distribute the fluid within the 
target aquifer. 

Between October 29, 2019 and November 6, 2019, Antea USA of NC personnel oversaw the application of 
16,377‐gallons of PetroFix® solution which was injected through 41 temporary injection wells within the vicinity 
of the former USTs by Geologic Exploration, Inc. (Geologic Exploration). Each point received approximately 
398.5‐gallons of injectate volume consisting of nine gallons of PetroFix®, 341‐gallons of water, and 4.3‐pounds of 
biostimulating electron acceptors (i.e., nitrate and sulfate). Figures 2 and 2A show the location and layout of the 
PetroFix® injection temporary well locations. Additional details of the injection were included in the 2020 Annual 
Groundwater Monitoring Report dated August 21, 2020. 
4.0 FIELD ACTIVITIES
4.1 GROUNDWATER MONITORING
One groundwater monitoring event was conducted on June 2, 2022. Following the October 2020 groundwater 
sampling event, WellBooms® were placed in MW‐02, MW‐15, MW‐16, and MW‐18 on February 4, 2021 to 
facilitate biodegradation. The WellBooms® still remain in the abovementioned monitoring wells. 
4.1.1 JUNE 2, 2022 GROUNDWATER MONITORING EVENT
The depth to groundwater was measured in MW‐02, MW‐15, MW‐16, and MW‐18 using an electronic water 
level probe, which was decontaminated prior to each measurement. The monitoring wells were purged of three 
well volumes and samples were collected using disposable polyethylene bailers in general accordance with EPA 
LSASD procedures and the UST Section Guidelines for Sampling. Purge water was placed on the ground in the 
vicinity of each well. New nitrile gloves were worn during sampling of each well to minimize the potential for 
cross‐contamination during the sampling process. Field measurements of pH, specific conductivity, dissolved 
oxygen, oxidation reduction potential, and temperature were collected from the groundwater samples after 
each purged well volume. Samples were collected after three well volumes had been purged. Groundwater 
sampling records summarizing the field measurements are included in Appendix A.  

Groundwater samples were collected into laboratory‐supplied containers, placed into an ice‐filled cooler, and 
transported under chain‐of‐custody to Waypoint in Charlotte, North Carolina.  

Antea USA of NC collected groundwater samples from monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18 to 
monitor remedial progress following the PetroFix® injection. Samples collected via the disposable polyethylene 
bailers were analyzed for:

 Sulfate by EPA Method 9056A 
 MADEP methods for VPH and EPH 
5.0 GROUNDWATER FLOW
Groundwater flow direction in the surficial aquifer was evaluated by development of a groundwater 
potentiometric map (Figure 3) based on water table elevation data obtained from the monitoring wells on June 
2, 2022 (Table 1). Interpretation of the groundwater potentiometric map suggests that the shallow water table 
across the Site flows generally toward the southwest with a hydraulic gradient of approximately 0.02 feet per 
foot (ft./ft.) as interpreted between potentiometric lines. This direction of groundwater flow is similar to flow 
directions inferred from data obtained during previous monitoring events. Additionally, groundwater elevations 
from the Site monitoring wells (Table 1) were consistent with measurements taken last year around the same 
time.  
6.0 LABORATORY ANALYTICAL RESULTS
6.1 GROUNDWATER MONITORING
The laboratory analytical reports and chain‐of‐custody record for the groundwater samples collected June 2, 
2022 are included in Appendix B and the results are summarized in Table 2.  

Monitoring wells MW‐02 and MW‐15 are located in the source area, with MW‐15 being the primary source area 
location. Monitoring well MW‐16 is located upgradient, and MW‐18 is located downgradient from the source 
area. The following compounds exceeded their respective North Carolina groundwater quality standards (2L 
Standards) in groundwater samples collected during the June 2022 monitoring event.

