Monitoring Report – Colvard Oil Company - Sugar Grove Shell 1 Pyramid Project No.: 2022-225 12/28/2022
MONITORING REPORT
Sugar Grove Shell
Sugar Grove, NC
1.0 EXECUTIVE SUMMARY

As requested by Colvard Oil Company, Pyramid Environmental & Engineering, P.C. (Pyramid)
has completed the Monitoring Report for the Sugar Grove Shell site (NC DEQ #18455) located at
1193 US Hwy 321, Sugar Grove, Watauga County, North Carolina.

Based on the receptor survey update completed by Pyramid in 2015, a total of seventeen (17)
water supply wells were identified within 1000 feet of the source area. All properties within
1,500 feet of the source are supplied by water from private water wells. Municipal water is not
available to the site or surrounding properties.

A Notice of Regulatory Requirements was issued to Colvard Oil in April 1998 requiring
assessment at the Sugar Grove Shell site. From June to September 1998, ten type II monitoring
wells (MW-1 through MW-10) and one type III deep monitoring well (DW-1) were installed on
the Shell site. Soil samples were collected during monitoring well installation and showed
concentrations in excess of the Soil-to-Groundwater (STGW) Maximum Soil Contaminant
Concentrations (MSCCs). The monitoring well analytics showed petroleum detections exceeding
the NCAC 2L Standard, with benzene exceeding the Gross Contaminant Levels (GCLs) in MW-1,
MW-3 and MW-6.

The Soil Corrective Action Plan, dated March 31, 1999, recommended excavation of the
impacted soil in the areas of the former USTs, including the orphaned USTs (which were
reportedly closed in place with sand), and removal of the pump island. On July 19-23, 1999,
1,469 tons of petroleum contaminated soil was removed from the UST basin and pump island.
The soil was excavated to groundwater levels at approximately 12 feet BLS. At the time of
excavation (1999), soils remaining at the site were reported to have petroleum concentrations
below the Soil to Groundwater MSCCs.

Subsequent to the excavation, the soil and groundwater assessment in areas downgradient of
the former UST area showed gasoline free-phase petroleum product was found in the soil and
groundwater.

Between February 2009 and August 2013, Pyramid completed eight (8) MMPE events at the site
to remove free product and reduce dissolved petroleum contamination in the groundwater.
Monitoring Report – Colvard Oil Company - Sugar Grove Shell 2 Pyramid Project No.: 2022-225 12/28/2022

On October 23 and 24, 2019, monitoring wells were gauged and sampled. Free-product was
identified in MW-6 (1.83 feet), MW-10 (2.30 feet), and MW-16 (2.39 feet). These wells were
not sampled during this sampling event. Benzene concentrations were observed in MW-2,
MW-3, MW-4, MW-12, MW-13, and RW-1 above the 2L Standard. No benzene detections were
identified above the GCLs.

As directed by NCDEQ, on October 24, 2019, five (5) supply wells (WW-1, WW-2, WW-3, WW-4,
and WW-6) were sampled for petroleum hydrocarbons using EPA Method 6200B and 504.1 for
EDB. The laboratory results of the samples collected from WW-1, WW-2, WW-3, and WW-6
showed no detection of petroleum hydrocarbons. The laboratory results for supply well WW-4
detected MTBE at an estimated “J” value of 0.45 µg/l above laboratory detection limits, but
below 2L Groundwater Standard.

On September 17 and 18, 2022, monitoring wells were gauged and sampled. Free-product was
identified in MW-6 (0.70 feet), MW-10 (2.20 feet), MW-16 (2.34 feet), and RW-1 (0.05 feet).
These wells were not sampled during this sampling event. Benzene concentrations were
observed in MW-3, MW-12, and MW-13 above the 2L Standard. No benzene detections were
identified above the GCLs.

On September 18, 2022, four (4) supply wells (WW-1, WW-2, WW-3, and WW-6) were sampled
for petroleum hydrocarbons using EPA Method 6200B and 504.1 for EDB. The laboratory
results of the samples collected from WW-1, WW-2, WW-3, and WW-6 showed no detection of
petroleum hydrocarbons.

2.0 INTRODUCTION

Pyramid Environmental & Engineering, P.C. (Pyramid) completed a free-product evaluation,
gauging, and sampling event of the monitoring wells and nearby supply wells for the former
Sugar Grove Shell. Pyramid consulted with the North Carolina Department of Environmental
Quality (DEQ) concerning the scope of work, and the preapproval/task authorization (TA) forms
were sent to the State. The work was approved, and this report presents the details of the
work.

3.0 SITE HISTORY

The Sugar Grove Shell property, located on US Highway 321 in Sugar Grove, Watauga County,
North Carolina, was the site of three 2,000-gallon gasoline underground storage tanks (USTs). A
petroleum release was discovered during environmental assessments at the Cove Creek Exxon,
up-gradient and across US Hwy 321 from the Sugar Grove Shell. Cove Creek Exxon showed free-
product during the 1994 UST removal. Contaminated soil was excavated from the Cove Creek
Exxon tank pit.

A Notice of Regulatory Requirements was issued to Colvard Oil in April 1998 requiring
assessment at the Sugar Grove Shell site. From June to September 1998, ten type II monitoring
wells (MW-1 through MW-10) and one type III deep monitoring well (DW-1) were installed on
the Shell site. Soil samples were collected during monitoring well installation and showed
concentrations in excess of the Soil-to-Groundwater (STGW) Maximum Soil Contaminant
Concentrations (MSCCs). The monitoring well analytics showed petroleum detections exceeding
the NCAC 2L Standard, with benzene exceeding the Gross Contaminant Levels (GCLs) in MW-1,
MW-3 and MW-6. The surrounding properties are all served by private water supply wells. A
Comprehensive Site Assessment (CSA) was submitted to DEQ on September 28, 1998.

The Soil Corrective Action Plan, dated March 31, 1999, recommended excavation of the
impacted soil in the areas of the former USTs, including the orphaned USTs (which were
reportedly closed in place with sand) and the pump island.

