Monitoring Report General Store of Denver
Sherrills Ford, North Carolina H&H Job No. GSD-050
1.0 Introduction

On behalf of FMC Properties, LLC, Hart & Hickman, PC (H&H) has completed a Monitoring
Report for the General Store of Denver (GSD) facility located at 6360 NC Highway 150 East in
Sherrills Ford, Catawba County, North Carolina. The GSD facility is a grocery and retail
petroleum distribution facility. A hardware store is also located at the site. The North Carolina
Department of Environmental Quality (DEQ) groundwater incident number is 18450, and DEQ
has assigned the site a high-risk classification due to the presence of nearby water supply wells.
A site location map is included as Figure 1, and a site map is included as Figure 2.

During the current six-month reporting period, H&H operated the pump and treat system
between September 2023 and December 2023. As recommended in the December 2023
Corrective Action Performance Report (CAPR) that DEQ approved in a subsequent
Acknowledgment of Receipt letter dated December 20, 2023, the treatment system was shut
down on December 29, 2023. Monitored Natural Attenuation (MNA) closure sampling was
initiated at that time.

This report documents the performance of the remediation system operation and maintenance
(O&M) activities for the period of September 2023 through December 2023 and the first semi-
annual MNA closure sampling event conducted in February 2024.

2.0 Site History

A kerosene UST was removed from the site in March 1998 and impacted soil was detected. Two
other surface releases of petroleum also are documented at the site. At the time of assessment
and corrective action planning, municipal water was not available. However, a waterline has
since been installed adjacent to the site, and municipal water is available in the vicinity of the
site.

Assessment conducted at the site since 1998 indicated on-site groundwater is impacted with
benzene and MTBE at levels above the North Carolina groundwater standards but below DEQ-
defined Gross Contamination Level (GCLs). The impacted groundwater is primarily detected
within the fractured bedrock underlying the site. Additionally, benzene and MTBE were
historically detected in six off-site water supply wells. The impacted wells are oriented along a
north-northeast trend coincident with the dominant fracture trend in the area. The furthest
historically impacted water supply well from the site is located approximately 1,500 ft from the
source area.

A Corrective Action Plan (CAP) was submitted to DEQ on November 27, 2002 recommending
active remediation of the soil by vapor extraction coupled with a groundwater remedy involving
lowering the site risk by means of alternate water supply. DEQ requested that an aquifer test be
conducted and requested additional information regarding potential implementation of active
remediation using groundwater pump and treat. An addendum with the supplemental
information was submitted to DEQ on May 5, 2003 and approved in a Notice of Regulatory
Requirement (NORR) dated May 19, 2003. Soil remediation by vapor extraction was not
approved by DEQ.

Design and other tasks required to implement the remedial option began immediately. However,
the installation and operation of the treatment system was delayed due to requirements for the
National Pollutant Discharge Elimination System (NPDES) discharge permit and required access
agreement from the North Carolina Department of Transportation for discharge to a dry
stormwater conveyance swale located north and adjacent to the site. The installation of the

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/General Store of Denver - GSD/GSD-050/032024/Monitoring Report/MO-5325_18450_CA_MRP_20240405_Monitoring Report.doc
groundwater recovery and treatment system was completed in August 2004, and system
operation commenced on August 13, 2004. The groundwater recovery and treatment system
operated until July 29, 2005 at which time the system was deactivated per DEQ’s July 2005
NORR indicating the work at the site was no longer directed.

Municipal water was extended to the site in late 2004 and early 2005. At DEQ’s request, H&H
conducted a limited water supply well survey in June 2005 to determine the status of municipal
water connections at that time. Based partially on the data in the well survey, on July 15, 2005
DEQ issued a NORR indicating the site did not meet the requirements for further assessment or
corrective action. Therefore, the system was shut down pending further direction from DEQ.

DEQ issued another NORR on January 26, 2006, indicating the site was of sufficiently high
priority to allow funding by the State Trust Fund Program and that work indicated in the NORR
dated May 19, 2003 was directed to proceed.

H&H completed a water supply well survey update for the area within a 1,500-ft radius of the
former UST basin in 2020. H&H identified the presence of 29 water supply wells within 1,500
ft of the UST basin (Figure 3). Of these 29 water supply wells, 18 are used for drinking water
and one is used for non-drinking water purposes only. The remaining 10 water supply wells are
not active. Municipal water is provided to the site and is available to properties within a 1,500-ft
radius of the site. Water supply well owner information is presented in Table 1.

