GROUNDWATER MONITORING REPORT
HAROLD SMITH GROCERY – NCDEQ INCIDENT #12913
2774 UNION RIDGE RD., BURLINGTON, NC 27217

1.0 EXECUTIVE SUMMARY

As requested by TAC Inc., Pyramid Environmental & Engineering, P.C. (Pyramid) has completed
the Groundwater Monitoring Report for the Harold Smith Grocery facility located at 2774 Union
Ridge Rd. in Burlington, Alamance County, NC.

Based on the area reconnaissance and interviews, a total of sixty-two (62) water supply wells
were identified within 1,500 feet of the former UST source area. Currently, no municipal water
supply (city or county) is available for the subject site or surrounding properties. The current
risk classification for the site is High Risk H465R.

The air-sparging (AS) and soil vapor extraction (SVE) treatment system for the Harold Smith
Grocery site began operation in July 1999. The system was operational most of the time during
the July 1999 - May 2011 period. The SVE/AS remediation system significantly remediated both
soil and groundwater. Soil contamination remained in the area of the former pump island
above the Residential MSCCs.

Prior to the May 2011 soil excavation of the former pump island area, the remediation system
was shut down and five air sparging wells were abandoned. Based on certified weight tickets,
483.69 tons of petroleum-contaminated soil were removed from the site. The laboratory results
of the post excavation soil samples collected indicated that all of the accessible contaminated
soil above the residential MSCCs was removed. Contaminated soil remained under the Harold
Smith store building and under the NCDOT roadway.

The original remediation system was upgraded between October 2012 and April 2013.
Additional wells were added to the air sparge segment of the remediation system. Seven
additional air sparge wells were added to surround the groundwater petroleum contaminant
plume. Along with the AS remediation update, the soil vapor extraction system was repaired
after the soil excavation in May 2011. The upgraded remediation system managed to decrease
the groundwater contamination to below the 2L Groundwater Standard in the source area
monitored by monitoring wells MW-1A and MW-15 in September 2016. The remediation
system was shut down on November 28, 2017.

On May 1, 2020, the NCDEQ requested the deactivation of the power account for the Harold
Smith remediation system. Pyramid deactivated the power account on May 5, 2020.

Pyramid has not detected free-phase petroleum product at the site.
Harold Smith Grocery: Incident #12913- Groundwater Monitoring Report 2
Pyramid Project # 2022-024 01/31/2023
A noticeable increase of contaminant concentrations was observed in the monitoring wells in
October 2019. This increase indicates an influx of contaminants back-diffused from the
contaminated soil in the capillary/smear zone beneath the Harold Smith Grocery building and
NCDOT ROW.

The most recent groundwater monitoring event was completed on August 23, 2022. Three (3)
water supply wells and five (5) monitoring wells were sampled during the August 2022
groundwater monitoring event. All samples collected during the groundwater monitoring event
were analyzed for VOCs using Standard Method 6200B.

In August 2022, the influent of the water supply well SW-2765 POE system showed a few
petroleum-related contaminants, of which only 1,2-Dichloroethane (1.49 µg) was detected
above the 2L Groundwater Standard. No contaminants were detected in the supply well POE
system effluent indicating effective treatment of groundwater. Water supply wells SW-2773
and SW-2779 did not show any contaminants above the analytical method reporting limits.

The August 2022 monitoring well analytical results indicate that there are still concentrations of
petroleum hydrocarbons above the 2L Groundwater Standard at the site. It is estimated, based
on average contaminant concentrations in monitoring wells, that the August 2022 groundwater
contaminant mass is 200.72% higher than the November 2016 groundwater contaminant mass.
This increase of contaminant concentrations is most likely due to the influx of the contaminants
back diffused from the area beneath the Harold Smith Grocery building and NCDOT ROW.