Other target compounds were detected during the three sampling events in monitoring wells MW‐02, MW‐15, 
MW‐16, and MW‐18 at concentrations that exceeded the laboratory method detection limits (MDLs) but were 
below their respective 2L Standards (Table 2). 
6.1.1 BTEX AND BENZENE DISTRIBUTION
Benzene, toluene, ethylbenzene, and total xylenes (collectively referred to as BTEX) have historically been 
detected at concentrations exceeding the laboratory MDLs and/or 2L Standards in the groundwater samples 
collected from monitoring wells MW‐02, MW‐09, MW‐15, MW‐16, and MW‐18. The historical groundwater

analytical data is included in Appendix C. Following the application of the PetroFix®, concentrations of toluene, 
ethylbenzene, and xylenes have been stable or decreasing in monitoring wells MW‐02, MW‐15, MW‐16, and 
MW‐18. This trend suggests that the application of PetroFix® has been successful by removing hydrocarbons 
from the dissolved phase by adsorption while also stimulating hydrocarbon biodegradation from the electron 
acceptors. The concentrations of BTEX compounds have been reduced or remained stable in monitoring wells 
MW‐02, MW‐15, MW‐16, and MW‐18 when compared to the pre‐PetroFix® analytical results. Overall, through 
the June 2022 sampling event, BTEX concentrations showed a slight increasing trend since the pre‐PetroFix® 
monitoring event in monitoring well MW‐02. The BTEX concentrations in source area monitoring well MW‐15 
have decreased to levels below the 2L Standards. The BTEX concentrations in upgradient monitoring well MW‐
16 have decreased to levels below the 2L Standards and remain below laboratory MDLs through June 2022. The 
BTEX concentrations in downgradient monitoring well MW‐18 remain below 2L Standards through June 2022. 

The lateral extent of benzene detected in groundwater on June 2, 2022 is illustrated on Figure 4. Review of 
Figure 4 indicates that groundwater impact appears to be limited to the shallow aquifer in the area immediately 
downgradient of the former UST basin near MW‐15 and MW‐02. Geological cross section locations are identified 
in Figure 2, and geologic cross sections A‐A’ and B‐B’ are included as Figures 5 and 6, respectively. As shown on 
Figures 5 and 6, injection activities targeted the shallow groundwater table within the area of the former tank 
basin which includes the area of the plume exhibiting the highest benzene concentration. Overall, there is a 
notable decrease in plume size and distribution since the PetroFix® application. This is particularly noticeable in 
the area of MW‐15, where benzene concentrations decreased below the 2L Standard, and no plume extent was 
shown on Figure 6.  

Trend graphs for monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18 with post‐PetroFix® data are presented 
on Figures 7 through 10, respectively. Review of the figures indicate that total BTEX concentrations have 
generally decreased in monitoring wells MW‐15, MW‐16, and MW‐18 as compared with the pre‐PetroFix® 
(October 2019) sampling event, however an increase in BTEX is observed in monitoring well MW‐02 since the 
PetroFix® application. The increased concentrations in MW‐02 are likely due to fluctuations in the water table 
where groundwater is contacting remaining contaminant mass in the near surface (i.e., 1‐3‐foot depth) zone, 
and from groundwater movement induced by the injection activities. Monitoring well MW‐02 is located just 
outside the downgradient extent of the application area and did not receive direct contact with the PetroFix®. It 
is not uncommon to see groundwater “mounding” caused by the increased injection pressures while injection is 
ongoing. This “mounding” has the ability to move contaminant mass around in the subsurface as pressures 
equilibrate. Benzene concentrations have, overall, decreased in wells MW‐02, MW‐15, MW‐16, and MW‐18 as 
compared with baseline concentrations established prior to injections (Figure 11). The overall contaminant 
concentrations in MW‐02 are stable to deceasing. The tables below summarize benzene concentrations for 
monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18, pre‐ and post‐Nutrisulfate injection, post‐ORC 
Advanced® Filter Sock installation, and pre‐ and post‐PetroFix® injection.