On July 19-23, 1999, 1,469 tons of petroleum contaminated soil was removed from the UST
basin and pump island. The soil was excavated to groundwater levels at approximately 12 feet
below land surface (BLS). Monitoring wells MW-1, MW-5 and DW-1 were destroyed during the
excavation. MW-4 was reported to have been destroyed at the time of excavation as well;
however, Pyramid later found MW-4 at the site. At the time of excavation (1998), soils
remaining at the site were reported to have petroleum concentrations below the Soil to
Groundwater MSCCs.

Monitoring Report – Colvard Oil Company - Sugar Grove Shell 7 Pyramid Project No.: 2022-225 12/28/2022
On October 27, 1999, selected monitoring wells and supply wells were sampled. Monitoring
well MW-10 showed free-product and MW-6 and MW-8 showed an increase in benzene, raising
the suspicion that the contaminant plume from the Cove Creek Exxon was migrating onto the
Sugar Grove Shell site. All other concentrations remained stable.

Pyramid called and confirmed that the Cove Creek Exxon is listed as a State Lead Program site
and the site ranking is H315D. The comments in the UST database showed that in October 2007
groundwater sampling of water supply well 4 (WW-4) were below detection.

In 2014, MW-18, MW-20, and MW-21 were destroyed in North Carolina Department of
Transportation (NC DOT) bridge replacement work. Monitoring well MW-18 has consistently
been high in petroleum hydrocarbons, showing a small amount free-product during the last
MMPE event.

On September 23, 2013, Pyramid and Hill Equipment Co. mobilized to Sugar Grove Shell to
perform an MMPE event. Depth to the water table was 12.55 feet in MW-6 and 12.33 feet in
MW-10. Free-phase petroleum product was measured in MW-10 (1.94 feet or 0.31 gallons)
before the MMPE event.

MW-6 and MW-10 were used as the recovery wells for the MMPE event. The PVC stingers were
set at 15 feet deep in MW-6 and 17 feet deep in MW-10 to maximize groundwater recovery.
The MMPE event was terminated at 1:00 pm on September 27, 2013 after 84.5 hours of
operation. A total of 5,308 gallons of water was recovered. This represents an average recovery
rate of 62.82 gallons per hour or 1.05 gallon per minute (gpm). Field parameters collected
during the MMPE event were used to calculate the total amount of hydrocarbons removed as
vapors during the event. The calculated total of hydrocarbons removed was approximately
43.92 pounds for the September 2013 MMPE event which is equal to 7.03 gallons of free-phase
petroleum product as vapors, plus 0.31 gallons of free-product recovered in the tanker, for a
total of 7.34 gallons.

4.0 SOIL ASSESSMENT (2014)

On May 27 and 28, 2014, eighteen (18) soil borings (GP1 through GP18) were installed at,
around, and down-gradient of the former gasoline UST system. The soil borings were installed
using direct push drilling methods and soil samples were collected using 5-foot long 2-inch
diameter macro-core soil sampling tube. Since the depth to the top of the groundwater has
ranged from 8 to 13 feet below land surface (BLS), the soil samples were collected above 14
feet BLS. The locations of the soil borings are shown on Figure 4.
Monitoring Report – Colvard Oil Company - Sugar Grove Shell 8 Pyramid Project No.: 2022-225 12/28/2022

A total of twenty-seven (27) soil samples were collected for laboratory analysis, and the soil
samples were placed in laboratory prepared containers placed on ice, and shipped to Pace
Analytical Laboratories in Huntersville, North Carolina for analysis. The soil samples were
analyzed for volatile organic compounds using EPA Method 8260/5035 and MADEP VPH. The
results from the soil samples are summarized on Table 3.

The laboratory results for soil samples GP1-10-12.5, GP5-10-12, GP9-10-13, GP10-7.5-10, GP10-
10-13, and GP12-11-14 detected petroleum hydrocarbon compounds above soil-to-
groundwater MSCC levels, but below residential MSCC levels. The laboratory results for soil
samples GP1-7.5-10, GP2-7.5-10, GP5-7.5-10, GP7-8-10, GP9-10-13, and GP11-7.5-10 had
laboratory detections of petroleum hydrocarbon compounds above laboratory reporting limits,
but below soil-to-groundwater MSCC levels. The laboratory results for soil sample GP2-5-7,
GP3-12.5-14, GP4-2.5-5, GP4-8-10, GP6-8-10, and GP8-7.5-10 were non-detect. The soil
sampling locations and concentrations relative to the Soil-to-Groundwater (STGW) and
residential Maximum Soil Contaminant Concentrations (MSCCs) are shown on Figure 4. The soil
cross section locations are on Figure 5. The soil cross are shown on Figures 6 and 7. The area
of the core of the petroleum hydrocarbon plume is identified in the soil and groundwater
originating from the former Shell UST area and migrating to the west-northwest.

5.0 RECEPTOR INFORMATION

In October 2015, a receptors survey update was completed for the site. All properties within
1,500 feet of the source are supplied by water from private water wells. Municipal water is not
available to the site or surrounding properties. Water supply well WW-1 was redrilled in 2006
and serves the Townsend residence. The Townsend supply well is located less than 20 feet from
MW-10, which has shown free-phase petroleum product in several gauging events. A summary
of the properties within 1,000 feet with supply well locations is included in Table 2 and shown
on Figure 3.

The post office water supply well is also located within 30 feet of MW-16 which has shown
several feet of free-phase petroleum product. These wells are of great concern, although to
date they have not shown any detection of petroleum hydrocarbons. The petroleum
contaminant concentrations appear to be most concentrated near the water table at 10-15 feet
below land surface (BLS). The supply wells are cased deeper and withdraw water from a deeper
water bearing zone.

Monitoring Report – Colvard Oil Company - Sugar Grove Shell 9 Pyramid Project No.: 2022-225 12/28/2022
In addition, there is an upgradient source of petroleum hydrocarbons; the Cove Creek Exxon
station. This site was reported as a contaminated site in 1994 and has been reported to have
shown free-product in the groundwater when the USTs were removed. The former Exxon UST
area is located directly upgradient of MW-16 which shows the greatest amount of free-product
at this time.

6.0 FREE PRODUCT RECOVERY

On September 23, 2013, Pyramid and Hill Equipment Co. mobilized to Sugar Grove Shell to
perform an MMPE event. Depth to the water table was 12.55 feet in MW-6 and 12.33 feet in
MW-10. Free-phase petroleum product was measured in MW-10 (1.94 feet or 0.31 gallons)
before the MMPE event.