Monitoring well MW-1A located in the source area exhibited decrease of the BTEX
concentrations between March 2021 and August 2022. However, the BTEX concentrations have
overall increased more than two orders of magnitude since November 2016. Contaminant
concentrations in the sampled monitoring wells located outside the source area have generally
stayed the same since November 2016.

Monitored Natural Attenuation (MNA) is one of several remedial strategies that could be used
to address the back-diffusion issue at the Harold Smith Grocery site. MNA will be considered a
viable approach if the future groundwater assessment results show that the groundwater
contaminant attenuation rate is equal or higher of the contaminant migration rate.

Pyramid recommends the following:
• Continued semiannual groundwater monitoring at the site. The next groundwater
monitoring event, which should include all monitoring wells and three closest water supply
wells, is planned for March/April 2023. Sampling of all monitoring wells, which was the last
time completed in September 2016, will provide a more detailed picture of the current
groundwater plume at the site. Only three source area monitoring wells and two
downgradient monitoring wells have been sampled since September 2016.
• Soil assessment underneath the Harold Smith Grocery building and in the NCDOT right-of-
way area using angled soil borings. The soil assessment results will assist in finding an
effective and economically feasible remedial approach for the site.

The previous table lists information that pertains to the underground storage tank (UST)
systems at the site. In August 1994, four (4) USTs were removed, and the closure data was
accepted by the DEQ.

3.2 Risk Characterization
The site is in a rural area where no municipal water is available in the area and supply wells are
the only source of potable water. The Harold Smith Grocery groundwater incident should be
classified as “high-risk” since sixty-two (62) active water supply wells are located within 1,500
feet of the source area. The current risk classification for the site is High Risk H465R.

3.2.1 Water Supply Wells
In October 2013, Pyramid completed a receptor survey update. Eight (8) water supply wells
were observed within 500 feet of the source area and fifty-four (54) water supply wells were
observed between 500 feet and 1,500 feet. The subject property contains a water supply well.

A summary of the properties within 1,500 feet is presented as Table 2. Maps of surrounding
properties and water supply wells located within 1,500 feet radius from the source area are
shown in Figures 3a and 3b.

Pyramid Project # 2022-024 01/31/2023
3.2.2 Public Water Supplies
The subject site and all surrounding properties are connected to water supply wells. No
municipal water supply (city or county) is available to the subject site or surrounding properties
at this time. Pyramid had a community meeting to see if the people within 500 feet of the site
would consider a community well project. The community well project was rejected by the
community.

3.2.3 Surface Water
In general, both surface and groundwater flow directions are controlled by topographic
contours of land forms in the Piedmont, with flow occurring perpendicular to the contours from
high to low elevations. Surface water from the subject property flows to the southeast
approximately 600 feet to an unnamed intermittent stream. The location of the site relative to
the intermittent stream is shown in Figure 1.

3.2.4 Wellhead Protection Areas
There are no designated wellhead protection areas within a 1,500-foot radius of the site.

3.2.5 Deep Aquifers in the Coastal Plain Physiographic Region
This section is not applicable to this site.

3.2.6 Subsurface Structures
There are no utilities that are acting to enhance the migration of the contaminant plume. There
is shallow bedrock at the site which may allow accelerated groundwater migration in the upper
fractured bedrock zone between 30 and 40 feet BLS.

3.2.7 Land Use
The subject site was zoned for commercial use and was occupied by the former Harold Smith
Grocery and country gasoline station. The surrounding land use is a mixture of predominantly
residential, some commercial, and agricultural use.

3.3 Site Geology and Hydrogeology

Pyramid’s review of the 1985 Geologic Map of North Carolina yielded information concerning
local geology and hydrogeology of the Piedmont Physiographic Province. The bedrock in the
vicinity of the site has been mapped as felsic intrusive complex, consisting of white to gray,
course to fine grained, massive to foliated felsic intrusive rocks of varying assemblages. Bedrock
was encountered on the site in the vicinity of MW-6 at a depth of about 25 feet BLS.