3.0 Groundwater Sampling

3.1 Water Levels

The first semi-annual MNA closure sampling event was conducted on February 6, 2024. During
the event, H&H inadvertently neglected to collect water levels in the site wells. Water levels
will be collected from site wells during the next semi-annual sampling event. Historical water
level measurements are summarized on Table 2. A potentiometric map based on data collected
from the deep wells in September 2023, along with knowledge of prior data, is presented as
Figure 4. Historical potentiometric data indicate that groundwater flow at the site is generally to
the northeast.

3.2 Monitoring Well Sampling

Deep recovery wells MW-3D and MW-5D were sampled on February 6, 2024. Groundwater
samples were poured in laboratory supplied containers, marked with identifying labels, and
placed in an iced cooler for shipment under chain-of-custody to a certified laboratory for
analyses. Groundwater samples were analyzed for volatile organic compounds (VOCs)
including methyl tertiary butyl ether (MTBE), isopropyl ether (IPE), and xylenes by EPA
Method 6200B (Table 3). The laboratory analytical reports are provided in Appendix A.

During the February 2024 sampling event, benzene was not detected above the laboratory
detection limit and MTBE (616 µg/l) was detected at a concentration above the North Carolina
Administrative Code, Subchapter 2L Groundwater Standards (2L Standard) in MW-3D. The
detected MTBE concentration was not above the GCL. Additionally, benzene and MTBE were
not detected above the laboratory detection limits in monitoring well MW-5D. A graph showing
the benzene and MTBE concentrations with time for MW-3D, MW-5D, and the system influent
is presented in Appendix B. Due to the nature of the petroleum impacts in fractured rock and the
limited extent of VOC groundwater detections, isoconcentration maps cannot be prepared.
However, benzene and MTBE concentrations for the February 2024 groundwater sampling event
are presented on Figure 5.

4.0 Water Supply Well Sampling

H&H collected samples from the Former Daycare Well (Map ID 16) and Keller/Rawlings #2
water supply well (Map ID 37) on November 20, 2023 and February 6, 2024. The former
Daycare Well is not used for drinking water and bottled water is provided, as needed. The
property using the Former Daycare Well for non-potable water is occupied by a musician that
uses the building for instrument sales and instrument lessons. Samples collected were submitted
to a North Carolina certified laboratory for analysis of VOCs by EPA Method 6200B. The
analytical data reports for the water supply well sampling events are included in Appendix A.

No target compounds were detected above the laboratory detection limits in the Former Daycare
well and the Keller/Rawlings #2 well in November 2023 and February 2024. Historical supply
well sampling data are presented in Table 4. The recent results are also provided on Figure 3.

Based on approval from DEQ, the Christenbury water supply well has not been sampled since
October 2006 because of the prior consistent absence of petroleum compounds in the water well
samples. The Rawlings/Abernathy well was not sampled because the well has been inoperable
since the October 2006 sampling event. The trailer home at the Rawlings/Abernathy well
property is currently vacant, and the property has been connected to city water. The Bach/Innes
well has been decommissioned due to extension of the municipal waterline to the area. As such,
the multiple prior users of this well have been connected to municipal water.

5.0 Remediation System

5.1 General Description
The recovery/treatment system is comprised of groundwater recovery via pneumatic pumps and
treatment via air stripping and carbon polishing. Treated groundwater is discharged via NPDES
General Permit NCG510000 under Certificate of Coverage NCG510500.

As directed by DEQ, groundwater is recovered from two existing bedrock monitoring wells and
treatment of the recovered groundwater is conducted using a low-profile air stripper and carbon
polishing located within a dedicated 10 ft x 10 ft treatment building. The treated groundwater is
then discharged to a stormwater swale located approximately 140 ft away and topographically
downgradient of the system under the NPDES General Permit NCG510000. The locations of the
system components are indicated on Figure 2. A schematic of the recovery and treatment system
components is indicated on Figure 6.

5.2 Groundwater Recovery
The system utilizes two pre-existing bedrock monitoring wells (MW-3D and MW-5D) for
groundwater recovery per DEQ’s requirements in their May 19, 2003 CAP approval letter.
These wells are two-inch diameter PVC monitoring wells. MW-3D is 85 ft deep and MW-5D is
95 ft deep. These wells have historically contained the highest concentrations of petroleum-
related constituents at the site.

Groundwater was previously recovered from each well using controllerless, top-loading,
pneumatic pumps (CEE Model AP-2). The pumps were discovered to be malfunctioning in June
2018. As a result, 2-inch diameter 48-inch long pneumatic pumps (QED Model Genie Pumps)
were installed in each well on July 2, 2018.