MW-6 and MW-10 were used as the recovery wells for the MMPE event. The PVC stingers were
set at 15 feet deep in MW-6 and 17 feet deep in MW-10 to maximize groundwater recovery.
The MMPE event was terminated at 1:00 pm on September 27, 2013 after 84.5 hours of
operation. A total of 5,308 gallons of water was recovered. This represents an average recovery
rate of 62.82 gallons per hour or 1.05 gallon per minute (gpm). Field parameters collected
during the MMPE event were used to calculate the total amount of hydrocarbons removed as
vapors during the event. The calculated total of hydrocarbons removed was approximately
43.92 pounds for the September 2013 MMPE event which is equal to 7.03 gallons of free-phase
petroleum product as vapors, plus 0.31 gallons of free-product recovered in the tanker, for a
total of 7.34 gallons.

Free-product was identified in MW-6 (0.7 feet), MW-10 (2.20 feet), MW-16 (2.34 feet), and RW-
1 (0.05 feet). These wells were not sampled during this sampling event, but would likely show
elevated concentration of dissolved benzene and BTEX.

7.0 GROUNDWATER MONITORING

7.1 Monitoring Well Sampling

are reported in micrograms per liter (µg/l). Several monitoring wells in the core of the free-
product area were not sampled, and would likely show higher dissolved groundwater
concentrations.

CURRENT MAXIMUM BENZENE (08/18/22): 1,310 µg/l (MW-13)
PREVIOUS MAXIMUM BENZENE (10/23-24/19): 1,300 µg/l (RW-1)
Historic Maximum Benzene (6/26/1998): 17,500 µg/l (MW-1)

CURRENT MAXIMUM BTEX (08/18/22): 15,701 µg/l (MW-13)
PREVIOUS MAXIMUM BTEX (10/23-24/19): 16,888 µg/l (MW-12)
Historic Maximum BTEX (6/26/1998): 51,120 µg/l (MW-1)

CURRENT MAXIMUM MTBE (08/18/22): 0.533 µg/l (MW-12)
PREVIOUS MAXIMUM MTBE (10/23-24/19): Estimated 2.9 µg/l (MW-13)
Historic Maximum MTBE (6/4/1998): 1,040 µg/l (MW-1)

CURRENT MAXIMUM 1,2-DCA (08/18/22): ND µg/l
PREVIOUS MAXIMUM 1,2-DCA (10/23-24/19): 14 µg/l (RW-1)
Historic Maximum 1,2-DCA (6/4/1998): 306 µg/l (MW-1)
Several Wells were not sampled because of FP

CURRENT MAXIMUM EDB (08/18/22): MW-6 not sampled - FP
PREVIOUS MAXIMUM EDB (10/23-24/19): MW-6 not sampled - FP
Historic Maximum EDB (7/30-31/2008): 230 µg/l (MW-6)
Several Wells were not sampled because of FP

Concentrations have generally fluctuated up and down due to groundwater and free product
fluctuations; it is important to note that MW-6 and MW-16 have not been sampled since
September 2010 due to the presence of free-phase petroleum product. These wells have shown
higher dissolved petroleum contaminants and are likely to reflect higher levels when sampled in
the future.

7.4 Summary of Groundwater Analytical Results
The results of the August 17-18, 2022 sampling event showed the groundwater concentrations
to be about the same as the previous sampling event; although there is still free-product in the
core of the plume. The concentrations are discussed in the paragraphs that follow.
Monitoring Report – Colvard Oil Company - Sugar Grove Shell 13 Pyramid Project No.: 2022-225 12/28/2022
Free-Product
Free-product was identified in MW-6 (0.7 feet), MW-10 (2.20 feet), MW-16 (2.34 feet), and RW-
1 (0.05 feet). These wells were not sampled during this sampling event, but would likely show
elevated concentration of dissolved benzene and BTEX.

Benzene Concentrations
Benzene concentrations were observed in MW-3, MW-4, MW-12, MW-13, and RW-1 above the
2L Standard. The benzene concentrations in MW-3 has decreased, and MW-13 has increased
from the previous sampling event. No benzene detections were identified above the Gross
Contaminant Levels (GCLs); however, MW-6, MW-10, MW-16, and RW-1 showed free-phase
(gasoline) petroleum product and were not sampled. The benzene isoconcentration map for
the August 2022 sampling is presented as Figure 9. The groundwater remediation goal remains
1 µg/l for benzene.

Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX)
Concentrations of the compounds benzene, toluene, ethylbenzene, and xylenes (BTEX) were
identified in MW-2, MW-3, MW-4, MW-8, MW-11, MW-12, and MW-13. The remaining wells
were below detection limits in the wells that were sampled in August 2022. The total xylene
isoconcentration map for the August 2022 sampling is presented as Figure 10.

Methyl Tert Butyl Ether (MTBE)
No monitoring wells showed MTBE concentrations above the NCAC 2L Groundwater Standard.
The MTBE concentration map is included in Figure 11.

Ethylene Dibromide (EDB)
No monitoring wells showed EDB concentrations above the NCAC 2L Groundwater Standard;
however, the wells that have shown EDB were not sampled due to the presence of Free-
Product. If sampled in the future, it is expected that EDB will be detected again.

Naphthalene
Concentrations of naphthalene were detected in MW-2, MW-3, MW-4, MW-8, MW-12, and
MW-13. All detected naphthalene concentrations were above the 2L Standard, but no
concentrations of naphthalene exceed GCLs. The naphthalene isoconcentration map is included
as Figure 12.

Monitoring Report – Colvard Oil Company - Sugar Grove Shell 14 Pyramid Project No.: 2022-225 12/28/2022
1,2,4-Trimethylbenzene
Concentrations of 1,2,4-trimethylbenzene were detected in MW-2, MW-3, MW-4, MW-8, MW-
11, MW-12, MW-13, and RW-1. The 1,2,4-trimethylbenzene concentrations were above the 2L
Standard except in MW-3, MW-12, MW-13, and RW-1. The 1,2,4-trimethylbezene
isoconcentration map is included as Figure 13.