In general, both surface and groundwater flow directions are controlled by topographic
contours of land forms in the Piedmont, with flow occurring perpendicular to the contours from
high to low elevations. Surface water from the subject property flows to the southeast
approximately 600 feet to an unnamed intermittent stream. The location of the site relative to
the intermittent stream is shown in Figure 1.

Pyramid Project # 2022-024 01/31/2023

The Soil Survey of Alamance County has mapped the area of the subject property as Helena
sandy loam, eroded gently sloping phase. This soil has a permeable surface layer, 25-75% of
which has been eroded away, and a slowly permeable subsoil. Observations from soil borings
at the site indicate a layer of gray, yellowish-brown, or reddish-brown sandy clay or sandy
loam, grading to felsic saprolite. The analytical results of the soil sampling completed in May
2009 were used to complete the soil cross sections presented in Appendix A.

The groundwater flow and hydraulic conductivity data are summarized below:
• Depth to the static groundwater table ranged between 11.92 and 15.22 feet BLS in
October 2017. The substantial increase of the groundwater elevation (more than 6 feet
on average) was observed between groundwater monitoring events completed in
November 2018 and May 2019. Depth to static groundwater table ranged between 4.31
and 6.04 feet BLS in May 2019. During the most recent groundwater monitoring event
completed in February 2020, depth to static groundwater table ranged between 8.52
and 10.17 feet BLS.
• The depth to the upper weathered bedrock surface is approximately 25 feet BLS.
• The average groundwater gradient was 0.013 feet/feet toward the southeast in October
2017. The average groundwater gradient decreased to only 0.004 feet/feet in May 2019.

The groundwater flow velocity for the soil/saprolite zone was estimated to be 0.4 - 1.3 ft/yr.
The actual groundwater flow velocity may be more or less than the calculated value depending
on natural fractures, influences of localized pumping or water recharge, and manmade
features. The groundwater seepage velocity will not coincide with the rate of dissolved
petroleum hydrocarbon migration because of adsorption, dilution, dispersion, diffusion,
retardation, and biodegradation. The very low flow rate suggests isolated porosity (not
interconnected as with sand) in the soil which tends to retain petroleum hydrocarbon
concentrations and slowly release them.

3.4 CAP Implementation and Remediation System Performance

The air-sparging (AS) and soil vapor extraction (SVE) treatment system for the Harold Smith
Grocery site began operation in July 1999. The system was operational most of the time during
the July 1999 - May 2011 period. The SVE/AS remediation system significantly remediated both
soil and groundwater. Soil contamination remained in the area of the former pump island
above the residential MSCCs.

Prior to the May 2011 soil excavation of the former pump island area, the remediation system
was shut down and five air sparging wells were abandoned. Based on certified weight tickets,
483.69 tons of petroleum-contaminated soil were removed from the site. The laboratory results
of the post excavation soil samples collected indicated that all of the accessible contaminated
soils above the Residential MSCCs were removed. Contaminated soil remained under the
Harold Smith store building and in the NCDOT right-of-way (ROW).

Pyramid Project # 2022-024 01/31/2023

In planning for the soil excavation project in 2011, Pyramid recommended that the NCDEQ
approve the placement of oxygen-release compounds in the excavation to help clean up the
site. Placement of these chemical oxidants had been approved and used on several State lead
projects in 2009 and 2010. Since the cleanup standard for the Harold Smith site is the NCAC 2L
Standards, a remedial process that can help reach regulatory closure more quickly should be
considered by the NCDEQ. Pyramid’s request was not approved for Trust Fund reimbursement,
and no oxygen-release compounds were used in the excavation. In the future, the Trust Fund
should consider adding the use of oxygen-release compounds while excavations are open to
help site remediation.