The air supply for the pneumatic pumps is from a 1.5 horsepower (hp), industrial duty,
reciprocating, two stage, splash lubricated, Saylor-Beall air compressor. This compressor is

designed to deliver 7.3 standard cubic ft per minute (scfm) of air at 100 pounds per square inch
(psi).

5.3 Groundwater Treatment
Figure 2 indicates the layout of the treatment system. Groundwater recovered from the
monitoring/recovery wells is pumped via sub-grade piping to the treatment system housed in a
dedicated treatment building located east of the hardware store. The system contains a surge
tank, an air stripper, a blower, two carbon canisters installed in series, and associated controls.

Recovered groundwater is pumped to a 220-gallon, molded polyethylene surge tank equipped
with high-high-, high-, and low-level switches. When the high-level switch is tripped, the
groundwater is pumped to the air stripper via a ½ hp centrifugal transfer pump (American
Stainless Model #SSPC1) through an Amtek #PBH polypropylene vessel containing a 25-micron
filter bag.

The air stripper is a Northeast Environmental Products (NEEP) ShallowTray Model 2331-P
constructed of three Series 2300 polyethylene trays. After treatment via air stripping, the
effluent is pumped through a carbon-polishing unit. Two 300-pound carbon vessels (TetraSolv
Model AFD#85) are set up in series and filled with 8 x 30-mesh carbon. The carbon is used as a
polishing step and, due to the efficiency of the air stripping, it is not expected that breakthrough
of petroleum constituents will occur within the project life. Sampling ports are installed prior to
the surge tank, after the air stripper but before carbon polishing, between carbon vessels, and
after the carbon vessels.

A dedicated control panel is part of the treatment system. The controls prevent discharge of
untreated water by shutting off the recovery pumps when the surge tank is full and/or in the
event of an air stripper malfunction. A flow meter is installed at the system discharge to measure
the treated effluent volume.

The system was initially activated in August 2004 and was deactivated in July 2005 per DEQ’s

8
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/General Store of Denver - GSD/GSD-050/032024/Monitoring Report/MO-5325_18450_CA_MRP_20240405_Monitoring Report.doc
July 2005 NORR indicating the work at the site was no longer directed. At the time of
deactivation, 101,581 gallons of groundwater had been recovered and treated. The system was
reactivated on May 19, 2006. On that date, H&H revisited the site, installed new carbon drums
due to leakage developing during system inactivity, and restarted the system. During the system
shutdown, the internal flow meter battery had discharged and the flow meter reset to zero.

On August 18, 2017, H&H discovered that the treatment system carbon drums were leaking. As
a result, the system was shut down in order to replace the drums. In September 2017, DEQ Trust
Fund requested that the system be repaired and remain off until its effectiveness could be further
evaluated. The system carbon drums were replaced on November 17, 2017. In late 2017, DEQ
requested that the treatment system be restarted. As a result, the system was reactivated on
March 20, 2018. As stated above, new 2-inch diameter 48-inch long pneumatic pumps (QED
Model Genie Pumps) were installed in each recovery well on July 2, 2018.

5.4 Operating Status

The treatment system operated as designed between September 2023 and December 2024.
Because the treatment system has reached asymptotic levels and continued operation of the
system to achieve 2L Standards is no longer cost-effective nor feasible, H&H recommended
discontinuing active groundwater remediation and initiating MNA closure sampling in the
December 2023 CAPR. DEQ approved system shutdown and MNA closure sampling in the
Acknowledgment of Receipt letter dated December 20, 2023. Based on DEQ approval, the
system was shut down on December 29, 2023.

5.5 Groundwater Treatment System Sampling

During the current reporting period, influent and effluent samples were collected on August 16,
2023 and November 20, 2023 and analyzed for oil and grease, total phenolics, total suspended
solids (TSS), lead, and VOCs. The VOCs analytes included benzene, ethylbenzene, toluene,
xylenes, MTBE, naphthalene, and 1,2-dichloroethane as required by the NPDES permit.
Laboratory analytical data are provided in Appendix A. Table 5 summarizes the analytical

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/General Store of Denver - GSD/GSD-050/032024/Monitoring Report/MO-5325_18450_CA_MRP_20240405_Monitoring Report.doc
results and the historical influent and effluent sampling results. Select target VOCs were
detected in the influent samples. The August and November 2023 effluent results indicated no
detectable concentrations of VOCs.

Table 6 summarizes the mass removal for benzene and MTBE using the remediation system.
During the current reporting period, approximately 0.07 lb of MTBE was removed from the
groundwater. Based on the influent sampling results, no benzene was removed from
groundwater during the current reporting period. Overall, approximately 0.3 lb of benzene and
11 lbs of MTBE were removed from groundwater during the treatment system operation (Table
6).