Based on the August 2022 monitoring well analytical results, the following statements can be
concluded:

• Free-product and high levels of dissolved petroleum hydrocarbons remain at the
Colvard property and the down-gradient post office property.

• The aerial extent of dissolved hydrocarbons in groundwater was assessed within the
monitoring well network, and appears to be stable within these perimeter wells for the
past 8 years.

• Deeper groundwater monitoring was completed using WW-1, WW-2, WW-3, and WW-6
which showed no petroleum contaminant detections.

• Several downgradient monitoring wells were destroyed by the NCDOT during road
construction activities (MW-18, MW-20 and MW-21).

• The petroleum concentrations in the perimeter wells to the north, south and east of the
former USTs have remained low. Since the site is a high-risk site, continued groundwater
monitoring and remediation is required.

7.5 Supply Well Analytical Results
On August 18, 2022, four supply wells (WW-1, WW-2, WW-3, and WW-6) were sampled for
petroleum hydrocarbons. The supply well samples were collected using new disposable nitrile
gloves after purging the well for 15 to 20 minutes, and were collected in laboratory containers
for analyses using EPA Method 6200B and 504.1 for EDB. The laboratory results of the samples
collected showed no detection of petroleum hydrocarbons in any of the water supply wells
sampled. Copies of the supply wells letters are included in Appendix C.

Monitoring Report – Colvard Oil Company - Sugar Grove Shell 15 Pyramid Project No.: 2022-225 12/28/2022
8.0 MNA & SOURCE DEPLETION

The Sugar Grove Shell site was discussed with the NCDEQ several time and a New Technology
Cleanup Plan was formulated and submitted to the NCDEQ for the site. The NCDEQ did not
direct implementation of the remediation plan, and continued groundwater monitoring has
been directed by the NCDEQ for this site. Pyramid recommends the implementation of the
NTCP for the site to (1) reduce the amount of free-product, and (2) provide a pathway to boost
the natural attenuation of groundwater contaminants with oxygen and nutrients necessary for
accelerated bioremediation. During the past 8 years of MNA (2014-2022) Free-Product levels
have increased and no appreciable cleanup has been observed at the site. Active remediation
is reasonable and necessary.

8.1 Soil Contaminant Mass Removal
The soil removal project in 1999 removed much of the petroleum contaminated soil mass
surrounding the former UST systems. Approximately 1,469 tons of petroleum contaminated soil
from under and around the former UST system area. Monitoring of the site since that time has
proven that there is still free-product downgradient of the former UST areas and that a smear
zone of adsorbed petroleum exists at the site which is not remediated.

In the prior CAP, no soil contaminant mass baseline nor projected remedial milestones were
established for the Sugar Grove Shell site.

8.2 Groundwater – Total Mass of Contaminant
Some of the petroleum contaminant mass was removed by (1) contaminated soil excavation
and (2) MMPE events completed at the site by Pyramid. Since February 2009, eight (8) MMPE
events have been completed at the site. The MMPE events are summarized in Table 8.

No groundwater mass baseline nor projected remedial milestones were established in the 1999
CAP or 2014 New Technology Cleanup Plan the for the Sugar Grove Shell site.

The groundwater mass of contaminant calculations are presented in Appendix E. Pyramid
calculated an estimated total mass of contaminant for groundwater, and the calculated a
comparison of the total mass of contaminant remaining at the end of September 2018. The
calculated total groundwater mass from 2008 was estimated to be 1.28E + 11 micrograms (see
Appendix E).

The calculated groundwater mass remaining was estimated to be 7.55E + 10 micrograms, and
the calculated groundwater was based on the September 2018 groundwater concentrations
Monitoring Report – Colvard Oil Company - Sugar Grove Shell 16 Pyramid Project No.: 2022-225 12/28/2022
and plume size. These calculations compared with 2008 calculations show as estimated
groundwater mass reduction of approximately 41%.

The calculated groundwater mass remaining was estimated to be 5.03E + 10 micrograms, and
was based on the October 2019 groundwater concentrations and plume size. These
calculations compared with 2008 calculations show as estimated groundwater mass reduction
of approximately 60%. This mass reduction was calculated on current groundwater
concentrations in the groundwater monitoring wells as NCDEQ directs. The Free Product
detected at the site represents a significant petroleum hydrocarbon mass that is NOT included
in the reduction calculations.

The calculated groundwater mass remaining was estimated to be 5.03E + 10 micrograms, and
was based on the October 2019 groundwater concentrations and plume size. These
calculations compared with 2008 calculations show as estimated groundwater mass reduction
of approximately 60%. The current calculated mass of dissolved petroleum was estimated to
be 5.49E + 10 micrograms, and was based on the August 2022 groundwater concentrations
and plume size. The current calculated groundwater mass is an increase from the previous
sampling event. The Free Product detected at the site represents a significant petroleum
hydrocarbon that is NOT included in the reduction calculations.

9.0 CONCLUSIONS

As requested by Colvard Oil and directed by the NCDEQ, Pyramid completed the groundwater
sampling event for the Sugar Grove Shell. The results of the assessment are summarized below:

• The Sugar Grove Shell site is located in a rural area where municipal water is not available.
All properties rely on private water supply wells for drinking water.

• The most recent receptors survey update (2015) was performed and found 5 supply wells
within 500 feet of the gasoline source areas and ten water supply wells between 500-1000
feet. The closest surface water is the Brushy Fork Creek, which is located downgradient,
approximately 400 feet to the south of the site.

• The closest water supply wells (WW-1 and WW-2) have been sampled many times and have
not shown petroleum impacts. These wells are within 30 feet of the most heavily
contaminated shallow groundwater monitoring wells. The petroleum contaminants appear
to be concentrated at the water table at 10-15 feet below land surface (BLS). The supply
wells are cased deeper and withdraw water from a deeper water bearing zone.
Monitoring Report – Colvard Oil Company - Sugar Grove Shell 17 Pyramid Project No.: 2022-225 12/28/2022

• The groundwater flow direction is northwest from the Colvard UST area toward the nearby
surface water stream (Cove Creek). Depth to groundwater at the site is between 1 to 13
feet below land surface.