6.1.2 NAPHTHALENE DISTRIBUTION
Groundwater samples collected at the Site from March 1998 to July 2003 were not analyzed for naphthalene. 
However, the groundwater samples collected at the Site from 2008 through September 2021 were analyzed for 
naphthalene and generally exhibited concentrations that exceeded the laboratory MDLs and/or 2L Standards in 
groundwater samples collected from monitoring wells MW‐02, MW‐09, MW‐15, MW‐16, and MW‐18. The 
lateral extent of naphthalene detected in groundwater on June 2, 2022 is illustrated on Figure 12. Review of 
Figure 12 indicates that groundwater impact appears to be limited to the shallow aquifer within the monitoring 
well network including the area immediately downgradient from the former UST basin, much like that of 
benzene. Since the pre‐PetroFix® monitoring event, naphthalene has increased in concentrations in monitoring 
well MW‐02, decreased or remained stable in MW‐18, decreased in monitoring well MW‐15, and decreased 
below the laboratory reporting limit in MW‐16. The increased concentrations in MW‐02 are likely due to 
groundwater movement (i.e., mounding) induced by the injection activities. The overall contaminant 
concentrations in MW‐02 are stable to deceasing. The tables below summarize naphthalene concentrations for 
monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18, pre‐ and post‐Nutrisulfate injection, post‐ORC 
Advanced® Filter Sock installation, and pre‐ and post‐PetroFix® injection.

6.2 WATER SUPPLY WELL MONITORING
No samples were collected from the on‐site water supply wells (WSW) or the off‐site water supply well (WSW‐1) 
during this reporting period. Power has been disconnected from the on‐site WSW and it was inoperable. 
7.0 NATURAL ATTENUATION EVALUATION
Natural attenuation data including ORP, DO, pH, and sulfate were measured during the June 2022 sampling 
event. These data were evaluated to assess natural attenuation processes. In addition, these data aid in 
assessing the need for future remedial activities. The data collected is included in Table 3 and summarized in the 
following sections. The historical natural attenuation data is included in Appendix D. 
7.1 OXIDATION‐REDUCTION POTENTIAL
The sequential use of a specific electron acceptor is closely related to the ORP of the groundwater. The more 
reducing the groundwater conditions, the greater the depletion of the available electron acceptors (i.e., nitrate, 
manganese, ferric iron, sulfate, and carbon dioxide). A positive ORP typically indicates oxidizing conditions, while 
a negative value indicates chemically reducing conditions. Certain biodegradative processes only occur within a 
specific range of ORP conditions.

Oxidation‐reduction potential measured in groundwater across the Site during the June 2022 sampling event 
indicated ORP values within the core of the shallow groundwater contaminant plume (i.e., MW‐02, MW‐15, 
MW‐16, and MW‐18) exhibited very slightly reducing in MW‐16 [‐1.0 millivolts (mV)] and oxidizing conditions 
ranging from 7 mV (MW‐15) to 58 mV (MW‐18). The ORP values in monitoring wells MW‐15 and MW‐16 have 
historically ranged from ‐201 mV to 113 mV, in monitoring well MW‐02 from ‐207 mV to 80.7 mV, and in 
monitoring well MW‐18 from ‐132 mV to 345.5 mV. The ORP levels fluctuate over time with negative values 
having been dominant in monitoring wells MW‐15 and MW‐16, consistent with reducing groundwater 
conditions.  
7.2 DISSOLVED OXYGEN
Dissolved oxygen concentrations are used to evaluate if aerobic biodegradation may be controlling natural 
attenuation processes. In zones of high BTEX concentration, DO is depleted because the naturally occurring 
microorganisms have utilized the available oxygen during respiration as they biodegrade BTEX and other 
constituents, and any oxygen entering this zone is rapidly depleted. Aerobic biodegradation may be slower and 
incomplete at DO concentrations below 2.0 mg/L and continues at concentrations as low as 0.7 mg/L. Dissolved 
oxygen concentrations below 0.5 mg/L are considered depleted. 