5.6 Cleanup Progress Milestones

As previously indicated, a CAP was submitted to DEQ in November 27, 2002 recommending
active remediation of the soil by vapor extraction coupled with a ground water remedy involving
lowering the site risk by means of alternate water supply. On March 31, 2003, DEQ issued
correspondence to the General Store requesting additional activities in response to the CAP
submitted on November 27, 2002. The DEQ correspondence indicated that the CAP would not
be approved as DEQ believed pump and treat was the only acceptable remedial method.

Due to the uncertainty in implementing an active remedy of this type in the complex fracture
rock environment at the General Store, H&H has conducted ongoing evaluation of system
performance and applicability in meeting the project objectives outlined in the November 2002
CAP. Additionally, the General Store has periodically evaluated lowering the site risk to low by
providing a long-term alternate water supply to surrounding water supply users. Several
connections have been completed during the historical remediation period; however, active
drinking water wells still exist surrounding the site.

In an attempt to expedite site closure, in April 2021 DEQ requested that H&H evaluate
connecting the remaining drinking water wells within a 1,000 ft radius of the site to the
municipal water supply. A total of six water supply wells would need to be abandoned to lower

10
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/General Store of Denver - GSD/GSD-050/032024/Monitoring Report/MO-5325_18450_CA_MRP_20240405_Monitoring Report.doc
the site risk. Currently, only the owner of the Former Daycare Well (Map ID 16) has agreed to
connect to the municipal water supply. H&H has received a Task Authorization (TA) from the
State Trust Fund for the estimated costs to connect this well user to the municipal water supply.
Hickory Water and Sewer requires that the land owner sign the water connection application in
person at their office. To date, H&H has been unable to schedule a day to meet with the well
owner at Hickory Water and Sewer based on their current work schedule.

Current remediation performance monitoring requires milestones be established for the site.
Remediation milestones were not originally included in the CAP because pump and treat
technology was not the H&H selected remedial alternative and based on the requirements at the
time when the CAP was prepared. However, during H&H’s evaluation of treatment alternatives,
pump and treat combined with soil vapor extraction was estimated to take approximately 5 to 10
years to achieve site closure. Because soil vapor extraction was not approved by DEQ, the time
for cleanup was extended. Based on historical groundwater system operation and sampling data
from the site, in 2017 H&H re-evaluated the anticipated time to achieve site closure and
estimated the cleanup progress milestones as presented in Table 7. Because benzene and MTBE
are the only compounds present at concentrations above groundwater standards, only mass
milestones for these compounds (combined) were calculated and included in the table.

The initial step was to calculate the initial plume mass where benzene and MTBE concentrations
exceeded groundwater standards. Using pre-pumping data from October 2003, initial plume
mass in two areas were calculated: for the plume center (Figure 4) and the remainder of the
plume (Figure 5). The average benzene and MTBE concentrations for MW-3D and MW-5D
were utilized for the central portion of the plume where more substantial contaminant mass is
present, and the average benzene and MTBE concentrations for two water supply wells
(Rawlings/Abernathy and Former Daycare) were utilized for the remainder of the plume. The
plume mass was calculated by Area of Water (v) x Plume Thickness (d) x Average
Concentrations of Benzene and MTBE (c) x Porosity of Aquifer (n) using the following
assumptions:
• Porosity (n) of 0.1 for fractured bedrock;
• Plume thickness (d) of 30 ft based on CAP;

11
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/General Store of Denver - GSD/GSD-050/032024/Monitoring Report/MO-5325_18450_CA_MRP_20240405_Monitoring Report.doc
• Initial area of plume center near MW-3D/5D (v) of 11,232 ft2; and,
• Initial area of remaining plume (v) = 389,637 ft2.

Then, a mass concentration for the plume at site closure was calculated using the above formula
and based on the groundwater standards of 1 µg/l for benzene and 20 µg/l for MTBE.
Current/closure remaining plume areas (v) of 11,232 ft2 (plume source area) and 37,142 ft2
(remaining plume area) were utilized to estimate the alternate allowable plume mass at site
closure. The plume center area discussed above was utilized in the calculations. The estimated
extent of the central plume area is depicted on Figure 5, and pre-pumping and current plumes are
depicted on Figures 7 and 8, respectively.

Using the initial plume mass, H&H calculated mass reduction milestones until the plume mass
corresponding to the DEQ groundwater standards for benzene and MTBE would be achieved.
As presented in Table 7, H&H anticipated that the remediation system would take at least 25
years to achieve DEQ groundwater standards and site closure. When the system was shut down
in December 2023, it had operated for approximately 19.5 years.

The average groundwater concentrations for MW-3D, MW-5D, and supply wells
Rawlings/Abernathy and Former Daycare (if detections identified) were utilized to estimate the
mass reduction rates. The most recent sampling data from February 2024 indicate the system
had achieved an estimated mass reduction of approximately 89% from the baseline mass of 7.13
lbs to 0.77 lbs. H&H will continue to evaluate and update the milestone table during the MNA
closure sampling events.

6.0 Conclusions and Recommendations

The General Store of Denver is a high-risk site due to water supply wells within 1,000 ft of the
source area. H&H collected samples from the Former Daycare and Keller/Rawlings #2 water
supply wells in November 2023 and February 2024. No target compounds were detected in
samples collected from these wells during the sampling events.

As approved in the DEQ Acknowledgment of Receipt letter dated December 20, 2023, the
treatment system was shut down and an MNA closure sampling period was initiated on
December 29, 2023. No treatment system shutdowns were encountered during the final system
operational period from September to December 2023. At the end of the time period described
in this report, the system had completed approximately 19.5 years of active remediation since
startup in 2004. The milestone for 19.5 years of active remediation indicates an estimated mass
reduction of approximately 81.5% from the initial estimate. The current estimate, based on
February 2024 groundwater data, indicates a mass reduction of approximately 89% from the
initial mass estimate. While the mass reduction has been variable during system operation, these
data show that the system and natural attenuation have potentially been effective at slowly
removing VOCs at the site and the current milestone criteria have been met.

Monitoring wells/recovery wells MW-3D and MW-5D were sampled as part of the first MNA
closure sampling event in February 2024. MTBE was detected at a concentration above the 2L
Standard in MW-3D, and benzene and MTBE were not detected above the laboratory detection
limits in monitoring well MW-5D.

The groundwater plume appears to be shrinking and the potential for site groundwater to impact
surrounding water supply wells appears to be low. H&H recommends continuing the MNA
closure sampling plan consisting of semi-annual water supply well and monitoring well sampling
events. The next semi-annual MNA closure sampling event will be conducted in August 2024
with reporting in September 2024. As part of the next semi-annual reporting, H&H will evaluate
plume stability for groundwater impacts at the site. The evaluation will include performing a
Mann-Kendall statistical analysis of the VOC data in site wells. Should the results of the

the municipal water supply.

1. Remediation of soil not required by DEQ due to low levels remaining in soil; therefore, soil mass not included in total mass milestones. Approved Corrective Action Plan for groundwater remediation of fractured bedrock only.
2. Mass calculated by multiplying the analytical results by the representative volume using: Area of Water (v) x Plume Thickness (d) x Average Concentrations of Benzene and MTBE (c) x Porosity of Aquifer (n) (see below for assumptions).
3. Removed mass calculated by system effluent monitoring, multiplied by total volume extracted by the system during that period.
4. Reduction rate equals the % reduction from the prior mass (current Total Mass ÷ prior Total Mass).
5. Reduction progress vs milestone equals the current mass reduction % progress (1 - (Revised Total Mass ÷ Applicable Milestone)). Zero or positive values indicate that the associated milestone has been reached.
Assumptions:
Porosity (n) = 0.1 for fractured bedrock
Plume thickness (d) = 30 ft
Initial Average Concentrations (c):
Benzene Source Area = 260 ppb (avg. of MW-3D/5D on 10/16/03)
MTBE Source Area = 1,345 ppb (avg. of MW-3D/5D on 10/16/03)
Benzene Remaining Plume Area = 7.45 ppb (avg. of supply wells 16/62 on 10/16/03)
MTBE Remaining Plume Area = 45.5 ppb (avg. of supply wells 16/62 on 10/16/03)

Date: 3/18/2024
Report Comments Revised Report: Revision 1 Samples have been updated to report to the MQL.
Volatile Organic Compounds - GC/MS Method 6200B
Analyte: Bromomethane QC Batch No: V44813
This target analyte was flagged for recoveries outside QC limits in the associated LCS/LCSD. Data for this analyte is flagged "M" to indicate that results should be considered minimum concentration due to the potential for
a low bias.
Analyte: 1,2,3-Trichlorobenzene QC Batch No: V44813/V43554
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable.
Analyte: 1,2-Dibromo-3-chloropropane QC Batch No: V44813/V43554
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be acceptable.
Analyte: Ethanol QC Batch No: V44814/V43554
This target analyte was flagged for recoveries outside QC limits in the associated LCS/LCSD. Data for this analyte is flagged "M" to indicate that results should be considered minimum concentration due to the potential for
a low bias.