The original remediation system was upgraded between October 2012 and April 2013.
Additional wells were added to the air sparge segment of the remediation system. Seven
additional air sparge wells were added to surround the groundwater petroleum contaminant
plume. Along with the AS remediation update, the soil vapor extraction system was repaired
after the soil excavation in May 2011. The upgraded remediation system layout is shown in
Figure 4. The upgraded remediation system managed to decrease the groundwater
contamination to below the 2L Groundwater Standard in the source area monitored by
monitoring wells MW-1A and MW-15 in September 2016. The remediation system was shut
down on November 28, 2017.

A noticeable increase of contaminant concentrations has been observed in the source
monitoring wells since November 2016. This increase indicates an influx of contaminants back-
diffused from the contaminated soil in the capillary/smear zone beneath the Harold Smith
Grocery building and the NCDOT ROW. The most effective solution for the back-diffusion
contaminants observed in the past few years is being evaluated.

On May 1, 2020, the NCDEQ requested the deactivation of the power account for the Harold
Smith remediation system. Pyramid deactivated the power account on May 5, 2020.

4.0 SITE ASSESSMENT INFORMATION

4.1 Extent of Soil Contamination The two most recent soil sampling events were completed in March 2009 and May 2011. Six (6)
soil borings (SB1 through SB3 and MW-13 through MW-15) were installed in the area of the
former pump island/piping and twelve (12) soil samples were collected for laboratory analysis
in March 2009. The locations of the soil borings are shown in Figure A-1 included in Appendix
A. The March 2009 soil analytical results identified soil concentration above the Residential
MSCCs in the former pump island area. The March 2009 soil sample analytical results are
summarized in Table A-2 included in Appendix A.

Harold Smith Grocery: Incident #12913- Groundwater Monitoring Report 8
Pyramid Project # 2022-024 01/31/2023
The excavation of the contaminated soil in the former pump island area was completed in May
2011. Based on certified weight tickets, 483.69 tons of petroleum-contaminated soil were
removed from the site. The laboratory results of the post excavation soil samples collected
indicated that all of the accessible contaminated soils above the Residential MSCCs were
removed. A summary of the post-excavation soil sample results is shown in Table A-3 included
in Appendix A. An approximate boundary of the May 2011 soil excavation as well as the
horizontal and vertical extent of the March 2009 soil concentrations are illustrated in the soil
concentration cross sections A-A’ and B-B’ (Figures A-4 and A-5) included in Appendix A.

The Harold Smith Grocery soil contaminant mass baseline of 113.42 kilograms (~250 lbs.) was
established based on the average soil contaminant concentrations detected during the May
2011 post-excavation soil sampling activities and estimated volume of contaminated soil. The
extent of contaminated soil in the NCDOT ROW cannot be directly assessed. The soil
contaminant mass baseline calculation is included in Appendix A.

4.2 Extent of Groundwater Contamination The most recent groundwater monitoring event was completed on August 23, 2022. Three (3)
water supply wells and five (5) monitoring wells were sampled during the August 2022
groundwater monitoring event. All samples collected during the groundwater monitoring event
were analyzed for VOCs using Standard Method 6200B.

The August 2022 monitoring well analytical results indicate that there are still concentrations of
petroleum hydrocarbons above the 2L Groundwater Standard at the site. The estimated
groundwater mass contamination was calculated using the equation provided in the
“Quantitative Environmental Indicators of Contamination” paper published by the EPA in
November 2011. The estimated groundwater mass calculation spreadsheet is included in
Appendix C. It is estimated, based on average contaminant concentrations in monitoring wells,
that the August 2022 groundwater contaminant mass is 200.72% higher than the November
2016 groundwater contaminant mass. This increase of contaminant concentrations is most
likely due to the influx of the contaminants back diffused from the area beneath the Harold
Smith Grocery building and NCDOT ROW. Graph 3 shows estimated groundwater contaminant
mass vs. time.