• From 1998 through 1999, a CSA and a CAP were completed at the Sugar Grove Shell. The
previous consultant, found significant petroleum concentrations in the soil and
groundwater in the former UST area. In July 1999, approximately 1,469 tons of petroleum
contaminated soil was removed from the UST basin and pump island area on the Colvard
Shell site.

• The soil excavation removed much of the soil contamination in the former UST area;
however, downgradient migration of petroleum in the groundwater and free-product
remain. The gasoline free-product is the source of petroleum that is dissolving into the
groundwater and keeping groundwater concentrations above regulatory levels.

• The results of the August 2022 groundwater monitoring show that contamination in the
center of the petroleum plume area stayed the same and free-product remains at the site.

• The perimeter wells show that was groundwater contaminant plume is not expanding, and
remains within the existing monitoring well network.

• Dissolved concentrations were observed in many of the plume wells. Several wells were
not sampled due to substantial free-product thicknesses observed in August 2022 (MW-6,
MW-10, MW-16, and RW-1).

• Based on the conditions at the site, the site risk remains high risk.

The recent assessment showed that high concentrations of petroleum compounds and gasoline
free-product remain in the source area, and continued site remediation is recommended for
this High-Risk site.

10.0 RECOMMENDATIONS

The site is a high priority ranked site and municipal water will not be available to the site in the
foreseeable future. After reviewing the recent and historical data, Pyramid recommends
continuing with the remediation and monitoring.

Monitoring Report – Colvard Oil Company - Sugar Grove Shell 18 Pyramid Project No.: 2022-225 12/28/2022
• Pyramid recommends annual monitoring of nearby supply wells. Supply Wells WW-1 and
WW-2 are in or near the petroleum contamination area and are in close proximity to free-
product detected currently in MW-6 and MW-10, and MW-16. These two water supply
wells are cased in a deeper zone below the surficial water bearing zone. Although the
nearby water supply wells have not shown any petroleum impact, continued monitoring is
required.

• Pyramid recommends completing an MMPE event to recover free-product from MW-6,
MW-10, and MW-16 in the next two months followed by selected groundwater monitoring.

• Upon approval of the NTCP, Pyramid/Colvard Oil recommend implementation of the
selected Corrective Action for the Sugar Grove Shell.

11.0 CLOSURE

1 Enter the date the monitoring report was due. No due date was requested. Will this
report be submitted after the established due date? The report was delayed due to
NCDEQ’s new report requirements and formats.
YES NO
2 Was any required information from the above template missing from this report? YES NO
Not enough assessment work was completed to calculate the remaining soil
contaminant mass. Free-product is present in the smear zone.
3 If applicable, will any of the proposed attenuation milestones under the schedule approved
in the Corrective Action Plan not be met? (within a reasonable margin of error)
YES NO
No milestones established in the CAP or NTCP.
Monitored Natural Attenuation has not produced results in the past 5 years.
4 Does any known or suspected source zone soil contamination or free product remain
outside of the assessed area that could be inhibiting natural attenuation?
YES NO
5 Has there been an unexpected increase in contaminant mass sufficient to suggest a
potential new release from a separate onsite or offsite source?
YES NO
There are no remaining USTs at the site, and no new sources are expected.

1.0 Equipment Decontamination

Equipment decontamination is essential to assure representative environmental samples 
are collected and to eliminate the potential for cross‐contamination between sample points. 
Pyramid strives to clean all field equipment prior to leaving the office; however, field 
decontamination is still required on most projects. The procedures for decontamination of 
water level probes, hand augers, sampling probes, trowels, and other field equipment are 
listed below. 

1.1 EPA Region IV Decontamination Procedures  
Drilling and soil sampling equipment is decontaminated prior to each use using a pressure 
washer or steam cleaner. Reusable sampling equipment (hand augers, sampling probes, 
trowels, split spoon samplers, water sampling equipment, etc.…) are decontaminated using 
the general procedure described below.  
 Wash with non‐phosphate detergent, water, & brush to remove particulate matter 
 Rinse with tap water 
 Rinse with 10 percent nitric acid solution (only if sampling for metals) 
 Rinse with de‐ionized water 
 Rinse with pesticide‐grade isopropyl alcohol 
 Rinse with de‐ionized water 
 Air‐dry as long as possible  
The level of decontamination used is appropriate to the analytical parameters selected and 
the material of the sampling device being used for sampling. For example, if metals analyses 
are required, then the 10 % nitric acid solution is used for decontamination of stainless‐steel 
equipment. Pyramid uses de‐ionized or distilled water for decontamination. Equipment that 
is not used immediately after decontamination is wrapped in aluminum foil prior to storage. 

2.0 Soil Borings & Sampling
2.1 Soil Borings  
Soil borings are used by Pyramid to investigate and characterize the subsurface at sites.      
Soil borings provide information concerning soil types and density, depth to refusal, depth 
to bedrock, organic vapors that may be present, and can be used to obtain samples for 
laboratory analysis.  
Standard Field Procedures:  Revision 10.6                            Page 2 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
Pyramid conducts borings in several different ways, using hand augers, direct‐push 
equipment (Geoprobe), sample probes, split‐spoon samplers (ASTM D 1586‐84), auger 
drilling, air drilling, and Vibro‐Core. The following procedures are used by Pyramid 
Environmental when performing soil borings:  
1. Soil boring locations are chosen, and the ULOCO utility locating service is called to 
mark all public utilities. Pyramid locates private utilities at many project sites using 
Pyramid locating equipment, or uses a private utility locating service. 

2. Down hole drilling equipment is cleaned prior to use and between borings using 
pressure washing or steam cleaning. Additional decontamination procedures in 
Section 1.1 are used for sampling tools such as split spoons or direct‐push points.  

3. Soil borings are advanced using direct‐push, drilling rigs, hand augers, or other 
appropriate means. Near‐surface soil samples may also be collected using stainless 
steel push probes, shovels, scoops, or other sampling devices.  

4. Soil samples are normally collected at a minimum of 5‐foot intervals. Each sample is 
divided into two parts. Soil samples for laboratory analyses are jarred from the initial 
sample volume. The remaining soil is stored in a sealed container for headspace 
analysis and geological description.  

5. After screening the soil with the field instruments, each soil sample is described by 
the field geologist and a geologic description is recorded in project documentation. 