Dissolved oxygen concentrations measured in groundwater across the Site in June 2022 are summarized in Table
4. As summarized, DO readings in shallow groundwater within the contaminant plume (i.e., MW‐02, MW‐15, 
MW‐16, and MW‐18) ranged from 1.61 mg/L to 10.57 mg/L during this event, primarily showing aerobic 
conditions in those monitoring wells. Previously, this Site had been characterized as having depleted or nearly 
depleted DO concentrations (<0.5 mg/L) indicative of an anaerobic environment. However, increased DO 
concentrations during this event indicate favorable aerobic condition in all four of the monitoring wells. 
7.3 PH
Most microbial processes proceed efficiently in a pH range of 6.0 – 8.0 Standard Units (SU). Sulfate reducing 
bacteria grow well at slightly acidic pH, but when sulfate reduction is the dominant process, the groundwater 
tends to become more alkaline because of bicarbonate production. Groundwater pH measurements can be 
another useful parameter in monitoring sulfate reduction, both in terms of identifying where sulfate reduction is 
occurring and where any extreme conditions that might suggest an inhibition of the process. On April 21‐24, 
2015, prior to the fourth sulfate injection, approximately 3,780 pounds of Versamag® (magnesium hydroxide) 
were injected in the source area (i.e., near MW‐02, MW‐15 and MW‐16) at the site to maintain pH levels within 
a reasonable range for beneficial biological activity. 

The pH levels measured in groundwater across the site in June 2022 are presented in Table 4. As summarized, 
pH readings in shallow groundwater in and around the contaminant plume monitoring wells (i.e., MW‐02, MW‐
15, MW‐16, and MW‐18) ranged from 5.47 SU in MW‐02 to 7.37 SU in MW‐16. During all monitoring events, the 
pH values were generally in the favorable range of 6.0 – 8.0 SU where microbial processes can proceed. 
7.4 SULFATE/SULFIDE
Once the available DO, nitrate, manganese, and ferric iron in the groundwater system have been depleted, 
sulfate can be used as an electron acceptor for anaerobic biodegradation of BTEX. Nutrisulfate‐LT™ is a soluble 
electron acceptor solution for the enhanced anaerobic bioremediation of petroleum hydrocarbons. Nutrisulfate‐
LT™ is a sulfate‐enhanced technology that stimulates biodegradation by providing a soluble, readily available 
electron acceptor. In the presence of elevated sulfate, anaerobic groundwater bacteria use the dissolved

petroleum hydrocarbons for carbon and energy, while mineralizing the hydrocarbons to carbon dioxide and 
water. Sulfate is reduced to sulfide during the oxidation of BTEX compounds. As a result, sulfate and sulfide 
concentrations can be used as indicators of biodegradation. The presence of decreased concentrations of sulfate 
and increased concentrations of sulfide in groundwater relative to background concentrations indicate that 
sulfate may be contributing to BTEX biodegradation. It is important to monitor and manage sulfide as 
appropriate during groundwater remediation, so it doesn’t accumulate and create a toxic environment for the 
sulfate reducing bacteria. 

Sulfate concentrations detected in groundwater samples collected at the Site are illustrated on Figure 13. 
Review of Table 4 indicates sulfate concentrations within the contaminant plume have been variable following 
the July 2016 injection. All of the monitoring wells that were sampled (MW‐02, MW‐15, MW‐16, and MW‐18) 
showed generally decreasing sulfate concentrations while DO concentrations have increased.  

Historical sulfide concentrations are provided in Table 4. Previously, minimal levels of sulfide have been noted in 
monitoring wells MW‐02, MW‐15, and MW‐18 following injections and don’t represent levels that would be 
considered toxic to sulfate reducing bacteria. 
8.0 CONCLUSIONS

 Monitoring well MW‐02 is located just outside the downgradient extent of the application area and did 
not receive direct contact with the PetroFix®. Additionally, monitoring well MW‐02 may have been 
affected by groundwater “mounding” during injection activities which may have redistributed 
contaminant mass in the shallow aquifer. It is expected that over time, the contaminant mass 
upgradient from MW‐02 will be adsorbed and remediated by the PetroFix® and concentrations will 
decrease in MW‐02 by biodegradation. 