Monitoring well MW-1A located in the source area exhibited decrease of the BTEX
concentrations between March 2021 and August 2022. However, the BTEX concentrations have
Harold Smith Grocery: Incident #12913- Groundwater Monitoring Report 11
Pyramid Project # 2022-024 01/31/2023
overall increased more than two orders of magnitude since November 2016. Contaminant
concentrations in the sampled monitoring wells located outside the source area have generally
stayed the same since November 2016.

4.2.4 GROUNDWATER REMEDIATION The air-sparging (AS) and soil vapor extraction (SVE) treatment system for the Harold Smith
Grocery site began operation in July 1999. The system was operational most of the time during
the July 1999 - May 2011 period.

Before of the soil excavation project in 2011, portions of the remediation system were
decommissioned. The soil remediation removed petroleum contaminated soils in the source
area and into the capillary fringe to assist groundwater cleanup over the long term. In 2011
Pyramid recommended the placement of oxygen release compounds in the excavation. The
preapproval request was denied by the Trust Fund Branch.

After the excavations were backfilled, the original remediation system was upgraded between
October 2012 and April 2013. Additional wells were added to the air sparge segment of the
remediation system to surround the groundwater petroleum contaminant plume. Along with
the AS system upgrade, the soil vapor extraction system was repaired. The upgraded
remediation system layout is shown in Figure 4. The upgraded remediation system managed to
decrease the groundwater contamination to below the 2L Groundwater Standard in the source
area monitored by monitoring wells MW-1A and MW-15 in September 2016. The remediation
system was shut down on November 28, 2017.

On May 1, 2020, the NCDEQ requested the deactivation of the power account for the Harold
Smith remediation system. Pyramid deactivated the power account on May 5, 2020.

A noticeable increase of the contaminant concentrations in the source monitoring wells was
observed for the first time in October 2019. The increases point to influxes of contaminants
back-diffused from the contaminated soil in the capillary/smear zone beneath the Harold Smith
Grocery building and the NCDOT ROW. The most effective solution for the back-diffusion
contaminants observed in the past few years is being evaluated.

6.0 MONITORED NATURAL ATTENUATION

Monitored Natural Attenuation (MNA) is one of several remedial strategies that could be used
to address the back-diffusion issue at the Harold Smith Grocery site. MNA will be considered a
viable approach if the future groundwater assessment results show that the groundwater
contaminant attenuation rate is equal or higher of the contaminant migration rate. To acquire
the necessary data for the MNA evaluation, Pyramid recommends continued semiannual
groundwater monitoring at the site.

7.0 CONCLUSIONS AND RECOMMENDATIONS

7.1 Conclusions

• Based on the area reconnaissance and interviews, a total of sixty-two (62) water supply
wells were identified within 1,500 feet of the source area. Currently, no municipal water supply
(city or county) is available for the subject site or surrounding properties. The current risk
classification for the site is High Risk H465R.

• In 2004 Pyramid and the NCDEQ met with the local well users in a community meeting to
discuss municipal and a community well system for the Harold Smith site. The community well
plan was rejected by the residents.

• The air-sparging (AS) and soil vapor extraction (SVE) treatment system for the Harold Smith
Grocery site began operation in July 1999. The system was operational most of the time during
the July 1999 - May 2011 period. The SVE/AS remediation system significantly remediated both
soil and groundwater. Soil contamination remained in the area of the former pump island
above the Residential MSCCs.

• Prior to the May 2011 soil excavation of the former pump island area, the remediation
system was shut down and five air sparging wells were abandoned. Based on certified weight
tickets, 483.69 tons of petroleum-contaminated soil were removed from the site. The
laboratory results of the post-excavation soil samples indicated that all the accessible
contaminated soils above the residential MSCCs were removed. Contaminated soil remained
under the Harold Smith store building and the NCDOT ROW.

• The original remediation system was upgraded between October 2012 and April 2013.
Additional wells were added to the air sparge segment of the remediation system. Seven
additional air sparge wells were added to surround the groundwater petroleum contaminant
plume. Along with the AS remediation update, the soil vapor extraction system was repaired
due to the damage the system sustained during soil excavation in May 2011.

• The upgraded remediation system managed to decrease the groundwater contamination to
below the 2L Groundwater Standard in the source area monitored by monitoring wells MW-1A
and MW-15 in September 2016.

• The remediation system was shut down on November 28, 2017.

• On May 1, 2020, the NCDEQ requested the deactivation of the power account for the
Harold Smith remediation system. Pyramid deactivated the power account on May 5, 2020.

• Pyramid has not detected free-phase petroleum product at the site.

• In August 2022, the influent of the water supply well SW-2765 POE system showed a few
petroleum-related contaminants, of which only 1,2-Dichloroethane (1.49 µg) was detected
above the 2L Groundwater Standard. No contaminants were detected in the supply well POE
system effluent indicating effective treatment of groundwater.

• In August 2022, water supply wells SW-2773 and SW-2779 did not show any contaminants
above the analytical method reporting limits. Water supply well SW-2773, which provides water
to the Lassiter residence, showed 1,2-Dichloroethane concentrations above the 2L
Groundwater Standard before May 2019. TAC, Inc. provides bottled water to the Lassiter
residence.

• The August 2022 monitoring well analytical results indicate that there are still
concentrations of petroleum hydrocarbons above the 2L Groundwater Standard at the site. It is
estimated, based on average contaminant concentrations in monitoring wells, that the August
2022 groundwater contaminant mass is 200.72% higher than the November 2016 groundwater
contaminant mass. This increase of contaminant concentrations is most likely due to the influx
of the contaminants back diffused from the area beneath the Harold Smith Grocery building
and NCDOT ROW.

• Monitoring well MW-1A located in the source area exhibited decrease of the BTEX
concentrations between March 2021 and August 2022. However, the BTEX concentrations have
overall increased more than two orders of magnitude since November 2016. Contaminant
concentrations in the sampled monitoring wells located outside the source area have generally
stayed the same since November 2016.

• Monitored Natural Attenuation (MNA) is one of several remedial strategies that could be
used to address the back-diffusion issue at the Harold Smith site. MNA will be considered a
viable approach if the future groundwater assessment results show that the groundwater
contaminant attenuation rate is equal or higher of the contaminant migration rate.

7 .2 Recommendations Pyramid recommends the following: • • 1 2 3 4 5 6 Continued semiannual groundwater monitoring at the Harold Smith Grocery site. The next groundwater monitoring event, which should include all monitoring wells and three closest water supply wells, is planned for March/April 2023. Sampling of all monitoring wells, which was the last time completed in September 2016, will provide a more detailed picture of the current groundwater plume at the site. Only three source area monitoring wells and two downgradient monitoring wells have been sampled since September 2016. Soil assessment underneath the Harold Smith Grocery building and in the NCDOT right-of-way area using angled soil borings. The soil assessment results will assist in finding an effective and economically feasible remedial approach for the site. 8.0 STATEMENT & CERTIFICATION Enter the date the monitoring report was due. No due date was requested by NCDEQ. Will YES this report be submitted after the established due date? Was any required information from the above template missing from this report? YES If applicable, will any of the proposed attenuation milestones under the schedule approved YES in the Corrective Action Plan not be met? (within a reasonable margin of error) Does any known or suspected source zone soil contamination or free product remain YES outside of the assessed area that could be inhibiting natural attenuation? Has there been an unexpected increase in contaminant mass sufficient to suggest a YES potential new release from a separate onsite or offsite source? Certification: I, Michael G. Jones, P.G., a Licensed Geologist for Pyramid Environmental & Engineering, P.C., do certify that the information contained in this report is correct and accurate to the best of my knowledge.

Lab Report Number: 22-241-0010 Client Project Description: Harold Smith
Dear Mika Trifunovic:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 8/29/2022 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