6. Soils are typically described in the field by the project geologist or soil scientist and 
are classified according to the Unified Soil Classification System (ASTM D 2488‐84). 

7. Soil samples selected for laboratory analysis are placed in properly prepared, 
laboratory supplied containers and immediately packed in a cooler on ice. Sample 
custody is maintained using standard chain‐of‐custody (COC) procedures through 
delivery to the analytical laboratory. 

8. Soil borings, which are not completed as monitoring wells, are grouted using a 
Portland cement, bentonite, or backfilled with soil cuttings.  

9. Soil cuttings are generally spread near the soil boring or monitoring well location as 
directed by State regulatory managers.  Drill cuttings are drummed (containerized) 
where site conditions or regulatory requirements prohibit spreading cuttings, and 
are disposed off‐site (after waste determination is made).

2.2 Soil Headspace Screening  
Soil samples are routinely screened for volatile organic compounds (VOCs) which may be an 
indication of organic or petroleum hydrocarbon contamination. The typical screening 
procedure includes immediately transferring the soil from the sampling devices to a sealed 
container (sealed 1‐gallon Ziplock plastic bag). The soil container is filled approximately 
halfway with soil and sealed. This creates headspace above the soil in which VOCs may 
accumulate. The container is allowed to stand for 5 to 15 minutes for the VOCs to equilibrate 
in the headspace of the container. The headspace of the container is then screened using a 
calibrated organic vapor analyzer (PID or FID). The screening is conducted by cracking the 
seal only enough to allow insertion of the probe into the headspace so as not to dilute the 
sample. In most cases where the contaminant of concern includes volatile organics, the 
highest or “Peak“ field‐screening result is documented for each sample. The soil samples 
showing the highest reading from each boring are typically selected for laboratory analysis. 

2.3 Soil Sample Collection for Laboratory Analysis   
After the targeted depth has been reached, soil samples are collected using a variety of 
sampling devices. Soil sample devices used include split‐spoons, stainless‐steel hand augers, 
stainless‐steel push‐probes and sampling scoops, and directly from the center of the 
excavator bucket. The sample technician uses disposable nitrile gloves, which are changed 
between samples to avoid cross‐contamination of samples, and each sampling device is 
decontaminated prior to use.  

Only laboratory provided containers are used for sample collection. Samples are collected 
in accordance with the preservation methods required by the requested analytical method. 
Samples are handled as little as possible and preserved in the field as specified for the 
analytical method. The samples are stored and transported to the laboratory in an insulated 
cooler chilled to approximately 4 degrees centigrade. The samples are labeled with a 
minimum of the following information: Pyramid, project name or number, sample 
identification, date collected, sampler name, and analysis requested. Sample custody is 
maintained using standard chain‐of‐custody procedures through delivery to the analytical 
laboratory. Notes of the sampling events are recorded in project documentation. 
Incremental sampling methodology (ISM) is a structured composite sampling and 
processing protocol that reduces data variability and provides a reasonably unbiased 
estimate of mean contaminant concentrations in a volume of soil targeted for sampling. 
ISM provides representative samples of specific soil volumes defined as decision units 
(DUs) by collecting numerous increments of soil (typically 30–100 increments) that are 
combined, processed, and subsampled according to specific protocols. ISM Sampling will 
be further explained in a site‐specific Work Plan documents. 
Pyramid will contract an on‐site laboratory for immediate analyses as needed.

2.4 Sediment Sample Collection for Laboratory Analysis   
Near surface sediment may be present in a surface water ditch, stream, or dry intermittent 
stream bed. Sediment samples are typically soil related samples and may be collected with 
a variety of sampling tools. Pyramid will use stainless‐steel samplers which have been 
decontaminated according to the procedure detailed in section 1.1 of this document. After 
the sediment samples are collected, the location, depth, conditions, and sample 
composition are documented in the project records. The samples will be screened in the 
field to detect volatile organic vapors and visually examined for contamination. Sediment 
samples will be preserved in laboratory prepared containers in accordance with sample 
preservation recommendation of the analytical laboratory. Samples are handled as little as 
possible and preserved in the field as specified for the analytical method. The samples are 
stored and transported in an insulated cooler chilled to approximately 4 degrees centigrade. 
The samples are labeled with a minimum of the following information: Pyramid, project 
name or number, sample identification, date collected, sampler name, and analysis 
requested. Sample custody is maintained using standard chain‐of‐custody procedures 
through delivery to the analytical laboratory. Documentation of the sampling events are 
recorded in the project documentation. 

3.0 Direct-Push Sampling Procedures

Direct‐push sampling techniques have been used at many sites to collect soil and 
groundwater samples rapidly and inexpensively.  Track‐mounted, direct‐push rigs can access 
hard to reach areas and allow borings and monitoring wells to be installed.  For soil sampling, 
typically, the direct‐push steel drive tube is decontaminated using a pressure washer, and a 
new plastic sample liner is inserted in the steel drive tube to collect soil samples. The soil 
samples are collected in new polyethylene sample tubes within the steel drive tube. The soil 
samples are then extracted from the polyethylene liner and preserved as required for 
laboratory analysis. 

For groundwater sampling, a steel probe with a retractable screen section and tubing are 
driven to depth and the screened section is opened to allow groundwater to enter the 
tubing. The water samples are withdrawn using new polyethylene and Teflon® tubing with 
either a decontaminated stainless‐steel check ball, or peristaltic pump. The groundwater 
sample is placed directly into the appropriate laboratory containers and sealed immediately. 
To prevent cross‐contamination of samples, new disposable tubing is used for each 
groundwater sample point. Disposable nitrile gloves are worn by field personnel during 
development and groundwater sampling, and gloves are changed between samples. 
Groundwater sampling procedures are detailed more in Section 5.0, as appropriate for each 
analytical method.

4.0 Monitoring Well Installation

Groundwater monitoring wells are installed in many subsurface environments; Coastal 
Plain, sedimentary, Piedmont saprolite, weathered rock formations, and mountain terrains 
to list a few. Formations encountered include unconsolidated and consolidated sediments, 
fill material, organic soils, saprolitic soils, weathered rock formations, and bedrock. 
Groundwater monitoring wells provide a stable sampling point at discrete intervals within 
the confined or unconfined aquifers. Monitoring wells are installed for a number of reasons, 
and are typically installed as 1‐inch, 2‐inch, 4‐inch, or 6‐inch diameter wells. Construction 
may be of PVC, stainless‐steel, HDPE, or other appropriate materials. The following 
procedures are used by Pyramid when performing borings and monitoring well installations.   If required, monitoring well permits are obtained from the State, County, or City. 
 Boring and monitoring well locations are chosen, and utilities are marked by the 
public utility locating company. As needed, the locations may be scanned for utilities 
by Pyramid using our locating equipment, or a private utility locating company. 
 In selecting a drill site, care is taken to avoid overhead power lines, and subsurface 
utilities whenever possible. 
 Down‐hole drilling equipment is decontaminated prior to use and between borings. 
 Borings are advanced using direct‐push, drilling rigs, hand augers, solid‐stem augers, 
hollow‐stem augers, air rotary drilling, or air hammer drilling. 
 Soil samples are normally collected at a minimum of 5‐foot intervals. Each sample is 
divided into two parts.  Soil samples for laboratory analyses are jarred from the initial 
sample volume. The remaining soil is stored in a sealed container for headspace 
analysis with an organic vapor analyzer (PID or FID).  
 After screening the soil with the field instruments, each soil sample is described by 
the field geologist and a geologic description is recorded in the project 
documentation. 

Type II monitoring wells are usually installed using 2‐inch diameter schedule 40 PVC riser 
and 2‐inch, 0.010‐inch machine slotted well screen. The screened interval length varies with 
the geologic site conditions, expected variations in water level, and the investigation goals 
for the well. The well construction details are presented on the boring log. 

Type III wells are usually installed as double‐cased wells to monitor the deeper portions of 
the aquifer. The first casing is usually a 5 to 6‐inch diameter solid PVC well casing drilled to 
bedrock or an appropriate depth within the surficial zone. The 5 to 6‐inch diameter casing 
is then set and grouted in the borehole. After the cement grout has set for 12 to 24‐hours, 
the borehole is completed to the desired depth using air rotary drilling or air hammer 
drilling. The inside casing of the Type III monitoring well is usually constructed of 2‐inch 
diameter SCH 40 PVC casing and 2‐inch diameter SCH 40 PVC 0.010‐inch slotted well screen. 

Standard Field Procedures:  Revision 10.6                            Page 6 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
In most applications, a sand filter pack of #2 well sand (or appropriately sized well sand).  
Sand is typically installed to a level of 2 feet above the top of the screen in each well.                   
A minimum 2‐foot thick bentonite seal is usually placed on top of the filter pack and 
hydrated with de‐ionized or distilled water. The remaining annular space of a typical well is 
backfilled to grade with a Portland cement/bentonite grout. In monitoring wells where the 
water table is close to surface, the amount of sand above the screen and bentonite will be 
reduced to allow for a minimum of 2–3 feet of cement grout in the well bore. 

At the surface, each well is secured with a locking cap and a steel well protector. Depending 
on the surface conditions, the well may be protected by a flush‐mounted manhole set in the 
surrounding surface in a concrete pad.  In some cases, stick‐up well protectors are used to 
secure the well and allow the well to be more easily located in wooded or open areas. 

Each groundwater monitoring well is developed by surging, pumping, or bailing to remove 
sediment before sampling. Water removed during development is managed according to 
individual State regulatory guidance. 

5.0 Water Sampling Procedures

Pyramid relies on water sampling as a primary method for assessment of subsurface 
groundwater conditions. Water sampling typically includes sampling groundwater from 
monitoring wells, water supply wells, surface water bodies, stormwater,  waste sumps, etc.   
The following provides typical sampling procedures for the water samples. 

5.1 Monitoring Wells  
Prior to sampling each monitoring well, depth to liquid and/or liquids and total well depth 
are measured using a properly decontaminated electric interface probe. If phase‐separated 
petroleum product is detected in a well, the product measurements are recorded along with 
the water level in each well.  This information is recorded in the field record and the volume 
of the water in the well casing is calculated. To purge stagnant water from each monitoring 
well, three to five well casing volumes of water are removed from each well prior to 
sampling. Alternately, for low‐flow sampling, development continues until the field 
parameters (pH, conductivity, dissolved oxygen, ORP, and temperature) have stabilized.   
If the water in the monitoring well is removed until the well is dry, then the well is sampled 
thereafter. Water removed from wells during purging is managed in accordance with 
individual State regulatory guidance.  

Groundwater samples are typically collected using a new disposable polyethylene bailer and 
a new length of nylon cord. To prevent cross‐contamination of samples between wells, a 
new disposable bailer is used for each well.  The bailer is lowered into the groundwater 
Standard Field Procedures:  Revision 10.6                            Page 7 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
slowly and removed slowly.  A new pair of disposable gloves is worn by field personnel 
during purging and sampling, and is changed between wells.  In the case of small diameter 
monitoring wells or direct‐push water samples, water samples may be collected using a 
peristaltic pump and new polyethylene tubing.  Another method is to use a segment of new 
sampling tubing and a stainless‐steel check ball to create a “Tube Bailer”.  
Groundwater samples selected for laboratory analysis are immediately placed in properly 
prepared, laboratory supplied containers and preserved in a cooler on ice. Samples are 
maintained under standard chain‐of‐custody procedures from sample collection through 
laboratory analysis. 

5.2 Water Supply Well Sampling  
Prior to sampling each water supply well, the well owner is contacted to provide access to 
the well. The well owner is interviewed to locate the faucet closest to the well for sampling.    
If there are no faucets located on the well, then water from an outside faucet at the building  
is usually sampled. If there are no outside faucets available, then the water samples are 
collected from an inside faucet. The location of the sample is recorded in the field record.  
The owner is interviewed to see if there is a chlorination system on the well, or if the well 
has been recently chlorinated. Recent chlorination could affect the laboratory detection 
limits. In most cases, the samples are preserved using sodium thiosulfate or ascorbic acid to 
remove the interactions of chlorine, which may be present in the samples.   
If the well is treated with a Point‐of‐Entry (POE) treatment system, then the “raw” water 
sample must be collected before the treatment system. An associated treated water sample 
is usually collected as well to demonstrate effective treatment.    
To purge stagnant water from the water supply well system, the faucet is allowed to run on 
full stream for a minimum of 15 minutes. The aerator is removed from the tap if one is 
present. Water removed from wells during purging is managed according to regulatory 
standards.  
Water supply well samples are collected using appropriate laboratory prepared containers 
for each analysis.  The analytical methods selected will vary with the contaminant of 
interest. To prevent cross‐contamination of samples between wells, disposable nitrile gloves 
are worn by field personnel during purging and sampling and are changed between wells. It 
is possible that samples may be required at several places within the water supply system. 
The samples are collected accordingly and labeled to show the source and location sampled.  
Supply well samples selected for laboratory analysis are immediately placed in properly 
prepared, laboratory supplied containers and packed in a cooler on ice, and chilled to 
approximately 4 degrees Celsius.  Samples are maintained under standard chain‐of‐custody 
procedures from sample collection through laboratory analysis. 

Standard Field Procedures:  Revision 10.6                            Page 8 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
5.3 Surface Water Sampling  
Surface water samples are obtained using several techniques including use of sample 
bailers, discrete depth interval samples, sample scoops, from boats, bridges, or wading into 
a stream. Caution should always be used when sampling surface water to ensure that the 
water collected is representative of the site conditions. Since stream or open water sampling 
is transient, careful documentation of the site conditions, weather, surface conditions, 
sediment, algal or biological material, etc. is required.  

In many studies, additional samples from upstream and downstream of the desired sample 
point are required. Surface water sampling must be planned to reflect the site‐specific 
conditions during sampling. The general procedures are similar to the supply well sampling 
procedures detailed above. Appropriate laboratory prepared containers are used for each 
analysis. The analytical methods selected will vary with the contaminant of interest. 

To prevent cross‐contamination of samples between samples, disposable nitrile gloves are 
worn by field personnel during purging and sampling and are changed between samples. It 
is possible that samples may be required at several places along the stream to check for 
influences of up‐stream facilities.  Samples will be collected accordingly and labeled to show 
the source and location sampled. Sample will always be collected upstream of the area 
disturbed by the person sampling the stream. Surface water samples selected for laboratory 
analysis are placed in properly prepared, laboratory supplied containers and immediately 
packed in a cooler on ice. Samples are maintained under strict control using standard chain‐
of‐custody procedures through laboratory analysis.  

6.0 Quality Assurance / Quality Control

The field and laboratory procedures listed above have been implemented on many sites 
with excellent results. The procedures are often verified by an appropriate use of the 
following environmental samples. 

Trip Blanks ( or Travel blanks) 
The Trip Blank (or travel blanks) are often used to verify that the environmental samples are 
not impacted during shipping, and verify that the source of the glassware is not the source 
of contamination. The trip blanks are preserved de‐ionized water, collected in the 
laboratory, and shipped with the sample containers to Pyramid or the site. The trip blank 
remains in the sample cooler and is shipped back to the laboratory with the environmental 
samples. The trip blank is most commonly analyzed for volatile organic compounds (VOCs), 
and correspond to the target analyses. 

Standard Field Procedures:  Revision 10.6                            Page 9 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
Field Blanks  
Field Blanks are quality assurance samples which are collected in the field to represent the 
conditions present at the time the samples are collected. For water samples, the laboratory 
containers are opened and filled in the field using de‐ionized (or distilled) water from a 
known source.  The samples reflect any site conditions such as vapor sources which may 
affect the water samples.  The samples then travel to the laboratory with the other samples 
for analysis. Comparison of the field blank results with the sample results may indicate a 
pervasive site constituent detected in the samples.  

Equipment Blanks  
Equipment Blanks are used to verify whether the decontamination procedures used for the 
sample equipment (or the new equipment) may have added any contaminants to the 
sample during collection. If a non‐disposable sampling device is used (such as a sampling 
treir, scoop, hand auger, Teflon bailer, etc.…), then the decontamination of the sampling 
device is usually verified using an equipment blank. The equipment blank is collected using 
de‐ionized (or distilled) water from a known source. The equipment is decontaminated,  
allowed to air dry, the water is poured over (or through) the equipment, and a sample is 
collected in the appropriate sample containers. The equipment blank samples are preserved 
with the other environmental samples, and shipped for analyses for the target parameters. 

Duplicate Samples 
Duplicate Samples are used to verify the sampling procedures and evaluate laboratory 
analysis variability. The duplicate samples may be collected from soil, sediment, air, surface 
water, wastes, or groundwater. These samples are collected and sent to the laboratory as  
blind samples to have maximum effectiveness. Duplicate samples are generally analyzed for 
the same analytical methods as the actual environmental sample for direct comparison. 
Duplicate samples may also be split between two different laboratories to provide 
verification of laboratory detection limits or quality process verification. 

Background Samples 
Background Samples are a tool for comparison of general site conditions with source area 
site conditions. Background samples may be soil, sediment, air, surface water, waste, or 
groundwater. The goal is to reflect conditions outside the expected area of contamination. 
These samples are collected outside the expected area of contamination and sent to the 
laboratory for analyses. Background samples are generally analyzed for the same analytical 
methods as the source area environmental samples for direct comparison. Background 
samples for metals comparison are common types of background samples used in 
environmental investigations.

RE: Supply Well (WW-1) Analytical Results for the Property at
1199 US Hwy 321, Sugar Grove, NC
NCDENR Incident #18455 Sugar Grove Shell
Pyramid Project # 2022-225
Dear Mr. & Mrs. Townsend: Thank you for your help for our ongoing efforts at the Sugar Grove Shell site. As we have been directed by the State of NC DENR and Colvard Oil Company, Pyramid Environmental has collected a sample from the water supply well on your property as part of the ongoing
assessment of the referenced nearby underground storage tank release. The results of these analyses are presented below. On August 18, 2022, Pyramid collected groundwater samples from your supply well. The groundwater samples were analyzed at a State Certified laboratory and the results are attached
for your review. The laboratory results showed that no petroleum compounds were detected at concentrations that exceeded the laboratory detection limits. Colvard Oil Co. and Pyramid may request sampling of your well in the future to assist with further investigations. If you have any questions, please call Pyramid at [phone]. Thank
you for your cooperation with this project. Sincerely,