MW‐18 laboratory results indicate the following:
o June 2016: No compounds exceeded their respective 2L Standards. 
o August 2016: Two compounds, benzene and naphthalene, exceeded their respective 2L Standards. 
o March 2017: Two compounds, benzene and naphthalene, exceeded their respective 2L Standards.

o August 2017: Three compounds, benzene, naphthalene, and VPH/EPH (C09‐C22 aromatic), 
exceeded their respective 2L Standards. 
o January 2018: Two compounds, benzene and naphthalene, exceeded their respective 2L Standards. 
o March 2018: No compounds exceeded their respective 2L Standards.  
o October 2018: Three compounds, benzene, naphthalene, and VPH/EPH (C09‐C22 aromatic), 
exceeded their respective 2L Standards. 
o January 2019: One compound, naphthalene, exceeded its respective 2L Standard. 
o March 2019: One compound, naphthalene, exceeded its respective 2L Standard. 
o October 2019 (Pre‐PetroFix®): Three compounds, naphthalene and VPH/EPH (C05‐C08 aliphatics 
and C09‐C22 aromatics), exceeded their respective 2L Standards. 
o January 2020: No compounds exceeded their respective 2L Standards. 
o March 2020: No compounds exceeded their respective 2L Standards. 
o May 2020: One compound, naphthalene, exceeded its respective 2L Standards. 
o October 2020: One compound, naphthalene, exceeded its respective 2L Standard. 
o March 2021: No compounds exceeded their respective 2L Standards. 
o September 2021: One compound, naphthalene, exceeded its respective 2L Standard. 
o June 2022: Two compounds, naphthalene and VPH/EPH (C09‐C22 aromatic), exceeded their 
respective 2L Standards. 
 The overall decrease in compounds exceeding 2L Standards in monitoring well MW‐18 since the March 
2018 event is indicative of a shrinking plume because of a combination of anaerobic and aerobic 
biodegradation. The increases in EPH and VPH in MW‐18 may be due to the groundwater “mounding” 
during injection activities which may have redistributed contaminant mass in the shallow aquifer. 

General Observations
 The 2019 PetroFix® injection initially showed significant reductions in COC concentrations across the 
Site in monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18. The apparent residual contaminant 
mass observed near MW‐15 in the capillary fringe zone soils (i.e., 1‐3‐foot depth) in 2020, appears to 
have undergone significant bioremediation. Minimal contribution to groundwater concentrations is 
apparent. 
 Based on the June 2022 data, remaining contaminant mass appears to have decreased in the vicinity of 
monitoring well MW‐15. As of June 2022, no compounds remain above their respective 2L Standards 
and ongoing biodegradation is expected to continue in this area. 
 The bulk of the remaining dissolved contaminant mass in groundwater appears to be located in the 
vicinity of monitoring well MW‐02. Bioremediation is expected to continue in the MW‐02 area with 
progress similar to the progress of bioremediation in the MW‐15 area. 
 Minimal contaminant mass remains in the MW‐18 area and ongoing bioremediation is expected to 
continue.

9.0 RECOMMENDATIONS
Based on the above conclusions, Antea USA of NC recommends: 
 Continue semi‐annual groundwater monitoring. Groundwater samples should be collected from 
monitoring wells MW‐02, MW‐15, MW‐16, and MW‐18 and analyzed for VOCs, MADEP VPH/EPH, and 
sulfate.  
 Continue periodic post‐PetroFix® groundwater monitoring of monitoring wells MW‐02, MW‐15, MW‐
16, and MW‐18 for VOCs, MADEP VPH and EPH, and sulfate between semi‐annual monitoring events. 
 Continue annual microbiological assessment updates using QuantArray® analysis. 
 Consider an additional PetroFix® application by direct injection into monitoring wellsMW‐02 and MW‐
18. This would be expected to complete the groundwater remediation and expedite the Incident to 
closure, likely within one year or less. 
 Prepare an Annual Groundwater Monitoring Report summarizing monitoring activities and 
groundwater analytical results.

Dear Rob Thompson:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 6/3/2022 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager
